Any development of a throttle body for the Ecoboost

I had the BBK throttle body on my 2011 v6, and it did indeed add better throttle response as well as a little bit better power between 2k-4k.

I'm wondering if there is any value in a larger diameter throttle body for the ecoboost and what that value would be.

I only saw one other post that talked about the silly throttle body spacer, but nothing about a throttle body in general.

I was always under the impression evacuating air from the engine was more the weaker point of this 2.3 engine. Which is why modification to the head is being done to help the air flow. Maybe after the testing is done with revised head, turbo and internals this may expose weakness in the throttle body.

Usually on a turbo setup a larger tb is not that important....on a PD s/c setup it is.

Anyone have any pictures of the stock one? Any blending needed?

The Stock TB isn't that bad, the issue you will have is the tuning side of things. There are a lot of parameters and tables focused around the throttle body on this car, and if you change the physical size of it you will have to do a whole world of math to get the tuning right. If you don't you will have stumbling issues, high idles, poor throttle response, or simply limp mode.

I had my stock TB ported by maxbore you may want to check out his site. http://maxbore.com/

That's pretty interesting. What are you impressions of it? Worth the money?

Not sure if it solves the same problem but my Pedalmax rockets the car off the line, it's so crazy quick that I can barely use it in sport mode.

And with the remote control knob the % is adjustable.

I believe BBK already has one. I don't think anyone here has bought one yet.

Yeah they do and state it's a drop in mod no tune required. What is the stock TB diameter?

throttle response seems to be faster after installing it. TB looked bigger/smoothed out, the blade is definitely thinner, and no surging issues. Idle is smooth as butter. Here are before & after pics(after pics the TB is still in the plastic from shipping).

I'm no expert on turbo cars but this seems like a pretty cost effective performance mod. Any increased airflow should be good, especially for those with a turbo upgrade.

I have noticed while watching some data from the PID for actually throttle body position, that while the pedal is to the floor the TB is sometimes not even more the 60% open with the stock tune. I have heard that the PCM controls the PSI to the intake manifold by closing the TB to get desired pressure. Maybe the OP's tune is much more aggressive though and is actually letting the TB fully open for a good amount of time. Otherwise I wonder if a better TB is really helpful for turbo cars where normally aspirated engines always want the least restriction.

WE have BBK's here for testing, going on big power cars with billet intake manifolds. For stock turbo cars, airflow isn't going to be an issue so the throttle body upgrade cost would be better spent somewhere else.

This is on your GT, right? Totally different than on an EB.
