Fast Intention question

g37hr

I've been trying to figure out hp gain with the fi rhfc, I just bought some. Anyone have an idea ? Thnx

My case, I took my car to the dyno (DynoJet) with just the Stillen Gen 3 CAI and stock exhaust and got 295whp. When I got Fast Intentions non res HFC with 12" res CBE on the same dyno, I got 322whp with Uprev tune.

That's very nice. I'm on the FI waiting list between April - May time frame. I also have a Stillen G3 CAI on the way next Monday. I went with the FI CBE 18" res and FI non res HFC.

Just out of curiosity how do you like the sound on your setup. Too loud or quiet, any rasp? What WHP did you get before the uprev tune?


Thanks

For me personally the louder the better, but I'm happy with my set-up. When you floor it you'll hear it trust me, but cruising on highway you barely hear it. In my case I have no tin can rasp, just a nice deep growl. I didn't do a baseline on whp, but like I said, with just the Stillen CAI and stock exhaust without a tune I got 295whp, so I'm guessing my car all stock would have been in the 280-270 high whp.

Went with test pipes and 18" resonators with 100 cell hfc integrated to the Y pipes and it put a smile on my face every time. Amazing sound.
