I'm sitting here watching the NHRA Drags on T.V. and I again noticed something that I been curious about for years .....So.....I know someone here has the answer....."What is the purpose of the Set Back Blowers on the Fuel cars??"

Naw, crew chiefs found (I think it was Austin Coil playing around on his blower dyno) that the setback allowed the rotors to pack the cylinders better and more evenly and at higher velocity.

My B&M doesn't have that problem due to the straight rotor design.

It will also NEVER make 3 - 8000 HP !
