NASCAR uses a special ethanol fuel and they are performance engines.Not at all recommended, Flex fuel engines/E85 certified are specifically built for both fuels. I doubt there has ever been a performance engine built for flex fuel since ethanol gives lower HP output and less MPG. You need to add in that the mapping of the ECUs are specific to Petrol
Of course not road legal but...
EDIT: Never mind that fuel is only E15.
