Between the ceramic coating on the exhaust pipe, and the stainless foil (really thick foil) that I have on both the upper and lower cowlings, I hope that the heat won't be a problem. I also have the whole back end of the cowling open, so air should be whistling through there like a wind tunnel. I'll worry about cooling drag, and reduce the outlet down once I'm sure that it's running cool enough, and I have some stats on the temperatures. I'm thinking about getting a wireless temperature gauge from Radio Shack, and monitoring temps at different point under the cowling.

Looks like you are taking allot of abuse from Rusty > over this turbo. I think he's weakening. :) >Looks also like I'll be replacing the water pump. Good find. Looking at you're engine pictures I'm wondering if you'll get a lot of radiant heat from that exhaust inside the cowl. If you do, you might consider sawing it off and extending the turbo shield rearwards with ss as I did to get the heat out the back. I'm seeing no problems with the heat on the prop, plus this gives some augmentation to suck cold air into the NACA. Just a thought. I know you wont want to change things around this close, but if the heat becomes a problem this would be an easy fix.
