So... are we saying that its about 300WHP? What would you have to do to get my goal of 400hp for the fuel system?

Most likely with boost from what I hear it can be kinda hard to get those numbers without it, but either way the fuel system still needs to be there.

Unless the TS has subliminal messages I'm not getting...

It was a simple question about stock capabilities, and people come in talkin about pumps, injectors, MAFs... It just makes me laugh sometimes..

lol I am just adding some real world information, not trying to mislead anyone. but from what I know about the stock returnless fuel system, you can't run any more than the stock horsepower without changing/modifying something if you want to get technical about it!

my buddy made 380rwhp with a hellion 62mm turbo kit, focus pump, 42# injectors, lightning mass air meter, and a custom tune on his 02 GT.

You have to change the fuel pump and the injectors.

I did some research on the fuel pumps, FWIW the '03 and '04 s/c Cobras (390 HP at the crank) use the same fuel pump (Motorcraft PFS170) as the GTs.

So the GT fuel system should be good to at least 315 to 320 rwHP.

No, i haven't done anything to the fuel system. Hence the thread. I have heard of people making about 400 whp with the stock fuel pump. Isn't the fuel sytem a return style stock? Its sounds like the injectors are what is the biggest limiting factor?
