Carl Foltz, pretty sure he doesn't use it either. He had heads on what 10 of the 16 car pro stock field last weekend? Like I said, I am 99.9% sure that Chad didn't use port energy as a consideration when he did that port, or any port on any head he offers. Neither does Darin Morgan, Slick Rick, Larry Meaux, Sonny Leanord, etc. Have they maybe calculated it once or twice on something they have done after seeing it? Maybe. Here is their response. "oh, that's neat". Haven't done it since. I understand the concept, I just think its filler for a program that isn't as good as 3 or 4 that already exist.
As far as Chads roadster, ok, he has 1 pass on it, can't judge it from that, I apologize. But, 2000lbs, which I am 99% sure it weights, + or - 100 lbs, with that power, should 60ft 1.15. It went 1.34, that was with wide open throttle. It should go mid 8's or faster. We will see.
I am not quite sure as to how many of the guys you mention the concept of port energy and energy density has filtered down to yet so it is hardly surprising they are possibly not using it.
David, I am not sure you have read this whole thread or not but if you get a chance page 3 and 4 have some graphs of Chad's 205cc heads vs. My Dart 247cc heads. I would be very interested in what your comments would be. You can post your comments or we can disscuss next call. Thanks, Charlie
