Dodge Cummins Diesel Ram 2004.5-07
Recipe For Horsepower


We get a lot of calls asking, "What do I need to do to my truck to attain a certain horsepower level?"  We thought we would throw out a few rough guidelines to help you out when you are shopping for parts.  We are doing this section specifically for the 04.5-07 5.9L Dodge Cummins so it's not a generic model.  Some of the recommendations will be a little vague.  We are going to try and lay out the best way to make the stated horsepower rating.

For example, you could grab the highest setting on your programmer to make 500HP on a dyno run but for longevity you would be better off with a set of 50HP Injectors and a lower setting on the tuner.  We are going to mention a lot of specific products.  These are products that we prefer through our experience.  There are, of course, many other options that we have available on the site. 

Bear in mind that even though Dodge says your truck is 325HP they are quoting flywheel horsepower, not rear wheel horsepower.  On a dyno, the actual rear wheel horsepower for these trucks is about 270HP.  Please don't get sucked into the trap of adding all of the manufacturer stated horsepower gains for the individual products together to estimate your horsepower.  This will only lead to disappointment!
