Half Fast
Touchdown! Greaser!
I did, I was more willing to let it go to or past 8k. I’m not sure if that contributed to better lap times, at least not significantly. The bigger thing was not upsetting the car mid-turn with a gear change.
I'm sure it helped. When you can use a lower gear in a turn and get better acceleration exiting, you'll carry that all the way down the straight.
Watch your temps and move your rev limit up until you see the temps getting too high, then back off a bit. I think you'll find you can use 9000 or so as a redline when the air temp isn't extremely hot, and even higher once or twice a lap if you need it to avoid a shift. You should have better cooling now with that larger radiator.
