Gasoline burns hotter in a diesel engine than diesel fuel does because instead of a controlled slow burn, it explodes suddenly. This is because the mixture of gas and diesel does not ignite instantly, but builds up briefly before the diesel part catches fire, thus setting off the gas part. If you fueled it with pure gas, it would never fire, but the mixture does ignite, and then the gas part explodes. The sudden release of energy in a very short amount of time, especially when first injected as the piston is still coming up in compression, results in a momentary extra hot flame that can result in damage to the engine.
It is true that diesel fuel contains about 10% more energy per volume of fuel than does gasoline. But the difference between an explosion and a slow burn more than overcomes that small difference.
The EGT indicator on my aircraft says the hottest I can get is 1600 + degrees, running 100LL at wide open throttle, The Pyrometer on my diesel boat says it runs at 2300 degrees wide open.
what you are suggesting is the the gas in this mix will detonate prior to the diesel burning. With a mix this diesel rich I do not believe your theory, simply because this mixture 85to9 gallons simply will not lower the centane numbers any significant amount.
