My street car doesnít have near the grip as the track car and has a lot more understeer built into it, but the coroner speed in the race car is much higher and Iím in the gas much sooner. So I want the power to come in a bit slower and not hit like a sledge hammer.
Right now Iím leaning to the GTX2863 with a larger .82 a/r. Still need to get my motor back so I have a bit more time.
The GTX series will spool a little faster from what ppl say. and the 2863 is smaller then the 2871, so spool will be faster also. The GTX is overkill for what you need. the Gt2871r with a .82 housing will give you all the power you want with a nice spool up. Also your gonna have to use more throttle control to hold the spinning out of the corners.
