65mm Throttle Body

Ok, other than looks is a 65mm throttle body going to do for the SVTF? I could see a reason to get one for a ZX3 but the SVT stock throttle body is already 65mm. Can someone explain to me what I am missing here? Thanks

It's weird that the 65mm TB will give you more HP/torque than the stock 66mm TB that comes with the SVTF. Maybe someone can shed some light on this issue.

65mm

what i have read from those who have them is this. there is a very small gain on a normally aspirated motor. there is a better throttle "feel" as the bore is smoother than stock. there is also a 70mm available. the general consenus was it was not worth the 2 or 3 extra hp it makes on a non blown motor for the money.

We dyno'd one way back when it first came out and it was only worth a few hp. Probably not worth it for the N/A guys like was mentioned.

I always wondered why ford would make the stocker 66mm, kinda an odd #.

seb656= a throttle body goes in between ur intake and ur intake manifold. it lets the air into the engine. its got a larger butterfly (hole) than the stockers do so it lets more air in. it also helps with throttle response. i got mine a few days ago and its great.

I am not sure you will see much of a gain from a 70mm T/B either. You can only shove so much air into the intake manifold.

hmm

I'd only purchase an aftermarket TB if I had a Supercharger or Turbo. The gains on a mild SVTF don't warrant $200.
