  • BD Screamer Performance Turbo Installation – 2019+ Ram 6.7L Cummins

Installation instructions for the BD Screamer performance turbocharger for 2019+ Ram 6.7L Cummins trucks, a CARB-compliant upgrade (EO D-553-14) for 2019–2022 RAM 2500 and 3500. Review the pre-installation checks first—a new turbo will not fix underlying oil supply or contamination problems.

NOTE: Please read all instructions before beginning the installation.

Applications

This kit is available as two part numbers:

  • 1045772 — Performance Screamer Turbo
  • 1045777 — Stock Remanufactured Turbo

Meets CARB requirements for the following models (EO D-553-14):

  • 2019–2022 RAM 2500
  • 2019–2022 RAM 3500

Pre-Installation

A new turbocharger will not solve any of the following failures:

  • Oil contamination
  • Restrictive oil drain and/or oil supply
  • Overspeed due to boost leaks
  • Exhaust leaks due to faulty seals and/or clamps
IMPORTANT: Turbo overspeed will lead to premature turbo failure. Boost pressure can be used to estimate turbo speed. A restrictive intake or a boost leak will increase turbo speed and cause an overspeed failure. The maximum allowable turbo speed at 3200 RPM is 121,000 RPM, corresponding to a maximum boost of 38 psi.

Pre-Installation Inspection

When replacing a turbocharger, BD recommends the following precautions are taken:

  • Replace or clean the air filter.
  • Change the engine oil and filter.
  • Inspect intake and charge-air-cooler (CAC) passages for debris, and clean if necessary.

In the case of a previous failure, also include the following steps:

  • Inspect the CAC for debris, and clean it out if necessary.
  • Inspect the engine oil for debris. Flush the system if debris was present.

Ensuring that these steps are followed will prolong the life of your new turbocharger.

Installation

NOTE: Verify that the turbocharger and charge-air cooler are free of excess oil and debris. Do not allow any water or solvents to enter the turbocharger inlet or outlet. If necessary, clean the charge-air cooler.

Clean the turbocharger mating surfaces. If the old gasket appears to have been leaking, check the mounting flange with a straight edge. If warpage exceeds .004″, the manifold will need to be replaced or machined.
