An Audi S5 is a great car, but everything is better with forced induction! To test that statement on this S5, we installed APR's supercharger kit and we were not disappointed. To make sure the additional power wouldn't result in a prematurely worn out clutch, we installed a DXD clutch disk with a new OE pressure plate.

All that new power, there was no way brakes weren't on the checklist. Brembo was the first place to go. They're used on the street and across motor sports so for a car that is used for both daily driving and tracking, they're a perfect choice.

We have a little extra go, a little extra stop. All that was left was a little extra show. But with a car as gorgeous as the S5, where is there any room for improvement? The answer, of course, was wheels. We set this Audi up with some BBS CH-Rs and it is now beautifully prepared for anything.

To the build!

First things first, getting all the parts out of the box and ready to go.


The 44lb chunk of aluminum that nets this car a 150hp gain! For the record, it is only a 26lb increase over the stock manifold.

Now the real fun begins. Its time to get the supercharger in place.

During the supercharger installation, we discovered that this engine had a severe carbon build up in the intake ports. This is a common problem in direct injection engines since there is no fuel in the intake to wash away the deposits as they form. The only way to completely clean these ports is to remove the cylinder heads which is approximately 30 hours of labor that starts with removing the engine from the car. But by carefully manually cleaning the ports with solvents and dentistry tools, we removed the vast majority of the build up.

To show you just how bad this issue can be, here's some shots of the cylinders before cleaning.




Slow and careful cleaning



And after cleaning





With this finished, looking a lot better, and the supercharger installed, we were good to move on to the next steps.

Clutch and Brakes

Each DXD clutch is designed to match specific styles and for this S5, we chose endurance. A great option for cars that see track time in the form of longer racing styles, it was developed with APR Motorsport to support their efforts in Grand-Am road racing. The Endurance configuration focuses on reduced transmission wear and perfect transitions from gear to gear. Track time aside, it works wonders for a car with high power that needs a clutch that will keep up with it for the long haul.

The stock versus the new DXD


And speaking of track time, high power and long hauls, we can't neglect something as important as the brakes. Brembo is a trusted brand and we see quite a lot of big brake kits come through our doors. This Audi will definitely put them through their paces, both on and off the track. Not to mention, they look pretty great too.

Stock brakes



When sitting side by side, there is definitely a noticeable difference



Brembos installed



This Audi was almost complete. Wheels are a usual go-to when its time to personalize your ride on the outside. Having seen this style BBS wheel on our shop A5, this customer wanted some for his S5. In the titanium finish, we think they're an excellent way to complete this project.

Nice!

 

Wow that carbon build up is pretty nasty!!! Any way to prevent or treat without pulling the manifolds?

Car looks amazing! Any power numbers or 60-130 times?

 

You guys do some nice work! Just wish you were closer to MD.

 

Thanks! We have private transport available Also, we have a number of clients that drive down and fly home and then fly back to pickup the car. We are 10 minutes from the Charlotte airport.

 

Those are the brakes that should have come on that car!

 

ditto the last comment!

 

They definitely made a nice upgrade.

 

Very nice

 

Thanks! This car will be at the track for our annual Fall track day if anybody would wants to come by and see it.

 

Hey guys! Just stopping by to share a few shots from a recent photo shoot we did of this gorgeous S5. Let us know what you think!

 

Great work, I really love the front of that S5 and the red seats.
