I just bought a use maggy 112 kit and it came with a boost-a-pump from Kenne Bell. The question I have is this. Will this give me the fuel I need with a 3.2 pulley and the 43.5# injectors that come with the magnacharger unit? This setup will be going on an 03 ss with an lq9. I also have a ls9 cam that I am thinking about running with this setup.
So will the boost a pump keep up?
Kenne Bell say that it will give 50% more fuel to the injectors.

 

Can try it, but it would be better to get a good fuel pump that you dont have to overclock.

 

I would put a Walbro 255 in the tank.

 

I'm running one with good results. Pushing 75# injectors. Don't know about increasing the flow of your injectors 50% though.
