Yup, that's how you make more power with alcohol - higher CR or more boost and advance. The advantage to alcohol is the resistance to detonation and the higher latent heat of vaporization that allows you to run higher CR's. The way they made more power was to increase the boost (and possibly the CR but they didn't really need to since they could increase the boost) and optimize the advance and fuel curves.P90Puma said:It's actually pretty easy to get alot more power out of any boosted engine using E85 (Ethanol) as it has such a high octane rating so you can crank up the boost futher without knocking.
