TAV2 best ratio

[Ferrari motors15]

My motor runs at 3600 rpm. It's a 6.5 hp.

I want to buy a torque-a-verter2 from comet.

I would want more torque and speed. I'm doing off road and krushstone.

I would like to know the best ration between the axle and the driver.

i got 22 inch tires ... runnin a 6:1 gear ratio with a comet 40 series and 10hp motor. at 3600 rpm it will top out at about 32 mph. My kart including myself on it weighs about 400 pounds and hauls arse. Lots of low end torque. Could regear a lil higher for more top end.

Top end will be the same though .... 6.5 will only get you there a lil slower
