Going DFI to carb w/ supercharger, Questions

I have fooled with this GEN VI DFI, and haven't seen any pros to fuel injection...nothing but a pain in the *** expensive and no power increases that i thought were worthwhile.

Question is, going from DFI w/ supercharger to carb w/ supercharger, what is needed exactly? I have found $500 blower carbs, and I'm not sure what exactly I need for a carbed s/c application? Anything I should be worried about detonation?

Please help? I'd like to run a race demon or a might demon if at all possible.

If you haven't already, you're probably better off asking over on the Power Adder forum.

About all I know about the topic is what I've read in magazines. Don't even spend time over on that forum on this Board. It just isn't where I'm going.

Sorry.

You need a blow through carburetor or you can get a regular douple pumper modified to work.You would also need a bonnet and ducting for the carb.

Issues for a blow-thru carb are:

Fuel floats can collapse,
Fuel pressure must be referenced to boost,
fuel bowl vents must be on the 'inside' of the carb hat,
throttle shafts can leak,
...
don't forget the ignition,
how are you retarding the spark, under boost?
