LSA Supercharged 1972 Monte Carlo Hits The Dyno! Will It Survive?

Watch on YouTube

What happens here

During the first attempt at a dyno pull, the operator manually shifts the automatic transmission via the tuning laptop. Unexpectedly, the transmission puts the car into reverse when selecting a forward gear, causing the wheels to spin backward and forcing an immediate abortion of the run to prevent damage to the vehicle or the dynamometer.

Goal: Perform a dyno pull (unsuccessful due to transmission issue).

Tools and materials

  • Dynamometer Dynojet — Measuring power
  • Laptop — Running tuning software and controlling the transmission
  • Tuning Software HP Tuners — Adjusting engine and transmission parameters
  • Vehicle Chevrolet — The car being tested
