Turbocharging an engine may not result in better fuel economy but it makes the car more driveable with max torque coming in at low rpm. This makes it much more fun to drive and safer for overtaking plus you will feel less tiring driving a car with adequate power over long distances. In Malaysia our road tax structure means that turbo cars are more practical to upkeep than large cc cars.

It isn't new technology as European cars have been using it for so long but the Japs have been slow to adopt it. I think it is only due to Koreans pushing ahead with turbo that the Japs now feel compelled to go turbo too for fear of being left behind. Even then it is only Honda tip-toeing cautiously into this field with lightly boosted turbo and frequent reminders to service in case their engines explode while Toyota, Mazda and Nissan are still locked in the past as far as our market is concerned.

Previously to drive a powerful turbo car you need buy a Conti car with scary reliability and costly maintenance. For non-luxury segment that would be a VW, Peugeot or Ford and for luxury segment a Merc, BMW or Audi. Such cars are not for the faint hearted or the not so deep pocketed. You can drive a powerful Continental car but you drive in fear.

But the game has changed with the Koreans adding turbo to their C and D segment cars. The Optima GT puts the exhilarating power of a 2.0L turbo engine within reach of mere mortals. The beauty of its styling is matched by the beauty of its engine. Korean cars have arrived and they make no apologies for their quality and features. Those still mired in brand snobbery against Korean cars can give way to the Optima GT zooming past while sedately driving their NA Camrys and Accords.

Yes boss. Understand. So how u know it is a GL spec factory manual.. lolzzz
U can't even difference what is a trim and a chassis..

With @wkc5657, I treat him as non-tech savvy person since he claimed Optima GT and Elantra sport gets turbo assist from idling and below 1400rpm for Optima GT and 1500rpm for Elantra sport.

Same case with turbo, at low rpm masuk bypass inlet, higher rpm masuk turbo inlet.

Tak paham, eh lu mau otak kau kasih tendang sampai hancur dan kena lempang beribu kali baru insaf ke?? 

Grandmaster already give enlightenment using TVIS example by putting aside the inlet and just go straight into the low and high pressure scroll. This is the how twinscroll turbocharger works!



That means got 1 dedicated valve to control high low exhaust pressure flow you know?  Get it??!!  

Oh man, laugh until almost pissed on my pants.

Eh since when twinscroll turbocharger has high pressure and low pressure scroll ah? What happened to sequential turbocharging geh?? Twinscroll is mainly to reduce interference of exhaust pulses that thereby increases efficiency of exhaust evacuation and improving spool up la...

dares got new sig worthy quotes  This joke is quite sophisticated, initial reading like macam betul. But after looking at twinscroll turbo diagram, i don't know whether can stop giggling if driving a "twinscroll" turbocharged car.

Grandmaster also decreed that the split second 800-1400rpm range performance is THE determining factor that make or break the engine to be categorised as junk shit category or top notch approval that he will buy  :thumbsup:

Such a drag race that lasts around 1 second, wonder how much ground covered?? 10 meters?

My car DCT won't allow me to up shift at 1400rpm in 4th gear even in manual mode. There is mechanism to prevent engine stall. 1 -> 2, maybe. I doubt 2 -> 3 is allowed, can try it out when free. However must press the gas paddle so lightly else gear 2 reach red line too fast.

Probably whichever car that have higher gear 2 or maybe gear 3 top speed will win. Both drivers struggle to up shift at 1400rpm, lol. This plug from sky hypothetical experiment not practical at all.

In fact I do understand difference between trim and chassis. However the Lancer GT sold in Asia is not just trim but slightly different chassis from Lancer GL chassis which is why it could still sell with strong resale value despite existence of rebadged inspira.

I think the ECU/programming prevents the driver lugging the engine, not engine stall.

For preventing engine stall under low speed, it can just disengage the gear/clutch.
Oh well, I'm not the programmer so it can be either one, or both.

Maybe you are right, I didn't thought of the lugging situation.

The thing is the cars today are sophisticated, with electronic throttle control the ECU might gradually open the throttle when driver trying to lug the engine. There are many options with the modern electronics.

I also guessing, might be combination of all like you said. Won't pretend to know all.

So ur "i do know" big finish lo.. Lolzzz
Do u even know the lancer gt was just a poser as the big chrome bumper are meant for ralliart as than front bumper allocated space for the intercooler. In us or japan it comes with the normal bumper.. Sorry bro.. U know nothing.

Strong resale value? How long have u been living in a cave? My fren drive a lancer gt try to sell off it when 5 years old (2015 time.. No delear wants to take it.) they take as low as 55k.

If u go search in mudah, inspira 2011 cost like 40k+..  Lancer gt same age cost like 3-5k more.. But the fact new car 30k more.. Which cave u stay? Lol
Admit it.. U know nothing

As per MMC tech guy who showed me the details on lancer GT and Lancer GL chassis, they both have different code to mark the difference on both chassis. Whatever conversion mode you did to your Walancar is only cosmetic appearance. Like this photo from mudah, there's this modded fake lancer selling at few K difference from real lancer GT, but will people buy at such price when they could get original stock lancer GT with no mods done. If lancer GT worthless, the Lancer will be priced at no difference from fake Lancer like old perdana vs Galant 1994 where the galant rv suffers since eternal rebadged.

However, the Lancer and your lancar are already dated and old. People look forward to new Civic, Altis, Mazda 3 for better long term ownership.

As for modded cars, non of the modshop people are high level engineers equivalent to those in manufacturing cars. Like you for example, you replace original technical parts with custom mods (not from original lancer parts) that never really been through extreme R & D testing. The car will run but how often do you check under bonnet compared to those who stick to original stock cars in long term. How come you check far more than others? Because these mod parts are never perfect that even you don't trust they are safe. A car with serious leakage, noise, rattle, torque loss, suffer serious high FC, bad mixtute with black smoke can still run as long as you refill all the fluids that have leaked off.

Looks like you're the only one still don't know what's going on. The rest who came here to bash or correct my statement upon seeing your post first, after that they stopped after noticing the hints and actual info that I intended to pass. Your lack of knowledge post on turbocharger effective operating rpm just gave my buddies some idea. Those smart forumners who came including your buddies already notice the whole turbocharger in detailed tech talk is just a blunder to draw them into this thread and make them read the actual point and message that I'm trying to pass.

Since your brain level is the lowest here, the main focus is the turbocharger ineffective rpm part which is also the most important for most car owners in traffic congestion. Yes, most would idle or just light foot on pedal which determines FC. In America, the new Camry 2.5L and Accord 1.5T (tuned for torque) both beaten Optima/Sonata 2.4L and 2.0T (tuned for power). You may say Optima GT has the power when its turbocharger able to draw high dense air in from 1400rpm onwards but do you know that it is already burning more fuel at this stage equivalent to 3.0L engine as per tested by buddies in America on leased test units. If you wanted to say, Accord 1.5T is turbocharged, it's tuning and configuration is towards torque and fuel efficiency using as much fuel as 2.3L car only.

Once again my buddies would like to thank you for helping in their upcoming project. Though they had me sacrificed a bit for using blunder to draw in viewers, as long as it works is ok. Number of viewers really skyrocketed these short few days. This is what people call smart marketing, using your foes to get the work done. When their new products launch, which D segment model will your Korean product planning bring in and how to compete Japanese rivals that already created obstacles and barriers on the road the Koreans cars wanted to go.

I noticed his new pattern

When his "facts" kena ripped apart until he cannot defend it, he will putar halim say he "dumbed it down" for others

And then he putar to something even more wrong than his earlier assertions

AND he still has not answer my question.

I didn't better to read as u know nothing.
Yesterday story, chassis code difference. When i show chassis code how to define.. U cant differentiate between a trim n the chassis indicator. Now bring up mmc personal. Is he a salesman?  I think should be ur imaginary fren.

Conclusion doctor jayraptor know nothing.

And now try to driver old design.. This n that.. We don't cave. My point is just to prove u know nothing. High FC or not is not the discussion.. Just wants to show u know nothing.. Don't need to divert.

The now divert mod lagi.. 3 years ago u stated well all have problem after mod.. Won't last.. Check or not is not ur business.. Is u know nothing.. U said urself 3 years ago it won't last.. Now divert story.. Need more checking.. Etc.. U know nothing.

Until now you haven't specified the chassis code for GL and GT. Looks like only source you have is service manual of Lancer GL. Divert mod? In still sticking to your mod topic. You mentioned you took custom ECU for your Walancar apart from changing the cosmetics, maybe the steering wheel and suspension set. Anything else apart from these? Non-technical part no worry. Custom ECU with specific tuning setting will only reset to default if power supply cut off.

Did you replace the stock air intake and exhaust set with stupid custom 1? If you did, most likely the low end torque deteriorates, need to press more pedal than usual whenever moving at low speed, weakened further with the weak old generation CVT gearbox. Also your engine will suffocate from the weaken pressure from air intake resulting in less collective dense air. Same case with the exhaust part, the out pressure down.

Modded car doesn't always breakdown. Most likely having to press pedal more, getting poorer FC and getting more carbon buildup in intake and exhaust manifold, valves. You love maintenance can always clean up. Still cheaper than v6 engine cleaning cost and labour charge.

For others, I'll advise them to keep a car stock and original. If modify also only change bumper, lights, rim, etc to high spec trim or new facelift is ok. Else, save money better. Later on can buy new better car. If mod car like you, after 10 years also still stuck with old junk that is suffering from serious wear and tear compared to stock model of same year.

Oh wow....turbocharger then spin to marketing positioning la, your buddy testing la, whatsoever....

Eh, orang kasih suap spoon feed you easiest understanding twinscroll and when you "apply" your understanding to "refute" me, some more salah big big time

40 years of understanding, great....the more you say, the more you bongkar sendiri how "much understanding" you actually possess....

yala yala yala, your gang damn geng. Tuning preference pun kasi "scientific full analysis". You being the most senior among them this kind of "technical breakdown", your gang must be even more damn super top notch geng. This split second fuel consumption also another category to make or break engine to be junk shit category is it?

Your geng real or imaginary, doesn't matter. If real people with reasoning actually can accept your "technical expertise" and "deep understanding" from 40 years berguling in the industry, further laughable can conduct such a "groundbreaking" fuel consumption analysis.

There are professional companies doing complete tear down analysis like this :

http://leandesign.com/

Everyone looking into each other's product. You and/or your gang's supreme spec analysis is really better than this? Come on la....the archieve report itself cost more than the car you drive. How much more does it cost to engage a new product analysis? Even if in house team, you got "face" to share your insight like this?

I must really salute those supervisor (real or imaginary) that entertain your "analysis".

Eh...You saw the reply just above and also before? You "twisted" his words, the split second drag race is from idle standstill to 1400rpm, langsung tak payah masuk/tukar gear. Masuk gear 1, lenjen sampai 1400rpm, buat ukuran jarak/dynojet/"torque" feel. Faham??!!

Oh good heavens, the mazda6 2.5 is (whatever number) meter ahead of the optima GT in this split second drag race!!!

This is what makes or breaks an engine to be categorised as junk shit category or damn good approved will buy  :thumbsup:
