Cast alum. rear bearing plate, billet front bearing plate, and cast front gear cover offer maximum strength and gives a superior polish. Injectors with a 13.250" on center bolt pattern can bolt to the top of the blower as well as 4150/4500 carburetor adapters.
Top opening on the blower case is 12.875" x 4.125" and the bottom opening is what is know as a retro bottom giving the blower a more efficient way for the air to be pumped into the motor but is must be set back on the blower manifold to seal. Front cover has a pressure relief installed.
Rotors have strips of Teflon added to the sides, nylatron installed into the tips of the rotors to seal the rotors to one another and the case so once boost is put into the intake the side Teflon strips stop the air from trying to leak back up thru the supercharger keeping the boost down in the intake and more power being made. Recommended for alcohol or nitro use only.
