Subject: [FlyRotary] Turbonetics T04 rotary flies

After a lot of delay from out-of-town work, patio rebuilding and "cut &
paste" stainless steel work on the heat shield, I can finally report
that the new turbo T04 installation flies. The one issue I had on the
0.9 local flight was an erroneous EGT reading. I installed a new sensor
and it's reading very low - 300F.

Boost still has a tendency to run away above 44 MAP. I've been gradually
tweaking the boost controller toward minus on each ground run, but the
wastegate doesn't seem to be doing anything. So far I have about 1.5
hours ground running on the turbo. I held her at 40 MAP for take off
which was more than enough to get me 80kts less than half way down the
3000' funway.

Take off acceleration seems to be a little less than with the stock
turbo. There's no sign of oil or soot on the prop and the oil (recently
changed) is staying "oil color". With all the stock turbos the oil went
black within an hour of running.

Perhaps now, finally, the fun begins.....
Regards,
John Slade
