Ken,

Just realized I did not answer your question........I do not think the TES seals

will raise oil temps.........I just hope that their ability to handle more heat will

make them less likely to go away at oil temps that might be pushing the limit

with Viton seals.........I am just eyeball engineering also.........

Ken,

Your point is well taken and may very well be valid.........I do not expect

or advocate a mass run to change the seals (rotor or coolent) to TES.......

I expect a few individuals (myself included) to try them and see how

they hold up as Tracy would say "In the real world".........My primary

aim was to first eliminate the problem of "What size"........Next will be

how they perform in flying engines........Chuck Dunlap is currently

flying with TES seals in his rotors and reports they are doing fine........

I am still waiting to hear how many hours he has on them.......
