Some gamma TiAl alloys can stand that effluent temp just fine - no need for the complexity and cost of the yttria stabilized metastable cubic zirconia TBC attached with some intermediate, expensive MCrAlY or precious metal aluminide connector thin film which has already created an intermediate oxide layer for EB-PVD columnar attachment of TBC. Don't mess with me on this one... See 2014 F1 rules. Let's not talk about the products of combustion of oxygenated (can you say naptha) fuels...circa 1980's F1 fuels (rubber gloves and masks)...
