Well my question was based on the fact that someone said it has a 80mm tb stock... which now I know is not true! It is 65mm stock...

so it makes sense that a 70 or 75mm tb will yeild better numbers.

Any word on a 80mm tb coming out??

and.. BIG question.. when is Ford Racing gonna start making stuff for our new stangs???

their website and catalog is still aimed primarily at the 5.0's!!

like the my last post t/b without changing the plenum some a 1-2 hp increase at peak but lose up to 15hp from 3000-4500
so in turn a t/b will slow you down

and there is no need for a 80mm t/b unless you have a built stroked motor running a blower or turbo pushing 20+ lbs of boost
