fjh Posted October 20, 2022 Share Posted October 20, 2022 I would be interested to hear everyone's comments on the above subject! The first of many of my thoughts would be replacing the fuel system with a proper HPCR system Bosch type system! the Engine mounts would be high on my list as well! 1 1 Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted October 20, 2022 Share Posted October 20, 2022 (edited) Yes! This will be fun. Let me make a list I be back later Edited October 20, 2022 by Onyx610 Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted October 20, 2022 Share Posted October 20, 2022 For starters, the rear mounted gear train. Quote Link to comment Share on other sites More sharing options...
Mackpro Posted October 20, 2022 Share Posted October 20, 2022 As FJH said , a true high pressure common rail fuel system. Put the high pressure pump where the optional REPTO PTO goes as I rarely see this used. Make the EGR valve and cooler easier to remove/replace. A separate air filter for the AHI as no one changes their air drier cartridge anymore and this the cause of 90% of AHI failures. More/better insulation on the chassis wiring harness. Re-program to where the engine won’t won’t derate when a ABS fault occurs. Quote Link to comment Share on other sites More sharing options...
Popular Post High Binder Posted October 20, 2022 Popular Post Share Posted October 20, 2022 One of my pet peeves is that the truck designers and engineers should have to turn wrenches for two years before they would be allowed to design or engineer anything. 3 2 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted October 20, 2022 Share Posted October 20, 2022 go back to the CL-713 with an E-Tech 460 XT, and 13 or 18 speed Maxitorque, 200series carriers 4.42:1.... and I guess the option to have M-Ride if you dont like camelback... Damn you Onyx... as for the Highway, CX-613 E-Tech 400 or 454, 10 speed or 13 speed Eaton, and Eaton 404/405 rears maybe 3.72 or 3.90:1...... I like to be able to repair them without re-financing my life with the Devil to do it. jojo 😈 1 1 Quote Link to comment Share on other sites More sharing options...

Makes It much easier to work on in COE trucks.. All the euro Engines are like It..

Onyx610 Posted October 20, 2022 Share Posted October 20, 2022 But Mack doesn’t make a cab over and I live in the United States 😃 My solution to that would be the Volvo engines can have the rear mounted timing gears and the Mack gets front. Or all US engines get front mount and all Euro get Rear. Cummins doesn’t do it that way and I’m pretty sure they are all over Europe. 1 Quote Link to comment Share on other sites More sharing options...

Onyx610 Posted October 20, 2022 Share Posted October 20, 2022 So i know this hasn’t been up to long, but its starting to look like this engine really isn’t as bad as people make it out to be. When the only real issue seems to be the fuel system. Quote Link to comment Share on other sites More sharing options...

When the only real issue seems to be the fuel system. Correct ! These mp engines would have a lot less problems had they gone to a proper common rail system! The dollar store Delfy system only half fixed the injectors dancing in the cups! In my opinion the egr valve mounted on the cold side of the cooler would help to! 2 Quote Link to comment Share on other sites More sharing options...

Do you see the three electrical fired one’s failing ? The ones that fail now are the plunger operated ones! Correct? 1 Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted October 21, 2022 Share Posted October 21, 2022 Yea good point, if they could get a legit high pressure pump they could pry do away with the unit pump injectors. That would be kind of going back to your guys first idea. Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted October 21, 2022 Share Posted October 21, 2022 If we start seeing changes in the next couple of years, we know vovlo is watching us haha.
