aftermarket throttle body

[gtstang86]

my stock throttle body is 70mm. is there any advantage to buying to buying a aftermarket throttle body of the same size? i just have some minor bolt on mods so i dont think i need anything bigger than 70mm.

Your stock throttle body is 60mm if you have a 94-95 5.0. There is an advantage to upgrading, however, if you have a few minor bolt ons you probably don't need it.

I agree.

One 70mm throttle body may not flow like another 70mm throttle body, if that is what you are asking

Shaft thickness, blade thickness, screw protrusion, and finish shape can vary between different brands which changes flow potential.

Also remember, unless the intake's opening is 70mm,like the throttle body, you aren't flowing all "70mm"

Sorry to hijack, but it should help the original poster... Would anyone like to chime in with their opinion on which aftermarket 70 or 75mm throttle body will flow the best? Has anyone done research to prove one brand better than others?

George Klass has stated many times that their throttle bodies flowed the best, after he compared them to the competition.

With that being said, George Klass is at Accufab

I haven't found any articles describing a direct TB comparison test so I can't answer the question directly. I do have a Summit Racing 75mm TB which is a very nice piece, and I ported the upper intake manifold opening to match. Throttle response was much improved and I like it.

I am planning on a GT40 head swap with the upper/lower fully ported, but want to put on a 75mm TB would that be overkill or should I just go with a 70

A larger blade is doing to produce the same thing, described in two different ways:

1. More throttle response.

2. Touchy throttle response.

A larger surface area blade will let more air in at part throttle, but in many applications the wide open throttle performance is unaffected.

Wow that was extremely well put. And makes complete sense.
