Everybody loves boost. The higher that gauge climbs, the better, right? Well, not exactly.

This week on the Power Driven Podcast, Will and the guys get into one of the most argued topics in diesel performance. Boost. What it actually means, why more of it doesn't always equal more power, and where the whole "boost is just a measurement of restriction" idea even came from.

The conversation started after a buddy rolled in from Washington with a 6.0 Power Stroke on one of their new 68mm GT turbos. The thing laid down 662 horsepower to the wheels on completely stock heads and a stock intake. At only 33 pounds of boost. Meanwhile builds running 45 to 50 pounds are struggling to match that number. So what gives?

Turns out the number on your boost gauge is only part of the story. What's happening on the exhaust side, how well your cylinder heads flow, your intercooler efficiency, air density, exhaust back pressure, all of it plays into how much power actually makes it to the tire. The guys break all of that down in a way that actually makes sense whether you're building a diesel drag truck, a tow rig, or just trying to get more out of your daily driver.

They also get into why diesel turbo technology has quietly lapped the gas performance world, the real reason gasoline engines can make insane power at lower boost, and the tuning strategy behind the Junker's 1,170 horsepower 12 valve build.

Plus the age old turbo sizing debate, why chasing peak dyno numbers can actually ruin a truck, and why the best feeling diesel you've ever driven probably wasn't the highest horsepower one.

You don't feel a horsepower number. You feel fun.
