I'm a little suspicious of the 100lb weight loss claim. That's because the stock iron block is already a pretty light piece.

I also am questioning the part about it being a 7000RPM enginne. We've all read plenty on why the Hellcat uses a 6.2L engine instead of the 6.4L....so going even bigger seems counter to that line of thought. Especially when they're using a 4" stroke.

FCA stopped making the BGE block earlier this year and there was rumors that it might be discontinued (like the hellcat short and long blocks), but FCA is currently making the BGE block.

???

Bull,

Earlier this year, BGE block was back ordered, none were available any where, (now ask me how I know). Apparently FCA makes them in batches. As soon as they became available I ordered one. The concern was that is might be discontinued, just like the hellcat short block. I have learned that their are no guarantees the parts will continue to be available. Another example is the Demon blower. It can no longer be purchased, the part number for the blower disappeared.

From this MT article....

"Second fun fact: While the Hellephant engine inhales through the Hellcat's 92mm throttle body, its blower is designed to work with a 105mm throttle body if—just spit-balling here—one were looking to make more than 1,000 hp running on racing fuel."



As to the block weight...

"Another important differentiator for this engine is that it utilizes an aluminum block that weighs 100 pounds less than the iron blocks on the less hellish/demonic engines. The block, which is also used in Mopar Dodge Challenger Drag Pak race vehicles, bears no relation to the former 6.1-liter Mopar performance aluminum block. The SRT team spent a year engineering this one, employing lots of webbing and gusseting on the sides and in the valley of the block to control torsional vibration. The heads are essentially shared with the Demon and the camshaft employs variable valve timing but features higher lift to support the greater airflow involved in generating 1,000-plus hp. All of the internals are forged to withstand the cylinder pressures at play here and to enable the engine to rev to 7,000 rpm. These forged internals are also likely to be offered separately."

I'd hate to have to replace the 2.7 with a 3.0....

Unless of course you're trying to keep everything "Factory original"...

Thanks for the information the older mopar performance block referenced above is the aluminum block I was told to stay away from.

Wish this was just plug and play... and 100 pounds is a 100 pounds.

The hellephant should drop right into a hellcat or demon and just need tuning with the factory ecu.

In theory anyway.

Actually, I was wondering this myself and unfortunately I missed those must reads!

Can anyone help a brother out?

Fan Bloody Tastic. Awesome.

 

[toplescuda]

So it’s 1000hp on 93 and come with a unlocked pcm Soo what’s she gonna make on some q16 or e85 ??

No clue as to truth. But someone on Facebook said I at 6200. On race gas. It made 1081 hp

The 6.2L H/C uses the iron truck block from the Ram 2500's 392 motor, then reduces bore to reduce cylinder stresses IIRC. A short read comparing the 392 Apache to the H/C to the Demon engines can be found here.

As I recall the Hellcat had a special block that had the water jackets extended lower. The goal was to keep the water jacket within the swept area of the piston. All three had the same bore diameter but the 6.2's had a shorter stroke which lowers piston speed and increased the rod ratio which is desirable in this application. Another side benefit of the short stroke was increased main/rod journal overlap which increases crank strength. All these features are beneficial in a high horsepower application. Now to get to 426 cubes the stroke has to be lengthened so the crank for this Hellephant must be about the closest thing you can get to Billet Steel... to hold up to 1000HP/950TQ. Man it's just cool to be a Mopar Guy these days!

No love for M6....

Only a 10 Speed Manual with Titanium Gears will be offered

Interesting fact about the Demon blower.
Wonder if the Redeye was a 1 year only car and and the 3.0L will be the supercharger of choice moving forward.

 

[Muscle Car]

Bugatti has a 1500hp that is legal for sale in the US. And a 1000hp Veyron before that. I think its possible for Dodge to get a 1000hp engine through

Who knows, it might not be possible today for Dodge to make a California legal supercharged 426 CI engine with a 3.0L supercharger on top.

One contributing factor the Bugatti vehicles are legal is because of a specific reason. Bugatti uses four turbo chargers as its power adder (not a supercharger). A supercharger doesn’t have a waste gate, which means that smog will emit from a supercharger. Turbochargers on the other hand have smog altering equipment to lower the carbon emission of discharges.

I think you may have some wrong information on the turbo waste gates. All the waste does is open or close to regulate boost pressure . It's basically an exhaust bypass. All the exhaust still goes out the exhaust system. It does not alter the emissions what so ever.
