The way I designed the blower mount, it could be easily adapted to most any reverse rotation supercharger with a simple change of the top plate and setting the spacer depth accordingly. It has many advantages over conventional mounts such as minimized belt length (and whip), a tensioner on the slack side of the belt, and 50mm belt width. It also minimizes side loading of the crank due to the fact that the cog is as close to the timing cover as possible (over-wrapping the balancer).
The plates were cut at a local waterjet job shop. The packaging was optimized for my west coast cobra / stallion application. I don't know if it will fit other applications.
Take a look at it, and if this is what you're after...drop me a line using www.racesystems.com and the contact button. If you're doing something custom, it would save you a lot of time having at least the engine geometry already mapped out in a cad program.
