I got a 02 gt so far i have a o/r H-pipe and cat back and a bbk CAI the next mod im thinking about is a bigger throttle body. What would be the best size to put on my mustang???

get a throttlebody and plenum combo. 75mm should be perfect.

I was thinkin 70mm i think 75 is a lil to big.

it cant hurt to go too big. 75 is going to help you down the road when you start doing more mods.

That's true. My goal is to get my car fast enough to beat my friends 99 firebird formula.

thats gonna take some work.. Ide do the usual boltons and some nitrous.

Yea thats what i was thinking, he has gotten it into the high 12's with only L/T headers and a Y pipe. So im going to have to do some moddin to get to that level.

if you think the 70mm is good, and the 75mm too big...why did you ask in the first place? some guy on here posted a thread dealing w/ dyno pulls using these two size TB's. the 75 won out in all combinations. they are the same price. the 75mm will allow for better perf. from possible future mods, w/out sacrificing any thing right now. simple choice for me. i went w/ the 75. go w/ the accufab 75mm.

Get a 75mm tb hands down. I suggest the accufab tb/plenum combo.
