Fair to say every time you're saying "race fuel" you're referring to leaded gasoline race fuel, right?
Renegade E112 is leaded e85... I don't want people to confuse it with something like Ignite e90, which is 90% ethanol with 10% gasoline. There is no 112% ethanol fuel :)
If this was a turbo car, the gains would be even more because with the additional fuel needed for e it creates more exhaust gases - something Dr TuneEmAll mentioned recently. I thought that was interesting.

Nice experiment!

I believe Micah specifies the fuel types and ethanol content of the E112 in the video.
For reference outside of the video the "Race Fuel" is Renegade Pro120 and the ethanol is Renegade E112 which is 85% ethanol and 15% gasoline.
E85 at the pumps is anywhere from 50% to 90% ethanol and the remaining content is not required to be gasoline - it can be other liquid that burns similar to gasoline.

This would assume that you are not controlling boost.
In that case I would agree that if boost is not being limited that the additional boost would produce additional power.

Great video. Ethanol is always the way to go. Octane might be lower, but it cools the air charge. Would have been interesting to see side by side comparisons of MAT on both fuels

I don't know how the different fuels would impact the MAT but I did check for you anyway and they are identical with gas and ethanol.

That makes sense since it’s measured before the injectors

Cool experiment. A few years ago I was pretty against E85, I just didn't see the point with the cost of upgraded fuel system components in "some" cars. Now with the Redeyes coming with dual pumps, aftermarket dual pump setups being less expensive, plug and play, etc, I think the only other add on is the larger injector. If you have E85 pumps in your area it's a no brainer ESPECIALLY compared to gasoline.

Having had both, these cars really like E85 even cruising around there's a big difference on how they drive. I did run some oil analysis and did not find a need to change oil more frequently. Caveat, I drive my cars all the time so they never "sit" which may be where the oil change frequency has to be more often.
