300 Cfm heads Horsepower

This is a bracket car that I run all summer. Not sure why im leaving the impression I ran it once ever and I have no idea what im talking about? The et calculator I use shows it should run 10.30's. Not sure where you are getting mid 9s. Yes its a foot brake car, so im leaving some on the table. Do you think im saying 610 wheel? No. 600 CRANK on an engine dyno. Maybe that's where the confusion is coming in? Sorry if it thats what I implied.

However we should all digress entierly as this thread has absolutely nothing to do with my bracket car. Sorry if it was taken as wheel hp, and if it wasn't, then sorry apparently my car is such a slow pile. Lol
Just wanted the op to have my example of 290cfm making 600 ish crank hp in my build.
