Compression brake in 5.9?

[Dan Simmonds]

Does anyone know if a compression engine brake (as opposed to an exhaust brake) was ever designed for the 5. 9L engine... . or if a compression brake could even be fitted to an existing highway-use 5. 9?

FAQ7:

Will there be a Jacobs Engine Brake for the Cummins B or C engines?

ANSWER:

Jacobs Vehicle Systems is not developing an Engine Brake for these engines today. Typically engine brakes are applied to engines of 10. 0-L displacement and higher. The Jacobs exhaust brake product is available for the Cummins B5. 9, ISB, C8. 3 and ISC engines.
