Is the LMM a good motor?
Consistent to its very similar LBZ counterpart, the LMM is a highly reliable engine. The DPF is a hot-spot for failure so beware that you will probably end up with a few thousand dollars of DPF/emissions repairs, however you can *illegaly* remove this potential problem by removing the DPF system.
What is the difference between LBZ and LMM?
Over all there is little difference between the the LMM and LBZ. LMM has additional emission plus an air intake valve but other than that not a big difference. Stock mine does 18mpg on the highway I have seen a little over 21mpg with some of Nicks tuning. I seldom use that tuning though.
How much HP can a LMM handle?
As we’ve mentioned, some LBZ and LMM pistons survive 700 or more horsepower while others bite the dust at 600.
What’s better LMM or LBZ?
LBZ does not have DPF so no urea tank to fill. LMM does have DPF. Thats the main big difference other than the body style change. DPF kills the mileage and performace on the LMM, but you can delete the dpf which is illegal but if you know someone that will pass it for inspection you will be fine.
How can you tell the difference between LLY and LBZ?
The simplest way to tell the lly or lbz is the dished valve cover. You should be able to see the valve cover is dished around the injector. Custom 12x12x2 Oil cooler and transmission cooler, Custom Cold side IC pipe, Enabled 6th gear.
How much HP can a L5P handle?
For reference, the 6.6L V8 L5P Duramax engine is rated at 445 horsepower at 2,800 rpm and 910 pound-feet of torque at 1,600 rpm from the factory. The engine is only available in the current Chevrolet Silverado HD and GMC Sierra HD, where it is paired with an Allison-branded 10-speed automatic.
What’s better LLY or LB7?
The LB7 was the simplest in terms of emissions controls, while the LLY came with the largest turbocharger ever offered. The LML brought higher fuel pressure, cleaner emissions and nearly 400hp into the equation, while the current L5P upped the ante even further and has 600rwhp potential in ’17-newer GM trucks.
