The Transformation is in Process

[SRT-OSO]

Well, some of you guys may remember me as AudiOso and my 2005 Goodwood Green S4, my 2003 Brilliant White TT Coupe and my 2003 Atlas Grey A4 Avant. All three were sold earlier this year when I bought my 2008 Chrysler 300C SRT8 and my 2008 Caliber SRT4.

I did minor mods to the Caliber trying to keep it fairly stock since there were only 5056 of the SRT4's made. So far it has a CPE exhaust which is very nicely made and a Realtune ECU remap. The increase in power is quite stunning. The guys at Realtune dynoed this configuration at just shy of 350hp at the crank and 360 ft/lbs of torque.

The 300C SRT8 on the other hand has been a different story. I went all out on this car. I got the car really cheap because it has a carfax. When it was two months old it was hit and took a quarter panel on the passenger's side. Since the car effectively has no future collector's value I decided to build myself the first and probably only truly fast car I will ever own. I worked with Alex Jones at Arrington Engines and Bill Schurr at Paramount Transmissions to spec the following:

10:3 to 1 compression 426 stroker shortblock
CNC ported 6.1 liter heads
Arrington 607 grind billet camshaft
Billet main caps
Fully forged internals
Full Commetic gasket kit
ARP Head Studs
ATI 17% overdrive harmonic balancer
Diamond Racing push rods
Diamond Racing intake and exhaust valves
American Racing Headers 2.75" headers and resonated T-304 exhaust system

For the drivetrain I went with:

Paramount blueprinted and built NAG1 transmission (full AMG clutches and servos as well as valve body assembly)
Paramount lightweight high strength flex plate
Paramount 3400 RPM stall speed torque converter
Quaife helical cut gear driven differential
DSS 1000 hp axles and hubs

To finish things off I went with:

Arrington Magnuson 2.3 liter twin-screw supercharger kit
10 psi setup

Erik Storms who runs BFNY Performance in Plattsburgh, NY currently has the car, and it is in the process of being assembled. Here are some crappy pics of the build process:


























That's all I have for now. The car is supposed to be done on the weekend of the 15th. That's when myself and my buddy Erik Haun are going up with his 2006 300C. He's getting my old 6.1 liter mill dropped into his car. This will be a very interesting weekend. Erik Storms works very fast and carefully which is usually not how things happen. He said he can turn Erik's 300C around in two days, so we're going to hang out in Plattsburgh and nearby Vermont and take in the fall color with my newly invigorated SRT8. It'll be interesting to get this thing on the dyno in the spring.

Erik and Alex are confident that I'll be making in the neighborhood of 675 or so hp and 680 ft/lbs of torque at the rear wheels with this car running 10 psi of boost on pump gas. If I want more I can go with a stand alone pulley system and take it up to 12 psi which is the high end of what the blower can put out without overdriving it and running it too hot. Needless to say, I'm going to crap my pants the first time I drive this thing as the fastest car I've ever driven was this thing running 420 hp and 425 ft/lbs of torque.

To say the least, I'm excited. I miss my S4 and the traction of the AWD, the gorgeous interior and just the all-around Teutonic quality of the car, but this car has a nice feel to it and hits a nice meld of luxury and sportiness as a package. Down the road I'm planning on doing some interior upgrades in terms of tastefully done leather covering of some of the hard surfaces on the dash and door panels to truly bring this car up to a nicer standard overall.

This looks awesome! Can't wait to see some videos of this beast

Is the block a punched out 6.1, or a big block? Good stuff though, what size primaries on the headers? They look like 2" :O

[ENV²]

This. Looks. EPIC

Did you happen to sell you S4 to an older man from NY/NJ? I ran into a guy at the rest area the other day, and he had a goodwood green S4. So i stopped and chatted with the guy for a bit. Said he found it out in Ohio, nad purchased from a guy there?

sick build dude. the 300 is gonna be no joke. hope it will be able to hook up

It's a bored 6.1 block, and the headers are 1 7/8" American Racing Headers SS longtubes.

No, I sold it to some dude in Connecticut who's in his 30's. Ironically, he contacted me a couple of months ago and wanted to sell it back to me. I almost pulled the trigger, but I was buying my Magnum at the time and just didn't have the $$$. I do miss that car pretty bad at times.

The 300C SRT8 has come a long way since that post. Been working with a tuner out of Detroit who works for one of the Detroit car companies. He's really upped the ante with the tunning of the car. Here's a shot of the finished product.

Great to see your updates and progression on the car! Overall, which car do you prefer? This one or the S4?

Curious as to why the guy wanted to sell it back to you?

Well, both cars have their strengths and weaknesses. As any guy here who's gone from a S4 to a RWD car can attest, you end up missing the pure adrenaline of being able to plow the Quattro car into almost any corner without worrying about it breaking away until you hit the limits of the tires. That said, being able to hang the rear out on a 4,200 lb sedan and have it tail-steer between the brake and gas is a rush too. I miss the interior of the Audi, but the later first-gen 300C SRT8's don't have bad interiors either. The power of this thing is mind-bending. I haven't dynoed it yet, but everyone from Arrington Performance to the builder and my tuner are putting it around 680 rwhp. Nice thing about it is that when you drive it gentle it's very well-mannered, but when you open it up it's a freak.

As for the S4, dude needed to buy a truck for his business. I felt bad for him. He really loved the car. He had it pretty much in storage on a lift in his garage and only drove it on the nicest days.

Would love to get a ride in your car if i am ever out in Ohio. What all have you done with it since your last update?

[SRT-OSO]

I bought a full Pedder's suspension kit that needs to go in as well as adjustable lower control arms. The Pedder's kit is every suspension bushing on the car, new sways and fully adjustable coil-overs (rebound and dampening.) I also had American Racing Headers make a new resonator section with beefier resonators. The exhaust is very quiet on the highway without any drone, and it sounds ferocious when opened up, but it was just too ballsy loud at idle for a car like this. I had the idea of building an American AMG when I started the project, and the goal was stealth. The new resonators quieted it down just enough.

Also, any time you find yourself out this way you're welcome to a ride and a drive for yourself. You drive a 911. I trust you with it.

Very few people have ever gotten me to truly want to buy an american car... Every one of those people has shown me a picture simlar to this one lol

Admittedly it's not for everyone. They are big cars compared to the B6/B7 cars, but interestingly, the chassis weight is very close and for a 4,200 lb car, the SRT people did their suspension homework. For an out of the box sporty luxo-cruiser it really handles well, and the brakes are top-notch. I can't wait to redo the suspension. I think it's really going to come into its element then. It's got ferocious power, now the chassis just needs to be re-tuned to match the capabilities of the drivetrain.
