Gear ratio calculator Mon, 26 September 2005 12:43 Go to next message

Hi guys,
Been fiddling with this gear ratio calculator as my current gearing setup means that I have to change into OD with about 50m or so left before the end of the drag strip. I have put in my current figures but the calculator is slightly higher than what I have experienced.

The only thing I can think of that could effect it would be the big head wind on the day of racing and also that Willowbank is infact slightly uphill.

Anyone, whack in your details and tell me if it is correct.

If you need to know what diameter your tyres are use

Thanks
Chris

I just ran my numbers through the link Chris and mine come pretty close to what I run on the track, very close actually.

It also indicates that when my new tyres arrive it should be spot on for crossing the line only a few rpm before redline in 4th Smile
