you do know that CAI's actually decrease power on our motor...right? just use a short ram with a pop charger...

isnt their a dyno or w.e on here with the short ram and cold air difference and the cold air was way on top with perfoirmance...i heard top end screams with a cold air

Typically, CAI's and short rams both make power gains. CAI's make it in the midrange but generally show little gains on top end. Short rams lose a little low end but make gains on top. Long tubes of CAI = higher airflow velocities and strong torque, short tubes on short rams mean more airflow gets to the engine quicker at higher rpms. Just like our intake manifold.

Maybe we need a CAI/short ram combo that has a flapper valve that switches from the CAI to short ram at 5000 rpms.

My write up shows the spot to drill the hold for the intake.

Good luck, more pics

I really think if someone was to bother with all the work needed to do a true CAI on this car they should increase the piping diameter as well.

So warm air is better?

still going to be limited by the DBW TB size ...no?

your reading into it too much..

..no one is saying warm air is wanted over cold air... yet a short ram intake is better,..

..assuming ''better'' is describing a more linear powerband that holds/increases hp/tq all the way to redline with no drop off...

..where a ''cold air'' intake has a weaker powerband that drops off at high rpm's,.. and is not ''better''

..also,..throttle response vs pipe length is usually represented in a linear fashion with the longer the pipe the slower response,.. and the shorter the pipe the quicker the response..

but lets not crap on this guys thread and turn this into an ''intake'' thread,....

nice work cant wait to see some more pics,.. are you going into the fender with it?. what filter are you going to run,...I reccommend looking into R2C (cattman has them fs)

Well the TB is 76-77mm or 3"ID, and all the SRI/CAIs are 3 OD so you wouldn't be limited at all.

Very good workman ship, but I am a bit concerned with the calibration of your new maf assembly. The inner section surface of the maf is part of the equation that generates the signal to the ECU...

I would suggest a SAFC with a session on the dyno to recalibrate your air/fuel ratio correctly.

Looks proper man. I'm guessing your running a breather filter for the hose that used to be connected to the intake?

This guy is a G isn't trying to hate on either since he had both of them and respect his opinion cause he got the dough to try it all out! But me I love my Injen CAI and will get other parts soon so I dont drop off on the high end!
