Thank you, Trev, for your kind response. Uncharted territory here, of course. The downstream of the reed valve N2O injected 2-stroke looks promising, but unfortunately I cannot be the guinea pig. Alas, an easy decision for the non reed valve Maico 490. I am otherwise a very modest person and I want to inject about 200hp into a single cylinder stroker. REVO needed. I will use Methanol and/or Nitro Methane as a fuel enrichment, carb stays on gasoline. I will also add a water injection system.
I expect that a 60 hp 2-stroke can be injected 200 hp worth of N2O but half the N2O with Nitro Methane might allow the engine to breath more air/gasoline and the bottle would last twice as long. I wonder how much oil must be added to the enrichment fuel since Methanol would be twice as rich as gasoline, and Nitro Methane about nine times as rich by weight.
I have heard of castor oil, Blendzall and UCON (Polyalkalene glycol). In case someone is interested here is a link to an oil that can be blended into Methanol and/or Nitro Methane (german language):
