Inside the throttle body on the butterfly there is a portion of metal that screws onto the butterfly itself,what affects will this have on the engine if it was removed,it looks like it stops the airflow or does it deflect it in some way??

Wondered when this question would come along, had the same question but never asked about it. Removed it on my old S2 though. -
I think, it's there to smooth airflow between idle and throttle starting to open.
I further believe that in a NA motor, throttle body makes no difference. I am running a twin throttle body system on a 7A and it gives 2.5 Kw.
On A turbo set up with forced air induction, and unless you plan on running to 10000rpm, throttle body makes very little diff. But thats just my logic at play and it may be way off.

The wedge acts to reduce airflow when the throttle is just opened. It smooths out the throttle so its not as jerky at the top of the pedal.
I have removed it on a few different cars and it does make the throttle more jerky when you are on and off.Comment
