Nitro % suggestions

Nitro % suggestions
I currently use Byron's Race fuel (20% nitro). If I'm going to start racing should I move to 30%? I see alot of, no actually make that most people, using 30% nitro vs 20% or 25%. Now obviously if there is a nitro limitation this won't apply. Generally speaking, if I'm racing and I'm new to racing. Should I just stick with 20% or go to 30%?
Also, how does running higher Nitro affect tuning? As I understand it the easy explination is that higher nitro requires slighter richer carb settings right? But with that is the engine noticably faster with 30%?
I did a search and I got more questions than I had originally before I searched.
P.S. I am going to stick with Byron's fuel after numerous recommendations and my prior experience with it.

I found this info that might be helpful in answering your question:

Fuels with a higher nitro percentage, like 30% for example, burns hotter and creates more power, but the engine also consumes fuel faster and you have a greater chance of overheating your engine. 10% nitro burns cooler and is a little more efficient fuel, but it doesn’t create as much power. 20% fuel is a good all-around mix between the 10% and 30% as you’d assume; it burns hotter and creates more power than 10%, yet is cooler and doesn’t deliver as much power as a 30% fuel would.

That link was also pretty helpful. I use 20% now, but I don't race yet...if I was racing I was wondering if I should jump right to 30% but I wasn't sure. I'll stick with 20% for now.

I would first check w/ the mfgr to see what your engine was designed for. If it is a true race engine, it will run better w/ 25 or 30%. Here's the problem. If you live here in the U.S. 25% race fuels are hard to come by. Byron's 30% Race is a very good fuel, but you should consider adding a shim (.10). Most high quality race engines are pretty easy to tune, even with 30%. I run a RB C6, and that engine is much easier to tune than my p.o.s. t-maxx engine!!
Last, if you bump up to 30%, you need to go through a short break-in process again.

It's a JP Modified Mugen X12. I know it will handle 30%, but I was wondering if I needed that and if the difference would be immediate.
I'll try 20% to start off and see what happens.

You don't need to stay with 20% if you aren't that experienced IMO. Just switch to a cooler plug, add a shim to prevent predetonation or pittingof the piston if the mfr setting is for 20%, and you'd have to richen up the engine a little. I swapped to 30% and it's very easy to tune. I didn't find it hard to tune at all and tried it with atleast 5 motors when I first swapped to 30. They all ran very well and a lot faster.

Well, I have a fresh gallon of 20% that I just got so I'll use that up and then maybe switch to a 30% after.

If you want 25 % nitro fuel get a quart of 20% and a quart of 30% and mix them together in equal amounts. make sure they are the same oils and oil content.

What about blue thunder fuel, don't they make the 25% mix. I am in Singapore and that seems to be a very popular blend. Not sure about the US?
