Jrama, you are the man!
Used the calculator for my set up in the YJ....... gives me 90 kph at 1800 rpm
Saved me hours and hours of work.
Was using my gps for speed and my factory tach for rpm and getting 90 kph at 2800 rpm..... (tach is a way out)
Was going to drop in 3.55 axles, now just have to chase down other reasons for low gas mileage.
Again, thanks for the post!
