The long rumored 6.2L Supercharged Hemi, nicknamed "HellCat" will debut in the Summer of 2014 for the 2015MY. It will be based on the 6.1 Hemi - with a possible Aluminum Block - and displacing approximately 375 CID (6.2L). Horsepower output will be around 600 HP plus/minus with cylinder head technology developed for/and used on the current 392 Hemi due to its excellent flow numbers will be applied.
Boost (psi) to deliver the approximate 600 HP - plus/minus - stock would be in the 9 to 15 psi range to deliver the horsepower/torque numbers. Currently Chevy/Cadilliac uses 9psi to develop 580 HP in their 6.2L SC V8s and the Ford 5.8 SC V8 uses 15 psi to deliver 662 HP in their 2013-14 GT500. Expect 9 or 10 psi for stock boost giving the aftermarket plenty of room to mod up to 15 psi. A modded "HellCat" should out-horsepower the 5.8 SC GT500 due to the fact that you cannot change both pulleys - like on the 5.4 (2007-12) models. Even Shelby SuperSnakes (2013MY) with the Stage 1 setup (5.8) doesn't touch the Ford factory setup. The entire SC is replaced to deliver 850 HP (Stage 2).
Internals will be highly upgraded, as well as the remainder of the drivetrain to handle the horsepower/torque requirements. Direct Injection and other measures will be applied to deliver MPG, with possible Rear End Gear Ratios being lowered as well for 6speed cars from 3.92 to 3.64 range.
For transmissions - a 6speed Manual and either a 5 or 8 speed (still possible) for automatic cars. Nothing yet is totally confirmed on the remainder of the drivetrain upgrade. However, look for the SRT 6.2 SC "HellCat" package to be in the same ballpark as the ZL1 and GT500.

Additional Info ....
The Hellcat SC 6.2 Hemi Package will include Beefier Rear tire/wheel package ... 20x10.5-inch w/205 or 305 wide rubber depending on the Anti-Spin diff Final Drive Ratio. The tires will be similar to the GT500 with Goodyear F1 Ultra Supercar G2 compound and tread pattern. The package will also include the 2012MY intro 2- and 3-mode Suspension, plus 2013MY Launch Control
There should be approximately a 150 lb. weight reduction on a SRT with the new "LA" floorpan (6speed Manual/8speed Auto) and Aluminum Maserati/Alfa fashioned sportier suspension replacing the Mercedes suspension.
Also, a new Steering Column which means a NEW Styled Steering Wheel.
