interesting thread. i just put a demon rr carb on a crate motor cobra and i have the butterflies adjusted all the way down and the idle is still too high. i am going to have to retard the timing i think. the front bowl is set just a smidge lower than the rear, although the carb is tilted down at the front cause of the rpm air gap manifold. the fuel pressure gauge says around 8 lbs off a mechanical pump, although i don't know if it is correct, prob just a relative thing. i haven't done any hard braking but did pull some pretty good g's on a round-a-bout intersection and didn't notice any idle drop which i did with a pro systems carb and a marine carb which would both drop idle on hard braking.
