Hellcrate

[ChargedNJ]

Hey fellas. Been a while since I've been around. i finished my patio project and I'm ready to get back into my 68. Of course the first thing I come across after doing some googling is the hellcrate....wow! I dis a search of the term in here expecting to see a bunch of discussion on it but no results! I'm shocked! Any thoughts? Is there a thread I missed???

It's an awesome engine,  but not many people have 20k laying around.  Also if you use that engine, you'll need to upgrade your transmission, rear axle, brakes, suspension and stiffen up the body.

Looks like any +500HP crate motor is north of $15K.  I guess the advantage here is that this is a modern motor tuned for everyday driving, fuel-efficient, etc.  Dumb question on my part.....what gives the older motors that classic sumble/rough idle that you dont hear in new ones?  Is it the carb?  exhaust?  combination of things?

The 6.4 Hemi (392) is sitting at 485HP, and under $10K.(granted you will need a $1700.00 Mopar ecu, throttle by wire kit to make it run, and then front drive alt/PS pump, and so on, and that ads up)
But the 6.4 is a very sweet engine, makes a ton of power, it is no hellcrate, but I dont think you can go wrong with a 6.4.(IMO)

To answer your question, about lope/ rumble sound of the older engines, a bunch of things come into play, but mostly the  camshaft design, duration and overlap.

It's meant to be the halo engine that very few can afford, and that hardly anyone really needs.  Much like the 2nd Gen Hemi and the Viper V10

I run in a Modern Hemi street series, I am the poor guy running a 2016 Charger R/T with the little 5.7, anyway, I have witnessed more then a few supercharger failures on Hellcats.
That being said, I have no idea what mods they have on their cars, and if they over reved the motor, or just the stress of racing has caused them to launch.
I think Dodge had a very common well know bearing issue within the supercharger, on first year cars, It may have been a recall.
I would hope this would be fixed and not something that would happen to a $20,000 crate engine.
The actual engine is built VERY WELL, and to handle a ton of abuse/use, it is a shame the superchargers not so much I guess.

As amazing as the Hellcrate is, I can only wonder what they will offer next, to top the hellcrate??
I am sure whatever it is, I will not be able to afford it. Out of the list of engines JB400 had stated, only the V10 is affordable by me, and only the truck version at that!!!!

I installed a 392 Hemi in my '70 Cuda at the end of 2017 and absolutely love it! Starts everytime, no issues and really quick off the line. It's not the torque monster like my 505 stroker, but its a whole lot of fun!

My '68 is going to get a stroked 5.7 3rd gen. Hemi with a 2.8L. Kenne Bell blower. Dependable and powerful.

That makes sense. I've talked myself out of it anyway over the last few days. Less about cost (because that kind of power will cost..crate or built up), but moreso because I want that choppy gallop rumble of old school muscle...it just won't be the same without it. Plus I want this to be an active hobby for me where I can get in there and tweak, learn, etc.

The other real motivation for me is to have this thing walk the walk. I'm too old to be street racing but I do want to make sure that I'm not going to get smoked by the average Honda Civic.

the hellcat is more efficient, probably more reliable, and (my turn to be Capt. Obvious) more powerful...but unless you need the 700hp for racing or something, it doesnt have the cool factor of say, a 426 Hemi that would be in the same ballpark money wise.

I don't need to be a world beater, but don't you want to be competitive? You've got this big, loud aggressive machine..don't you want to make sure it lives up to expectations a bit?

What does the flag represent, btw?

The blower failures on the Hellcat 6.2L was traced back to a bearing issue on the first run of superchargers...    They can be rebuilt / serviced but who wants to do that on a very expensive / new piece?    The later and current superchargers have had the bearings re-designed and have stood up to much more abuse.
