I need to put an exaust system on a detroit 671. One guy says it needs a straight flow through muffler. One fellow says it needs back preasure. Can someone clear this up for me. |

Thanks Marv,
I will be using it to power a sawmill. It was used as a stand-by generator for a large factory. The engines (2 of them) are to run at 1800 rpms. They drive a gearbox that reduces the rpms to 1200 for the generator. I need that speed to achive the 60 cyl. 480 volts.I hope this helps with the back pressure calculations.

AT 1800 RPM YOU SHOULD HAVE 3.3 B/P, AT F/L. EACH ENGINE NEEDS IT OWN EHAUST SYSTEM. HOPE THIS HELPS |
