Like you, I've got a GS45 that I use as a bit of a test mule
. On 25% all castor (no nitro) it spins an APC 10x6 at 14,600 which I think isn't too bad.

With an APC 9/8 prop (recommended by Super Tigre) it ran 12500, but was very unstable. I have read, like yours and what Bax has told, it should turn at least 12500… Last night I made some modification on the cylinder, and look forward to se the effect.

Well done, it's good to see actual test results and, like Pe, I'm not a believer in skimping on oil. I think your HP figures are way off though because you can't have varying HP at the same revs with the same prop but the running characteristics are the more important finding here.

HP figures way off??? I couldn’t image anything else!
I can clearly read the difference on the kitchen weight, when I tested the mixtures, and then calculate it into HP. Perhaps it’s the toque that changes. I wouldn’t now.
