But I'm sure you've thought of that as well.

I hear you there Neil. My main thought on this was to get the exhaust (and therefore the heat) out of the cowling ASAP. The cowling penetration would of course have to be lined, and I know I will be lining and heat shielding around the turbo itself as we proceed. How much, remains to be seen in ground runups. Too bad all that heat can't be used for something........... Greg
