I'm running the stock 4.083 again with 255/40/17's on 17x9's. That might be part of the lower results. The first time I ran was with the 4.363 and 225/50/16's on 16x8's. I know gearing shouldn't be playing a part in the measurement, but we did one test that showed otherwise. We did a 5th gear partial pull at 1 bar to show the difference in spool-up on the dyno (versus 4th gear). It was indeed earlier, but the overall torque was notably less. If theory holds true, it should have been the same.

No track events yet. I'm going to take another crack at sealing these oil leaks. Then I might to a TR track day or something. I'm getting new sus soon so I'll wait until that's squared away to try a HPDE at Sebring.
