If he has the BMW rear end which I think the Venom has, unless it was ordered with posi-option I believe turning the tires one round and counting driveshaft rpm's will not work on open diffs. Most the BMW drivelines came with 3.15 gears pretty high geared my opinion. Mine had similar numbers as JP's when mine was geared with the 3.23 posi optioned gears upon delivery, darn thing would run 100mph in second at 7000 rpm. I have put 3.73 in a while back, completely different animal. Never have hit rev-limiter in fifth gear yet, pretty scary, but fourth gear at rev-limiter (7500) she does 135 mph, still pulling hard when she touches limiter quite exhilerating.
