Ford 6.2L - Thoughts
Thinking about upgrading the truck. Looking for something in the 7-10yr old range. With the Ford, that crosses from the V10 to the newer 6.2L V8. I guess I hadn't been paying attention. Wow, 385...

Again, MORE fuel is injected, thus the power is still maintained. Did you know that many race cars use alcohol? Because ethanol is an oxygenated fuel, it can run at a richer mixture.
Also, e85 has a higher knock threshold, so you can run more ignition advance.
If the timing is normally reduced to allow running regular e10 87 with the high compression ratio's in todays engines, you can gain power running e85 because you are able to run the ignition timing the engine actually needs to reach it's full potential.
Just because e85 has 30% less energy per unit (or whatever the percentage is), doesn't mean you lose 30% power. As said above they just have to inject more fuel, hence the fuel mileage loss. Wether you gain power all depends on how the factory tuned it for e85 vs e10.
