Weren't you over 17 for years?
Your sig states 19.5 and I don't believe that was built.
Just trying to normalize the data.

I was told getting above 16 psi is getting into the danger zone. Of course there's no magic number. I think a lot has to do with how often you're in that zone. I was making 17 for a couple years but I don't put a lot of miles on my car and I wasn't at peak boost that often. Since I haven't torn apart my blown motor yet, I'm not sure what caused the bottom end failure but I'm pretty sure it would have lifted the heads if the bottom end didn't fail.
What psi was your rotrex build making when it lifted the heads?
