Whats the largest shot you can run with an upgraded inline fuel pump on the LS1's.

I will have to have a stand alone for my setup I am just wonderring where would the stock setup not be safe. I know a lot also depends on the octane level you are runnning but for k n g's lets say 93 octane.

 

Walbro 255 intank with Racetronix Hotwire Harness is supposed to provide 600-650hp worth of fuel.
Which inline pump are you referring to. MSD 2225......Aeromotive A1000?
