dr_hunt Posted November 5, 2005 Share Posted November 5, 2005 I seriously doubt they could be modified to work under boost. Quote Link to comment Share on other sites More sharing options...
SHO-Z Posted November 5, 2005 Share Posted November 5, 2005 Check Out this http://chevyhiperformance.com/techarticles/0411ch_huffin/ It is not on edelbrock but gives the basics Quote Link to comment Share on other sites More sharing options...
Turbo Meister Posted November 6, 2005 Share Posted November 6, 2005 does any one know if i can use the edelbrock carbs on a turbo setup (blow through) if so what changes need to be made. Paxton, many years ago, used the Carter AFB in an enclosed box for centrifugal supercharger applications. This worked well but was limited to 6-8 psi boost(I think). The Edelbrock carb is like the Carter and only has 1 fuel inlet for both primaries and secondaries. This limits fuel flow as compared to a Holley dual inlet carb. If you kept the boost low, jetted up, used solid floats and enclosed the carb in a box like my Z, it would work. Hanns Quote Link to comment Share on other sites More sharing options...
BrandonsZ Posted November 7, 2005 Share Posted November 7, 2005 Edelbrock has special carbs for supercharged application, they could work for turbo. Quote Link to comment Share on other sites More sharing options...
shortbed454 Posted November 11, 2005 Author Share Posted November 11, 2005 would i have to run a box or could i get away with a carb hat. Quote Link to comment Share on other sites More sharing options...
dr_hunt Posted November 11, 2005 Share Posted November 11, 2005 I think the supercharged carbs are modified for high vacuum. Blow through would be a different scenario. I'm not sure exactly what the metering changes are, but you are right, you have to use nitrophyl floats. Quote Link to comment Share on other sites More sharing options...

BirdmanZ Posted November 18, 2005 Share Posted November 18, 2005 the key to running a blow through setup is using a boost referencing fuel pressure regulator. otherwise the incoming boost pressure will keep fuel from entering the bowls Quote Link to comment Share on other sites More sharing options...

I mean the fuel pump pressure regulator may be set and say and you are running 12psi boost and you try to go higher you are lowering the volume flow rate into the cylindar even though the injector may be opening longer.
