Post Re: Speed versus RPM calculator
Yeah I need one. I am just being cheap. I still need a temp gauge for the LC kit, but I know I want a tach too. But I dont want to spend $180 on the S6 do all and I havent seen a resonable alternative.

Nice Calculator! I got 50.8 MPH on the GPS turning 10,040 RPM and the calculator says 49.8 MPH so I'd say it's pretty damn accurate.
Thanks!
