Mike,
this forum is for Legal eagle's, an ultra-light that was designed for the homemade/homebuilt handyman, KISS rule applies here, there is much here about modification, i have much experience with volkswagen's but generally speaking heat is what shortens the life of any engine, especially one's with aluminum heads.
BAD idea period dont take it personally why dont you ask the expert here Scott Casler? the racing world of vw has the proof also.
Peace
Theo
