New 6.2L Supercharged Hemi

New 6.2L Supercharged Hemi - 06/19/12 03:03 PM

This engine is to debut as early as next year in special SRT8's.

I don't know how extreme they are going with it, but any speculation on power assuming the 6.4L crank and Apache heads with a smaller bore?

6.4L = 4.09 Bore X 3.72 Stroke (392)

6.2L = 4.03 Bore X 3.72 Stroke (380)

The GM LSA (ZR1 engine) dimensions are 4.06 X 3.62 and makes 580HP @ 9psi boost. The 5.8L in the GT500 makes 662 @ 15psi

Now if they could build a Cuda that weighed 3500lbs or less they would have something.

Bout time!
My 2010 SRT Challenger has had the Procharger on it for 8000 miles, ha ha ha

Now they need to put Rosie on a diet, there is a whole lot of her.

Hope they intercool it. They look good in the grill

they can build a car that weighs 3000lbs, has 700+ RWHP and sell it for under $10,000 and some of the guys on here would still find something about it to b!tch about....

Re: New 6.2L Supercharged Hemi - 06/20/12 12:18 AM

Its going to be a roots type blower on it apparently, like the ZL1 and GT500 have. Couple conflicting rumors, one says its definitely going to be a 'Cuda and one says Sergio Marchionne took a look at their Cuda concept and said no, just build a smaller / lighter Challenger instead.

So I guess we'll see.

Re: New 6.2L Supercharged Hemi - 06/20/12 02:33 PM





LA = Next generation Cuda / Challenger. The other L's are current Challenger, Charger and 300.

BT and DX = Ram.

Let's hope they design this block right. Thick bores to handle the boost.
Plus to help offset the cost of a small production run. Offer the same block to the general public for the same price as a bare 6.1.
You will sell a massive amount of blocks. Fiat r u listening?

Re: New 6.2L Supercharged Hemi - 11/17/12 04:21 PM

I think the only reason they're gonna build is for the Drag Pack cars to use against the COPO maros.
Posted By: MattW

Re: New 6.2L Supercharged Hemi - 11/17/12 04:36 PM

Your probably right but in the end I am only interested in the block for a resonable price.
My personal opinion is they drop the ball with the one off aluminum block. If they would of cast the 6.1 with thicker bores in the end they would of made more money with the bare blocks that people would of purchased.
A Production block that handles 1100 to 1200 of instant blower boost. For 1400 to 1800 dollars =
You have PRODUCTION heads that flow Very well. The only other missing piece is this block. This block is only required for the serious all out effort. I believe the 6.4 block is well suited for the average weekend warrior. But only time will tell on this. Matt

It'll probably end up there but thats not its main objective. As far as I know it's going to be in special SRT cars, I believe debuting in the new 2015 Challenger (or Cuda, whatever they end up calling it). I think someone said it'll be in the Jeep too in order to bury the Porsche Cayenne Turbo, BMW X5M, ML 63 AMG etc. (all 560+ HP twin turbo V8 SUVS that cost over $100K)

Scaling back is the LAST thing happening over there, they've invested something like 4.5 Billion in the state of Michigan alone since Fiat entered the picture in 2009. Wait until you see the Dart SRT4 - 350 HP + AWD. , among all the other crazy stuff coming out soon.

As long as the make enough power to make up for the weight, it will be impressive.

The LX's handle power better than they should. 4300 lbs and IRS don't seem to matter....

Nobody knows (that can talk about it), just that there will be a new car for 2015. This is Sergio Marchionne's (the Big CEO of Fiat, Chrysler, Maserati, Case and a dozen others) own Challenger, so I am confident they wont ruin it.



In an interview a few months ago he said "The Challenger needs to evolve"

-Doesnt sound like a Cuda to me

so true....

btw, I'm putting money on 6.4L bore destroked to 5.7/6.1 stroke (3.58", works out to 376CID or ~6.17L) and I wouldn't be shocked if it share the same block as the 6.4L

Who would have the production # s for all 6.4 produced?
If we could find this out maybe it would shed some light on the # of 6.2 that could be produced. Matt

6.4L was only in the Challenger for 2011, and 5265 were built. Obviously this year you have it in the Charger, 300 and Grand Cherokee as well but the Challenger is still the best seller of the group, with the Jeep a close second.

Thing is, the 6.2L isn't coming to replace the 6.4L, its to be a higher end model SRT8. Finding used 6.2's will be like finding hens teeth in the states and pretty much non existent in Canada.

All the more reason to come out with a good block for the racer enthusiast.

6.4L = 4.09 Bore X 3.72 Stroke (392)

6.2L = 4.03 Bore X 3.72 Stroke (380)

The GM LSA (ZR1 engine) dimensions are 4.06 X 3.62 and makes 580HP @ 9psi boost. The 5.8L in the GT500 makes 662 @ 15psi



The LS9 ZR1(Corvette) engine is 638 HP. The LSA ZL1(Camaro)engine is 580. Another version of the LSA as installed in the Cadillac CTS/V is 556 HP. The upside of a boosted engine is the simplicity of adding power. A simple pulley gear swap can pick up another 75 HP easily. Of course this voids the warranty.

The only advantage of this head is thicker decks for 30+psi of boost. The intake, exhaust and rockers are all the same.

A stock head can make just as much power, if not more.

There is alot of advantages to that head compared to the stock one


Here is that link

http://www.lxforums.com/board/f71/introd...er-head-310779/


This is a completely new casting made of A356 material. Thismaterial is approximately 2x the strength as an OE cylinder head.
All heads will bedrilled for both left and right exhaust bolt pattern and oil drain backs. Thisallows for heads to be interchangeable from side to side and also gives turbocars additional bolt holes for header flanges. One oil return will be pluggedusing a NPT plug to avoid leaks.
The deck thicknesshas been increased and additional features added for strengthening of thecylinder head deck.
Port wall thicknesshas been increased inside port and water jacket side, this allows for differentport shapes (smaller or larger) and adds strength to cylinder head.


All the turbo guys are going to love this head.

Granted 90% of the guys running genIII hemi's myself included the factory heads are more then enough

Re: New 6.2L Supercharged Hemi - 11/20/12 06:13 PM

Most hemi guys can't use 900rwhp effectively due to IRS and weight. Plus, the 8's are already being touched with factory castings. The LX's are going to run into a saftey roadblock really soon.

If a drag pack car is to use them, they wont need near the power and the axle/trans is already better. 640 flywheel is already deep 9's for a DP car. Being that they're class racers and not exhibition or "unlimited" class racers...no DP is likely to use them.

I don't think they're going to be the hit that everyone is expecting. If they changed the intake port enough to put a better than Drag pack intake on or had changed the valve angles, then I would be interested. Wicked things can already be done to the Eagle and that is the thinnest of all the Hemi Heads. The port can be drastically changed...to the point that it doesn't even resemble a factory port.

I'm not trying to be a cynic, but rather to give an informed opnion to give reason to a bit of the "Hype".
