With the announcement of DC 650 1500 street truck which features a 3.0l whipple supercharger. the question that comes into my mind is that if ram itself can make 650hp 600lbft tq. out of a hemi 5.7l reliably while still offering 3 year factory warranty. Maybe 5.7l engines are not that bad at handling boost. I know they have the best tuners/engineers who calculated everything precisely to make it work but even at least they have to be running 8-10 psi of boost to make that kind of power. While everywhere i read online and it says hemis cant handle more than 6-7 psi reliably. Also dc 650 probably just have upgraded injectors and a blower kit. I dont think so that they changed anything internally. Speaking on the powertrain which also means that the transmission (zf8hp75) is also very much caple of handling that power and torque reliably. More than 553lbft torque that is advertised as safe range by zf. What are your thoughts?

factory supercharger for 5.7L?

i know ram/direct connection released their supercharged street truck not too long ago. any idea when the blower kit will become available for regular trucks?? would be interested if it comes out with warranty instead of going third party with no warranty

The 5.7 can handle boost far better than the 6.4. I have local friends who have done junkyard 5.7 Hemi swap into classic Mooars that they run at the drag strip . Low 6 sec 1/8 mile times. Using single turbo. Not sure exact boost levels but it's well over 10 psi. Claims 700+ wheel horsepower on E85. These are stock bottom end blocks. Not even a cam upgrade.

The also may have changes a few internal parts to accommodate the power upgrade

that's just the bumper to bumper warranty, i'm pretty sure the powertrain warranty is still 10 years 100k miles...

There is no info about it yet. Im just assuming. Hopefully when DC comes out with a kit there will be more clarification

The trucks are already at dealers and on the roads

I wouldn't be so sure. (I am happy to be proven wrong though if someone provides it in writing.)

For example, Ford's supercharger kits for the 5.0 Coyote come with a 3 year/36k mile warranty, but they have a bunch of footnotes:
- Only good from in-service date of the vehicle, not the supercharger install. So if you have a two year old truck and throw the Ford supercharger kit on it, its only got a one year warranty on the kit, technically.
- The drivetrain warranty does not work for anything touched by the supercharger after that.

Of course, a good dealership can help slide some of that through the warranty process regardless of whats on paper, but long story short, don't expect the regular warranties to necessarily apply unless you get it in writing.

i'm sure one could reach out to direct connection and get a solid answer about their warranty lol
 
Parts added after you purchase a car/truck do not change the factory warranty, doesn't matter if its from the manufacturer or not.

According to an article from Hot Rod Network “Every rig comes with a three-year/36,000-mile warranty on proprietary Direct Connection parts, plus Ram’s standard 10-year/100,000-mile powertrain coverage.”
 
New member RWL11 recently purchased one. Might respond to one of his posts with any questions.

I ordered a DC 650 in Molten Red back in October, 2025. Got tired of waiting, so I started looking around. First, I wanted to see the Molten Red in person. I found a dealer that had stock trucks in both Hydro Blue and Molten Red parked next to each other. On a cloudy day the Red looked good, but so did the Blue. I went back on a sunny day, and found the Red unimpressive to me, and the Blue just popped! Yes, I have 2 B5 Blue Scat Packs, so I may partial to the Blue spectrum. I traded in my Charger Scat Pack, and now I gotta decide if I'm going to keep the Challenger now. After she hits 1500...

I found a dealership that had some for sale and they posted the original window sticker for the truck. It shows a 5–year or 60,000–mile Powertrain Limited Warranty although multiple articles I have read state that it comes with the 10-year/100,000-mi warranty.

Actually they can. Boltnon an aftermarket supercharger to your motor and see if they will warranty anything on the drivetrain.

I think all the window stickers show 5yrl60k mile. The 10/100 is kind of a like a dealer add on option you have to make sure gets put in the paperwork when you are making the deal.
