NA just fine... however, it's overkill unless you plan on running E85. otherwise, you really don't need a top feed setup. if you are still looking into a top feed setup both the BDE and my WINFactory rails use the Injector Dynamics injectors which start at 725cc of flow (which is easily tunable for NA application).
Best run: 1.60 60', 11.319 @ 120.65 mph - 118 octane fuel (on 100 octane tune), 22 degrees of timing, 21-22 psi boost, 11 psi tire pressure (street slicks). "..know your car better... RACE IT!.. AS OFTEN AS POSSIBLE.." "Drag racing is for fast cars... Autocross is for fast drivers... Drifting is for cheap tires..." I made up the last one..
