Which Fuel Makes More Power? Race Fuel or Ethanol?

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!

Maybe if you squished it REALLY hard...?

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
