Title: busa final drive ratio
Post by: borris on September 15, 2008, 08:47:42 PM

You guys that have running busa rails. What is your final drive ratio? I've only run mine a little but with a 4.4:1 final coupled to the 1.596:1 primary=7.02:1 it accels like a rocket with 27" tires @ 1200# and I don't need to run at redline. It's a little steep on takeoff tho. What is your experience??????

Yeah that's the busa final ratio but I was wondering what was commonly used as a final drive ratio for the busa cars that weigh 12-1500#'s.

with a 900lb car and 26" tyres we use the 14/60 or 4.3:1 ratio set. With 29" tyres its 13/60 which is 4.6:1
