i have been doing a little more experimenting and getting some better results,although my TR still wants to be a little on the hot side for the best performance. this may sound like a really stupid question and i think i know the answer but i will ask anyway. if i ran 30% nitro would i be better off as far as temp? i was thinking that with a higher nitro content i could put more fuel through the engine(run it richer) hoping that maybe the increased fuel through the engine would help keep it cooler-yet not bogg it down because i have a higher nitro content which burns better? i dont know, just a thought
