Years ago a friend bought a Pro Charger kit from the Supercharger Store. It included everything he needed to install the system (Carb, fuel pump, fuel lines, meth injection, Blower, pulleys etc).
He had a 360 that was factory except for the hydraulic camshaft, Weiland Xcellerator intake, headers and HEI ignition. The short lasted around 3 months.
He wasn't keeping an eye on the boost at all.
Only problem we had with installing the kit was the factory water pump pulley wouldn't clear the crank pulley. I had to make him a new billet pulley. I think also the blower crapped itself in the first week, which the Supercharger Store replaced no questions asked.
