Zx5 + Novak 5.5 velocity running temps poss pinions???

[Colinevan]

Hello there.

I need some advice of running temps and pinion choices with a 5.5 velocity brushless in a zx5.

Iv played a little with gearing ranging from a 16 tooth pinion to 19 tooth which still result in a scorching speedo, iv cut the shell away to allow lots of cool air to circulate the fan and cut the rear away to allow easier flow out of the shell where the motor is.

My main tracks will be at Southport and Bury so any reccommendations on pinion sizes would be great.

Lastly, do any of you tone down the acceleration at all, or do you keep with the max acceleration and allow a little slip through the slipper clutch.

Thanks

Col.
