2006 Charger Forged Internals

[Lanmon28]

Okay, first of all...let me start by saying that I'm kind of new here. I've pretty much been a mustang man most of my life but I am anxiously awaiting the arrival (for sale, I mean) the new Dodge Charger SRT8. This is an awesome looking machine and even for a 4 door I love it...allowing husbands (maybe even wives in some cases) to have a sports car and still drive the family to Wallywold (I believe that was supposed to be in FL?)

Anyway, on to my cofusion (you knew it was coming, right?) This new Charger is rated at 425 horses and 420 pounds of torque. That's some pretty good power. Right up there with the new Shelby. Now, I know this is SUPPOSED to be kind of a family car but to give a car 425 horses means you are kind of competing with the big boys of muscle and rightfully so...it IS A Charger, after all. But, I digress...and onto my real beef. Maybe this is just because I'm used to mustangs and the abundance that they are and the room for mods but...I would NEVER put that kind of power (the 425 horses...and neither would Ford considering even the lower horsepower Cobras had them) in a car and NOT put forged internals. I mean...I know it DOES have the forged crank but why not the pistons, rods, etc? Why go through all the trouble to make your crank hold up to supercharging or larger power but yet not make the REST of the engine capable? Granted forged pistons and rods would have jacked the price up another couple of thousand but the guys at Dodge HAD to know that those of us who would be interested to BUY this sporty new Charger would want to BEEF it up to hang with Cobras and stuff (and there again I haven't forgotten that it's a family car, technically but it's a CHARGER!!!). This concerns me. I mean...with a simple bolt on of a supercharger and fuel system upgrade, this thing would have been able to probably leave the Cobra in the dust and still get to Wallyworld before they start the renovations and we have to go postal as Chevy Chase felt compelled to do. I'm mainly concerned about this because it actually COULD be the deciding factor on whether or not I end up with one of these. Although I love the hemi engines and the Charger itself, I am greatly disappointed that my hands will be pretty much tied and I'll have to settle for what the car has. I know I could probably do SMALL upgrades to exhaust and maybe the headers to this MASSIVE 6.1 (same liters as the new Z06 corvette, I might add) but for the displacement this car has, it's VERY disappointing to be limited in this way. Can someone help convice me to get one anyway?

This will convince you.....

GS motorsports supercharger producing 500 Rearwheel HP and 507 Rearwheel Torque................ :rockon:

How do you like that?

Here are the changes from the 5.7 to the 6.1

The basic, deep-skirted engine block structure was redesigned with reinforced bulkheads to handle higher loads.
To get more air in and out of the cylinders, SRT engineers bored out the diameter of each cylinder by approximately 3.5 millimeters in order to increase the total displacement from 5.7 liters to 6.1 liters. Cylinders are honed with torque plates to ensure a truer bore, to reduce friction and increase power.
Oil squirters, aimed at the underside of each piston, are added to aid piston cooling for engine durability. A special oil pump pressure relief valve is added to accommodate the squirter oil flow.
The oil pan and windage tray are modified to manage oil return to the pan sump at high engine speeds and improve power.
Larger-diameter, flat-top pistons with high-load capability are specified to handle the SRT 6.1-liter HEMI’s compression ratio, which was increased to 10.3:1 from 9.6:1. Connecting rods are redesigned and make use of higher-strength powder metal material. New floating piston pins are introduced to handle higher loads.
The SRT 6.1-liter HEMI’s crankshaft is forged from micro-alloy steel and rotates in tri-metal main bearings for high-load capability. The crankshaft damper is retuned for higher engine speeds.
The SRT 6.1-liter HEMI features cylinder head ports designed with larger cross-sectional area. This allows 11 percent higher flow in the intake ports, and 13 percent higher flow in the exhaust ports.
A billet steel, high-strength camshaft features more overlap and lift for better performance.
Intake valves feature hollow stems and 2 mm larger heads compared to the 5.7L engine, allowing more air flow. The hollow exhaust valve stems are filled with sodium to dissipate heat efficiently. Premium valve springs with external dampers enhance the SRT 6.1-liter HEMI’s valvetrain and enable higher engine speed operation to 6,400 rpm. The valvetrain system enhancements allow the peak output engine speed to increase to 6,000 rpm from 5,000 rpm — a 20 percent increase.
Engine breathing is improved with specially designed intake and exhaust manifolds.
The cast aluminum intake manifold is designed with shorter, larger-diameter and tapered runners for high-speed tuning. Internal runners are core-dipped to smooth the runner finish and improve air flow.
Fuel injector flow capacity is also increased by 14 percent over the 5.7-liter engine. Electronic throttle control is shared with the 5.7-liter HEMI, but breathes through a revised high-flow air cleaner box outfitted with a tuned resonator delivering a deep performance sound character (and good for an extra eight horsepower).
Exhaust headers on the SRT 6.1-liter HEMI are individual tubes encased in a stainless steel shell. Exhaust runners allow increased gas flow while maintaining fast catalyst light-off, while adding 12 horsepower over the 5.7-liter engine’s cast manifolds.
To control the combustion process, SRT engineers fine-tuned the engine management system using dual knock sensors with premium fuel.

Wow, some impressive stuff there. You can tell that I'm new to the Charger forum, huh? I've read MOST of these on other sites but from everything I've read (mind you a LOT is from forums on the 5.7 hemi) says that current superchargers are cutting the life down serverely on the engines and causing them to fail. And this was from a lot of the actual speed shops that were putting these superchargers on them and dynoing them. Again, this could be older stuff I'm reading on the forums and it may be a whole new ballgame with the 6.1 Hemi in the Charger SRT8. I did read that about the oil squirters that help to cool down the pistons but I wasn't sure how efficient that would be up agaist a supercharger. So, this RAM truck is not having any problems with the addition of the supercharger? What are they using to allow for upgraded fuel consumtion fdue to adding the supercharger? Is it stock fuel pumps? (You can tell I'll probably be upgrading the minute I get the car...who needs a warranty, right?). LOL

those numbers are from a magnum srt-8 go to the gsmotorsports website for more info

Lanmon28, there is Hemi 5.7 in a RAM 1500 that is currenlty running NOS and was running 12.7's in the 1/4. He hammered on this truck for two years running as fast as 13.4's all motor without any failures. He has sense traded it for a 1500 Daytona. There are others on stock internal running in the 12's also.

I feel like this is a testament to what the 5.7 and 6.1 Hemi motors can take. If he can do this for two years in a cast internal 5.7 Hemi, then one should not worry to much about what the 6.1L can take.

The user name is Hemi777. Just do a google search on the user name to get videos and details.

I wouldn't worry about it all that much. The Ford V8s seem to be weak engines. A 3.8L V6 Mustang can run 10s on the stock bottom end.

Well, thanks for the info guys. I have to say since I'm just becomming a Charger fan I don't know much so I'm not at liberty to debate any of this. I guess I've only read the articles about the superchargers and what people say the problems they're causing 5.7's. What I do know is that I get a little nervous because my current Mustang GT had stock internals once...and I put a vortech on it and had it tuned...it was probably pushing between 350 and 370 RWHP with the exhaust mods and headers and blew up on me at around 5000 RPMS in 3rd gear. So I finally got it built with the forged internals and now I'm pushing about 505 RWHP...but the thought of running a car with a supercharger that's already running 425 flywheel (around 375 RWHP I would speculate) and getting 500 out of it is just a bit scary...but, who knows how reliable this oil lubrication system is? I WAS told by a guy at the Dodge place just today that he has a friend who sent his Charger RT to CA to some place (he wasn't sure of the name of it) who had forged internals put in the car, suspension upgraded and a supercharger put on it and it's running around 525 RWHP. Anyone know of such a place because if it exists, it might be worth looking into. :)

if its in california its GSmotorsports.

the superchager is made by paxton

I am wondering if anyone has any advice for upgrading my 2006 Dodge Daytona Charger. I have added K&N Air, Magnaflo Exhaust, and Mopar Headers. I have contacted GS Motorsports about Supercharging my Hemi. They have a NOVI 1200 6lb boost or NOVI 1500 with 8-10lb. I am wondering if anybody has any experiece with the stock Hemi abilities to handle the Supercharger without doing alot of internal forging and upgrades. I race occassionaly 1/4 mile only at Friday Night Racing. I am simply looking for more horse power without doing damage to the engine or reducing the life of the engine. I have heard rumors that putting a supercharger on will cut engine life in half. I am pretty new to all this stuff so if anyone has supercharged their stock Hemi I would appreciate any advice. Thanks. Roger
