Cold Air vs Short Ram on a TURBO

[BoBbOrAzE]

alright i know this thread has been brought up in the past but i cant really figure out a real answer by what people said. buddy of mine says short ram is better. then on here they say that cold air is better because turbo wants cold air but then again it spools slower? Im confused can anyone tell me which is the better way to go

by short ram do you mean a filter right off the turbo? The only way your gonna get that is if you have a blow thru set up. Otherwise the intake is gonna be in the stock location, ingien, dejon, etc. Overall i don't think it will matter much because the turbo heats the air as soon as it enters anyway.

Ok.
If you go with a "true cold air" intake you will have to have a blow-thru setup with a diff MAF that would be in the ic piping instead of on the intake. Technically you wouldn't want to put a filter directly on the turbo anyways because I bet personally it would get really hot and screw it up or just cause it to not catch particles anymore.

Get a normal 2g intake from dejontool.com and you would be happy with it trust me. It's a very nice intake and you can get it in the color of your choice. Now if you want a cold air short ram you could always take out your passenger headlight or search around the forum for a couple people on here that "modified" their headlamps to where it had a tube in it to push cold air onto the intake.

Now thats a dam nice idea... Very custom too!
Goodluck with whichever you choose.

click here Here is a link to an article where there was some pretty good arguments for and against a CAI. I guess if you are looking for a definitive answer, your not going to find it. The subject has been beaten to the ground numerous times and there are as many people who agree that CAI help as there are who disagree with it. It's up to you to read all the posts and formulate your own opinions. I'm currently in the process of making sort of a duct to introduce a bit more colder air in the area of the filter, my design isn't a 100% true CAI setup but I believe that it will help out with high under-hood intake temperatures.

I never found a definite answer to this either!!! I just try to think, the shorter the plumbing, the less lag..... cool as much as i can afterwards.

Like after u run an open element air filter, sure you get more flow, you also enjoy sucking in all the hot underhood air! I just made a insulated sheild of sorts around the top and right side of my filter....helps on hot days, def can feel the difference in air temps between putting your hand in the insulated area vs right outside.

Yeah, i know HKS makes a induction duct type jobber for the evo's, 'kansai' i think its called, saw it on one somewhere...sweet deal.... It isolates the filter and runs a duct out the front of the hood, next to the headlights. could just fab it yourself, more fun that way anyway

I don't think cold air intake is a real benefit on a turbocharged car simply because its not really going to cool the air that goes into the intake manifold...why you may ask? The cold air hits the turbo and it is instantly heated up again as it passes through the turbine of your turbo. To me the only thing you could get to effectively cool your air on a turbocharged vehicle is a INTERCOOLER.

Cold Air Intake is effective on non-turbo cars more than turbo cars, IMHO. So Short Ram with the air box mod would be my opinion since the air box mod helps keep the engine heat from saturating the filter while still keeping the filter close to the turbo.

Keep in mind this is just my opinion, I'm sure others will disagree.

Your best bet is to make or buy a short direct flowing pipe, build a heatshield for it, and then find a way to feed it with cold air, Then you have the best of both setups
