Just got back from Dez Racing. We are going to do some fine tuning on the Holley HP for the fall racing season. Before we did any tuning we did a dyno run to see what the difference was with the bigger headers I put on in July. We went from 1 5/8 SW to 2 in. custom. When we saw a increase of 49 RWHP (641-690) we were surprised.

The enterance front office always looks like a Fd Ex warehouse.

With the larger pipes was there much loss at lower end ?
