On a stock internal, I wouldnt go more than a 150 shot, seen my buddy mess his up, and his dyno told him not to, the power just wasnt there cuz of lacking fuel. Personally, I spray 100 and the car seems to love it, have sprayed 150 and no problem, but if your not stock internal careful cuz your pushing it. Goo-Luck.

460rwhp w/ stock intank pump and 30lb injectors. I know at about the limit of the pump, so a Walbro 255lph is going in.

My car made 606/687 with the stock intake pump and on pump gas (73/38 jets NX kit) <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> The car only had an NOS inline pump and nothing more.
The fuel pressure never dropped and the A/F was between 12.0-11.0 the entire time....
This was on the stock bottom end also. I would not recommend this however because the car did lift the heads on the way home that night <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
