Hope you mean 400degF. I will get a photo of our latest out - it is big with a last little kickdown. . Last week I sat around one nite with about 6 people with Mr RV (Richard Van xyz) and he says the out of engine air is the most important thing and he discussed the last little kick down as we sat in a hangar with 2 different suck out Pawnees. The NSW AIrcadets Pawnee was much more than Brad Edwards IGR Pawnee
400degF corresponds to 205degC which I believe is 25degC too high. 370degF is 188degC which is aiming point for full power. If you have EGTs it is MAX full power 1256degF (ie 680degC) BUT at 70% power it can rise 25degC more. The bonus of a cool engine (ie <180degC) is you NEVER have to adjust tappets from one 100hrs to the next 100hrs I have something from the Sonex people who do the Aerovee engine Ian mcPhee On 6 December 2010 21:55, Maree, Hannes <[email protected]> wrote: > Hi Doglist, > > > > A while ago there was a discussion regarding changing the air outlet of the > Dimona to reduce engine temperatures.
