I will be trying to mount a 49,50 or 51T pinion with a 90T spur, when those pinions arrive.
I tested the 48T pinion with 90T spur for about 7 - 8 minutes in my street and the motor still seemed to be cool.
I even did full throttle/break (continue repeating this) testing for about 2 minutes and the motor wasn't hot at all.
I especially did this testing for the gear mesh, if it wasn't propper then the spur would have been destroyed by doing that.
About the acceleration out of turns seems also to be better over a TT-01, that's my opinion. The drive train is much better and this gives the car in my opinion a better throttle respons.
Hope this helps
This helps a lot. Thank you. I have asked around and our local track regulars for stock touring are using tt01s geared 55-28. Straight is not as long as yours at 80m with 4 hairpins, a sweeper and 2 chicanes. Will the 90-48 combo be enough to go along with a 55-28?
I also understand that the internal gear ratio of tt01 and tt02 are the same at 2.6. Does this mean that I can also go 55-28 using the sanding method described a couple of posts earlier?
Sorry for the multitude of q's. New to TC gearing. Thanks in advance!
