Kenne Bell on my ride

Hmm, what about with a 8lb pulley ?

That's odd though, your saying it will only add around 40-50HP, That don't make no sense, even the smallest Vortech does almost twice that though, I thought this blower would be good for 150HP or so with my setup ?

Ya even right here http://www.kennebell.net/superchargers/ford/mustang50/mustang50.htm it says a 137RWHP gain on just a stock 5.0 & an additional 30 horse on top of that by just adding a pulley & the flip chip alone supposably is worth another 25, by just doing the math I should be expecting somewhere around 150-200+ extra rear wheel giving me somewhere around 450 or more rear wheel atleast, that don't make no sense ?

Well, keep in mind that the only things that are going to help you out on the breathing end are the heads, 1.7RR, T/B, MAF and exhaust. You don't get to use the upper intake or the U/D pulleys with the blower install and your set up isn't all that radical to start with. I think the figures that I quoted you with just a 6psi pulley are pretty close. I bet you I’m not more than about 10hp off. These 5.0L KB’s produced loads of low-end torque but aren’t real high horsepower makers. Don’t be fooled my Centrifugal numbers. Most of them are Dyno queens and don’t put nearly what they make on paper to the pavement. This KB on the other hand makes use of every single horsepower it produces!

Go with the 9psi pulley and I could see you tacking up near the 400rwhp mark, but as for reaching the 450-claimed hp on a 1500…..Not a chance. Not with out some serious mods….for starters that stock camshaft would have to go.
