can they tolerate heat better than the oem seals? say if you ran hot at the track would these hold up better than the oem versions? i know if you overheat your car just once it will destroy the seals but how about if they're the viton Rotary Aviation versions?

 

stop it. . . just stop it!!!!

 

 

The viton seals can withstand more heat than the factory seals,can't remember
the heat rating.You need to start using the search function otherwise you'll get slated everytime you ask questions like this.

 

The damage caused by an overheat is 2 step:
1) the overheat causes the layered engine block to warp. usually some portion of this becomes permanent.
2) the soft seals that are now exposed by the warpage quickly deteriorate due to inadequate protection.

Both are detrimental to the engine's performance, and the seal material will only delay the final result. Overheating kills engines, period. The only thing that might work would be switching to an all-steel set of housings, which would warp less under very high thermal loads, but that a) doesn't exist that I know of, and b) would make the engine much heavier.
