Nick Priegnitz of DuramaxTuner.com walks through the air flow of the 2017 + L5P Duramax. He walks through the EGR, up-pipes, M-pipe or y-bridge, and of course does a complete tear down of the L5P turbo charger.

Thanks for another great video Nick! Between DuramaxTuner and Gale Banks, I think I’ll be buying an L5P in the coming years. Seems like a reliable platform so far compared to the LML. Hopefully the tuning and deleting process will get simpler and more cost effective as the aftermarket releases more and more products for these things!

You said the limitation is the heat so safe is roughly 550 could you push the turbo more with the cat deleted
@Duramaxtuner5 жыл бұрын
The "cat" or DOC is not the limiting factor to the turbo. At least at this point we don't believe it is. More than likely the small compressor wheel and turbine wheel are going to limit how efficiently the turbo can make cold air.

@@3DProductions well the SCR is mounted to the back of the turbo (we did a L5P turbo review you can watch) so that takes a several hours to remove the turbo, most people with a $60K + truck prefer to a really nice EGR delete which is a lot more than a few block off plates, and the cost of L5P Tuning is (for delete or non delete) over $4,500 without core charges. Due to EPA restrictions we do not offer any deletes. The LML is still a strong platform that is going to fit a lot of peoples needs. For those with an L5P that would prefer to keep their emissions equipment intact and still want all the benefits of tuning, we can help.

I've noticed every time I shut my L5P off, the veins open and close about 4 times...wonder if GM did that to keep veins from sticking. My LBZ would often throw a code for the vein position sensor.

@Dobbies Revenge If your truck is just a daily driver it comes down to preference. Most people will tell you that ownership cost of a diesel is a little higher than an equivalent gas truck. However, if you want gobs of low end torque and a potential for a 500+ RWHP truck the diesel is going to be for you.

I know this is an older video, but you state the factory egt cut is 1530f. I don't believe that to be the case, I'm pretty sure it's 1471f. I know it doesn't sound like much but a material engineer will be able to tell you how much percentage strength your losing and why the factory calibration cuts fuel at anything over that temp.

1530 is the shut down temp on these trucks? That seems to be extremely high considering I set my defueling on my truck at 1250-1350. Whenever people ask what is safe these are the temps I tell them to keep in mind. Are these higher temps around 1500 still considered safe?
@TheMEXICANBEEF5 жыл бұрын
Great questions. Is the 1530 the limp mode temp, or is that when the computer starts defueling? I would like to know when heat soak becomes a problem. I've always been told to keep my 04 cummins under 1300 while towing or stuff can begin to melt. I would be very impressed if these new duramax engines can withstand 1500* towing temps.

Just to be clear though, our Custom Tuning is very different than a wired in external module. We are able to include a much higher peak horsepower and torque output that is made capable by our extensive ECM/TCM mapping.

Not sure about the “hard science” but I would think it would cool the combustion chamber immensely compared to using exhaust. Plus, you do not kill power with exhaust. Also, the water/meth would help clean the exhaust system. I have been thinking about this for a while now, Ha!

Correct, 570 with an all stock truck has been hit but the EGTs and other indicators were well past safe (at least in all of our testing). As far as why GM doesn't go to reverse flow heads, our guess is that they don't see a need for more than 500 RWHP.
