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

Watch on YouTube

What happens here

After further fine-tuning of the fuel map and engine timing, the car is put back on the dynamometer for another pull. This time, the vehicle achieves a peak horsepower of 503 horsepower at the wheels. While an improvement, the power slightly drops to 497 horsepower on a subsequent run, which the host attributes to increased engine temperatures. This highlights the importance of maintaining optimal engine temperatures during tuning. The team decides to let the engine cool down before attempting further pulls to avoid heat-soak related power loss.

Goal: Maximize horsepower output while monitoring and mitigating heat-related performance degradation.

so that power bump was just from the fuel difference it was 11 degrees same timing as the 93 no lower less so you're adding more let's see what she does do you think we'll make over 500 yeah okay here we go i think we'll make over 500 this time we'll see that sounded like some more power did we make over 500 this time [Music] 503. sweet there we go 500 500 at the tire and we're still what 10 11 pounds yeah did you find the wide band where was it right where you said it was no john i think you got played i think i did two i walked over there three times [Music] like you know maybe someone stole your cats someone stole my cats where my cat's at them down the hairy lines to be about already but it's it would be hard to say on 10 pounds but with smoothing off you can see it dipping in and out of powder
