Cai?

[1fast97gsx]

I just got a front mount intercooler and I am upgrading turbos again as well, so I was wondering if it would be worth it to make a cai since the space where the stock intercooler sat is now open. I have to get a new intake anyway because of a bigger inlet on the new turbo so...

will cai hurt because of the long piping?
would I gain any power?
is it worth doing?

Thanks

how would you lose power due to length? jdmawd has done this. seems like a ok idea. rain driving isnt really an option however.

Well wouldnt you rather suck in 80 degree air and compress, rather than hot 120+ engine bay air.


Cooler intake temps means lower charge temps as it exits the turbo, which means less work for the intercooler, cooler temps leave the intercooler than before. Cooler intake charge = more power.


On top of that you get a very sweet sounding turbocharger under boost, and if you route it like me or jdmawd did you will get a ram air type effect, potentionally helping your spool time between shifts because your turbo always has a (small)positive force against it. While your moving at least.

Pipe lengths do make differences on NA cars so I imagine they would also have some kind of effect on a turbo. I personally have no idea what a long intake pipe will do for a turbo. On a NA car though, longer intake pipes do reduce low end power.

I too was thinking about doing this. Make a custom intake pipe that drops for the turbo to one of the openings in my front bump (95 smiley) and use the hks filter I think it is, the mushroom looking one. The reason for that being the top or front of the filter has a wide area that collects air so when facing forward it will cram more air in there. Ive seen it done on a 1g before.

ahhh here we go, jdmawd's CAI.

Anyway, I figured there would be more bends and a longer pipe, and as stated on NA cars you would lose low end power with this ... not sure about our cars. That's why I ask

weird it was there yesterday

1. Not as long as the MAF stays where it is.
2. Depends on where your current setup draws air.
3. Yes, if your current setup sucks air from under the hood. DSM ECU's (1G's at least) retard timing after the temp sensor in the MAF reaches a certain point. (~105 degrees) This has nothing to do with intercooling. Get a pre-filter for the K&N and you have to worry about water, unless you submerge the filter totally. I draw air from behind the passenger fog light hole and don't see a drop of water in my intake tract, even in rainy WA.
