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.....
