Throttle Body Question

[GreekStang85]

hey guys i am looking at buying the accufab 75mm TB with the accufab Plenum and i want to know if a 75mm TB would be too big for my application. i will have longtubes and off-road h pipe soon with my mods listed below so would the 75mm be too much or good??

Go with the 75mm. I e-mailed Accufab about wether to go 70mm or 75mm and they said for my 00 GT with K&N intake and cat back with power programmer to go 75mm with their upper plenum.

i think i might choose the 75mm

i was told the 75 was for heavily modded engines like supercharged, and the 70 was for ones with lighter mods, i was lookin for a new TB and if a 75 is better id rather get that what to do?

i plan on getting the 75mm one day

75mm Throttle body works fine with heavy and or lightly modded stangs. You will get good HP either way.

I plan on the 75mm Accufab w/ C&L Plenum. to accomodate the Mac str8 shot system I have.

How did the 75mm affect torque? Did you lose some low end and gain high end?

personally i dont see what a 75mm TB would do for ya unless the intake opening was ported to 75mm or close.
65-70mm is safer to use for near stock configs

Go 75mm- though you may not supercharge your engine- you never know how your mod plans will change in the future and if you go 70mm it would suck to have to upgrade again at a later date!

I used the 75mm Accufab TB with the Accufab Plenum.

I went with the Accufab 70mm TB/Plenum based on the Modular Depot write up and was very pleased with the increased performance.

75mm all the way, and dont look back.

I have the 75 and the plenum and am happy with it. I didnt want to out grow the 70. I did not see a feel a drop in the bottem end but the top really comes on strong.

75 sounds good to me
