I have an 02 A6 4.2 Sport and was informed by PES that they would be able to ship me their new supercharger in 16-18 weeks. (by pre-paying). Im basically wondering what needs to be done with the engine and transmition? Cam shaft, drive tran, anything at all that needs to be replaced with upgraded parts so it can handle the increased HP easy. I definatly dont want to break anything or stress any parts out. suggestions?

 

The kits should be designed to not break anything, but their latest 3.0 SC revision has spoken otherwise.

There isn't anything specific that should be prepped, just have your maintenance caught up 110%, incl any leaks and fresh oil changes.

Excited to see some real pictures/footage of this baby in action!

 

I don't know what hp increase in claimed (it's almost 50% from my normal-aspirated Crossfire to my SRT6 with a s/c), but any significant increase is going to put a strain on the drive train. Be prepared to rebuild the transmission (specifically torque converter) and you could strain and prematurely wear the CV joints.

Make sure your brakes are good. Accelerate harder = stop harder.

 

The 4.2L torque converter and trans is built a lot stronger than the 2.7T. You have to remember that germans tend to over engineer everything, since the 4.2L was their flagship A6, it got all the best drive train componets. I wouldn't be suprised if it could handle 600 horsepower without breaking anything. Way more power than that S/C could put out. It shouldn't be a problem. Im just guessing here, but since i have replaced torque converters on both the 2.7T and 4.2L, i would say the 4.2L's converter can handle 30% more than the 2.7T.

 

When I see it, I might believe it. I've been hearing/seeing this on their website since 2007.

 

MTM has a supercharger for the 4.2 in the C6 and it will only set you back about $23,000. So far I have passed on making the upgrade to 450 hp. I am instead going with a Unitronic chip for $600, which will bring me to 355 hp and 335 torque.

 

I was surprised to get an email from PES about the SC G4. Even on the more aggressive settings they are advertising a 30-40% increase in power. I might copy and paste the email here for further details.

 

Latest developments on the G4 Supercharger for the Audi/VW 4.2L engine group

11.25.08

Production tooling has officially begun! We will be delivering complete production units in March, 2009. The systems will be available in 2 stages for all of the 5V multi port fuel injected engines which include the Audi S4, A6, A8, Allroad, and VW Touareg.

STAGE 1 will be a low boost (5psi) kit with a power increase of approx 20% over stock. The expected retail price is $6,495.

STAGE 2 will be an intercooled version with 8psi with a air - liquid intercooler system producing a power increase of approx 30-40%. The intercooled version will retail at approx. $8,495.

The base system is designed so that it may be upgraded easily to the intercolled version at any time. The intercooler core is inserted into the top of the intake manifold by simply removing the manifold cover plate. The system will include the intercooler core which is nestled into the intake manifold, a heat exchanger which sits behind the bumper cover, a Bosch high flow pump, innovative brackets to attach the pump to the intake manifold, an OEM quality coolant reservoir/expansion tank, plus all the hoses, fittings, and wiring needed to complete the installation.

With the worldwide interest in this product (especially at the price point) we are expecting demand to exceed supply for our initial production run. For that reason we are offering a special promotional offer to those who would like to "secure" the purchase of their kit now. Pre-production orders are now available at the reduced price of $5,995 for the non-intercooled kit and $7,995 for the intercooled kit. A non-refundable deposit of 50% is required to receive this special offer.

The G4 design began using 3 company owned vehicles. A 2001 A6 4.2, A 2005 S4 4.2, and a 2006 A8 4.2. While we still own the S4 and the A6. The A8 was sold. We are seeking cooperation of individuals with the following models/years so that we may test fit the system and custom taylor the ECU tuning to vehicles of model years not stated above. Most likely everything will fit perfectly, as the engines are all essentially the same, but we want to be 100% sure. Your cooperation can be your gain as we will be offering free installation to individuals ready, willing, and able to work with us. You can have a supercharger system installed and tuned on your car by PES for a mere $5995!
