Default Real world RPM
Giants members,
Being as we are always getting questions about what kind of power you can expect out of motor/cannister/muffler/prop combinations, how about we post all the numbers in one thread?
please post actual numbers. Include as much info as you can. Probably don't have to remind anyone,but no product war here guys. It's a Flying Giants service. Let's see some numbers!!

DA 100 on standard pipes with Menz 28-10 = 6100rpm. 95 octane, 50:1 castrol TTS.

35 degrees celsius, as good as at sea level.

Question..... does a Mejlik spin faster or slower than a Menz on the same motor?? Anyone done back to back between the two prop brands???

DA 150 "Sala Series", Airmodels 32-11, KS 1080 pipes, MTW 12" headers, 70 degrees,1100 elevation. 87 octane fuel Aimsoil Saber100-1. The reading was registered after a 15 minute flight, not with a cold engine. 6080rpm 1st reading 6040 second reading.

A cold engine can give you a couple of hundred more rpms.

DA 50 XOAR 23-8 prop, KS 1060 pipe on a full length header. Same fuel and conditions as my 150 above. 7100 rpms.

My buddy Dan is getting 7200 rpms with the only change from mine is muffler. He has a new pipe from Mark Doan. This pipe produces a ton a power.
