Default Switch from 20% to 30% Byrons on Losi 350?

I am wanting to know what are the benefits of switching from 20 to 30 on my losi 350 if any? I have ran about a gallon and want to see if I can gain some power with 30%

I would really like to know the answer to this as well. All I have ever ran was 20% for the fact I thought I would make my motors last longer. But with the new blends of fuel this may not be such an issue. Anybody like to help us out??

With 30% you'll get a little better cooling, and a little bit more power. The performance gain isn't worth shortening your engine life, I run 20% Byrons and unless I get an engine and fuel sponsor, that's what I'm gonna keep running.

I have run both 20% and 30% and you dont need to worry about engine life. If I can get 10-14 gallons out of a motor with 30% fuel, I cant ask for much more than that. I experimented with 20% simply for fuel mileage, and after my testing I found that yes I did get better fuel economy, I had less bottom end, and less bottom. The loss in power was not the worst thing as I felt it would make a great tuning option, I found that the 20% eliminated a lot of wheel spin which made it easier to drive on a loose track. I just prefer 30% fuel, I like what it offers me. On a final note going to the higher nitro content may require some additional shimming of your motor and some tuning and possibly a different heat range glow plug. Good luck.
