Talking to a buddy of mine at the local High Performance Ford Dealership, he recommended the Saleen SC over the Roush. This guy knows and builds lots of High Performance cars himself, I'll trust his knowledge and experience on this.

Said the Saleen is the most efficient SC on the market for our applications.

I would like to see someone with both the ROUSH and Saleen SCs on their trucks go head to head.

I would also like to see someone with a turbo. I had a buddy play with a supercharger on his Trans Am and put out respectable #'s (400 hp, 450ish torque). He then went to a turbo and put so much power to the ground that the dyno can't read it and he's eating transmissions and 9" rear-ends.

both were pushing about 9 psi, but the turbo really woke the LS1 up. I'm wondering if that is the case in the 5.4 also

PSI for PSI a turbo is the most efficient way to make power. It takes almost no horsepower to make the boost, where as a s/c takes some power from the crank.

The roush kit carrys the factory powertrain warranty after installed. No bs from ford when the tranny snaps in half from the extra torque.

The roush kit is a roots blower. Reliable, simple, somewhat inefficient. The whipple design is more effiecient. Cobra and lightning owners bolt these on for big hp numbers.

Snow performance has a new turbo kit for the new mustang. Single turbo, big HP numbers methanol injection for chemical intercooling. Need a kit like that for the F150.

I've seen one of those methanol kits. they look alot like nitrous kits. I did like the effect though. one pass had 495 at the wheels and 523 torque, second pass with the methanol broke the rear tires loose at 540 hp and we never got a true torque reading. it was screaming up. machine last read 591 before the burnout occured.

so, has anyone spent the 5-7 grand for one of these toys yet?
