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.


Bob,What's the rule of thumb with a roots blower??



i think it is more like 40hp per lb but also think it has to do with size of engine and head flow combined.
