I have been interested in the blow through type supercharger from Pro-charger. I currently run a 383sbc making about 475hp 455tq. Curios as to where the extra fuel comes in under boost. I run a holley 750HP, do I need to fatten the jets?
Will this create a driveability problem while under low boost or cruising and idleing speeds? Or is this similer to NOS in which I need to add a seperate fuel system

I dont know all the mods done to a BT carb but I do know that most of the extra fuel needed under boost comes from the PVCR's being open up do feed more fuel.
Like forcd02 said you need a boost reference reg with a good pump .
