1200+ hp / 2100+ lbs-ft

Didn't get to make it this year, but here is an article about this years diesel finals in Ennis, Tx.

THE GRAND FINALE: 2017 NHRDA WORLD FINALS

My neighbor was the first to break into the 9's with stock long block 5.9 Cummmins in a street legal 2nd gen RAM.

Project Rust Bucket made over 900RWHP with an untouched factory bottom end.

How much of that 6.0 was OE?

To be fair the 6.7L Cummins in Lavin Miller's truck, the first person to win back to back Diesel Power Challenges, had a lot of aftermarket parts as well. Althouh the Cummins truck that he competes with now, which is currently the quickest in the diesel Pro Street class and won the 2017 Ultimate Callout Challenge with, would have easily won the 2016 and 2017 Diesel Power Challenges. However, the challengers are limited to two years of competition.

I am talking about the engine it's self. The long block is VERY stout!

Definitely not a stock or unmodified long block. There is no doubt that the head hardware had to be upgraded to keep the head from lifting with the amount of boost and nitrous he was running. The stock 6.0L heads would not hold up to that kind of pressure either since they were prone to crack at high hp. There is also no doubt that the cams also were also changed out for more power and air flow instead of the stock one which was designed for emissions.

I don't even think the short block was stock. Don't get me wrong, the stock connecting rods on the 6.0L were strong, but not 1,000 plus rwhp strong. Heck, I don't think any of the competitors have stock connecting rods besides the low end guys running sub 800 rwhp numbers. The only thing I would think is stock in his 6.0L short block was probably the block itself and the crank.

I watched a GM come off the line at Abbotsford BC Raceway broke front axle and it was ugly! Truck wobbled and looked like it was going to hit the barrier.

Probably why only one GM in the competition. Weak link for sure, even seen a couple along the freeway with tire pointing to the side giving them a Marty Feldman look.

Is there a ban on " smoking coal" that happens in diesel drag racing?

Rolling coal.......

And, no, there isn't.

I have noticed that the diesels pump out some black smoke under acceleration

You do need to beef up the tie rods if launching in 4X4, if not set up right you will start the front wheels hopping and if you don't let off you will tear stuff up. A go Pro works well for seeing what the truck is doing.

Enough to put on the smack down. :W

Like all heavily bombed trucks the heads have to be fastened on better than the factory does, or they launch towards NK like missiles! The 6.0 has always been a capable engine, just getting to last was the issue.

Too bad none would last even a short trip to the grocery store. Longevity and power don't mix well.

Many of the previous years contestants returned year after year without touching the internals and were daily driven. These diesels can last a lot of miles at high power levels with proper tuning and supporting mods just as long as you don't tow with them at those higher power levels which a lot ignorant people did back in the day. Luckily, most modern tuners shift on the fly fuel mapping and you can go from tow to go with a flip of a switch.

I bet the new ones are not' daily drivers' in any area with emissions testing. None of them have any emission mandated controls.

Fun to watch but I have no desire to own one. My old 7.3 puts 350 to the rear wheels and 650 pounds feet of torque with OD locked out. Plenty enough for me. Gets 18 on the road too.

I'd never install an aftermarket tuner because advancing the injection point on any diesel stresses the internals way too much for reliability.

When you start fueling a Tier 4 compliant motor, all that soot has to be consumed by the SCR and the DPF and that shortens their life span as well.

Finally, at 68, I'm too old for that nonsense.

A Diesel and Powertrain stressed at that level would not last very long. Might as well have a BB/ Gas Funny Car as a daily driver. They are really only good for show..:R

No matter how many times you regurgitate that, it is still wrong! Many of the big power trucks ARE daily drivers! Heck, one Truck Trend project truck (1989 Dodge D250, Project Rust Bucket) put over 900HP down to the rollers, that with an untouched factory bottom end! I saw a 1000+HP Ram go over 1,000 miles towing a trailer...it had over 150K, and was a daily driver.
