Turbo LS Horsepower Test! E85 Ethanol vs Pump 93 Octane (What's The REAL WORLD HP Difference?)

What happens here

The video opens with a quick clip of the GMC Yukon XL performing a dyno pull, followed by the host and tuner discussing the project's goal: to dyno tune the vehicle on E85 fuel. The previous dyno run on 93 octane fuel yielded 450 horsepower at the wheel. The expectation is that E85 will result in approximately 100 more horsepower without changing the boost level. This initial discussion sets the stage for comparing the performance differences between 93 octane and E85.

Goal: Understand the project's objective and initial performance benchmarks.

well it's like smoking a lot now did we just kill it it's time to dino uncle rob again but we have more fuel pump now we are on e85 we're not gonna change the boost level we're just gonna see how much more power e85 makes over 93 octane so if it's 10 pounds now on pump 93 versus e85 um it made 450 at the tire before should make 550. you think it'll make 100 more horsepower just by changing from the 85 yes
