65mm TB??

[Rob_eaton]

folks, i was looking into upgrading my TB to the 65mm TB, i guess it allows more air into the engine and therefore better throttle response. However, the stock svt TB is 66mm ????... if anything, the 65mm one should decrease throttle response???

anyone clear this up for me

thanks a lot

I'm having a brain fart here, so bare with me. But I think the stock TB is a 64mm if I remember right??? Anyways, the performance/aftermarket TB's are enginereed different;y, with much better throttle responce, also, imo, not really worth the bang for the buck unles your modded up, just more of a creature comfort mod if you ask me.

You have to measure the ID of the TB. The stock SVT is ~62-63mm internal diameter. Stepping up to a 65mm or 67mm TB will provide added low end torque (as noticed thru better throttle response).

I run a CNC'd 67mm TB on mine.

Yeh, factory always measures OD of the TB, and aftermarket measurement is always ID.
