Whipple Supercharger for 6.4

I have a 2024 2500 gasser and I'm pretty settled on a Whipple supercharger whenever they offer it. Anybody heard any news or expected release?

I considered Procharger first but they're meant more for top end power. I'm not racing, I just want more low/midrange.

Adding a Borla cat-back today. I'll do Kooks headers/cats once they're available and my stock manifold cracks.

Going to sound great, would love to hear it once you have headers on it!

Will do!

As is, with just the Borla it's still very tame. You can barely hear it in the cab. So tame in fact, my fiancé said it needs to be louder. F'yah, I can make that happen. LOL

Please post a video of the Borla.
 
Interested in hearing more about the blower endeavor. I don’t think too many have ventured that way in the HD platform.

I just received a response from Whipple and currently they do not have plans to offer a kit for this platform. But that doesn't mean it won't be offered in the future.

I need to look into this further, but I think they sell the base unit that you can build a custom system from. The biggest problem to solve is a connection between the throttle body and the supercharger. This is usually a cast aluminum elbow that connects the supercharger to the throttle body. A custom piece would involve a generic aluminum elbow welded to custom flanges. After that it's similar enough to all the other gen 3 Hemi 6.4L platforms that you could use most of the same components (injectors, tune, etc...).

In that line of thought, I wonder if I could buy a kit for a Charger SRT and just adapt it to our 6.4 with a custom elbow? Hmm...
 
Without researching it I am going to assume the 2500 6.4 versus a charger 6.4 has completely different heads. You would have to design and make your own custom lower intake manifold that bolts it from the heads to the supercharger. Within that lower intake manifold you would want to bolt on an intercooler of sorts and then mount a heat exchanger to the front of the truck. Oh and fab an intercooler coolant tank to mount somewhere. Then wire up and plumb a coolant pump for said tank to intercooler to heat exchanger and back.

I'm building a forged 6.4 right now for my Grand Cherokee SRT. I'll compare these heads to what I can see on the 2500. I suspect the intake mounting is the same and only the porting is different.

Here are some pictures of my ported SRT heads. Ports are enlarged of course but the chambers have been softened for forced induction as well (large bevel fore/aft of each chamber).

After looking at some examples I found online, it appears the primary mounting points are the same between the truck and SRT heads. There are some nuances, but I don't see any show stoppers yet. Worst case scenario I swap to fully built SRT heads. That wouldn't bother me.

One thing I didn't catch was the truck's EGR system. My SRT doesn't have that. I'd prefer to delete that anyway, so again, I don't view that as a show stopper either. I don't see the Whipple clearing it. Which is maybe why Whipple isn't working on a kit for the truck engine. Meh...

The 392 and 6.4 BGE intake ports layouts are identical. You can swap intakes between the two engines.

So, while Whipple does not make a "kit" for the 6.4 BGE, they do for the 392. You would have to do your own research in to tuning. There are tons of people out there with Whipple'd 6.4 BGE's. It's actually the preferred platform for boost.

BoostedMotorsports on YT is building a 427ci stroked and whipple'd 6.4 BGE to go in a Dakota. All forged internals though, which is something I would recommend.

Thanks for confirming that. I'll check out BoostedMotorsports.
 
The only engine with no interchangeable cylinder head ports is the Hellcats. 5.7 and 6.4s can be all swapped around. the issue you will have trying to adapt a 6.4 car is the intake is the wrong direction.

I think you would be better off trying to adapt a kit from a 5.7 ram 1500. That way the intake will be going right. 5.7 guys swap to the 6.4 Hemi truck intake all the time

This is what a Whipple for the 5.7 Ram looks like. I think most of your issues may come from the EGR system. But if you research the 5.7 to 6.4 Truck intake swap you may find a solution.

What about an intercooler system? Pump wiring, sensors knowing when to run the pump, etc.?

A lot of the plumbing and wiring will need to be custom. Fabrication is a given. And I'd suggest finding a good tuner that knows what they are doing before spending a dime on parts. Wide bands, tons of monitoring, a local dyno.

No one said it'll be easy, or cheap. Comes with the territory.

Agree, and I am really hoping he takes this project on because I have wanted to see someone do this since the 6.4 powerwagon has been out!
