This is mostly correct aside from one consideration.

You must keep in mind that TT cars are able to take the same fuel system noticable further. The supercharger systems use a lot of the HP they generate, so a larger fuel system is required to generate the same power to the wheels.

The GTM SC kit uses a supercharger that is supposed to be much more efficient in its losses, so I would expect that GTM will be able to take the same fuel system configuation slightly further than the Stillen/Vortech.



To the OP: Your WHP doesnt sound too far off from where I would expect those injectors to max out with that type of SC, but that depends greatly on the type of the dyno you are measuring on. If you are on a dynojet, I think you should be able to get a little further if your injectors are actually that size.

I will have to look into what Stillen does to the fuel system for their kit to give you better information.
