Good link. Good information. What I get out of the article is that use the "good stuff" only if your engine is designed for it. I think the YS and later model Saitos are designed for it and benefit quite a bit from the higher nitro. Hence that is why when I use the incredibly accurate fish scale thrust test I see a good bit of diference in thrust with the the YS and Saito engines. Yet with the Magnum and most 2 strokes I've tested I don't see the benefit. But one thing I also believe is the engine runs better on higher Nitro. It will transition and idle better if you use higher Nitro.

Good article, in my mind it backs up what my primitive tests have shown with facts. Don't understand the facts, but I do understand the power increase I see in my engines.

Thanks
