Hello Net
Thanks Bill for the "Brain fart". The trap door idea is good. However my main
concern is that since the turbo is nearly at the top of the cowl, and close to
the right side. After shut down the fiberglass is hot. Unless the trap door
was at the top, the heat would still be trapped. I need a thin thermo blanket
to protect the fiberglass. I spent my airport time today reworking my baffles.
I placed the rear baffle behind # 3 cylinder about one inch aft of the head so
that cooling air could circulate to the back side of the head to increase the
cooling area exposed to the cold inlet air. It also makes a better separator
between the head and the turbo down pipe. I also reworked the right side
baffle so that the stock oil cooler has more fins exposed to the inlet. After
all was complete, I made a test run to check performance with the waste gate
closed. Today the engine ran 3100 with 31MP with the throttle wide open. The
outside MP was 29.96
