Show Notes
Todd, Will, and Myer sit down to build the ultimate 1000 horsepower Cummins street truck from the ground up, part by part. Five hundred horsepower used to be the number that turned heads. Now the bar has moved, and this episode lays out exactly what it takes to build a diesel truck that lives at four digits and still drives home every night.
The guys pick a 2006 third gen Dodge with a 5.9 Cummins as the starting platform and spend real time weighing that against stepping up to a 6.7 Cummins, covering spool, towing manners, and how each block handles the power level. If you're deciding between a 5.9 and a 6.7 for your own diesel truck build, this breakdown will save you a lot of guessing.
From there the conversation moves into turbos, comparing the factory 8351CW against aftermarket compound setups built around an S466, S467, and a 98 millimeter atmosphere charger. They talk through single turbo versus compound turbo tradeoffs, when a wastegate actually matters at this power level, and how compressor and turbine sizing changes spool and peak power on the dyno.
They cover the bottom end and cylinder head next, going over street fighter connecting rods, 14 millimeter main studs, and the ongoing debate between H, P, and V bearings for a truck that sees real street miles. On top of the block, they break down cylinder head stages, valve springs, pushrods, and when a bigger intercooler actually becomes necessary as boost climbs.
Fueling gets plenty of attention too, with a look at CP3 pumps, single versus dual injector setups in 12 and 14 millimeter sizes, lift pump options like Air Dog and Fleece, and why upgrading your rail pressure sensor and relief valve matters once you push past factory pressure.

Single turbo or compound turbo: which one really makes more horsepower? This episode started with a comment from viewer @V8Lenny (youtube.com/@V8Lenny) claiming a single turbo will always make more power than the same charger run in compounds, so we put that claim up against years of diesel dyno numbers and real Cummins builds.
What happens when an $11,000 VP44 Cummins with a short parts list out tow trucks that cost five times as much? Willard, our 2001 Dodge Ram dually, just pulled a race trailer home from Diesels in the Mountains and held the speed limit up the grades. This episode breaks down why this old 24 valve keeps surprising everybody and what it takes to turn a 25 year old diesel truck into a legit cross country tow rig.
A shelf on cylinder head just won the biggest payday in diesel drag racing, and it beat trucks running heads that flow a lot more air. If you think bigger is always better on a race build, this episode of the Power Driven Podcast might make you rethink your whole combo.
What does it actually take to keep a Cummins alive past 3,000 horsepower on the dyno? It is not just more fuel and a bigger nitrous shot. This episode breaks down the real engineering behind Myer's second gen common rail race truck and why so many mega power builds scatter before the pull is over.
Every diesel guy has a list of mods he would take back, and in this episode Todd, Will, and Myer own up to theirs. From pushrods that snapped on a tow to Texas to a 12 valve Cummins quietly running out of oil, this is a shop floor confession about diesel truck mistakes that cost real time and money, and how to avoid repeating them on your own build.
