One thing where most POWER seekers forget ...

NOT HOW MUCH POWER GAIN ONLY .. but WHEN the power gain .. and any sides effect

There was a few so highs .. direct put open pod .. tell me .. ppl says POWER good .. then how come car like dun wan move .. padan muka ..

Nope.. go read up how iVtec works ..
at low RPM .. u wanted to create some restriction on the intake so that when the air goes in .. its like causing some sort of turbulance.. this will ensure better mixture of the Air and Fuel.. remember our engine not GDI .. so mixing the fuel and air plays a cruicial part as well. an open pod allow air flow in like no one business, ... YOU WAN AIR AH .. take la ... so end up the mixture not that nice cause it does not stir much ..

Thats why u look at 4AGE design .. BIG PORT .. suffer at low RPM .. so Toyota redesign the inlet .. the have the proton so call VIM (Variable intake) .. sorry forget what toyota call it d .. its actually to compensate back the big port design .. at lower RPM it uses the long path .. so that the mixture of the air and fuel gets better ... at high RPM .. engine need air and fuel FAST .. dont care mix nice or not d la ... that is when it switch to short intake.. so the engine get as much air asap ...

erm... all that from a non qualify engineer .. whom works for bank ..

u guys better listen up to yang amat berhormat dato prof doctor jaykrupter ..
buy a Forte 1.6 4 speed ... hassle free .. 90% torque at 1500 rpm on ur right foot ..

Nah Pigi baca ..

TVIS

That is what our mivec is helping as well ... not some expert whom tell u mivec open at 4500 rpm ..

track day no . coz u full time full rev ..
but u were talking about not properly shield open pod that causes low/ mid power drop .. im trying to tell .. no matter what .. open pod will cause power drop at low / mid ..

Oh well ... sorry for tat .. im pretending to know something again .. sorry YAB ..

WHAT IS THE POINT ?

manufacturer bukan bodoh ... (but according to YAB .. street tuners.. tune shop .. whatever shop u call it .. all BODOH .. )

KNN do drop in .. so u gain small amount HP at higher end.. but actually drop slightly at front end ..but we cheapskate wanted it cause cheaper to maintain..

If you are going for OPEN pod.. by all means u trying to gain MAX power possible .. dun care low end jo .. so KNN kasih besar as possible la..

Takkan they design something best of both world (for sure require air routing or some sort of technology to reduce the air flow at certain Rpm) ... and sell it at says 2-3k ... YOU THINK U WANNA BUY ?? gain that little bit of power ??

REmember ur car is juz NA 1.8 .. how much u think u can gain by messing up the intake ? 50 ? 100 bhp ? .. u be lucky to get 3 bhp out of it .. few thousands for 3 bhp ? .. go BOT .. so u tell me who the farking b@stard will go buy it ?

** disclaimer : according to YAB , the car manufacturer will give u the best... regardless of cost .. its already the best.

we talking bout the Opening of the intake la.. not CAI ..

If u talking about track use .. yes .. i think they have the kit .. direct replacement of the host .. to the intake throttle .. then with the proper shield.. no CAI if i remember..

but how much can u tahan the low end suffer.. remmember its a 1.8 .. with reduce torque summore .. such heavy car.. u think forte 1.6 4 speed meh

For tracking yes.. u want all that ..

For daily .. instead u do not wan it to suck that much actually

Yup .. temperature do play a big difference.. but the swirling effect does matter..

go google up the ivtec system as well .. thats mixing better the Air and fuel to gain better torque and complete burn .. u open up it .. it does not help much

i strongly disagree ..

if its for track .. yes .. but for daily use .. i can almost confirm guarantee .. no matter how u tune .. the power will drop ..

simple .. u ask those kaki whom change bigger flow exhaust one .. does that helps or not ..
i know an ah beng whom change to 2.2" .. lolz

correct .. if u are going for a track car .. that is .. but we are talking about daily drive with open pod ..

Go back to ur website and see between 2000 - 3000 rpm .. stock or short ramp with what ever CAI .. which one higher ..

daily drive power range is 2-3k rpm ..
and one thing dyno chart never show .. time for the thing to climb

you have not even know where the swirling take effect ...

again . u dun get what the hell we are aiming at .. LOW END!

CAI .. very expensive CAI + un-tune is equivalent to a stock at low end ... (temperature drop so much u only get the same amount as stock)

can u imagine if i put CAI + stock .. how much low end u get ???

do u get what im trying to says now ????

all this summarize that the SWIRL effect does matter.. just that RPW compensate it will COLD AIR INTAKE ... your stock does not comes with CAI ... understand boh

and in Malaysia .. you try stand outside at the road .. noon time .. to 4 pm .. u see u can get 28 degree or not

thats why proton comes with VIM now .. the campro drivablity improve a whole lot .. which mercury doubt it thou ..

u still dont get what we are talking isit ??

what will happen stock + CAI .? (Low end)

u can remain the stock air filter add on CAI ma .. adui .. first day mod car isit ?

my putra stock also we play CAI la ..

we are just PROVING that OPEN POD will kill ur low end ..

and your theory is NOT PROVING that it wont kill .. but u can rescue the low end by CAI (REAL GOOD CAI)

and im saying stock its non CAI also can achieve what you have CAI ..


Nah .. stock filter CAI on a wira

CAI on stock air filter on a SAGA ..

There is no vacuum cleaner in the car .. the effect of sucking air is produce by the piston moving downwards pulling the air in from the intake .. an open pod (BIG BIG HOLE) .. air can flow in easily .. hence ur air and fuel does not mix good .. does not mix good means some fuel is not burn completely.. not burn means wasted .. if u minus out the NOT BURN fuel its like GOING rich .. bcoz u got fuel .. u cant burn .. yet it takes up the limited space within the combusion chamber ... thats why u get the rich AFR ... FAHAM BOH ?

the swirling effect is not happen in the intake manifold.. the intake manifold is guiding the air into the combusion chamber.. the mivec reduce the inlet valve open .. to make it like close a bit .. that is the part where the swirling of the air and fuel happen .. when it run into the combusion it causes turbulance.. hence the mixture better...
