Re: Subaru EG33 breaks the class speed record

Steven, I have over 760 hours of run time on this EG33. I estimate that well over 70% of that time the engine has been at 4800 RPM or higher. I have never opened this engine with the exception to replace the head gaskets. I just finished doing a compression test and all cylinders passed with flying colors (pun intended).
The only time that the engine seems to get sluggish is when I run aviation fuel for 20 continuous hours. Aviation fuel has lead in it and I think that the rings or valves were becoming clogged with lead. To clear it up I just run a tank full of auto fuel and she gets back to her old powerful self.
I love my Subaru EG33.
