My buddy with the motorhome would like to do some "BOMB'S". ;D... What kind of injector's would work best? We are going to put 4" exhuast straight, and modify the air intake. Any help would be greatfull!

 

what year engine? 12v or 24v.<br>DM01

 

Sorry it took so long. Here is the info on his eng.<br><br>91' cummins B series 12v (ser# 44602854)<br>Tranny 4-spd Auto Allison (model# AT542)<br><br>As stated before, we are going to put a 4&quot; exhaust and modify the air intake system. What else can we do to bump the HP up some? And will the scotty II air system work on this application? Thanks for the info.

 

Looks like the 160HP/400TQ engine. Interesting that the motorhome engines could have either the VE distributor pump or the &quot;P&quot; type in line pump depending on exactly when Cummins began the switch or what the manufacturer specified.<br><br>Larger injectors would be a good start as well as a TQ plate if you have the &quot;P&quot; pump. <br><br>Don~<br>
