Cummins Stock Replacement and Screamer Turbo

Pre-Installation

A new turbocharger will not solve the following failures:

  • Oil contamination
  • Restrictive oil drain
  • Over speed due to a boost leak or clogged air filter
  • Exhaust leaks due to faulty bellows, clamps, or seals

Turbo over speed will lead to premature turbo failure. Boost pressure can be used to estimate turbo speed. The table below shows maximum allowable turbo speed for a stock motor at 3500rpm. A turbo intake restriction, clogged filter, high altitude or boost leak will cause increased wheel speed.

Turbo Estimated Airflow (lb/min) Max boost (psi)
1045768 75 lb/min 39

Turbo Mount Exhaust Brakes

The BD Diesel Screamer turbo retains the factory turbine outlet. If your stock turbo has a turbo mount exhaust brake it can be transferred to your Screamer turbo. If you plan on purchasing an exhaust brake with your Screamer turbo buy according to the year of truck; see optional accessories section for year ranges and part numbers for BD Diesel exhaust brakes.

Introduction

The BD Screamer turbo series is now available for the 2003-2007 Dodge 5.9L Cummins. The Screamer turbo is designed to be a drop-in stock-appearing performance turbocharger that increases boost, decreases drive pressure, and peak EGTs without affecting low-end drivability.

The 5.9L Cummins screamer turbo utilizes 63mm billet compressor wheel and a 67mm high-flow turbine wheel which offers increased turbine flow and efficiency. The screamer is capable of increasing horse power by 100whp over a stock turbo, and with supporting modification it is capable of 625hp.

Tools Required for Installation
