ever degree dropped in intake air should be worth 1HP or about a 10% gain. The blower takes power to turn so its kind of a trade off. You could increase boost with the intercooler safely. Speed gain would depend on changes made to overdrive and timing.
Im thinking a extra 2-4 mph depending on which changes were made. |
You can't put 6-8 #'s of boost to a 496. The pistons won't last.

I thought the 425 h.p. 496 (mag) had forged internals and 375 h.p. did not???
|
He didn't ask if the engines would last. :evilb:
