What Diff are you running in it?

I believe it is a Sierra diesel diff with slipper 3.14 ratio. Why do you ask?

Trying to get some idea what the gearing is like on Knockhill, mine is being built with a 3.38:1 just now. Standard Busa engine.

I do have a 3.14 laying in the garage and plan on fitting a Quaife ATB diff, I havent decided if I will put it in the 3.38 unit or the 3.14.

I was thinking of a 3.14 open diff for the road if I was doing any touring and the 3.38 LSD for track and fast road stuff, just don't want to run out of Revs on the track.

Whats the tyre size your running as that will make a difference also for rolling circumference.

With Knockhill being my nearest track I will be trying to best suit that.
