40% nitro will make the engine critical, I suggest not to go higher then 30%.

The more nitro you use and the performances will be higher but also the internal stress of the moving parts.
If this works out for you then it is fine with me, as for the life of the engine, it will be shorter as when you use less nitro, however how much is impossible to quantify.
I suggest with 40% nitro you check your engine on regular bases and change the conrod after each 1 1/4gallon burned through the engine.
