Load Dyno vs Inertia Dyno
There are two main types of chassis dynamometers for measuring your truck’s power – inertia dynos and load dynos.
As the name indicates, an inertia dyno measures horsepower with inertia, or the velocity of a fixed mass (the rollers). So, the faster a truck can accelerate the rollers, the more power it has. Then, torque is displayed as a calculation from the horsepower figures (Torque = Horsepower X 5252 / RPM). Since inertia dynos are a somewhat simple design they are often less expensive, and thusly more common.
The second type of dyno is a load bearing dyno. Continue reading
Oiled Filter vs. Dry Filter for Duramax
When ordering an intake for a Duramax, we often get the question about what is the best air filter for a Duramax…an oiled filter or a dry filter. On the Duramax intake, there is a MAF (mass air flow) sensor that is located on the intake just past the inlet filter. This sensor is there to read the amount of air flow that is passing through the intake. It uses this information to properly fuel the truck. The more air flow, the more fuel, etc.
These sensors are extremely sensitive and the slightest amount of dirt, dust, or oil can cause them to not function properly, affecting mileage, performance, spool-up, and more. Continue reading
Understanding the How and Why of a Lift Pump System
Our modern diesel pickups have changed and improved drastically in technology since they were first introduced in the 1980s. We now have variable vane turbos, six-speed automatic transmissions, piezo injectors, and the list goes on. However, even in these modern diesels, there are aftermarket options available to help improve the performance of these trucks.
One of the first modifications to consider on your diesel is adding some type of fuel system assistance like an Air Separator Lift Pump System.
What Does A Lift Pump Do?
Some of you might be familiar with the term lift pump because it’s a common upgrade for most diesel pickups. A lift pump assists or pumps more fuel to your injection system which is beneficial when creating more power, but an Air Separator System does more than just that.
Use Auto Detailing Clay to Spruce Up Your Vehicle’s Paint
The paint surface of your vehicle is under assault every time it is out in the environment. Brake dust, industrial fallout, tar, sap, roadway debris, winter road spray, airborne pollution and even tiny metal particles all eventually take a toll on your vehicle’s paint. Consider Detailing Clay to give your vehicle a new look and new life!
If you haven’t heard of detailing clay before or haven’t ever used it, chances are that you need it. Over time many or all of these tiny particles become lodged in the clear coat of your paint, not only making the appearance of the paint job look bad, but possibly leading to paint failure.

Compound Turbos Explained
There is a lot of misleading information out about compound turbo boost numbers. Many think the high pressure turbo (secondary) boost number can be determined by just subtracting primary turbo boost from overall boost. This is NOT the case.
To figure out how much work each charger is doing, you need to convert to pressure ratios (P/R) first. The correct pressure ratio formula to use is: Continue reading
