Default Nitro vrs. RPM's

If you have x engine with x prop and change only the fuel nitro content is there a given rpm increase ?
ys 120, 16x8 prop ,15% nitro runs 8800 RPM's
Same as above with 20% nitro would probably turn how many more RPM's ?
I Know this has lots of variables but just a round number.
Thanks,
Roy

No given as it depends on weather, temperature, compression ratio, and plug. In fact if you have a high compression ratio engine more nitro can slow it down. You just have to try it, and try it with colder plugs.

76,

I run Performance Plus YS 20/20 and get 9000 with a 16x8 APC. I turned about 2-300 less with the 15%.
