porting S5 wastegate
I did a quick search really didn't see a lot of info. Wonder if someone has a link on how to modify the S5 wastegate.
I have a full racingbeat exhaust and when ever its cool enough outside I hit 16psi on a stock fuel system. What can I do to modify the wastegate to cure this issue? 10years ago I modified my S4 which is easy to do but the S5 is different and it doesn't look like there is a lot of material to remove to increase the wastegate size.
Thanks,
Ian

The smaller WG port can be opened up a decent amount. I think it was 18mm originally, and I took it to 23mm. The larger port I took to 26mm. I left around 1-2 mm on the edges to allow the flap to seal properly.
As gxl90rx7 mentioned, you can take around a 1/16" out of the backplate to let the door open further.
