Is there or are there problems with using Holleys with vacuum secondaries on a supercharged engine? I have a pair of small Holleys w/ vacuum secondaries for my small block chevy with a 6/71 supercharger. Will the blower draw too much vacuum on the secondaries to get engine to idle? Any help out there?
Should idle fine. The common Carter/Edelbrock AFB type carbs have an air valve in the secondary, it works kind of like the vac sec holleys. Also the linkage locks out the secondaries till you open the primaries Folks suggest boost referencing the power valve on Holleys...not sure if you really need to...but keep it in mind.
