Does anyone know the size of a stock throttle body
Does anyone know the size of a stock throttle body on a 2003 Mustang GT 4.6 litre? I am curious of the size then I want to upgrade to a larger bbk throttle body because I have a twin screw supercharger on the car right now running the stock throttle body. Any suggestion on the size I should upgrade to would be also appreciated.
Thanks

Dont need the plenum
I don't need the plenum because I have a twin screw supercharger that sits ontop of the engine with a stock throttl body attached to the arm of the saleen series IV supercharger. So you say the stock size of a 2003 mustang gt throttle body is 65mm? I appreciate that I think a 75mm on this supercharger will be a big increase for air to the supercharger?

It won't hurt anything to any great degree (a slight decrease in charge velocity at WOT, that will hurt a bit at higher RPMs when the 2V heads don't breath so well), however as long as you run n/a it also won't do anything that a 70 mm TB (and aftermarket plenum) couldn't...

after reading your comments that u posted about not going with a 75mm tb, not to be a smart *** but i was looking at your bolt ons and your hp.compaired to what i put on i gained more rwhp from that.i have c&l plenum,bbk75mm tb,bbk cai,and tune by donnie walsh jr.i got 255 rwhp 300torque this was also at 92 degree temps w 30% humidity.i should also add that i have a cheapo pace setter h pipe,and 100,000 stock mufflers.
