Before people rag on the low original dyno numbers, please remember that ITR motors have never dyno'd very well when stock. It's entirely typical for ITR motors to dyno around 160.

Victor's completely stock '97 motor, on the very same day, dyno'd 162 hp.

I think there's a parasitic loss involved w/the Torsen axle's putting the power down to the dyno rollers, and it's really only appropriate to compare one ITR motor to another one.

Most of the information being presented in this thread could be entirely inappropriate if you're comparing w/a B motor dyno w/an open differential.
