Beautiful work. If the car looks half as good as the motor, it will be stunning!
What are specs for motor? Did you dyno it, and if so what is HP/tq? What made you choose centrifugal SC over other types?
Good luck, and keep up progress pics!
If you turned the manifold around 180 degrees you could have a real short pipe from supercharger to manifold ... if nothing else less weight. But I guess you might want to run an intercooler later?
