[QUOTE=coopsnard;9930050]yea im running a 10.5. and im runing the 81 tooth spur with a 21 tooth pinion. I think thats ok right?
i would go up a few teeth on the pinion, i run a 81spur, 21pinion on a 7.5 motor in my b4.0 lol. start with a 24t pinion, and go up from there! u might end up with a 26-27t pinon with zero to little timing.

Go to 81/24, and there's no reason you should need a fan with a 10.5. Guys run 7.5's all the time with no fan. They don't run them for 30 min. at a time though.

Ive attached the photo of my Kinetic setup in my B4.1 (before the +8mm conversion).
For the guys asking about whether the +8mm chassis is worth it - do it! Especially if the track is not super smooth or has jumps that arent perfectly manicured. Makes the car much more forgiving. Here is a photo from a big race 2 weeks ago I won in Melbourne using the new chassis. Thsi track was really bumpy with some huge jumps and around there it was a massive improvement! Setup sheet here if anyone interested:
