Read this today on some hemi engine forum; have no idea if it will come to be:

An “Apache 392” has reportedly been under development, a supercharged version pushing out over 600 hp. Rumor has it going into the Challenger and Grand Cherokee. Allpar member “autojunkie” wrote:

I can say that the 392 supercharging is a done deal. It was spotted on some Chrysler engineering documentation and slated for 2014. It specifically mentioned the Grand Cherokee for production intent.
I've seen many engineering documents that had projects that were eventually cancelled. The document detailing the supercharged 392 did point to production-intent, but it does not mean that it couldn't fizzle off the plan still.

Could spell bad news for the ZL-1 Camaros, but why wait so damned long? The Challenger will have been axed by then.

Yes, had heard a while back that this might be in the works. Either that, or a Aluminium 426. The goal is about 625 H.P. Hope Dodge can make one or the other happen before 2014. Keep it around 55K, and thay will sell all they can make. I will be first in line!

wow.... i hope this is true. id hate to trade my car in but this could do it for me...

better start saving now

The Challenger is not going to get the axe in 2014. Dodge is not going to supercharge the 392. IMO, they will bring back the 426 Hemi in MY2014 - exactly 5 years after they showed off a crate version - that is how long it took for the 392 to make it into production. This has been discussed on allpar.com and they would agree that a 426 makes more sense than a supercharged 392. 426 is the magic bullet for Mopar guys, not a supercharged 392. Although, a supercharged 392 would be badass, it's just not going to happen. The 426 is coming guys, count on it. Just before the 2016 MPG/Emission hike.

I wouldn't be so sure. It costs in the 100s of $millions to validate a new engine for street use. The 392 is already validated--supercharging it would not cost nearly as much as validating the 426. Swapping in forged internals and adding an S/C would be a much lower-cost way to really up the ante IMO--and I see no reason why an S/C 392 could not produce in the 600+HP range.

While bringing back the 426 based on the new aluminum crate, similar to what they did w/the 392 is feasible and would inspire a lot of nostalgia-based purchases, it may be too cost prohibitive to do so.

Interestingly enough, they have already performed durability testing on the aluminum crate 426 w/a turbo setup. Wouldn't that be something--a factory turbo aluminum 426... now we're talking 650-700HP... That'd be higher output than the NA 512 V10 in the drag pak. One can always dream.

I 'd like to see a supercharged 426. Popular Hot Rodding drag tested the 426 1320 Drag Pak, in warm weather, and got a best time of 12.5 [email protected] 114 mph.

I found this interesting posts on chargerforums and allpar:

"The 8 speed being delayed was a failure, not a strategic decision.

Chrysler wanted it for the 2011 launch of the 300 but they had problems with getting it to work and ZF couldn't get it done it time (BMW. Mercedes, etc. were bigger customers and ZF couldn't spare the resources to make it happen).

The original plan for the progression of the performance engines had the 392 being released in 2011 and the 426 coming out in 2015. That died with the bankrupcy. The 392 doesn't have any room for performance increases, they had to de-tune it to get the engine longevity (which makes after-market performance mods dicey). The 426 engine is dead (don't mistake the crate motors for ever making it into production vehicles). The engine reportedly cannot pass durability testing at 525 horsepower, due to piston skirt issues when tested near overheat conditions. (Durability testing reportedly requires 200,000 miles MTBF and extensive testing under extreme conditions).

Fiat has no interest in V8 engines. They want V6 turbos for HP.

Watch closely over the next 5 years, you are watching the death of the Chrysler performance American muscle car. After this, it will become Euro-ricer territory. The last of the V8 muscle will exist in trucks and SUVs for a little while longer than that, and then even they will be gone."

.".. to supercharger a Hemi correctly, you really should swap out the pistons for some with a little more meat between the rings. I personally cannot see Chrysler producing a production supercharged 392 car direct from the factory because it would require different engine internals to meet and exceed all the OEM specifications. Mopar Performance is a whole different animal. If it happens (and I seriously doubt it) it will be a performance kit from Mopar Performance with the typical 12 month/12,000 mile warranty."

Well, they still have the V10--and while they're already going to produce it, and already put it first in a concept and now in the drag pak thus the engineering work is done--if they simply validated it for street safety they could sell an even higher-end Challenger SRT10. Price it around $55-65k--between the SRT8 and Viper. Conversely, they could put the V10 in the 300 and then be able to compete w/the CTS-V.

I certainly agree with you that a supercharged 392 would cost considerably less than an all new engine. It would also take less time. I just do not think they are going to do that. Have they ever supercharged anything in the past? I just have a strong feeling we are going to see a 426 hemi. It will take the same route as the 392 - crate form, then darg race form, and finally street form. Either way, I think we are going to see a higher performance Challenger in the next few years.

No, they have not supercharged anything, but they have done turbos, and are in fact planning to turbo the Pentastar.

Factory Turbo or S/C, I'd take either one.

Would people be happy with a twin screw supercharged 392?
