If an engine is designed to run on 25% Nitro fuel (.21 off road engine)
Can i run 16% nitro fuel if i wanted to with out harming the engine, if i tuned it correctly to suit it.
Or are these nitro engines like real high performance 1:1 car engines, that will ping/pre detonate from fuel with a lower ron/octane rating???
Check with the manufacturer about head shims. You can run anythingd from 10% to 30% assuming you add or remove the proper number of shims. This prevents pre detonation when running higher nitro content race fuels. You can run 16% but for best results check with the manufacturer about whethee or not your engine is shimmed and you need to change that.
