Lvis,
Please state the point of this or I will close it.
There are probably 100+ 04s and 05s with a MM tune on them. Asking if there is anyone with them, is largely pointless. Most people don't change the redline.

i think he left mine alone. i know the tach isnt accurate but my fuel cut looks like 9600 on the tach. i could check it with my ap if you want.
op is in danger of getting RIWWPROLLED. lol

Rotor tips can hit the housing due to imperfect balancing and/or e-shaft flex.
OEM assemblies might be balanced sufficiently to exceed 9,000rpm, but they are more likely not sufficiently balanced. You don't actually know how well balanced yours is without a rebuild. E-shaft flex is another problem that will limit it anyway. I don't know of any 2 piece e-shafts for the Renny yet?
Aviation rotaries probably aren't just dealer remans...

I had my rx8 set to 10k rpm by MM because there were some chicanes where not shifting was faster than having to shift once more. That's the only reason I asked him to do it.
At what rpm do aviation rotaries run?

Why would you want to rev the engine beyond where it actually makes power while hugely stressing the internals\bearings etc?

Aviation engines typically can run a largely fixed RPM and vary blade pitch for thrust changes. In this case, they will want to run the engine at the torque peak, which is also the efficiency peak. Where that peak is will depend in their intake and exhaust design, any porting, etc...

I know the older engines were limited to 7k due to the bearings, I thought that wasn't the case for todays engines?
I think I confused aviation with race engines, in which case its a mute point as those engines rarely see more than 1 race before its rebuild time.
At least we added substantial substance to another thread
