I'm sure the KB boost a pump will work fine if you strap a blower on the stock motor. But if your building the engine down the road you should go with GT500 dual fuel pump which was designed for 500hp+ cars as opposed to increasing the voltage on the stock gt pump. Or go with a returnless fuel system if you plan on making really big power. Sounds like a fun project.

You mean go with a RETURN style for big power right?

And I have a FRPP GT500 twin pump kit for sale if you are interested. I personally don't believe in boost a pumps but know many people that run them without issue.

Sorry I did mean return style, though either could work. The return style is superior, I've heard the returnless one's have fuel delivery lag and timing issues. What fuel system are you feeding your procharger with?

division X 1200hp return style system with ID 1000 injectors

Nice setup, lots of room to grow with that system.

I have been using the Kenne Bell boosta pump, with no issues.
Car is @435 at the wheels. Which is about all you want without doing the bottom end.
