Would a fresh Stage 2 need more jet than a tired Stage 1? All else being equal...... I'm running 96s in my 1050 which is what my old Stage 1 liked. The fresh Stage 2 seems to want less jet. More efficient? What jets are others running at the strip on Stage 2 setups w/dominators? thanks Bruce
Hey Bruce, When running my car on gas I tried to keep the jetting around 92s. At Norwalk this year we put my car on the chassis dyno. It showed that even at 92s it was running on the fat side. So we dropped down to 90s and the car picked up a bit. So... I am gonna say anywhere from 90 to 92 should work. Good Luck
Thanks.... Any problem with running the primaries 2 numbers smaller to keep it clean on the street and starting line? Or would the distribution be a little off? Ever try that on the dyno? Bruce
Bruce, A dominator doesn't have primaries and secondaries. The best way to look at a dominator is to invision the carb as being two carbs in one body. There is the front half and the back half. When tuning a dominator make sure the idle circuits are equal. What I am saying here is to look at the idle screws and make sure both front and back are holding open the butterflies in the carb equal amounts. Also make sure the transfer slot are not uncovered. If you are still having problems on the street then you may have to put larger air bleeds in the top of the carb. Good Luck
welp.. I would go 92 square. Remember, every number change in a Holley jet doesn't mean the orifice size hole changed, just because the *number* changed... J
I know John but I drive on the primaries on the street with my 9375 with it's progressive throttle. I did drill the air bleeds and it made a big difference in smoothness on the street but then hesitated at the track whick I solved with bigger squirters. I was just wondering if the distribution at WOT would be adversely affected by not being square.....but most carbs are run that way and maybe it straightens out in the manifold. Bruce
