i think 70 is pointless cause even if u stay n/a if u start making big power a 75mm will still be better

the accufab is only worth it if you want looks. the cheapest tb/plenum is MAC, which is what i had. it put down 2RWHP more than the accufab at my local speed shop. they wanted to put accufab to the test.


also, throttle bodies don't really add crap for power. i gained a whopping 6RWHP on an already blown GT.

I have accufab 75mmtb/plenum and love them. Haven't dyno'd yet but getting close. Get the 75mm and call it a day. Then your done no matter what you do.

70mm is fine with an n/a car. didnt tell much difference with my 75mm.

save your money and put it towards something else. tb is not worth its price and doesnt do any more than a catback

75mm will help you out in the long run of the modding world...

None of the aftermarket t/bs are going to perform significantly better on a boltons GT than another, regardless of size.

You will not see signficant gains between the 70 and 75, or really even the stock 65 and any aftermarket throttle body, espcially with a boltons only GT.

I got my 70mm t/b cause I did it at the same time as the plenum, and I didn't know any better. IMO it should be one of the last bolton mods that you do (unless you just have money laying around).

A midpipe, headers, gears, or even a catback are all going to show much more impressive gains (with the catback doing so sound wise instead of power wise) than a t/b. you would be insanely lucky to see 2-3 WHP out of any aftermarket t/b compared to a stock one.
