Hank, I don't have a print out of the NA engine, it was built by the machine shop owner that dynoed all of Tom's engines for his own personal use, and wasn't part of the testing that Tom did. But the torque for the turbo 250 peaked at 336@4200 RPM.
That's cool, 336 ft lbs is dang good for only 5 psi!
