Im going to spray a 100 wet shot, and already have the 224/224 cam with roughly 400hp. Only upgrades to the fuel system is some 30lb svo injectors. I know I will need a pump, but which one? I can get a really good deal on the walbro 255, but I just want to make sure its enough. Will I need bigger injectors? Or anything else?

 

Injectors have nothing to do with wet shots.

Yes, the Walbro 255L intank pump is all you need. I would recommend a hotwire kit and new filter though.

 

A good fuel pump or a stand alone fuel system would be plenty....and your gonna need good tires if you plan on spraying out of the hole.

 

I have the same question about a dry kit. I have 42# injectors. Do I need a pump too? I will be spraying 125 shot.
