it wakes up your car so when you gas it you get more power much quicker, there is a notice, you won't gain any horsepower, maybe gain what you already lost from your old TB, a TB will only add HP if you really supe up your engine, with a turbo and aftermarket exhaust manifold and such

I've always wondered what the inside diameter of the short ram intakes or stock intake is. If you had a 67mm throttle body and the air intake was smaller it would create a bottle neck. anyone know what the ID is on the air intakes?

i feel like its right around the 67mm TB size, because when i was putting my together, the connector tube thing, i put it on the TB, and then put it on my short ram air, and it looked like when it was stretched out the same size, or very close to it.

they should make it so they just put the filter cone on the TB with the sensor right there aswell, more air? haha or would it just fail epicly

and a new bigger TB pretty much gives you more low end torque, your start offs will be much more quick

Well, my Focus is a Sedan, compared to your SVT (also, mine is an automatic). I wonder if I'll still notice as much a difference as you did?

No Turbo or manifold, but I will be adding a CAI, Cat-Back Exhaust, and header. Will this specifically allow the TB to gain HP? I know my mods will gain me some HP overall, but I'm wondering if the TB will add to it? If not, I'd still be up for the excellent throttle response and better get up and go.

As my car is now (stock) it's an absolute brick.

i think you'll still notice a difference when you change it out, if you buy a CFM one which i think you should, it'll be all metal, nice clean thin metal gate thing that opens and closes, which the stock one will be plastic, the turning gate thing isn't even flat, and it'll be dirty. at least mine was, i think it is a good investment if you're looking for some pep.

i don't think those mods will do anything to help the TB gain HP, maybe the CAI because more airflow will be coming it so that may help it a tid, especially if you decide to get a bigger TB, i got the CFM 67mm, so worth it

It's weird how just 2mm makes a difference. I believe stock is 65mm. But like you said, I'm sure the plastic vs metal makes a difference. But with my current TB, the throttle response is not very good. At least not in certain RPM ranges.
