Your fdr depends on motor and size of track. The fdr you end up runnig is specific to you due to your driving style, again motor and size of track. Also depends on wheather you are using 64p or 48p gears. You just need to play with it and see what works for you.

So if I can acquire a 50t pinion, (88/50)2.4375=4.3 I can get to where I think I need to be. Also, I have looked at changing the upper pulleys to a 17t. That would change the tranny ratio to 2.29. This get closer to running more normal of gears.

No getting around it, the Cyclone is going to be difficult to gear with a 13.5. I predict that the next generation of Sedans will have a tranny ratio between 1.75-2.0

my cyclone is already using a 2.0 transmisstion ratio..
with a 5cell chassis.

What did you do? I know you've been posting some things you tried but last I could find you said the belts were a little loose. Do you have a final list of parts you are using to lower the internal drive ratio. Pulleys, belts, etc....

I went back and I read that you are using the 3Racing 18t Pulley, and some Schumacher belts. What did you use for the diff pulleys to get to a 2.0 tranny ratio? Thanks.

Looks like the prototype HB 18T pulley that was mentioned a few pages back.
