the chain drive in the pics is as follows: 15 tooth, 46 link chain, 19 tooth; into a 500 ft lb, limited slip Quaife QBA2 differential. Once the heat issue was elliminated by the addition of a E-system scottoiler (for sale) and blower (can touch the cool chain immediately after a freeway drive), wear is minimal at best. Allthough after pulling a few wheelies, the chain must be replaced.
The original shift knob allows for 6 speed sequential shifting fwd and reverse with the dynojet quick shifter software. Weight of the car: 1400 with 163whp
A QBA11 will replace the chain drive.
