451hp and 589tq at the wheels. 6 psi. The B+M blowers are 2 lobe teflon lined rotors. I replaced the seals and the coupling and shaft in the snout, the splines were beat. The 2 lobe rotors have more revision (they tend to chatter back and fourth, instead of just spinning in one direction) than the 3 lobe twisted 71 series rotors. I have close to 100,000 miles on this blower. I have driven this car to Carlisle Pa several times, 225 miles.
