Turbo Comparisons

When in the process of bombing a CTD you will have to increase your fuel. With the increase of fuel comes an increase in heat. You can safely run 1200° once in a while but major failure can occur if your running at high heat conditions for a period of time. To keep things cooled […]

Replacing Front Spring Bushings on a Ford Pickup

The factory Ford rubber spring bushings just didn’t last on my F-350, due in part to the heavy Power Stroke engine. The best replacement for these are urethane bushings. They last much longer and can come embedded with graphite for lubrication to eliminate squeaking. The best manufacturer of these urethane bushings is Energy Suspensions.  I […]

Why the Big Change?

It has been two years – sorry for the long delay in getting the site back up. We changed our minds several times on how we were going to rebuild – the rest of the time, we were just too darn busy. The old DieselDatabase.com sites revolved around aliased URLs (cumminsdatabase.com, powerstrokedatabase.com, duramaxdatabase.com, peterbiltdatabase.com, and […]

Exhaust Stacks

I built this setup from scratch and ran it for only 1 month before removing and reinstalling my 4″ system. This system sounded very good but had some draw backs that I couldn’t live with including noise and smoke for passengers in the back and soot showers on startup after a rain or carwash (there […]

Velvet Ride Shackles

Velvet Ride Shackles, made by BF Goodrich Aerospace, are designed to replace the rear spring shackle, and create a more comfortable, less buck-board feel ride by absorbing some of the harsh bouncing of the stiff heavy duty springs. They basically use a rubber torsion device inside of the shackle.  I bought mine from 4 Wheel […]

On Board Air Tank

It’s always handy to have compressed air with you for filling your flat tires, other people’s flat tires, air horns, blowing mulch or straw out of your bed, the list can go on and on.  I use compressed air mainly for my air horns. I’ve had a 9 gallon air tank in my aluminum bed […]

Here is a schematic drawing showing how to wire it. Using the above circuit, adjusting the potentiometer adds resistance to […]
