What happens here

To confirm the suspected fuel pressure drop, the team attaches an external fuel pressure gauge to the engine's fuel rail. The presenter then uses electrical tape to secure his phone to the fender, positioning it to record the fuel pressure gauge's readings during the next dyno pull. This setup allows for live visual monitoring of the fuel pressure under load.

Goal: Physically observe fuel pressure during a dyno run.

Tools and materials

  • Electrical Tape — Securing the phone for recording
  • External Fuel Pressure Gauge — Monitoring live fuel pressure
  • Foam Mat — Protecting the phone if it falls
  • Phone — Recording the fuel pressure gauge
  • Wrenches — Connecting the fuel pressure gauge

soon as you start as soon as you punch you deserve to go let me just let me just fire it up and let it idle and see what it is island okay with the vacuum on it 62 on your gauges my mine says 58. just making roughly 10 pounds of boost so with it being boost reference it should be around 72 and we're going to 40 so we're losing basically 30 pounds yeah so she's not gonna she's not gonna hold up yeah we're gonna have to fix the the fuel pressure before we can see what it does well dang at least it made some actually kind of progress that's right well we've we've got the you know made a few changes to the trans tune to where it doesn't downshift now and we we didn't make a pull in reverse so yeah
