Ok, the numbers are in. They did 3 pulls on their dyno and ended up only charging me $125 for their efforts. As it turns out, the A/F ratio was near ideal and it put out significantly more power than I expected.
It spun out 382.8 HP at 4580 RPM & 525 ft lbs of torque at 3541 rpm. They said I'm losing about 20% through the driveline. Using that number, the corrected flywheel HP should be 478.5 and the torque should be 656.25 ft lbs.
This was better than I expected given the results of the roller dyno run of a year ago.
