Default anyone using TPIS cold air induction?

they also call this peice a "racing intake". i have just ordered this unit and was wondering if any of you guys have used this and wht were the track results. im searching for 12s on a L98 as stock as i can get it. right now ive done 13.20 with really nothing more than some exhaust work and DRs. TPIS claims 2 tenths and 2 mph with this mod. im confident that i could go 13.1x with a better launch, then im hoping the CAI will push me into the 12s. i know this peice will really only affect the 2nd half of the quarter, but this is where my TPI engine needs help anyway. the first 1/8 is explosive, but it falls of after that. thanks in advance

I run the SLP ram air; worth about 5hp over cut lid with K&N.

To pick up that .2sec, toss the "frisbee", install a 160deg stat and cut back the spark plug ground electrodes.

Stage as shallow as possible and launch as close to 1,500rpm as possible.

Thanks

A vigilante or pro-torque converter will put you into the 12's. Those are very strong numbers from a 89 car!!

I have it and am happy with it. I don't have any "before" 1/4 times, but just by looking at how it's installed, it appears that it does what it claims. I'd be interested to see what gains you get in the 1/4 after installing.

I too have been looking but want to see the before and after as its not that cheap :eek: but if it works as they say, it would be money well spent in my opinion. :yesnod:

Please keep us posted on your findings

:cheers:

:bb MY BAD :bb

I have the SLP, not the TPIS unit.

The TPIS is pretty expensive. If you haven't thought about it, the link below is for the SLP if you want to take a look.
