Stock Throttle Body V.S. CFM 67MM
 
Has anyone done this install and is it worth the money to do with it going from a stock 65 to a 67 just curious and am in consideration of new ones. Thanks for the help

I just went from a OEM TB to a Focus Central 65mm TB and it is night and day.

I gained 2.4 WHP and 7 ft-lbs TQ. I actually have a 18 ft-lb TQ gain in the midband@4750 RPM it's 10 ft-lbs(where it matters).

I just had my cam gears adjusted on the dyno this past Saturday. It was a good investment as well. Now I sit at 133 whp and, 126 ft-lbs TQ.

Identical thread in the SVT section, which the car is and the 67mm is specific to.

Thread closed.

(I can't merge them)

And to the OP the bigger TB is great for throttle response however won't result in much HP gain. I installed a 65mm on my Zetec Auto, it was the BEST mod I ever did.

No, you'd have to replace the whole intake system to see any noticeable gains. Manifold, TB, and Intake. Then you might see 2hp gain from a 67MM TB vs Stock. It isn't like a Fox Body going from a 65mm to a 105mm. Our manifold is the most restrictive part of our intake system and they even did a good job with DSM.

I dont think anyone has proven gains with this... Just better response... If u saw gains maybe it was dynoed on a diff day, colder car, other or with mods installed

Do it. The stocker Is way less than 65mm.
