Injector size?

[olesneakypete12]

I have a 347 stroker...10:1 compression...I am about to put a vortech v1 S trim supercharger on the car...The guy threw in a set of 24 pound injectors with a mass air meter for the car...Will it be safe to use these if i put out only 6 pounds of boost? Whats the worst thing that could happen if i need to go bigger in size? My block is stock...im kinda worried but willing to take the chance.....Also, for now will it be a big deal that my fuel pump is stock? I never got around to changing it yet....????????

I'd definately suggest getting a bigger fuel pump. The 24's would be fine for the 347 NA but when you start throwing boost at it you will want more fuel otherwise you could lean out the system. Sell the 24's and MAF on forums/ebay and use that money to get the properly sized injectors for your setup.

Fuel pump and injectors need to go for sure, if you are thinking of adding boost.

I also would hate to see the block crack

Sounds like you need to make a few series of upgrades, good luck!

put in 42's or something bigger than 24's

With 42lb injectors, you do not need a fuel management unit.

i would step up the injectors you need bigger than 24's forsure!
