You can run e85 through nismo 740cc. Yes e85 has less power per unit and uses more fuel. Limit on hp for 740s for e85 is in the 500s. The main benefit of e85 is reduced chance of detonation because it burns cooler, big advantage in Las Vegas. Also don't run an electric cooling fan, they are like 1/4 the cfm and really won't save you that much power on a street car.
