Great job guys. Congratulations!!One possible issue?
Many years ago I worked at Garrett AiResearch. I assume you have check valves in the turbo oil feed lines at the lowest point to avoid oil drain back? This was an issue on the first Offy turbo engines built for Indy in the 1960's; we had bearing failures that occurred on restarts with hot oil. This engine too had turbos mounted high up. Some engine builders also use an accumulator or auxiliary electric oil pump as well.

So the idle advance is about 10 degree, max at 3000 rpm is 40 if running without boost. When hitting that 1.5 bar/22 psi, advance is 20 at 3000 rpm. Those numbers are not a dyno proven, so those are results of hunch of team's brainstorm aided by more badass turboracers.Doze So if anybody got more ideas to this soup of speculations, feel free to leave a comment.

Alan, that garage wear was there for a purpose BigGrin. Last time we did the same, exhaust pulses made a huge dust cloud out of a dry sand and that was a no no with open turbos w00t.

11,95 is quite good with 292 cid, ~8.5 cr and small exhaust outlets, I think.


THAT would be an understatement! That's real good.w00t
