Like Mike said, 480 rwhp is pushing it. However....
There is a 98 Ws6 running around here with a big LPE motor making rougly 510 rwhp on a stock fuel system. Still gets good pressure and a/f is about 13:1. The fuel system itself has about 75K miles on it FWIW....

I've got the Racetronix in-tank plug-n-play pump (255 L) a SVO 30# injectors. 525 rwhp NA.
The Racetronix setup is available thru www.Agostino-Racing.com

Racetronix has started to ship the 1999 & up LS1 f-body fuel pump upgrade harnesses as well as some special Walbro fuel pumps.
The fuel pump for the '99+ f-body with the venturi outlet is being beta tested right now by one of our dealers and a soon as we get a thumbs up we will start production on the pump. You can order the fuel pump without the venturi outlet right now but that would require disabling the scavenging function of the factory fill bucket by removing the check-valve in the bottom.
Racetronix kits are available through Agostino, More Performance and other dealers. Racetronix sells direct as well however we encourage customers to buy through our dealers for support. Especially dealers that sponsor boards like this one.
Please note that the C5 HP pumps and wiring harnesses have been available for a couple months now.
