Hi,

My dad just gave me a second hand Kia Forte for my 20th birthday. I am thinking of fixing a custom turbo system into my car.

1) Can you recommend a workshop specialises in this?
2) Name of the turbo system?
3) Any other additional installations?

Is turbo system:
1) high maintenance?
2) Fuel efficient? - VW's Tsi is very fuel efficient.
3) How much it cost?

With the gearbox that came equip with your car, nah it's not advisable.

1) Can you recommend a workshop specialises in this? Yes... show me the money first..
2) Name of the turbo system? custom made one, u can name it whatever you like la...
3) Any other additional installations? whole system right... piping, turbocharger, intercooler, piggyback ECU, boost gauge, etc, etc.. workshop will let u know, just prepare $$$

Is turbo system:
1) high maintenance? most definitely la.. more then stock n/a
2) Fuel efficient? - VW's Tsi is very fuel efficient. power and Fuel economy should not be used in same sentence for custom turbos
3) How much it cost? depend on quality of items, brand new, used, labor, etc... just prepare lotsa $$$$.... maybe other stuff also need to upgrade otherwise engine BOOM...

go to speedwork. show them the money and let them do the job.

got car for free. another one lucky dude

rm13000 for the kit, another rm10000 for backup if something goes wrong, just drive it as it is, why need turbo? want a turbo car around that price, tell ur dad to buy preve in the first place, not forte

+1 well said

Sappork Spitwork

got free car edi still nt enuf.. want more things.. wth... teenager nowadays..

Sell d kia,buy a turbo car...

With speed comes extra responsibility

lol what with all the haters when someone got free cars?
like that also wan butthurt ke?

I say not advisable especially the lack of technical experts around locally. Yes, you can install turbo into Forte if you have RM5k. Before you do that, consider this list:
- FC deteriorates, the higher you boost the more thirsty.
- If you got greedy and boost higher, it'll overheat easily and when overheat, it'll crack your intake manifold and could also cause engine blown.
- Those air intake piping they do, do these people know how to calculate pressure in the first place and is it optimum the way the turn here and there? Ori air intake is never made straight by carmakers because it is required to gather enough air before pumping into combustion chamber for efficiency. Only P1 make straight air intake which is totally wrong.
- modified car will end up getting low RV, people tend to avoid modded cars especially the wiring, sensors & ECM not ori anymore. Messed up wiring, not many can help but end up living with it that could even led to easily burnt fuse.
- are they giving you wastegate turbocharger, variable geometry turbocharger or twinscroll turbocharger? Wastegate type turbocharger is prone to turbo lag and make sure you don't do last minute sudden brake (around 2000rpm border) as it'll encourage carbon buildup.

Yes, VW TSI, BMW turbocharged, Pug Turbocharged, etc very fuel efficient because they have Variable Geometry Turbocharger or Twin Scroll Turbocharger that eliminates turbo lag. Also, they have engineers that properly measure the air and picked the best optimum design for the air intake piping so that it could gather enough air giving optimum efficiency in combustion chamber. Most importantly, the air intake piping is made of material not affected by heat and the diameter not that thick compared to what those turbo shops piping offer, yet made of metal some more.

Learn turbo first, how it works yadayadayada...

When u want a bolt on turbo, dont bother bout fc.

Again, learn the turbo thing first....

From what i heard, the engine is pretty strained during boosting time

TS, BOT is not as simple as adding ketchup onto your burger but if you're loaded, then it's.

Boosting is very addictive & can easily caused blown gasket or etc if redlining a tad too long.

Getting another car which comes with a snail is far better option.

By the way, i wonder how safe is your driving skills?

Sell Kia, buy VW.

Seriously I'm speechless with all the negativity that surrounds when someone posts asking about bolting on turbo onto their car. Is it that bad? Maybe TS is serious about it and he just needs a point to start. Everybody have to start from somewhere.

1. many shops can do, depends on who you know
2. custom setup where got name bro, you think like japanese car can buy bolt on Greddy kit ka? That one also will cost you 5 figures
3. It's called a turbo KIT for a reason, there's definitely many things that needs to be installed.

1. Not really as long as done right the first time. Maybe just change the oil more often(instead of 7k, change at 5k)
2. depends on your foot. how much fuel you use depends on how much power you use from the engine. if you kaki binary keep boosting then your FC definitely will go down but if you just drive normal, your FC should remain the same or even better than stock.
3. 5k onwards to 5 figures depending on setup.

your concept about cars and how turbocharger system works is totally wrong. Technical experts you can refer to others who had already done it(as can be seen, there ARE turbo'd Forte's running around already), research online what others did overseas, research around BOT users from other cars as well.

- As mentioned previously, FC depends totally on your foot. You take a Golf GTi 2.0 and whack all out touge in genting and watch your fuel burnnnnn
- Usually overheating is not much of a problem, the problem about boosting high boost is whether your engine internals can take it or not. Pistons, conrods, crankshafts etc which is why you see people swapping out their pistons/conrods/crankshafts/gaskets with something stronger if they really go serious into their turbo setup. Intake manifold crack? HAHAHAHAHAHHA!! Exhaust manifold crack ada lah which is either due to shoddy welding during the fabrication of the manifold or your exhaust temps(tuning) is way too high which your pistons will melt first before your manifold will start cracking. And usually people engine blow is due to the head gasket giving way, pistons cracking, conrods or crankshaft snapping, but definitely not manifolds cracking.
- Air intake pipe cannot be straight? You gotta be kidding me. Explain why people go for ITB(Individual Throttle Bodies) then. It's basically sucking air direct from the atmosphere, no bends and whatnot. heres a video with ITB and standoff injectors.

- A properly done up car can actually get a higher RV than a normal car as long as it's properly done up. If you want you can even remove the kit and demod the car and the car will be as good as stock, plus you can earn back a few grand from selling your turbo kit.
- you know alot of technical jargons like wastegate, twin scroll and VGT but seems like you have zero clue on what those are or even means. All petrol cars running turbos requires a wastegate, be it internal or external. VGT, twin scroll are technologies which improves turbo response and performance. Since all turbo's have wastegates, do explain the relationship between wastegate and turbo lag then and also i'm curious about carbon buildup if i release throttle at the 2000rpm spectrum.

I agree that newer cars comes with new technologies that reduces turbo lag and improves performance but things that comes out from the factory isn't exactly the best. They're designed so that they can be massed produced cheaply and effectively while still able to do it's basic job, albeit not the best. Many forced induction cars(4g93T GSR engine and Preve S4PH-T are good examples) have rubber hoses as their intercooler piping which expands under boost and this expansions robs about 500rpm before full boost comes in which is why many people replace it with stainless steel versions and Samco elbow bends which won't expand under boost. Stock exhaust manifolds are also cast iron. Swapping it out with a custom-made tuned-length 'banana' manifold will increase performance as it enhances exhaust gas flow to the turbo providing faster spool-up. Long story short, not all things that comes out from the factory, designed by 'engineers' are good, there's always space for improvement.

Agree with this statement, i suggest TS to study on how turbo system works first and all the parts needed, at least it will save you face by preventing you asking stupid questions to veterans who knows their shit.

the Forte in the video is an auto and the auto GB robs alot of HP from the car. A Polo TSi may win it, but hey, it's still faster than most NA cars on the road and can easily tapao a Vios.

My 2c to TS is to do your own research and what you do is totally up to you as it's your car anyway. But before you do anyhting, make sure you have enough knowledge on hand and don't regret whatever you have done(unless you've done something really really stupid) As you can see, many of the people here in this forum are just keyboard warriors who knows jackshit about the technical aspects on cars. Long gone is the time where this forum used to discuss technical stuff like cams and engine design, now it's just a place where people compare cars and ask what car to buy with a certain budget.

long post, bye bye

edit: btw, please do NOT get your kit from Xenon. just google up their name and you'll know what i mean.

lets see how jayraptor reply you

JayRaptor knows SHIATss about BoT
(wat an IDIOT)

STFU jayCraptor

Where is my 50kg metal bar?

Please la.. Waht do u know about turbo?
Jayraptor got fren working in automotive industrial. He knows more than u think... And all those jargon wastegate apa apa gate those info u guys have is all wrong.. Lets hear professional advice

We know viostrd turbo can tarbao Nissan GTR. Dont need to remind us

Anticipating crash in 3, 2, 1...........

Your first car and you want turbo. Why not drive the car as it is?

yah lo, sumore said vios 0-60mph can run under how many sec ar? 5 or 2 sec ar?

Go faster stripe stickers reduce drag & each sticker can increase hp by 75%! Lexus badge swap can increase RV.

Kalah LFA.

ahhh, you beat me to it. i was about to reply that jayraptor till i read ur post. good reply.

What's up with Xenon? I googled 'xenon motorsport' and found nothing negative, at least for the first few pages.. didn't bother to look further..

It is not that bad about bolt-on turbo, generally there's too much negative impression about the idea before the discussion get anywhere serious.
I would agree that TS should discover some basics of turbo before proceeding because once you're not operating the car in a standard way, you're on your own.

b4 you even contemplate this...do you

1) have spare cash lying around? at least 3-5k (assuming nothing blows up)
2) do you have the time to spend weekends at workshops?
3) do you have spare transport while the installation takes place?
4) do you have additional funds to upgrade the braking system to take into account the extra power?
5) are you willing to read up on your own, and have at least basic knowledge of how a BOT works so that you dont get your throat cut?
6) willing to leave your car at the workshop for weeks/months? to troubleshoot etc?

if yes to all above...welcome to the fun/frustrating world of modding

I think just prepare 15k for proper turbo setup

-management(Haltech SP500)
-intercooler piping
-wastegate
-tonnka turbo manifold
-BOV
-good turbo
-bigger injector
-walbro fuel pump
-engine oil cooler
-Boost meter, engine oil pressure meter, engine oil temp meter, water temp meter.
-atf oil cooler
-double layer radiator
-get better brake.

this setup is kinda safe for 0.5 bar boost.

if u want higher BOT, u need to start to work on your internal.

No.1 criteria... you need to have lots and lots of $$$$$
No.2 criteria... more $$$$$$ when No.1 runs out

A case study for my own car..

Expected
After 1 year++ of research decided to do a few relatively simple N/A mods.. estimated cost with buffer.. RM12K.. that should be done in 5 days, max two weeks..

Actual
RM30K++++ 4 months...
Still a few more problems which we not sure how to solve
which for sure need even more

fella still haven't wake up yet kot

i sense sarcasm

How fast a BOT'd car is depends heavily on turbo setup and boost level. I bet the vide you're talking about is this video



If you are talking about this particular car, the amount of money spent for this setup can buy you a brand new Myvi edi, cash. Full boost comes in at 5000rpm which means the turbo must be the size of your head already and highly un-drivable.

Even a simple BOT kit with a small RHF4 turbo at 0.5bar boost can increase the power by at LEAST 50+hp and that's easily faster than most NA cars on the road already. Which Wira turbo you're talking about? 4g93t gsr engine? 4g91 BOT? 4g92 BOT? 4G15 BOT? Or 4g13 BOT?

If you're saying it can't be done because the engine is weak, that is also bullcrap. Have a look at the Campro engine, famous for it's snapped crankshaft during the few first batches and also it's weak aluminium block and weaker than usual conrods and pistons. still not stopping hundreds of people from bolting on turbo's onto their ride and one even manage to squeeze 380hp out of it, though the money HE spent is also way into the 5 figure range...

tulan edi people coming in being a wannabe expert in the field.

looks like many of the posts got nuked already. Last time Xenon got their own forum and many people complained in their own forum where they cheated them money and stuff but it got deleted. Ask around s4ph-t group in FB and you can hear a few stories and also here in LYN as well some people kena from them already. It's not the problem with their kits, but with the salesman.

out of the 15k, the most expensive ones would be the management, tonnka manifold and a brand new good turbocharger.

The expert is good in reading brochure..
He knows almost everything..
Some of us only comment what we know.. But he knows everything.. I mean EVERYTHING

Dunno... I heard much much more was spent on that car... One trailer full of Myvi is more like it..

you know, while i agree that one should do self study/research themselves instead of being lazy and just get spoonfed, i also think it is damn sad case when you have to "save face" on asking a question regardless how innocent/stupid they may be.

while the general direction of F&F has swayed away from the technicality discussion (especially when technical talk sub-forum was still around, i REALLY ENJOYED that forum a lot and never bothered with F&F main forum much because it's just spams of car clubs) however won't you agree that at least know F&F is much more appealing to the masses instead of just elitist (keyboard warriors or genuine know-hows alike) showing off how awesome they are at cars?

you know what i mean when i say that whatsapp group chat

From my limited knowledge, that bot is more likely to have higher fuel consumption under constant speed cruising, and it is different then using smaller turbo engine for the same car (e.g. 2.0 na vs 1.6 turbo trim). The old turbo system is generally running at richer fuel so that engine is not overly heated at high boost high rev, I'm not sure on the latest tech in map/tune the fuel mixture. And i think ultimately the sifu will tune the engine to customer's need, like high end power or better torque or...

Nightstalker1993dont need take your precious time to reply that joker, he wont accept it, what he will do is insult u .

yes, management>turbo>tonnka but i think my list gives quite a reliable for long term usage. always monitor at the engine oil temp and also oil pressure. if its too high u better drive slow and stop boosting.

i forgot to mention u need to find the sweet spot between 7 to 13 row oil/atf cooler, the bigger u buy, the lower the pressure, if the pressure too low the oil might not reach the place it suppose to be, the effect will be worse then before adding oil/atf cooler.

Happy BOTing.

well you can slowly read his blog and slowly calculate how much he spent. That custom spec turbo alone is definitely costing a few thousand buckaroos.

forum is a place to learn. those with lack of knowledge are encouraged to read through older posts or use the search feature before posting which is highly enforced in international forums(be it automotive ke, android modding ke, technical software stuff ke). the 'elites' are usually laid back and low profile, only coming in when situation calls and rarely do they 'show off how awesome they are'. Those who do are usually wannabe's anyway.

well honestly how efficient a car is depends heavily on it's tuner and tune settings plus also the owner's driving style. Most people say turbo cars are heavy in fuel consumption but then once you sit in their car for a cruise through town and you'll instantly know why. After getting turbo'd, their right foot becomes heavy as they get addicted to the boost which robs your fc. Drive it in vacuum when you're cruising through town and the FC is a totally different story. I can cruise at 150 on the highway and still remain in vacuum the whole time though the FC at that speed is still crap since the wind resistance is alot higher. Optimal FC i've tested is actually at 80km/h. Constant highway cruise at 80km/h gave me 6xxkm per tank while travelling at 150-180kmh gave me a full tank mileage of just shy of 500km.

I've ran my 1.6 engine with a turbo meant up to 1.3 and although the top end is crap, the low-mid end is definitely fun. Turbo starts spooling at 1500rpm and full boost comes in at 2500rpm making it perfect for town driving and overtaking as I don't need to downshift as often. This flexibility in choosing turbo's for a BOT system lets you have a choice in which part of the powerband you want to focus more.

nehh don't really bother if he replies or not. Needed to do something to get me sleepy anyway. If you noticed, my previous post was posted in the wee hours of the morning

+99

lag until 5krpm? no thank you, no one need that. LOL!

Nightstalker1993 i dont think he even dare to read your reply anymore hahaha

How fast is the fast u mentioned?
How low price car is the cheap car u mentioned?

Since TS asking for advises whether to get Turbo, you are the devil while I am the angel. Ofcourse, 1 support 1 against. Those custom shops you mentioned, do they even know anything about pressure and air density in the first place? Do they know how to calculate the most optimum flow? Those piping are done with proper measurement or just copy and think got the style means ok. You can set air intake straight but it will not draw the highest volume of air with optimum density before pump into engine. You could draw lots of air but not highest density end up more fuel guzzling.

Excuse me, Forte 2.0 NA will get better FC than turbocharged 2.0L. This is fact. Also, the FC depends on how high the boost. If boosted to 2.4L engine strength professionally by Kia, it'll consume less fuel than 2.4L NA but still higher than 2.0L NA.

When comes to hands of Ah Chong or Ah Meng modify workshop, Lol!! Whatever they do, they are nothing close to what real carmakers could do in reality. Only end up with high FC and more horsepower but less torque. Vios is not made for performance and it is nothing more than a city car. Why take that for comparison?

Do you know what are the function of VGT & Twinscroll Turbochargers in the first place? Ever since these 2 types are introduced, those normal turbo we all know are now labelled as lower level wastegate turbocharger to differentiate clearly from the 2 new toys. What do you know about turbolag?

Pug508 1.6T
output 156ps@6000rpm
torque 240Nm@1400rpm

The turbo activates from 1400rpm onwards. If you think below 1400rpm without turbo assist is lag, that is wrong. Turbolag happens when the turbocharger activated and while operating at 3200rpm and there's sudden deceleration, the pressure from exhaust become low and to allow the turbocharger to continue spinning optimum, the VGT would retract the blades for low pressure mode continue to draw in air. Twinscroll type in BMW has 2 vents, 1 for low pressure and that allows the turbine to keep spinning under similar situation. The older normal wastegate type can't do this.

Talking about maintenance & reliability, do you know those who knows nothing about pressure would end up choking the engine. In long run, wear & tear faster and more often, requiring more cleaning.

Nightstalker1993 , nah kan.. Expert is in the air!!

I'm curious on how much more horses Haltech SP500 can produce compare to Emanage?

By the way, with such moolah, getting a halfcut is even better

What?? Turbo lag will cause deceleration? No offence bro, i didnt encounter such thing leh..

Actually the management system dun make power
the tuning yes..
Some products can have larger map resolution where u can tune more .. More rpm range smaller interval.. Higher boost control and so on.

hahahahahahahaha, pls stop making you more looking like a fool lah. i wonder have u ever own and maintain a turbo car your own. (dont tell me mere test drives) do you even ever mod a turbo car? do you ever understand how turbo works? omfg. LMAO!

This post has been edited by Gouki: Jul 23 2013, 12:25 AM

lolz, that craptor from AW forum, nvr failed to entertain use

Tonka or Tong sampah also the same... everything is depend on tuning and matching! What is Turbo and what does it do and why supercharger... well there is a long way to learn however it is interesting which is better than reading bible.

What i would say is efficiency! if you say NA runs more efficient than a Turbo charged engine well tomorrow i will be at the Church.

I Agree.... Sell this ride buy a Vios and live a so called normal life

Or maybe after get a vios, u can pump in turbo which kick in at 5k rpm onwards.
The result, u get plenty of sihamz + godlike torque n horsepower with durable 4at + good fc + most important nice rv

i dunno a thing from the previous page & not intend to read it.. but if ur interested on bot ur forte.. go google or yahoo it up.. from a fellow friend of mine who owns forte.. there are tons of information about it out there.. as people from europe & US bot their forte the first day the car being sold there~

Yup with Vios u can get

1. Si hams
2. Lala
3. Ohhh Chen

Sometimes with bonus might get LP

btw.. my NA auto gearbox Waja fitted with a set of heavy 17" lowered down to the point the base of the car hit every speedbumps out there.. can tapao ur vios anyday~

i like si hams.

Dammit.... you are really STUPID! I tot they just joking around...

eh you completely missed what i was trying to say, nvm la lol

Honestly I'm pretty lazy to reply this as this clearly shows your lack in technical knowledge. But since it is already 5am in the wee hours and I need to waste some energy in order for me to sleep, here's my post.

What you need to know about pressure and density? Ideal Gas Law? Boyle's Law? Charle's Law? Seriously? And talking about intake, you say straight air intake won't draw in as much air as a 'bent' air intake? Those 4age's 1600cc are pushing more than 200hp with that setup and you're telling me it's not drawing enough air? Let's go to Jet engines then, direct ram air intake. Anything to say about that? It's still basically a 4 'process' engine as it still requires intake, compression, combustion and exhaust, just that it does it all at once. Air is sucked in direct from the atmosphere and it makes use of the ram effect at high speeds and altitudes.

You're saying the efficiency of a 2.0 NA will always be better than a Turbocharged 1.6L with the same power as a 2.0NA. Seems like you're missing the knowledge about volumetric efficiency here. Turbocharged cars will always be more efficient than NA engines as the turbocharger is harnessing energy from the exhaust which on an NA engine will be wasted, then using that energy and compressing air, forcing air into the cylinders, increasing it's volumetric efficiency. About FC, as long as you drive in vacuum during normal town drive your FC will remain the same or even better than when NA, and will definitely be better than one with a higher cubic capacity.

Reason we're comparing with a Vios is because the Vios is basically in the same category as a Forte, a basic everyday-drive point A-B car. If a Vios can be turbocharged, why not a Forte?

Yes I do know the function of a twin scroll and VGT, I'm just afraid that you don't. Seriously you're making a fool out of yourself saying 'wastegate-type' turbochargers are old school tech. ALL turbochargers used in petrol engines needs a wastegate else the boost level will just climb as the RPM increase until the engine kills itself from overboosting.

The way you're describing 'turbo lag' is as if you're describing a supercharger. Activates and deactivates? Bro, a turbocharger spins even when the engine is idling. When a turbocharger starts producing usable boost is a whole different thing, it doesn't 'activates' and 'deactivates'. Newer technologies can start producing usable boost at an earlier RPM than older turbo's with older technologies and hold that boost throughout a longer RPM range than an old-school turbo, but the way you describe it is totally wrong. What vents for low pressure and high pressure? All VGT does is changes the A/R ratio and exhaust flow in order to compensate for low-rpm and high-rpm driving thus creating boost at a lower RPM and then changing the nozzle angle to accomodate higher RPM operations. Some VGT Turbo's in Diesel applications do not require a wastegate as they don't rev that high anyways and does not produce that much gas flow but most petrol engines do. Volvo's VGT turbo's does have a wastegate built-in and a twin-scroll turbo definitely have a wastegate built in. They're taking technologies that had been long used in the aviation industry in jet engines and finally putting it to use in the automotive world.

For those who don't know what's VGT, HERE'S a simple description on what VGT is. For twin scroll, it divides the cylinder exhaust gas, thus seperating exhaust gas pulsations and improves the scavenging effect in a 4-stroke multi-cylinder engine. And yes there are also split to a small and large turbine for lower and higher engine rpm efficiency.

About your last paragraph, so basically a bolted-on turbo engine will die because it would choke the engine, eventhough with a turbo you're basically forcing air in? What a joke. I do agree that the wear and tear in a turbo engine would be slightly higher than an NA engine but with proper maintenance, both NA and turbo engines will last pretty damn long. What cleaning in specific are you talking about? Throttle body cleaning? top overhaul? Engine bay cleaning(LOL)?

Before you comment any further, do share what car are you driving and what car had you driven? Plus what had you modded on your car(or any cars) in that aspect? I see you have an atrocious reputation in AutoWorld forum i see

Anyways, good night.

My advice:

Get the car first, drive it for a few months and then think about whether it suits you. If it doesn't, then beli lah siput.

I seriously doubt he can understand..

Drive in vacuum.. He tot u saying vacuum cleaner later

Spending is not a problem, how much premium parts did the owner killed. LOL

The function of turbo does not control your tuning. During cruise, your NA engine does not rely entirely on atmospheric pressure to suck in air. it's assisted from the turbo's recycled exhaust energy. FC increases when there's alot of air pushed in and the management needs to keep the AFR at a safe threshold. Well put it simple, when you push for power, your FC drops but your car goes faster. People always misunderstood thinking that you can get more HP while maintaining low FC. Good FC comes when you're light on your foot.

Later he show you Prius Hybrid then you know.

Lou poh.... or.. "that thingy"


You guys don't bully him, later he call his father (Jay Leno) to teach you all a lesson and his brother (Jay chow) to show you all what is piu yee.

Lols Hybrid lain cerita lah....... but highway also die for certain hybrid unless smart dual hybrid only works well....

You wont know his ability to create story out of brochure! Its juz .." The amazing brochure reader".
FyI , he have world wide brochure! Especially thailand which is more accurate according to him (not accurate yet)

Come race.

014-6228620 outside settle

Actually after TS asked in the first post, he never made any more comments.

You guys are wasting your time in giving advice, so am I.

TS asked you guys to fill in the blank but all provide essays. How to digest?

Now is the battle of twinscroll/VGT snail & old-school snail.

lols others members here just enjoying bashing and trolling around helplessly hahahahaha

yup, eating metaphorical pop-corn while reading the thread

only after buka pose can do that lols during this hour everyone tahan...... siput babi pun siput babi lah

No choice.. kenot help it ..
tried to logic and reason with him .. but end up all sorts of nonsense came ..

If logic and reason dun work .. troll him better.. lolz

Emm... just hope that if someone, who is not very clear on something, please don't post statements like one knows everything.

Actually it would be a healthy topic but those half tong air ppl masuk hancur edi.....

BTW the xenon BOT forte is really slow freaking slow even my 1.3 satria BOT can makan him kaw kaw.... from the video i can predict, this car might be using piggyback and oversized turbo.

1. Regarding blowing your intake manifold. If your intake manifold can take one bar of vacuum, why cant it take one bar of boost?

2. Looks like a copy and paste. Turbos spooling at 1400rpm, exactly 1400... it's a copy/paste for sure.

3. Exhaust gas is heat, wasted energy. recycle energy via turbocharging, more power.

4. On cruise, turbo atomizes air thats going into the intake.

5. If you can retrofit a VGT without any hassles, goodluck.

6. God created turbolag, we created VGT, EFR, Twin Scroll, Plumb back BOV, ceramic wheels, ceramic bearings, ball bearings, billet wheels, ti-gamma wheels.

7. It all boils down to your personal preference, wether you want top end power or low end torque.

8. I did not read much of NS replies nor your rants.

9. Sizewise on pipes, what do YOU know? Can you tell me both results of having both a big and small intercooler pipe? Can you TEACH me on how and when to use a big or small intercooler? And what about exhaust sizing?

10. Can you read a compressor map? These are to aid tuners and hardware installers in picking and matching turbo to engines. I've seen starlets with kkk turbines boosting at 1.5bar, making less power than it did at 1.2bar.













And of course, I've snapped my turbo shaft before in the learning process.

HAHAHAHAHAHA God created turbolag lolsssssss tak boley tahan lols

exactly what i had in mind. lol. to add on, VGT and twin scrolls turbos do not eliminate turbo lag, they only minimise it. there is still turbo lag no matter what. and when jayraptor said turbo "activates" after 1400rpm in his pug508 example, that's turbo lag before 1400rpm. and jayraptor, do u know this puny VGT turbos has it downside too? they tend to lose their breath earlier when approaching redline?

Turbo, VGT, EFR..... bla bla bla... just learn how to see the island map... simple as that.

VGT not so suitable for gasoline engine because high temp! VGT normally survive below 500c. Diesel is cooler because the exhaust emitted gas temperature mostly are residual unlike gasoline engine which the temperature will climb up to 700c

one of the best one! LOL!

How do you arrive to the conclusion that turbo start spoolling at 1.4k rpm & instantly generate peak torque?

I langsung cannot brain your definition of turbo lag.

one of its kind lols

well spoken by the god, Elthor. (in b4 some post his picture with a hammer )

Well for the 1.4 TSI the peak torque does kick in around 1.4krpm to 2krpm IINM. Need to dig out my dyno graphs to show. But I agree, with these setups, it definitely runs out of breath at the higher top speeds.

Yes indeed. But jayraptor make it sound like turbo spool at exactly 1.4k & instant torque. Then the dyno chart would show the torque curve look like a perfect brick shape.

That would be hairy to drive slow.

to jayraptor's understanding, turbo basically "activate" itself at certain rpm set.

I sort of think that he "Activated" us

Awesome post but i doubt the fella understand anyway
Nothing much to add

Jaycraptheory never heard b4 meh? 1.4k rpm instant high speed spin, powered by jaycraptheology innovation vgthai from thailand with kerb weight of 50kg.

observant!

His tech very weird. If I hit 3.2k not only I get turbo lag, my car would decelerate. Worst than old campro torque dip.

Nono, with his innovation, he means when u decelerate at 3.2k rpm and u wan to accelerate back, u will feel turbo lag becoz his system only.activate full speed boast at 1.4k rpm. Thus u need wait ur rpm drop back to 1.4k rpm first only u accelerate. Oo man.... u still need learn lot from jaycraptheory.
