Hello,
Considering the rise of the price of the gas, I am wondering if it would be possible (wise?) to implement a flex fuel conversion kit on my 2011 Range Rover L322 V8 5 liters Supercharged, to be able to use E85 ethanol instead (or in addition to) of regular gas.
I was wondering if it would create some problems with the engine of if this implementation is ok ?
Any help appreciated,
Thanks
Eric

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

Not sure about factory built performance engines, but there are plenty of performance engines built and tuned on E85. It is a popular fuel in the performance community due to having a higher octane rating, typically. Plus, the engines run at a lower temp. It's an awesome fuel for purpose built engines.

NASCAR uses a special ethanol fuel and they are performance engines.

Of course not road legal but...


EDIT: Never mind that fuel is only E15.

Thus proves my point for our engines. Our engines are not purpose built for ethanol. Our engines are nothing like the ones Chevy produced for the mid west where vast number of trucks, Suburbans etc run on ethanol.
