Just got a great intake and throttle body job done!
Gary (gesTTalt) and I both were test cars for an entry by Wilson manifolds into the European car scene. These guys dominate the field in V8 NASCAR and drag cars. Now they are doing Audis!

Keith and his guys over at Wilson Manifolds did a great job on Gary's and my 225 intake manifolds. They did before and after flow test of the manifold and the throttle body for comparison. The numbers are very strong -- a total of 16% increase over stock airflow on average on the runners and a 17cfm increase in the throttle body after modifications.
Here are the numbers broken down:
#1 (before) - 196 cfm - (after) 240 cfm
#2 (before) - 216 cfm - (after) 246 cfm
#3 (before) - 212 cfm - (after) 246 cfm
#4 (before) - 218 cfm - (after) 244 cfm
average before # - 210.5 cfm
average after # - 244 cfm
This is fantastic, plus the very sweet machine work with the Wilson logo (machined on the CNC)

the throttle body end of the manifold

the new manifold with gasket, notice how much closer the opening matches the gasket now

the throttle body. Keith took a lot of material off both ends to open this up as much as possible. Notice that the once round pivot rod has been shaped flatter to obstruct as little flow as possible.
Gary is installing his as I post and will have VAG numbers this evening we hope. I am very excited to get this on my car later on this evening. Wow this is so cool :-))
BTW, Gary and I can hook you up with this work for any Audi. Just let us know :-)<ul><li><a href="http://www.wilsonmanifolds.com/">Wilson Manifolds</a></li></ul>

Does not require new programming, I think the MAF will account for the increase flow...
But this is the kind of mod that a chip, and exhaust will only make better :-) Retail cost for the manifold is $850 and $550 for the TB.

I doubt it, send yours in and get it back in a few day (3) was my experience...
nowever this place does all the Winston Cup and Pro-Stock, etc. work so big race events will affect the turn-around. I can hook you up. :-)
