Exhausting Emissions Questions
It’s kind of funny because 20 years ago, no one wanted a clacking bucket of bolts, let alone have to work on one of these diesel engines. That was simply how the diesel engine was viewed. Now, mid-size trucks offer reliable power, awesome torque, quiet engines and decent fuel economy from a vehicle that can
High Performance Diesel Market Includes?Growing Number of Parts
In many cases, the diesel engine is taking over the hot rod world. Instead of a small block or big block Chevy in the classic cruiser, people are looking at the Duramax diesel. The same goes for the Ford engines being replaced by the Powerstroke and the Dodge being substituted with the Cummins. The desire
Updating The Late Model Hemi
At the time of our build a new 6.1L was around $1,000 from Mopar. This is definitely reasonably priced but we really planned to stick to a budget and did not know what we would be up against. One thing that really threw a wrench into things was – just for giggles – we entered

Being in the diesel business the one complaint I hear most often from diesel owners is the famous question, “Why is diesel fuel so expensive?” After all, diesel fuel is not as high up the refinement ladder as gasoline. Consumers understand this and often wonder why there is a difference in price. The question can
Understanding Port Swirl In Diesel Engines
What is port swirl? Actually this is a little contradictive. The port doesn’t actually swirl, it is the design of the port that causes air to swirl! Swirl is what is taking place when the intake charge exits the intake valve and enters the combustion chamber. As the air enters the combustion chamber and the

Understanding The Mysteries Built Into The Ford Power Stroke Engine
After servicing and answering questions about these engines for several years, it finally occurred to me that the owners of these engines didn’t understand how they work – and, frankly, neither did many repair techs. I remember when Ford introduced the Navistar engine in the middle of 1994. The rumor on the block was that
