Just wanted to know how many of you supercharged guys are drawthrough carb, blowthrough carb, or injection. Any comments about how easy it was to set up the carbs or program the ECM?

Carb. Do not like ECM!!

holley carb. Nickerson set up the carb when he dynoed the motor.

MPI is the only way to go!

Ran carbs for cost reasons mainly. Easier to tune and maintain without special high $$$$ equipment. Set up is mine and just start rich on the mixture and work your way down slowly. In my case I will gladly give up some HP rather than chance running lean.

I would rather carb. EFI takes more $$ to set up properly, which most people do not.

With carbs I have some idea where to look when things go wrong. With injection you need to be able to analyze the ECM, which is getting way over my head.

Both, eight injectors in the rails, eight more in the hat...

I have done them all. Fuel injection is terrific if you set it up right. But that requires programming the ECU. Delphi units like Mercruiser must be sent to someone who can reprogram them and that is expensive and time consuming. Then, if you change anything, you start over.
Carbs for draw thru are simple, easy to work on and easy and cheap to fix. Just index the power valves!!
Carbs blow thru are more difficult to set up initially but work great and are still just carbs.

I have done both. I never hurt a carb motor... ever. EFI motors, lost two in one year!! Fuel starvation is readily apparent in a carb, but stay hidden in EFI... can lean out one cylinder & frie the piston...been there, done that.
The EFI is more efficient, more costly, instant starts, sooty transom.
Nickerson carb..efficient, less expensive, instant starts, no soot!!
Carb' with blowers get my vote.
