Straydog954 Posted July 3, 2023 Share Posted July 3, 2023 Anybody have any thoughts on this engine good or bad regarding performance and reliability? It has no dpf Quote Link to comment Share on other sites More sharing options...
Mackpro Posted July 3, 2023 Share Posted July 3, 2023 For on road use in a CXP the 405 HP rating is best. In dump truck/logging off road use the 395 HP version is better (CTP). The turbo, EGR valve and EGR cooler are very specific to this year model engine. The EGR mass flow and temp sensor assembly is a shortened version from the ETECH ASET AC engine and prone to failure. Almost every CXP/CTP I ever plugged my laptop had active codes for this sensor. However people run them all the time like this. These engines came with copper injector cups and flat bottom injectors. There is no upgrade option to stainless cups/conical injectors for this engine like there is for the 2008 and up engines . Lots of Service bulletins on these engine for updated parts. All this sounds bad but actually they are pretty reliable. Local guy here has 8 or more of the CTP’s and they run every day. Quote Link to comment Share on other sites More sharing options...

In comparison to my em7-300 fully mechanical, how would this engine rate ? Mine starts pulling around 900 rpm. Is this a high torque at low rpm engine or does it need revs ?

Mackpro Posted July 3, 2023 Share Posted July 3, 2023 Can remember for sure on peak torque rpms but the 395 has 100 mor foot pounds of torque than the 405. A lot of guys had their 395’s bumped to 405 only to regret it and then had it set back to 395. Quote Link to comment Share on other sites More sharing options...
Mark T Posted July 3, 2023 Share Posted July 3, 2023 The MP 7 you ask about would clean the EM7 300's clock (in my opinion) These don't have the wallop of an old 400 HP 3406 or anything like that, but if they're in good shape ???? they're a good engine. Mackpro pretty much described it as well as could be described . Quote Link to comment Share on other sites More sharing options...
