Turbo gearing help?
« on: July 25, 2018, 11:39:29 AM »
Beating the dead horse I’m sure. But my turboed 08 is street driven. Weekend drag strip. 66.5” I think which I might change a lil bit with the new arm. But 19 up front, 52 on the rear I’m crossing the 1/4 at the top of 4th. I was just told it’s like a 2.75 overall gearing which is super high in the 1/4 mile?? He was surprised I’m not crossing in 6th gear lol so at 256hp and 205lbs what would you guys run? Opinions welcome. Launching is still in the works. But here’s a vid https://youtu.be/JPnDasPvOBE

My bike is around 19/46 and it crosses in 6th. Slightly more HP though.
Any day on a motorcycle like this that ends just needing parts and labor is a good day.

With 300 hp at 63.5" no boost control and stock clutch I used 18/45. 5.3 1/8 and 8.5 1/4. Worked well on the street also. 1.41-1.45 60'
