Since you are dealing with ratios you can just change both gears and maintain the same ratio while moving the motor up.
example: you run 93/28 which equals 3.32 ratio
if you switched to 90/27 your ratio would be 3.33 so it wouldnt change much at all but your motor would be higher.

I was running 93/28 for a while and the motor can was getting scratched on the track surface. After I started tuning my motors they were getting too hot with this ratio so I geared down a little. Now I run more like 93/26 and it is perfect because it is super low but not dragging which is ideal.

Are you running the T1R/T1 Evo bulkheads...or the T1 Factory Kit bulkheads?

I am running a T1R. I guess the same question for my bros car too. But he has an FK. So a T1R and FK.

Hi guys, i was wondering if it was ok to grind/sand down the teeth on the front diff pulley for stock racing

Chazz- there is really no need too. The drivetrain is so free already. You can set all your bulkheads on the loosest setttings for stock racing. I have found that it is the best for me so far. Its very light on the drivetrain and is effective. So just change the notchs on the bulkheads toward the loose settings.

It's okay to do it. It frees up more the already free drivetrain. I've done it will all of my front components (diff, oneway, spool). Just don't do it for the rear diff.

So you just gring it bold so it's nice and smooth

Neil Rabara

Pretty much I dremel away every other tooth on the front pulley. Don't touch the layshaft pulleys or the rear pulley.

Ok, well here is the mistake alot of people make. With the regular bulkheads (not FK), there is actually no way to run front anti-dive. It is either 0* or 3* of kickup. For carpet, you will generally want 0*.

On the other hand, your brother has the FK bulkheads, so he can run anti-dive (3* max...I think). Same thing goes for him. Try out 0* and if he feels like playing around with it, 3* of anti-dive would probably be the next best thing.

Either way, I like 0* though. That is what I almost always run on carpet.

Thanks Kevin for clearing things up. I will switch back to 0 kick up and i will let my bro know which ever one he wants. Thanks

after switchin back to 0 kickup instead of 0. I noticed a droop and ride height change. Doesnt sound normal to me, but i was wondering what people droops are for stock carpet racing.

I have mine at 0mm (front) and 1mm(Rear) And as for ride height i just left it at 4.5 and 5. (I have asked this question before, but only one response and it was 8mm. Sounds alittle Hight) Thanks for the help.

the ride height and droop will change because the angle of the arms has changed.

i run 2mm droop front and rear from the lowest point on the plastic c hubs(not the screw on the front) and it works well everwhere for foams,
