LSXcalade Hits The Dyno: Makes INSANE HP at PFI Speed! (8,000 RPM Twin Turbo LSX 427)

Watch on YouTube

What happens here

With the Escalade already producing over 1600 horsepower, the team prepares for a final push. To combat rising engine temperatures, an additional large cooling fan is added to the setup. The presenter also humorously points out he finally fixed a hanging air hose he'd been hitting his head on all day, a small victory amidst the high-stakes tuning. Further timing adjustments are made, noting the surprisingly low ignition timing (around 12.5 degrees) for the power achieved. The final recorded dyno pull is then performed.

Goal: Conduct the final dyno run after maximum safe adjustments to achieve the highest possible horsepower.
