I just bought a CFM 67mm TB, and was wondering everyone's opinion. Is it really worth it, or did I just waste $250? I guess I should have posted this before I bought it. Oh well!!

Not worth $250 IMO

you get throttle response but thats not worth $250 to me, more like $50


Like OrangeSVTguy said you can bore out the factory one for a few bucks.

is it worth boring out the stock svt throttle body? I did it on the ztech and it seemed to help. I just didnt know if the svt stock throttle body could be ported out anymore.Thanks,Jeremy. Didnt mean to steal the thread.I didnt want to start a new one first this topic.

you get better throttle response with the cfm TB no profrmance gain just better response when taking off.

I agree on the stock porting giving the same throttle response......

and as long as you dont go F/I with that throttle body you should be fine.....those TB's dont like forced induction.

its all in what you like. got mine before they had the 67 so i had to settle for the 65. the throttle respose i very diff and the port for the idle air control is smaller on the 65 then on the factory. the aftermarket doesnt have that slow tip in like the factory due to it haveing a flat butterfly instead of the ski jump looking butterfly in the factory one. if it was me id keep it.

I bet you could port the aftermarket 65mm to a 67mm

The stock one is plastic, like on the Zetec, right? That's why it's easy to port. All you need is a Dremel. Every aftermarket one I've seen is aluminum...which could prove more difficult to bore....

The idea of trying to bore and screwing up and having nothing or one with a crack is not very comforting. If you have the cash, might as well support your third party suppliers. It keeps them in business and making parts for us.

SVT parts are thinning out.

Ok. I finally got the TB on and it is a different feel. I don't think it is worth $250 but it does improve greatly with the throttle response. I almost had to really learn how to "re-drive" the car. I appreciate all the responses.

yeah its only ever really worth it if.... you have high rpm NA talking 7k plus... or have a roots blower. The increased throttle response comes mostly from the revised butterfly in it. Sanding off the wedge gives the exact same feel.

Yeah I think I'm just gonna try and bore mine and install a newer thinner aluminum butterfly plate in there. The stock one seems to be too thick and I think the thinner aluminum plate might more air in and I won't have to bore it at all [:D]
