Depends on what the goals are...if everything was the same price I'd get a 70mm one as it would match the cobra upper opening, but that would be the only reason.

Dat 75 is too big for ur set up, get a 70mm or keep dat 65. Put sum headers on dat thang while ur at it.

If i was your boy i would keep the stock one, Once he figures out what he will be doing with the car/motor h / c/ forced induction / nitrous, that way he can calculate what size tb he needs rather than buying a 65mm only to realize 6 months later he needs a 70mm...

Interesting, so how do you calculate the TB size for a supercharged car?

Psi ÷ cubic inch + 14 x 2 - 37 = throttle body size

VELOCITY !!!!!!

everyone talks about "flow capacity" like it's gold

velocity is whats important, imagine sucking on a straw that was 1" compared to a straw that was a 1/4"

get it ?
