Hi Gary,
Are these results from the same engine you had at the AYA Sacremento
convention?
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.
Best Regards,
Ned

I'm pretty happy with the results. The stock cowling would have been a lot
worse. 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.

Hey Ned.
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.
