Desktop Dyno pros in here
Hey guys,
Trying to run through some preliminary 351W #s using DD2000. What I'm noticing is that going from stock heads to ported stock heads to GT40P heads is showing almost zero difference in DD2000. I've used a CR of 9.5:1, about where I figure I want to be, and a Comp XE274 cam which is what I was thinking of using. I just expected that with that cam, and well-breathing intakes, that I would see a greater improvement in going to better heads. I'm wondering if some of you pros could check over my files/setup and make sure everything looks correct...
Here's my saved workspace file (right click and do a saveas)
That has a 9.5 CR, and XE274 cam, but with stock heads.
Here are my flow files for the other heads I've tried. None seem to show much difference.... any ideas?
Thx for the help.
Edit: BTW, I got the head flow #s from here ... do they seem reasonable? |
