I was wondering the actual distance of the front straight at Lime Rock Park in Ct, from the bottom of the downhill to turn 1?

Basically, I am trying to figure out if I will run out of revs by changing the gearing in my diff. I am 600-700RPMs shy of max in 4th gear. I'd like to use more of that power band down the front straight.

As an English major in college, I am open to any quick conversion calculators out there on the web, or the formula that I should use to determine the distance covered, while accelerating in a particular gear. I know wheel circumference, car weight, tranny gear ratio, diff ratio, and approximately how fast i am going at the bottom of the downhill. Am I missing any values?


Thanks.

Dave
