CFM 67mm throttle body

[tukaniSVT]

Well, some people don't want to pay the money for such little to no gain. But for the SVT Focus, most of the parts are for drivability not power gain.

Meaning, each upgrade it helps the car move easier and reach it's power band quicker as well. Better throttle response from an upgraded TB is one of them.

The only N/A bolt on that really gains you across the powerboard are the upgraded Cats. The ORP or HFC.

A couple observations about the 67mm CFM TB I just installed. Very nice piece of kit! The stock TB is 63mm...but has a VERY thick blade designed to restrict the airflow during light throttle. Of course the larger piece gives a LOT more air with much less throttle movement and make sure you set the TPS properly. The idle speed will stay under computer control with quite a bit of adjustment so turning the stop screw is really just adjusting the TPS as the computer looks for the lowest value and uses that for calibration.

Another thing...my stock TB would over-center at WOT, meaning it closed back down a little. This is NOT good! The new CFM would do this too....so a throttle stop was fashioned to stop it at 100% open. Check when you install the TB to make sure yours doesn't open past perpendicular.

My gas mileage actually increased a bit with the CFM TB! Reason is the throttle opening is less during cruise which keeps the timing up via the reduced TPS signal.

Reading this thread makes mw want to install my tb haha ... And my ORP and get Toms Tune. Too bad I work so dam much. Smh :/

I have a brand new CFM street HFC, CFM flex pipe & Magnaflow (resonated) CB exhaust; not installed yet. The next purchases are Toms tune & a TB.

Would you all recomend the BBK 66mm for $200 on or the CFM 67mm at $250? I've never heard any feeback of someone having the BBK 66mm?

i noticed the stock TB was for the msot part completely plastic, and that the valve thing that turns in it was plastic and came bent, so it wasn't as big. the thing that turned wasn't completely straight and thin, so it itself was restricting air flow. definitely pleased with this upgrade. now just waiting upon magnaflow exhaust and my eibach sports system kit.

oh and what does "bump" mean on the marketplace thing? i see that all the time and have no clue what that means

Any difference on your mpg? better? worse?

Just recently installed the CFM 67mm on my 03 svt. Definitely a more noticeable feel and response. I don't if I'm crazy but it seems the same maybe a few miles better, but if I get on it often it drops noticeably as well.
