What Is Going On? Current Status on ALL The Builds! LSXcalade + LSA Monte Carlo "Ralph" + Uncle Rob!

What happens here

The 'Uncle Rob' GMC truck is currently undergoing a fuel system upgrade. It was recently dyno-tested with a turbocharger at 10 pounds of boost, upgraded injectors, but with the stock fuel pump to assess its power output reliably. The plan is to install a new DeatschWerks (DW) fuel system, then re-dyno it with the same boost level but running on E85 fuel to compare power gains. Additionally, the rear brake lines, which are heavily corroded, need to be replaced while the fuel tank is dropped for the new fuel system installation.

Goal: Upgrade fuel system and test power gains on E85 fuel.

Tools and materials

  • Brake Lines — Replacing corroded rear brake lines
  • DeatschWerks — Upgrading the fuel delivery for increased performance
  • E85 Fuel — High-octane fuel for performance testing after upgrade

on here we'll start with the most current one uncle rob a lot of you guys are probably following that series if you're not you should check them out uh right now i'm not a bit of a spoiler alert but a little sneak peek i'm putting in the deets works fuel system dropped the tank all that stuff going on that we just dyno'd it with the turbo 10 pounds uh upgraded injectors with the stock fuel pump to see how much power you can make on the stock pump reliably like is it worth doing can you get away without changing the fuel pump that video is pretty freaking cool uh i won't ruin the numbers for you though because we also dyno tested it with the stock injectors to see what they would max out at so we have physical numbers for every step of the way we're gonna do the fuel pump test it again that way but the first test for that will be same boost level just going e85 to see how much more power it will make on the same boost level as 93. so we're we're doing everything step by step providing numbers on the dyno for science for you guys that's the current state of the union on uncle rob uh today i got to go around and grab some brake lines because the rear ones are super rotted and sketchy looking and while the tank is out i want to change those escalade if you haven't seen
