Do you still have one of the strobe power packs available?

I can't see an exhaust leak either. And I've thought about putting some heat shield on the cowling, but there is almost no room between it and the turbo; about 0.75 in I believe. I'm afraid that an additional constriction would leave even less air to flow past the turbo. I may install an additional air vent in the front to direct more air between the cowling and turbo. As far as TIT goes, I had a TIT gauge installed last week and will hopefully test it tomorrow. Any suggestions on what temps are normal and what's too are greatly appreciated, since this is my first turbo airplane

When I bought the plane (with the turbo already installed) there was absolutely no heat damage. When I used the turbo the first time, the cowling cracked and paint burned. My mechanic then stop drilled it and sprayed the white paint on it before flying it again to see if the same thing happened with the turbo off - it didn't. As far as I can tell there's no sign of an exhaust leak, and I do have a CO detector showing clean air

Peak EGT temp was 1550. I kept it at or below 1480 while using the turbo. MP was kept between 23 and 25, and RPM 2400 throughout the climb to 14000
