I run mine a 6 lbs. low pressure and plenty of volume is what is needed on a Q Jet. one gallon in 30 seconds is about the minimum you can get away with.

Thanks guys, so it looks like I'll have to lower the fuel pressure when we can get to the track the next time. Now I was running with 7 lbs pressure, so it's interesting to see if that could fix the bog when launching.
