Hopefully water-cooling will help and I can copy that too lol. Good luck.

I have been studying my waste gate issue and I am pretty confident I have figured out the problem. I still plan to run coolant though them since I have water cooled waste gates but I do not think they are getting over heated. The cause that I have figured out is that I was using the Anti lag function on the Haltech and that was the cause of the burned up waste gates.
here is what I have thought about.
1. I raced my car for half a season with out any issues.
2. I used the Anti lag launch function at a couple of races mid way through the season.
3. Next race blown waste gates. I repaired the waste gates after I found the problem. unfortunately I raced at the Toledo Ohio Solo with low boost as a result.
4. New waste gates installed for Nationals, first day of Pro Solo ( using ALS ), resulted in low boost for second day. I finished third but maybe the Low boost helped more than hurt.
5. Turned ALS off for good after that and I have not had an issue since. Also the waste gate that had the most damage was the rear one. Yes, it is closest to the exhaust but it also has the most direct "straight" path from the exhaust.
Haltech has a disclaimer on using the ALS they should ad "will destroy waste gates"
Also added more pictures for ABS, Diff brace and exhaust tip.
