I have an RV 7, IO-360. cold air induction, one Lightspeed and a Harzell BA prop. On a ground static test to 2600 RPM, I see 23.9 " on the manifold gage, both manual and AFS 3500 digital. All fittings have been checked for leaks. The manual gage was teed into the system @ the engine. Doesn't seem high enough. Airport altitude is 700". What are you seeing and any suggestions or comments would be appreciated. I am already talking with Mattituck.
Thanks,
David
