I reckon the manufacturer would probably know what they are talking about so if they say 25% then thats probably a good start & the best choice.

More nitro than recomended can do more harm than a lower content.
It is up to the topicstarter what he is going to do with the engine and what he wants to invest. In the case of racing he needs to keep the rules in mind. If he just want to bash arround and want to save some money 20% is perfect to run.

Why not lower than 25%?

Explain how?
The nitro content also shifts the ignition timing, more nitro makes it sooner what will give more load on the rod, crankpin etc.
But yes even at the advised nitro content you can damage an engine if you do not know how to tune or using a bad fuel.
Over here in Europe we have a 16% rule and many 25% setup engines are running 16% without any issues.

Go with what you can get. I know around me there is no such thing as anything less than 30 lol I wouldn't run anything higher but I can personally attest to someone who ran 50% home brew drag fuel through his Roma no problem. Engines are made to handle today's fuels. All of them. That's like a Volkswagen gti that takes regular but performs best on premium fuel. Just get what you can locally in the 11% oil range and have fun.

Awsome feedback guys....im probably going to stick with the recommendation of the engine %25. But if I do decide on 30% what would be the Benefit?

A lower percentage of nitro also effects ignition, causing your engine to labour harder and also not burn as clean. Causing more strain and stress as youre pushing harder to get the same result.just because it can run it, doesnt mean it should. A performance car works alot better when running a higher octane fuel as opposed to a lower octane. Burns alot more efficiently, cleaner and also causes less stress on components as youre getting a better ignition... go run 98 octane for a week and then drop back to 91, you will notice the difference straight away. As the engine wont run as well on the lower octane fuel.

Lower nitro content gives a later ignition. The combustion starts further beyond TDC what will lower the load/stress on the components. The amount of powerdifference between 20 and 25% is hardly noticeable.
For the topicstarter, running on 30% will give some extra bottom power, if you can notice it.

Novarossi engines run great on 25% there is no reason to run 30% whatsoever.
You arent going to save money buying nitro less than 25% either. just run good fuel, i personally thing byrons 25%nitro 11% lubrication is the best. Vp has some good fuel as well. Only some crappy hobby shops charge more for higher nitro percentage, if you look online, 20% and up all costs about the same. maybe a dollar or so variance. I remember a hobbytown usa that tried to charge 50$ a gallon for traxxas 30% top fuel, what a joke.

I have always ran 30% nitro in my Novarossi engines with no problems when I use to use them. 30% is more widely available in my area than the other nitro percentages. I would stick to Byrons, Werks, or Bones Brew for fuel as they have the most consistent blends and best oil packages available. For some reason, my Nova engines really liked Byrons Pro Driver 30% with 9% oil. Ran really crisp and strong.
