wedge? on throttle body butterfly

[momento1]

anyone know the reason for the wedge on the butterfly as per the pic. At WOT is looks like it would restirct some airflow...
It kind of looks to me like they were aiming to directing airflow however if im going the reverse intake path i dont see the point of it...
any input would be great as im thinking of removing it and pluging the holes.
Cheers

He is talking about the 20VT throttle body. I deleted it on one of the S2's I owned. Can't tell if it made a difference as I did a lot at once then.

thanks quattrostyle
so no ill effects then after you removed it??

sounds fine to me, i dont see the need for it really

[quattrostyle]

No ill effects AFAIK, I did get the ECU throwing a code every now and then after multiple times WOT though. I can't remember exactly but it was a 5 digit number and starting with a 5 as well I believe. That could have been caused by multiple factors I guess.

It's there for part throttle control to make it smoother and more progressive, if you remove it or make the throttle body wider it becomes very twitchy to pedal response

There's been a few threads on this but I remember this one on audifans http://www.audifans.net/ftopicp-65432-.html

He didn't like the results on removing it!

034 offer it as a service IIRC

[momento1]

so its probably fair to say that it smooths out part throttle.... which probably makes sense thinking about it... but at WOT it looks like it would dampen air flow a bit....

ok i guess it stays in place for now then...
GT3071 turbo upgrade is almost finished... !!!!

[Jamo]

There is no way it's going to restrict a setup with a 3071 turbo

[momento1]

every bit counts.....

I didn't think twice before taking mine off, again I did a lot of mods at the time so can't comment with and without it. I can say however that with Dmitri's mapping it runs like a swiss watch. You'll need to plug the 2 holes it leaves behind though, I countersunk them both sides and used some solid brass rivets. Whatever you do, make sure it can't come out!

I didn't remove mine altogether but i did reduce its size, There is a pic of it in the Audi Driver magazine , will try and dig pic out at some point this week.... Actually prefer it as I get better part throttle acceleration but still good control when cruising...

if you could dig up some pics that would be great...

i would no doubt get used to the throttle responsiveness in a short period of time anyways, and its not a daily driver... so maybe i could bare with having it gone, or perhaps at least reduce the size of it as 20Vcqdriver has done

we machined out the throttle body by 2mm and made a 2mm bigger flat butterfly , i got the idear from 034 site , fitted to rally car so its not on part throttle much if at all

Don't you run a restrictor anyway Ray?
