Let me snip the best part of Randall's reply:
<< ...Maybe we ought to find a dyno and test it >>
Great idea Randall, that IS a cailbration, can I assume then, that the car
doesn't have a torsen center diff?  Might not be so easy to do this
calibration tho, hard to take advantage of all that IC efficiency.   I think
we need to figure how one gets 513CFM into a 134ci motor first. 2.79PR from a
2.50PT computer might be next.  Thanks for the reply.  Anyone else?
