belts: cutting every OTHER tooth???
hey
i was just wondering... ive heard a lot about cutting off every OTHER tooth on belts for belt drive cars, to make the drivetrain more free.....
does every OTHER tooth mean every SECOND??? like cut one-leave one-cut one-leave one etc..
and could somebody please explain the best and easiest way to do this without damaging anything?
and also, is it really worth it??? does it make THAT much of a difference???
im running xray btw
let me know,
thanx, robbie

That is what I did with my LOSI car. Since the X-Ray belts are much more narrow I wouldn't think you would want to cut out teeth. From what I have seen, the X-Ray drive like is very free to begin with.

you should try cut the front diff pulley tooth.......
check out the pics from josh cyrul's car and you'll see how it's made....
and surely works...josh was toooooooooooo faster at the roar nats....

I just cut the belt on the Losi I built. Found easiest way was to turn the belt inside out and use fingernail clippers to clip off every other tooth.

I do it on my Losi belts, but really dont see a need to do it on an XRay belt because like everyone is saying, they are already free. I have heard of Josh cutting teeth off the gear which I would think is a better idea on that car since the pulleys are pretty small, cutting teeth would propably make it skip easilly.

Doesn't removing teeth on the belt cause chance of stripping the belt? I don't think the belt could handle a mod motor and it would strip and end your race. My Xray drivetrain is very free, mostly with high speed bearings and the 1.77 internal gear ratio. I would like to hear from Josh or other factory team pilots that have done this on their opinion.

I was under the impression that this was done to the Losi Belt because it is a single belt system that has to loop back on its self so cutting out the extra teeth added more flex, making it easier to loop back. Im not even sure this would benifit any other cars..

There is no more chance of stripping the belt from when it was stock as long as you dont cut into the fibers. I havent seen anyone strip a belt out here weather it's cut or not...

I bet he said that the car was crap, not that what he've been doing was stupid...

i have cut every other tooth on my xray front and rear belt on the evo2 kit it was noticable with stock but should not be done with the rear belt it will strip to easy i ran the front cut belt for at least 3 months i replaced it when it was tweeked or bent side ways and flipped over twice in one day but it never broke running 19 turn
for stock it is noticable and worth cutting the front belt but i would not do it with 19t or mod and i would cut the pully this time
alex lopez runs super thin belts front and back that were saved down to kevlar and were super flexable when i spun his drive train you could see how free it was and no one can say he is slow
but when he put a 19t he broke it
