if the KB S/C's for the 5.0's are like the ones for the 4.6/5.4's it takes place of the intake manifolds and the throttle body attaches to the port of the supercharger. i assume youre going with the 2.1L standard or blowzilla S/C since thats the only two listed on their site.

as for horsepower, its a shot in the dark and probably a lowball but im thinking 400-425 crank horsepower.

 

it takes place of the entire intake manifold or just the upper?

from the looks of that i think it takes place of the upper manifold, my bad on the first post. hopefully someone with more experience will chime in.

you could also go with a turbo kit or centrifigul s/c kit

i think a member of this site makes a really good turbo kit for fox bodies for around 2,900 bucks

 

Mustang Turbo Kits theres the turbo system if youre not dead set on a supercharger yet...

 

A roots type charger is going to add a lot of torque to a motor that already makes a good deal of torque on its own. I personally think a centri blower is your best bet with these cars.

 

Yes KB replaces only upper. And fits under stock hood perfectly. The install is just as easy as replacing the upper, only one existing hole needs to be drilled bigger and minor grinding. Is says on instructions that you should cut the ac hoses, but theres no need, i didn't even evacuate my ac. Just bended the lines.

I know that turbo makes most power, but you can have very much hp with twin screw also, and the instant boost + easy installation finally turned my head, havent regretted.

 

Most of the guys running the KB setup run out of steam at about 400 hp.

response is definitely better. So it really depends on what you want to do.
