Default is one Walbro 255 hp enough pump for 450-500rwhp?

Looking at Walbros 255hp for my rig, is this enough pump or will it be maxxed out?
Is there another drop in fuel pump that's any better? Thanks

When I bought mine I remember reading they handle somewhere in the 700hp range...now whether that was crank or wheel, I'm not sure.

Here's the best deal available that I know of with all fittings included as a package deal to do the in-tank swap. http://www.texas-speed.com/shop/item...d=225&catid=10

How far did you have to dig to find an 8 year old thread?

Its probably pretty damn hot in WPHX today so maybe he wanted to cruise the net instead of working on the truck?
