Like I said,it ran fine for about 20-30 passes and then one day it started lean popping and ended up at 93s.Whatever the case it runs fine now.Fuel pressure and all seems to be fine.Got a gauge on the main line of the pump,before the regulator,that I can watch thru the windshield.Just idling it runs13-14 psi and going thru the lights it usually sits at 12-13 psi.I try to keep all my stuff good and clean.I clean out my filters regularly and have just recently blew out the bleeds on the Dominator.My real question was about the 177 blower,but I talked to a "tech" at Weiand today and he said "no way,that blower will never do anything for 500 cubic inches"Oh,well.
