This part is a machined piece of art that will improve the performance and horsepower on your race car with a simple bolt on that has no affect to your original screw blower. The top plate starts out as a .500" plate of billet aluminum that is machined down and scalloped to save weight yet offer a sturdy mounting platform for the blower insert.
Now for the magic part of the insert. The insert starts out as a seven pound chuck of billet alum. that is CNC machined to fit down next to the rotors and allow the blower to become more efficient due to the air being diverted more to the front of the blower then passing past the insert which has been machined to run fuel out of the six small holes you see in picture one allowing for better rotor sealing, cooler incoming air charge and this all means more boost which equals more horsepower which provides lower E.T.'s.
Included are five SFI blower restraint straps that customer can specify length when ordering. Complete unit in the picture weights close to ten pounds.
Customer must specify strap length, C or D rotor screw compressor and if the blower has been cut down .400 on the top of the blower.
Grade eight mounting hardware is included and all alum. parts have been black anodized to prevent corrosion protection and to offer stealth appearance. Testing has shown 1.5 to 2 pounds of boost increase.
