Could anyone tell me the final drive ratio for the Mugen MTX3 prospec with .8 gearing.

Thanks

I'll calculate it for you if you tell me the tooth count of each gear used. I don't have a manual.

the stock gearing for the prospec is 21/27 for the pinions. 53/59 for the spurs.

I don't have a calculator here..(not even the PC's)
but u get:

(Spur / Pinion) x (48 / 19)

JAG Racing

48 = rear diff gears & 19 = main rear shaft --- and then you 'll need the mid-shaft gear count and the front diff gear count if you want "over-drive" gearing ratios.

.. so it looks like the MTX-3 has an internal gear ratio of 2.53 ( or 0.396 ) depending how you define ratio - (mainshaft RPM/rear axle RPM)or (rear axle RPM/main shaft RPM)

Bandeira

rear diff : 49
main shaft drive to rear: 18
main shaft drive to front: 19
mid shaft driven: 24
mid shaft drive to oneway: 16
oneway: 32

This is quite messy... I keep only with the basic spur/pinion x 2.53...
and each 2~3mm in tyres equals one spur tooth...
