The Ultimate V6 Performance Thread

Samoan Tsunami - Sway Bar Reference
After seeing a lot of threads started on V6 performance, I’ve decided to make a comprehensive resource going over all the known performance upgrades. I’ll try to go into a little bit of detail about the parts and where to find them. They will be arranged in tiers regarding performance, assuming that the stock engine dyno’s around 175 RWHP. Because I don’t like to make up imaginary numbers, every horsepower number depicted in this thread will have an acceptable error of ±100 RWHP. This section will be based mainly on the 3.5l V6.
Tier 1: 175-190 RWHP and Ft/Lbs Torque
Cold Air Intake:
It’s been noted that Intakes are generally all the same and that the performance gains will be about the same as well. Some of the higher end models will come with a compartment that seals the intake from the rest of the engine which does a moderate job of keeping the heat from the engine bay out.
Examples:
AEM Brute Force
AFE Stage 2
Big Bully Intake
K&N Aircharger
Mopar Performance 3.5l Intake
LMI Fender Mounted True CAI
Electronic Tuner:
After looking into Jet chips and Superchips, It seems that the Predator is the only one that is vehicle specific to the Charger.
Examples:
Diablosport Predator
Exhaust:
The majority of gains are through the use of catback exhausts, therefore full exhaust kits will be the only ones covered here. Many owners have swapped their V6 exhaust for a stock R/T exhaust. This is generally the cheapest route to go exhaust-wise. The SRT8 Exhaust does not generate enough backpressure and, as a result, is not the best exhaust performance-wise.
Examples:
RT Exhaust
Daytona R/T Exhaust
Borla Catback (single and dual)
Dynomax (single and dual
Magnaflow Catback (single and dual)
Gibson single rear catback exhaust (single)
Pypes StreetPro, RacePro, Violator catback exhausts
Zoomers (single and dual)
Also, Do not forget the Proper Fluids
Examples:
QuantumBlue Custom Blended Lubricants and ACES IV Fuel catalyst from BND Automotive.
Tier 2: 190-250 RWHP and Ft/Lbs Torque
Ported Throttle Body:
The next step to help the vehicle breath after the Intake. With the right tools it’s possible to port your own. Just follow this link - http://www.chargerforums.com/forums/showthread.php?t=100772
Examples:
Modern Muscle 71mm CNC ported throttle body. (SpeedLogix)
Aecarbon Ported Throttle Body
Ported Lower Intake Manifold:
The third step to help the vehicle breath. Replaces the stock manifold.
Examples:
Aecarbon 3.5l Ported Intake manifold
Jet Hot Coated Valve Covers:
Reduces surface temperature of valve covers and plenum temperature.
Examples:
Aecarbon 3.5l Jet Hot Coated Valve Covers
Exhaust Headers
Helps free up the exhaust system
Examples:
Stainless works Long tube headers
JBA Shorty Headers
OBX Shorty Headers
Camshafts:
Currently only produced by Inertia Motorsports
Examples:

Version 1.1
Version 1.2
Cylinder Heads:

The Ultimate 2.7 V6 Performance Thread - Written by Biged83
The parts will be arranged in tiers regarding performance, assuming that the stock engine dyno’s around 135 RWHP. Because I don’t like to make up imaginary numbers, every horsepower number depicted in this thread will have an acceptable error of ±100 RWHP. This section will be based mainly on the 2.7L V6.
Tier 1: 135-145 RWHP and Ft/Lbs Torque
Cold Air Intake :
It’s been noted that Intakes are generally all the same and that the performance gains will be about the same as well. Some of the higher end models will come with a compartment that seals the intake from the rest of the engine which does a moderate job of keeping the heat from the engine bay out.
Examples:
LMI Carbon Fiber Intake
K&N Intake

Royal Purple Oil
Tier 2: 145-180 RWHP and Ft/Lbs Torque
Ported Throttle Body:

Torque Converter:
To my knowledge there is only one produced by Intertia Motorsports and it is only for the 5 speed NAG1 Transmission.
Examples:
Inertia Motorsports 3.5l EDGE High Stall Torque Converter
NAG1 5 speed Flex Plate
This flex plate is lighter and stronger than stock, allowing the engine to rev faster.
Examples:
SpeedLogix Flex Plate
Limited Slip Differential Upgrade:
It is possible to upgrade from the stock differential to any HEMI LSD kit on a NAG1 5 Speed car. This will also require swapping hubs and axles.
The link below documents a successful swap to a Challenger LSD.

Rear Gear Swaps:
Currently, this is only an option with the NAG1 5 Speed transmissions and HEMI differential Swap
The Available Ratios are:
3.07
3.23
3.28
3.33
3.55
3.64
3.73
3.90
4.10
I've been told it's possible to change the 4 speed rear gear between the 3.06 in the 3.5l and the 3.73 in the 2.7l without putting the car into limp mode. To my knowledge this is the only gear change possible on the 4-speed at this time.
