Diesel Mechanic reviews the 2024 Chevy 2500 with the new Duramax Diesel second gen L5P Engine and discuss all the mechanical upgrades, benefits, fuel economy and added power this new duramax diesel engine is putting out 470 horsepower and 975 lb-ft of torque. It seems like GM was trying to add efficiency to this engine to increase power and probably more importantly Decrease Emissions. which can be so critical on these modern diesel engines.

I was very excited to get my hands on this new L5P 2024 Duramax diesel engine. Today as I mentioned I was going to discuss all the upgrades GM gave to this engine in order to make that extra power and max towing numbers.

the first upgrade is on the fueling system. this new duramax diesel can now put out a max injection pressure of 32,000 psi which is an increase of about 3,000 psi. more pressure means the diesel fuel will be atomized better meaning the diesel fuel will burn more efficiently, resulting in more power and less emission created.

along with higher fuel pressurs are reinforced high pressure fuel rails and updated injectors with slightly different nozle spray patterns for once again more efficiency and better burning of the diesel fuel.

this new duramax engine is also coming with upgraded pistons. these new pistons are a much more aggressive style of piston with a raised center cone which allows for better fuel air mixture and once again more efficiency. leading to great power numbers and less emission created.

GM has updated the cylinder heads with more cooling to keep the combustion chamber cooler and to dissipate heat much better which will put less stress on the cooling system. a cooler engine can simply run longer with less issues.

gm also updated the head gasket to make it a much stronger unit which I like to see on this powerful Duramax engine.

The exhaust brake on this engine has also been improved which I really think needed to be done. the 6.7L powerstroke and the 6.7L cummins engines have much better exhaust engine brakes and its nice to see GM address this. they added 20% stiffer exhaust valve springs to help allow the VGT turbo to create more back pressure and slow the truck and trailer down more aggressively.

lastly GM put a brand new Turbo on this engine. it is slightly bigger but most importantly is the updated electronic VGT actuator which controls the speed of the turbo. a quicker VGT allows for better throttle response and just a better performing turbo and engine. so I really like this upgrade as well.

the max towing capacities have all been increased as well pushing an extra 3,000lbs of towing capacity so hopefully this 2024 Duramax will have a better performance on my towing loop!

Lastly I think GM has put this Duramax engine in a very nice place in the HD truck segment, I also touch on how Ram 2500's cummins are a little outdated and need to change something to be more competitive in the HD truck market.

Hope you guys like the video!
