RE: super tiger 3250 help
Because this is not a discussion forum, we're going to close off this thread, but we're going to leava a few notes..
We've done test runs on the G3250 with an APC 18 x 10 prop and see RPM ranges, after a thorough and careful breakin, of up to 8,100 RPM at the very peak. We normally see about 7,800-7,900 RPM. The engine can easily be run consistently as low as 7,400 RPM with a slightly-larger prop. Lower RPM would not be recommended unless you have very good cooling. Our tests are normally done with normal Omega 10% fuel, which is what we run through every engine that comes through our shop, except some of the more exotic engines. If you're going to use a low-oil "SuperTigre Fuel" with this engine, then we'd strongly suggest that the majority of the oil be castor, and that you go no lower than 12%, especially if you're running the larger props.
