Nope. I'm using 80mm MAF w/ optimizer from Pro-Flow. --Matt Originally posted by 99SVTguy:
Are you using the stock diameter MAF with your new TB? Any error codes yet? I'm way interested in this mod. Seems like a larger TB/injectors/MAF combo works great for the stang guys. I know our motors have a very high specific output, but I think there's more in it. Thanks a ton for taking pics and putting together some instructions.
Oh and here's my $0.02:
I just think its funny how skeptical people are on this website, especially when it comes to new mods. I mean, if folks would just be patient while this guy finishes up testing and tweaking his mod and tests it, then maybe some of this arguing could be avoided. Seems like if we put all of our knowledge together rather than arguing about air velocity, inner diameters, and Roush's modification strategy, we can come up with a solid modification to help keep our cars faster than the pack....in case you haven't forgotten about the new breed of imports soon to hit our shores from honda/acura and nissan.
Keep us posted man...I'm all ears...and thanks!

First: Steve, if ya ever make me read something that long ever again........LOL Second: Bret as far as flow dynamics is concerned 3mm is huge. There is alot of air that can flow through a 3mm increase in tube size. As far as why is the TB the size it is? Well lets see, something about epa rings a bell.... Third: someone out there is working on a dual throttle body setup (not sure who  ) and we will see how that works....xchang you know who is doing it?

Actually this is a bit odd...
63mm has 31.1 cm2 of flow area or only about 10% more than the 28.3 cm2 flow area of the SVT 60mm
So why only increase TB size 10% with an increase in displacement of 20% (not to mention increased CR, headers, porting/polishing etc)?
Bret, are you SURE they checked larger T.bodies on the dyno. Id guess that if they had, a bigger T.body may work better. But this is just a guess.

Re: 63mm TB
Is this even an available size from Ford or elsewhere? Seems to me that maybe Sho Shop simply bored out a 60 and made a new plate for it. In terms of wanting to offer something for sale that would sure be a lot easier than having to fab up a new cable or do more involved mods to make another tb work. Chances are they didn't know the 65 could apparently be made to work so easily.
Just my $0.02...

Bret, are you SURE they checked larger T.bodies on the dyno. Id guess that if they had, a bigger T.body may work better. But this is just a guess. by that logic the proper tb size for a 10.0:1 5.0L would be like 100mm...

Well..I had to postpone the dyno runs. I had to take the SVT back to the dealer because the alternator was over charging. It fried the wiring and the battery. I should be able to get it done next week.
Sorry for the delays.

just to put some things in here if you bore the 54mm you can only go to 57mm difference of 3mm sho shops throttle body is also 3mm larger. when you bore a mustang tb from 65 you get 68
coincidence? no
If a naturally asppirated honda gets a PROVEN dyno gain from a 68mm on a 1.8L engine
How can you concieve theres a lose why do these companys only go this much larger COST. I believe there will be nice numbers.

I just thought I would chime in here to let people know that you DO NOT NEED TO MODIFY YOUR CONTOUR'S THROTTLE CABLE. If you clock the throttle shaft through 180°, the stock Contour throttle cable AND cruise control cable all hook up to the Mustang TB's connectors in the same way as the Contour TB. Trust me I have done it. And if you check my write up in the 65mm TB install in this Performance section, you will see clear pics showing everything you need to do to make the 65mm TB work perfectly on the cContour, which I can guarantee carries over to installing the 70mm TB.
