LSXcalade Hits The Dyno: Makes INSANE HP at PFI Speed! (8,000 RPM Twin Turbo LSX 427)
What happens here
With the Escalade already at 1492 horsepower, the team aims for further gains. They acknowledge the impressive performance given the high density altitude (DA) of 8791 feet, which typically reduces engine power. To increase boost, they adjust the wastegate duty cycle. The third dyno pull is performed. The powerful exhaust notes cause a nearby garage door to visibly open. The results show a new peak power of 1650.64 horsepower at 131.14 MPH.
Goal: Increase boost and refine the power delivery to achieve even higher horsepower.
