I think this is the engine that is having the problem Rob.
Not really a 914!

Correct, 912/914 doesn't really matter. It won't run R plugs over 30"

45-50" for 15-30sec is no problem. I don't run any higher cont boost than regular 914's.

Hi Thomas,

I'm with Rob, 45-50 is too high. 40 is max. see attachment
