Totally understand your price thought but I use E85 as race fuel in first hand, a lot cheaper than VSP fuel and we dyno the same numbers as race fuel.The big hp cars here ran VSP on the streets before and now E85 to a 10:th of the price per gallon (over here).Chezedik wrote:Yes, Ethanol and Methanol both have 76K per lbs. But you actually make more power with methanol injection because detonation causes a severe spike and subsequent drop in combustion chamber pressures (spike before piston is on downstroke, and low press during downstroke) causing a huge power loss. While Methanol may not have the BTU output, it will prevent ping due to it's relatively high specific heat, and high octane. So by preventing knock, you may lose a little power to the Meth, but you are saving a ton due to knock.
I think the jury is still out that you can inject a more and get the same power (meaning to reach a stoich ratio). From what I am finding, there is a very slight power loss, which as everyone pointed out can be offset by more aggressive tuning measures. So it seems the principle drawbacks are lack of availability, and price per mile.
So I have said it a dozen times already, when it becomes available and cheaper than gasoline I will use it.
BTW, it's not about high boost for me, but higher compression and relatively high boost, FTW. <= Better Thermal Efficiency
You only need to run really rich at boost and still possible to tune it cheap for daily driving. Some piggy back or standalone users got a gas program as back up for daily driving but not that common.
Another thing we noticed is the EGT, a lot lower and this will save both turbo, O2 sensor and manifold.
And last, feels good to help our tree´s live a few years longer. We need to start using other types of fuel soon and why not start slow now?Probably stupid to discuss nature with US guys but yeah..
