MM&FF Plenum article, have a question.

[XStanger]

In the article they state that the intake is installed with the stock 70mm TB. My question is this TB inferior to other 70mm TB like Accufab/BBK ...? They are the same size.


I am just trying to justify spending more money if not needed.

i thought mustangs came with 65mm stock?

 

[XStanger]

I thought that as well, but the article said they installed with stock 70mm!

 

[JonJon]

Bizarre.. Maybe they meant Ford Racing 70mm tb

 

[mogs01gt]

I think the stock TBs start out as 70mm but taper down to 60 something.

If your talking about the C&L plenum test, they tested with the stock 65mm TB and a Ford Racing 70mm TB.

Yeah....the stock TB on the GT is 65mm

IT comes down to one thing. is the tb truly as advertised. I have read that the ford 70mm has a taper to it. basically is the manufacture being truthful. I think they should all publish flow #'s.

so in this cas the ford tb may no be a "true" 70mm. I would like to see flow #'s on all the tb's. do the cheaper ones like mac and FRPP flow just as good as accufab or bbk?

Just get the accufab 75mm TB and the C&L plenum. For $400 the HP/$ is more than just a catback for the same money.

 

[StangLou]

Does anyone have concrete #'s on the accufab 75mm tb with the c&l plenum? Are those #'s better than the accufab tb/plenum combo? anyone know the exact deal with these combos or are we all just pulling #'s out of the air?

if i remember correctly, there were some model years that came with a 70mm stock. i believe it was 02+.

the Ford 70mm t-body is the same as the 65mm except they bored out an extra 5mm right where the blade is.

If your talking about the C&L plenum test, they tested with the stock 65mm TB and a Ford Racing 70mm TB.

No, they said they tested with the stock 70mm TB and then added the 75mm and it gained like 2 hp.
