Deciding on which nitro fuel to use

[Shaun_TLR]

Hi all,

Im currently considering running an 808 nitro roller as its intended use (nitro). I had intially bought it for the parts as spares for my electric.

I am now looking at buying a nitro engine (see seperate thread for my noob nitro esc' questions on engine choice) but wondered what should be considered about the fuel.

Do I need to run the engine for the whole of its life on the same fuel? What do I consider other than just price.... do they differ much in quality? Obviously I guess local supply is one consideration.

Do certain branded engines run best on carter Nitro % content or certain branded fuels?

Any help would be great

thanks

All engines can run on different fuels however i heard that bullit engines like pirahana fuel and 25% is the race legal fuel now it was 30%

Nitro content in fuel varies, normally in the range 16% (ready to run) - 30%.

In a race engine (Bullit, Alpha, OS, RB etc.) you'd normally go for 25% or 30%. 30% is slightly easier to get a good idle on I find, and offers a performance advantage, however all but the best drivers won't notice! 30% is pretty much being phased out too. If you do go for 30 you may have to re-shim your engine head to alter the compression, the motor will most likely come with the shims and guidance on this.

As for brands, I always used Byrons as it was easily available, but Piranha, Firepower or any of the others will do just as well. Pick a brand and %age and stick with it. You can change brand if needed but would have to retune the engine so it's easier to just stick with a brand. For my money, 25% Byrons Gen2 is as good a place to be as any.
