With the potential nitro shortage and or cost increase, I wonder if raising the compression on common US market engines like OS 46’s to convert to methanol only would work on these engines to retain near nitro performance. I know the OS makes an ethanol engine already, but what about those in circulation. Something like an exchange program, the customer sends in his cylinder head (cherry condition or pay full price) and the customer gets back a head that has it’s deck, squish band, dome (reduced volume dome) reconfigured with maybe an anodize color to signify the conversion.
What do ya guys think?

Most engines and your OS46 will run nice on 0% nitro as it comes from the box. All you have to do is changing the glowplug for a hotter one OSF, Enya3 och OSA3.
If you like you can remove the head shim and see if you can squeeze out a few more rpm at peak.
