EdwinDHershey Report post Posted January 31, 2017 I have a 2001 Monaco Knight with a Cummins ISB 5.9. Looking to get a little more HP to help pull Mts out West this year. I'm looking to replace the stock radiator cooling fan with a Source Engineering fan blade. There are saying around 33hp increase and 50% less noise. Any feedback would be helpful.

manholt Report post Posted January 31, 2017 Ed. Per Cummins, I could have added HP to the engine I have, but then I also would have to re configure the gear change points in my Allison 3000...that costs some serious money! There are several posts on this subject on this Forum under Engines. look at 2014 and work your way up...it's an eye opener! Carl Share this post Link to post Share on other sites
wolfe10 Report post Posted January 31, 2017 The Source Engineering Fan is not an engine modification. It is just a different fan for rear radiator coaches that takes less HP to run. No changes to engine or transmission needed. http://sourcerv.com/fan_blades Share this post Link to post Share on other sites
manholt Report post Posted February 1, 2017 Got it, it doesn't add more HP, just uses less HP from what's available, that is more HP to drive axel from what you have now! Would be nice to have that for a side radiator! Carl Share this post Link to post Share on other sites
EdwinDHershey Report post Posted February 1, 2017 The gentleman I talked to at SEF did say a savings of HP to drive the fan not gaining 33HP, But that seems like it would make a nice performance difference. He also said I might see a difference in Exhaust brake performance since the stock fan would I guess have more resistance to help slow down. I'll keep checking this post. Thanks for your input.

EdwinDHershey Report post Posted February 1, 2017 Ok. This might be a Spring project when it warms up here in Pa. I'm now getting ready to have a Fasspump installed to prevent a VP44 injector pump failure down the road. Still researching between Fass or Airdog. Thanks for your help..

I did the Airdog system with the filters and its own return line to the tank. I also changed the vp44 pump because the new to me coach had been run without the stock lift pump and it didn't perform as it should. Share this post Link to post Share on other sites
