what pinion would u use on a 8.5 novak

As a rule of thumb... 2-3 teeth less than the brushed equivalent... then check motor/speedo temps...

I think the 8.5 BL is around the same as 12-13 turn brushed...
Make the Final drive ratio to somewhere about 6.5-7.5 FDR... To do this divide the spur teeth by the pinion teeth i.e. Question: How do I figure out my final drive ratio (FDR)? Answer: Divide the smaller gear (pinion) into the mating gear (spur). Example: 108(spur) ÷ 24(pinion) = 4.5:1 (FDR) If your car has a gearbox you need to know the gearbox reduction ratio. We'll use the Associated B2 ratio of 2.400:1 for an example. Divide the pinion into the spur then multiply by the gearbox ratio. Example: 85T (spur) ÷ 16T (pinion) = 5.3125 x 2.4 (gearbox) = 12.75 or 12.75:1(FDR) What this means is that the motor makes 12.75 revolutions to every one revolution of the tire. WHAT CAR U RUNNING...?

talk about over complicate something!
and that ratio in a micro is nuts! Richard, simple answer, the smallest pinion you can get, a 10 tooth, and the biggest spur, a 49t. But to be honest, the 8.5 is a bit loony for racing in a micro, especially at Wycombe. Turn down your throttle end point if you can!

I agree with Jim, the 8.5 is seriously quick but start with 10/49 and see what your temps are like after a run.
By the way Jim, where have you been hiding, haven't seen you at Wycombe for a few weeks? Richard |

If your running an LRP Shark or FT Blaze with Touring car wheels on it then....
I run at 11/49, 10/49 would be safer. they are right, it is nuts fast for micro racing, but I like lit
