If so, I think you would get better results with a 180hp engine. I would expect a lot lower CHT's and a more pure data base development for use with the STC for 180hp Tigers.

As long as it's under 500 degrees, that's all that matters. Besides, with the EI type setup, the CHT's will be around 70 degrees cooler.

Good response! I wonder if you will hear back from Gene! I enjoyed talking to you and seeing your plane at MCC. Just wish we could have found the time for me to go for a ride in it.
