We had a dyno day on the 21st and I had to catch a plane to Chicago shortly after my run. I didn't get a chance to watch many of the other cars but here are my numbers:
'96 GTS baseline (factory stock) with 1,200 miles
414.0 max rwhp and 457.4 max rw torgue
Last week's dyno results after 6,800 miles and the following mods:
Hennessey carbon fiber airbox with K&N filters
SVP headers
3" high flow cats
Borla 3" cat back exhaust
Hennessey venom aero wing
Autoform splitter
436.2 max rwhp and 475.6 max rw torque
I did three pulls with nearly identical results. The air / fuel ratio was good ( between 13 and 14 through most of the rpm range). I was surprised and disappointed that I didn't get more increase from the mods, especially starting with a fairly strong car to begin with. I was expecting 450+ in the horsepower scale. Anyone out there care to venture why the numbers were low?
