The thing that made the biggest impression on me wasn't the (excellent) SAG research, but a little tidbit shared by Doug during his dyno presentation. It, like the SAG question, didn't have a final answer, but I suspect that it has the potential for improved cruise efficiency.

Doug mentioned that they saw the repeatable effect of increased power when they disabled *either* the leading or trailing injectors. I have my own idea about why they saw that, but I'm hopeful that there will be some discussion & eventually, a proven way to increase cruise efficiency.

Questions for Doug & Steve:
When this was tested, did measured fuel flow change when the injector pair was disabled & rpm went up?
Did you by any chance try to duplicate the effect while in cruise flight by flying on 1 pair of injectors?

As I mentioned to Steve in a hurried conversation Sunday morning, I have a suspicion of why it's happening but I'd like to see more research. If the effect turns out to be consistent across multiple installations, there could be an easy efficiency improvement on the table, waiting to be picked up & used.

Steve, Doug,

I'd love a copy of your test file, & to talk more about it, if possible. You can give me a call any afternoon, or email me your # & I'll call you on my dime.

Thanks...601-879-9596
