unfortunately I ran it already now Im just hoping that with use the rings would seal again and get good rpms I was told they do 7000 rpms on a 28x10 menz
our gas here has 10% ethanol would that be a cause for low rpms?

[RTK]

Who told you 7000 with a menz-s 28x10?? You can get close with a mejzlik 28x10, but I think the menz is more load than the mejz, if memory serves me.
Hell, just set the needles, put it in the air and fly it for a few gallons. I doubt you did any harm.

6500 on vess27B is quite low.
What mufflers?

[BBLIZZARD]

3w-150 old style mejzlick 32x10 standard muffs w/ walboro carb

5900-6000 rpm

my da-150 turns 5500-5600 with the same prop

both are great motors and super reliable. using 93 octane and moblie 1 rt2 syn oil.

[Flatlandman]

DA 170
RE3 pipes 14" header
Mezjlik 30x13 evo prop
6350 rpms

MVVS 50 on MVVS 3280 muffler and Mejzlik 23x8 prop, 7600 rpm (~6.55 hp)
MVVS 58 on MVVS 3280 muffler and Mejzlik 24x10 prop, 7800 rpm (~10.3 hp) Peak rpm cold at 8000.
Data are from MVVS dyno tests: I will ask them to confirm.

Edit:
MVVS just confirmed above figures. Put that in your pipes and smoke it guys!
The data were obtained with the new 3280 muffler, especially designed for higher rpm operation

after 2 gallons my BME116 runs on a Vess 27B at 7000rpm from a 10 minute flight
switched to a menz 28x10 after a 10 minute flight now turns 6300 rpm after a 10 min flight 6600rpm when cold!! is this good?

[pe reivers]

About the same rpm as the MVVS 116 on cans with 28x12 Mejzlik. Sounds quite good to me.
Which mufflers did you use?

This is why MVVS-Evolution will always be at the top of the heap in my book.
A true hot-rod engine.
