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
