Paul

Now that you have been using the economy tuning kit for awhile,  what kind 

of EGT/RPM are you seeing upon climbout and in flight cruise.  Also what is 

your field elevation which may affect these numbers?



Thanks

Ivan

Ivan,



Not sure if I am the Paul you posted to but, I have been using the original  economy tuning since it came out.  To be honest I will have to take another look to give you a good answer but my field elevation is at 5300 and I do most of my flying at 8,000 14,000 feet.  If I remember right climb-out is at 100kts, 1900 RPM and EGT's run 1275-1375 with the cruise numbers about the same but the speed running 150-160 kts and at full throttle 3150-3250 with the EGT's running 1025-1025.

Should have been 1025-1125 not 1025-1025.

Your climb-out is 100 kts at 1900 rpm? Is that right? Seems too low  

for rpm, especially at 5300 ft MSL...must be one fast/slippery  

airframe. I'd sooner think 2900 rpm, eh?

You are right Lynn it should have been 2900 RPM. The Q-2 is slippery but not that slippery.

No problem, Paul....I'm just glad that I don't have to re-prop my  

plane to try to get it to climb at this rpm. : )

Does anyone have the manifold pressure readings to go with climb and cruise numbers?
