RE: Norvel Engine FAQ
CP: I had a chance to fire up the 074 with a 5-3 prop and 15% nitro a week ago. No it didn't blow, it did peak at 22.5k. I was kind of proud of it.
I am boxing it up for warranty return. With a 7-3 APC RPM's never exceeded 9K - what a pig.
I called the phone number the warrenty sheet mentions, it's on your dime and you do not need an RMA number. Return your engine CO Justin.
