The IMRC creates that early torque spike by the low speed, high density air from on using just the short runners. (i.e. restriction) It's also why the stock engine falls flat on it's face at 3000rpm if they don't open.

My first dyno showed 168 FWTQ below IMRC and 164 FWTQ above IMRC. (not stock of course) The only real powerband is above the IMRC so the other higher peak value was really just a pointless number.

2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
