Project Box Hauler: Dynomite Injector Install

The Injection Connection
Project Box Hauler Gets New Dynomite Diesel Performance Injectors

For those of you who have been following our Project Box Hauler series, you’ll remember our high-miler, ’01 Ford F-350 dually with 200,000-plus miles on it, was diagnosed with a couple of dead cylinders, more specifically No. 3 and No. 8. Upon his initial diagnosis, Nate Brekken at Strictly Diesel in Scottsdale, Ariz., guessed the problem would more than likely be bad injectors on those cylinders since injectors get fairly tired and worn out on the 7.3s after about 150,000 miles. On the other hand, two dead holes could mean more serious issues, such as bad valves or poor compression from worn-out piston rings, or even a cracked cylinder head.

Here’s the complete set of Diesel Rx 7.3L Power Stroke glow plugs. Note the tips are slightly discolored from testing.

Installing New Glow Plugs Will Fix Cold Start Woes

Since diesels are compression-ignition engines, meaning there are no spark plugs to start the combustion process, nearly every diesel is equipped with some sort of glow plug system to get the fire started in cold weather. The little “Wait to Start” light that comes on usually indicates that the factory glow plug system is activated as part of the cold start circuit. Today’s computer-controlled engines have taken the glow plug system engagement to an all-new level, taking into account the various engine parameters as to when the glow plugs will be activated or not.

Project Box Hauler: Intake and Exhaust

Saturday, July 17th, 2010

The Huspower 4-inch, turbo-back exhaust system was the perfect upgrade to improve the breathing on Project Box Hauler project. The system comes complete with all the necessary hardware and brackets along with a 5-inch polished stainless steel tip.

Another area the stock 7.3L falls short in is the factory exhaust system. The 3-inch system is necked down just past the turbo outlet and continues on a kinky path to a chambered muffler, which robs even more performance. So improving on things is fairly easy with a quality turbo-back system since there’s now catalytic converter on this truck.

Project Box Hauler: Part II

Friday, July 16th, 2010


Project Box Hauler is just that…a box hauler. The truck spent most of its life as a Castrol Racing show car hauler, racking up well over 200,000 miles.

Part II: Bellows Style Up-Pipe Upgrade

Last month, we introduced our latest project truck, a well-worn, 200,000-plus–mile Ford F-350 fitted with the 7.3L Power Stroke and a six-speed manual transmission. The owner found this dually while scanning the classifieds where it was listed for sale with a 28-foot gooseneck trailer. The combo used to be a Castrol Racing/John Force car hauler that racked up 215,000 miles in regular cross-country jaunts.

Part I: What to Expect When Buying a Used Diesel

If anything positive has come from the latest economic downturn in the United States, it’s that Americans are relearning the value of the dollar. According to recent surveys, Americans are putting away more money now than in the past 20 years, and people are looking more closely at monthly spending than ever before. While the credit crunch has put the hurt on new truck sales, more and more diesel enthusiasts are fixing up and updating the vehicle they current own rather than create huge debt by buying new.
