Rumor is that GS Motorsports will be announcing the availability of a functional supercharger for the 300C/MagnumRT this week using the Paxton Supercharger kit.

Here is a link to their site - this is not the purported announcement: http://www.gsmotorsports.com/hemi/supercharger.html

Strike the "rumor" comment. GS Motorsports just confirmed via E-mail that the announcment is coming out this week.

So start compiling your ECU questions folks . . . .

That's good news. Someone has apparently been able to modify the ECU.

With that kind of money ($4300) isent it better to spend a few more bucks and get an SRT-8??

And the folks at GS Motorsports confirmed that they indeed have cracked the ECU.

With the SRT-8 you:
Keep the warranty
Higher Resale Value
Upgraded rims and tires
Upgraded brakes
Upgraded handling
Respect



A supercharged 300c would be:
A few Thousand cheaper then the SRT.
Be much faster then a stock SRT-8.
Head snapping torque
Insanely Fast
Void the warranty
Would not brake or handle as well

Should run 0-60 in under 4.5 seconds no problem.

Since I already have a AWD 300c that would be my route.


It would be harder to supercharge the SRT as it already has a 10.3:1 compression ratio. The SRT gets it's peak power around the 300c's Redline and it has only marginally more torque. A Supercharged inter-cooled 300c would have ungodly torque even at low RPM's. The AWD would make the fastest setup with street tires.

I had a Turbocharged intercooled AWD GMC Typhoon that was running 21psi of boost. That truck did 0-60 in 4 seconds flat.

My initial question is; wouldn't the compression ratio need to be reduced to add a supercharger? I think that the hemi's rate of 9.6 may too high to supercharge, without problems of longevity.

And what about our trans problems???

What trans problems are you talking about?

Would depend upon where the waste-gate is set. But, 57.....I believe you have tripped upon that one item that will eventually make you pay for your abusive ways. Yes, it'll work....but only for a while.

Not something for the shallow of pocket, to be sure.

[goddardzilla]

design limit exceeded?

And what about our trans problems???

Thips
Do you mean the design limit of the trans @428 ftlbs torque? The shorter life caused by the extra torque and not having the same "shift kit" and shift software that the SRT8 has?

so any confirmations that this supercharger will fit in a 300c or a magnum, any restrictions with the AWD, and has any one contacted them yet.

 

[Model 57]

Checkout the website listed in the 1st post or 2, according to the site, it will fit the 300C and the Magnum.

 

[300CAWD]

I would seriously be interested in this. I am gonna go ahead buy it as soon as it hits the market. Any One knows what the labour cost(please no suggestion on DIY FOR ME) on this install. I am very auto challenged and lets just keep it that way.

Any restrictions on the AWD or MDS.

What exactly is supercharger, I know one of the jaguar xj models comes with a factory supercharger, Do i need to spend a grand on getting the borla exhausts and about 200 for the intake.

Warranty?
Should i cancel my 100K Mile warranty?
What specific components in the car will i loose the warranty on?

I just ordered my custom license plate after seeing this thread. "NO SRT8"

I just wanted to add my thoughts on supercharging.

I supercharged my S2000 (11.0 to 1 compression ratio) approximately 4 years ago and have had no problems. I have increased the hp and torque by approximately 50% over stock. Note that I am not drag racing the car on a regular basis at all. Just auto-crossing and having some acceleration fun on the roadways. The reason I choose to supercharge the car as opposed to turbo it is that with the supercharger the boost builds gradually (especially for a centrifugul type of blower) - minimal boost at lower rpms. Thus minimal harm to the engine unless you live in the high rpm range all of the time. If I were to turbo the S2k as some others have, I would lower the engines compression to say 9.0 to 1 and add a lot of boost and reinforce the diff (500+hp and 2,800 lb would be fun).

One of the disadvantages (at least for me) with a supercharger is the almost whistle like sound due to this mod.

Installation Cost - For my S2k it was $600 including dyno but most performance shops wanted $700 to $750.

I know a guy that does the supercharger installations for our Marauders in the Detroit area but he only does Fords (Alternative Performance). Maybe you may want to call Livernois Performance here in the area. They do a lot of different performance cars. For our Marauders the installation is about $1800. This includes the test and tuning. Good luck.

.........i think that i have just regained consciousness after the whole 21 psi on a typhoon remark. i am glad to see that there is finally a supercharger available for the hemi. with that, you can ensure yourself that there would be nothing comparible in its price range and class that could touch it. i havent checked the website out, but what are the specs? is it a centrifical/intercooled setup?

 

[bigslim]

I see that it is not a "Roots" type blower. This means that the torque band will be at the higher end. With a car this heavy you will probaly need to change the rearend to taller gears and get a torque converter to be real effective. If this is the case you could be spending more than what is the initial investment. Roots type superchargers give you more lower end torque which is better and more usable in a heavy car. Centrifical blowers need help getting heavy cars out of the hole. This is why the rearend change and torque converters. I hope you guys have good luck with the results.
