After using the car in standard form for a few months, I decided that I needed more power and better handling to go with the comfort, extras and space offered by this model.

I have been modifying my cars for the last 20 years, having purchased a variety of British, German and Japanese vehicles including some JDM special editions.

The modifications ranged from simple remaps to adding turbochargers or swapping engines from different models.

The Superb is our family car and, thus, I was looking at modifications that would not affect the way the car behaved, so hard or overly low suspension, extreme visual changes, loud exhausts or anything that would seriously compromise reliability was not an option.

The first modification was to be a tuning box from a company I used in the past. I will not mention the name as I did run into some problems with it and I do not wish this post to sound like a complain towards them as they did their best to rectify the issue, alas unsuccessfully. The tuning box did indeed increase power, as you will see below but it also introduced an uneven idle which was why I had to return it in the end for a refund.

The tuning box and the Turbo technics large bore intake hose increased the power to 318.5 hp and 301.6 ft/lbs (323ps and 408nm). The mid-range felt quite a bit more torquey and the car was faster overall.

NOTE: Through this process two different dynos have been used, I had the car tested, using the same configuration, on both dynos and the results were within a couple % of each other so for the purpose of this thread we will assume the results of these dynos to be comparable, as comparable dynos results can be (this is a story for another thread!).



Racelogic vbox was used for measuring the car’s performance as well as a few ¼ mile runs at the drag strip (both Shakespeare Raceway and Santa Pod).

SUPERB (280ps) 0-60mph: 5.1s 0-62mph: 5.4s ¼ mile: ???

SUPERB (323ps) 0-60mph: 4.7s 0-62mph: 5.1s ¼ mile: 12.88s @ 106.43 mph

The next step was to try an aftermarket intake. I chose to purchase and test the ARP carbon intake as I liked the way it looked and most reviews were positive. This increased power to 331ps which was a welcome increase but not especially good value for money compared to the tuning box and intake hose.

After returning the first tuning box I decided to try a different one from a German company, the Racechip Ultimate. Unlike the first box this did not affect the idle negatively while also giving the user the ability to switch between different maps using either an Android phone or an iPhone. The maps are downloaded from the company’s server and, importantly, can be modified to increase or reduce power accordingly depending on each car’s characteristics. After a few tests and tweaks the best result I could get from the Racechip was 340ps.

SUPERB (340ps) 0-60mph: 4.6s 0-62mph: 4.9s ¼ mile: ???

After testing both tuning boxes I was offered the opportunity to test another similar box, Burgertuning’s JB1, albeit one that could control, in addition to boost, the car’s fuel pressure. According to other users, this allowed the car to run even more safely and produce more power. In addition to the above, JB1 also allows the user much more control over the car’s boost giving the option to modify the additional boost in increments of 0.2psi based on the RPM range. This provides both a more smooth acceleration as well as more control for manual gearbox users that want to avoid clutch slip.

Using MAP 1 at 5.2 (adding 5.2psi to factory boost) the Superb now produced 345ps and acceleration improved more than what the extra 5ps would suggest due to the better power delivery of the JB1 box.

SUPERB (345ps) 0-60mph: 4.3s 0-62mph: 4.6s ¼ mile: ???

Having decided to move from Stage 1 to Stage 2 I ordered a Forge intercooler and a BCS/Powervalve downpipe with a sport catalyst. This would allow more power and faster turbo spool while retaining delivery smoothness and keep inlet and oil temperatures down despite the extra boost. The intercooler and downpipe allowed me to use +5.8 psi on the JB1 and also tweak MAP 6 (which allows the user to specify the additional boost for every 1,000RPM range).

This increased power to 368ps and made the power delivery much more flexible. Acceleration improved accordingly.

SUPERB (368ps) 0-60mph: 4.2s 0-62mph: 4.5s ¼ mile: 12.52s @ 111.05 mph



I had decided to stick with stage 2+ until I was offered a hybrid turbo at a price I could not refuse. As I already had a lot of the bolt-ons needed to move to stage 3 I decided to take the plunge. I purchased the Turbo Engineers’ TTE525 turbo and started planning my next steps. VRS Performance installed the turbo and ancillaries.

Still using the factory cat-back exhaust but changing the spark plugs to 1 step colder ones (NGK R7437-8 IRIDIUM), the ECU was mapped by MRC tuning, along with the DSG box, producing 453.8hp and 415.7 lb/s (460ps and 564nm).

SUPERB (460ps) 0-60mph: 3.7s 0-62mph: 3.9s ¼ mile: 12.02s @ 114.68 mph

Next step was a custom cat back exhaust. Not wanting the car to become very loud, being a family vehicle, I decided to choose a professional company that makes custom exhausts for Aston Martins, RS Fabrications. Their systems are of excellent quality while both retaining low noise levels and allowing maximum power with minimal restrictions. This new and improved exhaust in combination with a 5.5 inch catalyst (compared to the 4.5 inch one I had before) designed for the RS3 and TT-RS and tested to more than 600ps allowed the Superb to make a very impressive 519.7ps and 686nm for the drag strip! A more conservative 506ps (500bhp) map is used for everyday purposes to cater for fuel quality variations. An Autotech Uprated High Pressure fuel pump was installed for increased reliability. The ARP air intake was replaced with a VWR 600 intake. The NGK R7437-8 spark plugs were replaced with the NGK R7437-9s, which are a step colder.



This allowed for a very impressive 11.46 ¼ mile, a time comparable to the time of a Lamborghini Huracan

SUPERB (520ps) 0-60mph: 3.27s 0-62mph: 3.47s ¼ mile: 11.46s @ 120.28 mph



543ps with Wagner intercooler



Full exhaust, great job from RS Fabrications!

i'm sure someone else posted on here the similar bhp. Very good but i have to ask why not just get a c63 or similar which are more drivers cars?

4WD, more leg room and boot space. Cheaper (even after mods) than a brand new C63 (or, actually, the E63 which would be the equivalent),
And very importantly Different (always liked that), and a sleeper.

Of course different people have different requirements and wishes for their car and I absolutely respect that!

Given you didn't want to firm up the suspension, can you actually use much of the power other than on a drag strip in a straight line?

it was more these are about 34k new with 10k mods, that sort of of ballpark gets you a c63 a couple years old with warranty, but you answered the question.
The superb definitely looks interesting, and it was briskoda i saw the thread not here.
Are you going to go higher than 543 bhp?

At the moment it is 560.
Yes, it will soon be 600+

The eibach lowering springs and anti-roll bars made a huge difference. The uprated mounts also helped.

Along with the adaptive suspension set at Sport (has 3 levels) and the haldex 4x4 it drives surprisingly well for a car that big on B roads.

Note: The haldex and electronic differential were also tweaked through VCDS to the more extreme settings.

In D gearbox mode and Normal or Comfort suspension setting it does extremely well.

This is SUPERB (sorry). Seriously impressive from a 2.0. How long will it last? What are the gearboxes/transmissions like at this level of torque?

I know from bitter experience how it feels (and the expense) to blow up a heavily modified car so interested in the reliability aspect:

I've heard rumours, rightly or wrongly, that the boxes tend to be the weak link on them, which, after running a near faultless Lexus for 6 years, has put me off the idea a bit. Is that all it is, internet rumours? I would have thought yours would have shown any inherent weakness by now with what you've done to the engine? I'd have one in a heartbeat if they hang together.

Clutch is good up to 550ish but I changed to APR clutch pack anyway which is good to much more.
Gearbox is very strong, a couple of Golf R's with the same gearbox will be running well over 700 soon
