Well, get us all excited will ya!

Last time I had my Challenger to the track it ran a best of 13.9 @ 100 with an old stock 1968 375 horse 440 with headers and a 750 Holley.

I wonder what I'll pick up with a few PSI thrown at it?





Rule of thumb is approx 30 hp per boost pound.



Is that for centrifugals as well? I'm getting 12 psi intercooled, does that really equate to 360 hp? seems high to me.
