Doug,
Sorry for the delayed response, I'm at work right now.

I'll post my set up for Lime Rock later on after I get home. I believe I changed the final drive, then jockey'd the 3rd & 4th gear ratio's which gives me a different final ratio solution in third.

I'm just about topped out of third at the exit of the right hander leading onto No-Name.

When I drive the track for real in my 1600 car, I always know how successful a lap is based on how soon I run out of 3rd after that turn
