How much HP can Allison 1000?
As you’ve probably deduced up to this point, the stock Allison will handle roughly 350 to 400-rwhp in five-speed form and 425 to 450-rwhp in six-speed trim. However, if you push things past that point the clutches will eventually slip and bring on the Allison’s notorious “limp mode” condition (i.e. limp home mode).
Is a 6.6 diesel any good?
The 6.6L Duramax has been in production since 2001 and has proved, on a large scale, to be a relatively reliable and durable platform. However, like any engine (or any complex mechanism for that matter), the Duramax engine and Allison 1000 transmission have some common problems inherent to their design.
What is better LB7 or lly?
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.

How hard is it to change LLY injectors?
It’s not very difficult. Make sure you get new seals and coppers, and make sure that the injector bore is clean before you install the new injector. All the injectors come out the easiest if you remove the line first. Use a screwdriver or similar tool to pry up on the hold down and just wiggle the injector up.
When did the Duramax 6.6L turbo diesel come out?
The Duramax 6.6L V8 turbo-diesel engine is nearing its 20th year of production, after debuting in 2001. Over the engine’s lifespan it has gone through 6 different engine variations: LB7, LLY, LBZ, LMM, LML, and L5P.
Is the LMM engine the same as the LBZ?
The LMM is virtually the same engine as the LBZ with more emissions control. The LMM features a diesel particulate filter (DPF), an oxidation catalyst, and a more savvy EGR. DPF’s essentially capture and hold any leftover diesel particulate, preventing it from being released into the atmosphere.
How big is a 6.6 liter diesel engine?
Displacing 6.6 liters in a V8 configuration, the LML is part of the Duramax family of heavy-duty workhorse engines. With nearly 1.3 million Duramax diesel engines in operation no other automaker has as much diesel engine development experience in meeting the demands of the heavy-duty truck customer as General Motors.
What kind of fuel injector does a LMM have?
Another refined bit of hardware featured on the LMM is a revised fuel injector design. While the LBZ was equipped with a 7-hole, 158-degree injector nozzle, the LMM returned to a 6-hole nozzle design with a 159-degree range.
