x6 Gearing?

[Hulk]

Hi,

I finished building my X6 last weekend ready for the Petit Invitational.

I know people us a smaller spur than the Kit B4 one.

Ive put on a 75t spur for now.

Im running a Speed Passion 6.5. Any idea what pinion i should use as a starting point?

Thanks

Is that on a 75 spur with a 6.5 motor?

Thanks

78 spur and a hacker 6.5 motor, used to run a x11 12.5mm in it prior on same ratio

i ran a 24 / 81, dont know what the overall ratio is but if you work it out it will give you an idea of where abouts you need to be.

23/78 on a 6.5 all last season for me

You need to run a smaller spur as the 81 clips the driveshaft pin
