The turbo hardware induced BSFC difference is minor. What is needed for power is octane by meth or ethanol. Selecting meth means the fuel system upgrade is not needed, especially if a proper flash, such as Procedeflash is applied. The upgrade is needed running 100% e85 without meth.

Ok, so if somehow a set of RB's magically could produce enough volume to reach 650whp - your telling me that they would not require more fuel than your single turbo setup? Please explain
