How to Roll Coal


Hey Everyone,
My friend and I were having a debate about "rolling" coal the other day. I personally hate guys who do it because I feel like it puts a bad out a bad rep for all of us diesel owners who use them for what they really are, not just to show off. Well this question isn't how to make your truck smoke in terms of mods, it's how to actually physically do it. My truck has only ever smoked a little when I'm pulling a heavy load and lugging. I drive a 5 speed by the way. So I told him I think it's only done by lugging. He says the opposite, that people smoke the most at high RPM's.
I was just curious who was right? I always thought that at higher RPM's the turbo spooled and got rid of the smoke. I figured that if I tried to start out of third gear and was flooring it that that would be how to physically make it smoke.
Thanks for any input.

Smoke equals lots of fuel with little to no air or not enough air. It can be through out the fuel curve.

Sweet! Thank you, that's exactly what I was looking for. I knew that the more throttle you give it the more fuel you're injecting into the cylinder, which is why I figured it'd be at a lower RPM when the turbo isn't sucking in a ton of air to clean it up. Thanks for the info!

If you actually read my initial post, I said I hate people who do that. So before you throw out accusations accusing me of wanting to be one of those douche bag "bro" type guys in their street queens, I'd suggest reading the whole post first. I asked solely for informational sake, to tell my friend I was right.

Can you roll Coal in a stock diesel?

No matter how modified a gasoline engine is, it isn't going to work. The smoke is the result of unburned fuel particles, and only diesel will do. Gasoline isn't dark or thick or offensive enough. But not just any diesel truck can roll coal.

What causes diesels to roll coal?

Rolling coal is a term used to describe when a diesel engine is overfueled to the point that opaque black smoke comes out of the exhaust system. Diesel Power Editor KJ Jones describes it like this: "Generating severe 'black smoke' with diesels is, for all intents and purposes, a direct by-product of excessive fueling.

How much power can a 7.3 make?
