This is the stuff your truck’s air filter is supposed to keep out of the engine. What you see here is a pile of ISO 5011 test dirt that is weighed before it’s sprayed onto an air filter to test efficiency.
Myth-Busting the Science of Airflow and Filtration
Opinions are like bellybuttons … everybody has one, and they are all different. When the topic of automotive air intakes, airflow and filtration hits the Internet diesel forums, that analogy comes to mind.
So how can you separate the BS from the real deal when it comes to understanding what your diesel needs in terms of airflow and filtration? Even the aftermarket companies tell different stories. (more…)

The Sigma Short Shift kit from dieselgeek.com is a billet aluminum replacement for the stock shifter.
We specifically purchased a manual transmission-equipped TDI for the strength and reliability over their automatic counterparts, but that doesn’t mean there is no room for improvement. To many VW drivers (including us), the long shift throws from the factory setup seem like they would be better suited for a domestic truck than a German sport sedan. (more…)

BD Power’s Direct Replacement for the 7.3L
Nearly 10 years after its demise, the 7.3L Power Stroke is still one of the most sought-after diesel powerplants. The 1994-2003 Ford Power Stroke was the most popular light-duty diesel ever produced, and with new truck prices cresting over the $50,000 range, more and more owners are willing to invest a little money into those old 7.3L trucks to improve their overall performance and efficiency.

Lots of Ford lovers say that the ’94-’97-model Power Strokes were the last diesel trucks from Ford with character.
Driven Diesel’s New Regulated Return for the ’94-’97 Power Stroke
Among Ford purists, the last great Ford diesel truck ever produced with any styling character was the old body-style (OBS) Power Stroke.
These round-nosed beauties were the predecessors of the Super Duty and are fitted with a similar version of the 7.3L Power Stroke that eventually ended up between the fenders of the Super Duty. (more…)

Here’s our little VW TDI trying to “roll some coal!” There was definitely more smoke on both of the Kerma TDI tunes.
To further enhance the power and performance of our Jetta, Matt Ford (the “MF” in MF Automotive) used a KermaWare Q Loader to flash our engine ECU with a tune programmed to give us more torque and horsepower. After downloading our original factory tune to the Q Loader, it is emailed to Kerma TDI, where a custom tune is written and e-mailed back and then installed in the car with the Q Loader. We received a low-smoke tune, as well as a modified tune, for our engine. When we drove the car on the stock tune, it seemed as if the new Stage 1 Colt camshaft gave us a very modest bump in low rpm performance, but when the tunes were installed, the car really woke up—with a significant boost in torque and horsepower that could be felt from the driver’s seat.

Adding Reliability and Performance
Knowing in advance of the propensity for pump deuce TDI engines, such as the 1.9 L mill in our ’06 VW Jetta TDI, to have cam wear issues, we planned to tackle the cam and timing belt replacement right away. But, before we tore into the engine and started modifying, we thought it would be best to strap it down to the Dyno Dynamics chassis dyno at Bean’s Diesel Performance to get baseline measurements.

Diesel World’s latest project truck is this clean 2006 Ford Super Duty.
Souping Up a Super Duty
There’s no question that the economy has put the brakes on new diesel sales—unless you’re Donald Trump and can afford a $50,000 to $60,000 pickup.
That leaves the used market wide open for the pickin’. Diesel enthusiasts are flocking toward used trucks for a variety of reasons, including a lower purchase price and the fact that with the money you save from NOT buying a new one, you can customized your rig to fit your needs and tastes. (more…)

In the diesel performance world, O-ringing or fire-ringing the heads is a very common upgrade. Common, because, in high output situations, it’s all that will keep the fire contained in the combustion chamber when pressure is trying to launch the cylinder head into low synchronous orbit. (more…)
