56 RWHP Gain With Induction Change!

On my HK Racing 408 I had a LS6 intake manifold, Shaner Stg 2 OEM TB, descreened OEM Maf with Whisper ends, and a Whisper lid. I then bought a Fast 90 intake and spent about 6 hours porting and port matching it to my Absolute Speed 240cc 5.3L heads. A NW TB, Lingenfelter 100mm MAF, and Fast Toys lid were installed. Mike Norris did the tune, which I think needs to be dialed in a little more since my AFR from 6,000rpm+ is like 12.0/1. Mike's dyno which is conservative showed 524/501. I was delighted since this was through a 9", with heavy Dennys Nitrous steel DS, and Jet Hot 1 3/4 headers.

Outstanding power. Lots of area under the curve.

It was definitely way cooler in the after run. That being the case, it was still a significant gain. Mike Norris has probably tuned more cars in the state of Florida than anyone else. Dyno tricks? Most people I talk to bitch that his dyno is too conservative.

That is what is up. You just sold me on replacing my restriction. My 403 put down 463hp, 462tq and I have a nonported TB and a stock LS6. But, I do have an 85mm MAF and Fast Toys 85mm Lid.

I guess its a good comparison with the after results being in ~30 degree cooler air with uncorrected #'s.
Every dynosheet I see from there is either uncorrected or in the STD c/f. And I have yet to go to one shop who didn't tell me their dyno reads lower than normal, thats just a typical bs line to make you feel better about your #'s.
