You also have to factor in parasitic loss of the sc which I have seen on eaton roots blowers to be upwords of 20-25hp. at 12-14 psi.

Say we are getting 18hp of parasitic loss, that means on a stock tc the engine is actually trying to put out 218 crank hp but will only show you 200 crank. Knowing that the parasitic loss will not increase very much running reasonable levels of boost "10-15 psi" over stock and knowing that the engine is trying to put out 58hp above stock before the sc parasitic loss deduction, that comes out to an average of 8.3hp per psi on the trd map. So going to 10 psi should net you 25-30hp. Intercool that charge and you should be netting 28-33hp in theory. Up her to 12 psi and your looking at 40-45hp increase over stock. Even at 10 psi on this type of supercharger your bottom end should improve allot as well since this type of blower produces boost based on rpm woohoo!

Now take zpi's kit on the stock ecm for example. They got what. 230 whp somthing hp out of 6 psi? That means a crank hp of 250 "example" with lots of other mods like intake, exhaust, header etc..

Now take into account the f-trim blower is not awsome but it is efficient for a supercharger. If you were to stick on the trd sc without flashing the ecm, at 7 psi with the same mods as the zpi kit, the car should be running right around the same 230whp and 250 crank hp.

Now take away the parasitic loss of the blower and your at 212whp. and 232 crank. Now install the trd map made to keep the engine together which pulls ignition timing and runs her pig rich to be safe under boost and I could definitly see the trd supercharger putting out 200 crank hp on a stock tc.

Flamming turd burritos batman! I think I nailed it haha!
