Zeeoh, the FRC tranny gear ratios are the same as the coupe and verts. I think redline in 5th for those trannys is well over 185. I had a '99 FRC with only a K&N air filter and Corsas and I backed out of it at and indicated 175. I'm not sure what was left, but it was still pulling.
Ooops -- your correct, I was using Z06 5th ratio instead of 0.74 for 5th. I used 3.42 rear end. Anyway, with the correct gear ratios, it says 182 MPH is at ~5950 RPMs.
BUT, this still does not explain how a stock LS1 with only an intake mod is making 360 RWHP (424 FWHP). BTW, it takes ~325 RWHP to go 175 MPH, so you can see there's a big required HP difference between 175 and 182 MPH (cubic function of speed).
Maybe he was loosing traction, and the rear tires where actually going 182 MPH, but the car wasn't. IMO, he really needed a GPS to get true speed in this case, because on a surface like that traction is a big problem! There is no other logical answer, unless he's fibbin' about his mods
