will i need a fuel pump and 24 lb injectors to run a 9psi powerdyne S/C? how bout aftermarket MAF will i need that too?

I would. The pressure to support 9#'s will be very high and you're going to be taxing the stock 19 lb'ers.
To be on the safe side I wouldn't go less then 30# inj and a Walbro GSS340 255lph high pressure fuel pump.

Yup. You're going to need to match the MAF meter to the injector.

^^^ What he said. The 24#'s will work, but the 30#'s are probably the best.

Ive got the Walbro 255. Good pump. Go with it.
