Aluminum has some interesting properties. It will not discolor with heat but rather plasiticise when approaching the melting point. I wouldn't expect a total meltdown or "vulcano" as I breviously joked but I would expect a lot of warping or distortion over time if this were used in a regular gasoline powered 930. Your challenge likely may be oxidation. EtOH has some corrosive properties and moisure is of course one of the exhaust bi-products. I don't know off hand what you could treat the outside with to keep it looking nice.
Please keep us informed on how this works for your application. Pretty neat.
