As we plan to run our A5 on the track and have a trip to Spa and the Nurburgring planned in a few weeks time, we thought it wise to install at least a half roll cage, and from past track car experience, we wanted bucket seats and harnesses too to stops us sliding around! We had a look online and nothing that was easily obtainable (most cages were in the USA) or reasonably priced, so we decided to speak to Matt at Slide Motorsport, as they made the cage in our BMW. After a bit of discussion we …

Some subscribers to our YouTube channel will have already watched the 2 part series on tuning the latest 2.0 engine VW have to offer Part 1 Part 2 We find the Mk7 / MQB Platform 184 models with the CUNA or CUNA Engine code usually produce between 170 and 180bhp on our dyno in standard form. The GTD in the videos made 170bhp when flashed back to stock, 177bhp on an updated stock file, 188bhp with previous old tune that quoted 230bhp and then 209bhp with our custom r …

We have posted many Blogs in the past, showing videos and images from our Racelogic VBOX HD2, but figured it would be a good idea to explain how we use the system in pursuit of faster lap times. Check out our blog on Using a Racelogic VBOX HD2 for Tyre Testing to see how we use the VBOX when comparing different tyres. This time, we are concentrating on Driving Technique. A saying someone told me, which I think is quite true:'When looking to shave time off your laps, you can find hundredths of …

On first inspection of our Audi A5 we found some excessive play in the front drive flange cup. We initially suspected bearing wear but after removing the gearbox we found the problem to be something else... Whilst the gearbox was out and the fact it wasn't a 2 minute job to do so, we also decided to replace the Flywheel for a new unit. Another issue that we addressed at the same time was oil starvation causing clutch slip. Under hard acceleration oil is pushed to the back of the gearbox and awa …

We have posted many Blogs in the past, showing videos and images from our Racelogic VBOX HD2, but figured it would be a good idea to explain how we use the system in pursuit of faster lap times.Other than changing the driver (which can make a huge difference!), another important factor is the Tyre choice. We currently race in the MSV Trackday Championship and MSV Trackday Trophy. In the TDC, Tyres must be Toyo R888R (GG Compound) or R888R, whereas in the TDT, they can be from the Motorspor …

In Part 10 of our A5 vlog we perform our own custom Gearbox tune while measuring before and after 0-60mph times using our Racelogic Performance Box to see what difference this makes in the real world. The V-Box showed 4.74s on stock gearbox software and after some magic we managed 4.42s to 60mph with our custom tuned gearbox software. With some fine tuning we would expect to drop below the 4s mark and into serious supercar territory. We were utilising our DL501 Stage 2 software at this power le …

The M57 is a water-cooled and turbocharged inline six cylinder diesel engine with common-rail injection. It is based on its predecessor, the M51, which was a six-cylinder diesel engine with a Bosch VP20 swirl chamber (in-Direct) injection or IDI as its commonly known, and was fitted to the E34 to E39 td and tds models. The block and the crankcase of the first M57 engines and the TÜ (Technische Überarbeitung = revision) engines are made of cast iron, TÜ2 engines are made of alumini …

A different start to the day for the A5 project. As our Dyno Dynamics 2WD system is not capable of running the Torsen Quattro, Ryan, James, Paul and Danny set off to meet up with our friend John Sleath - http://www.john-sleath.com/ - in Doncaster. We used John's dyno many times when Darkside Developments first started and the now infamous Jetta's 300bhp graph was produced there. John saw the development of that project from start to finish and was always impressed with the figures and reli …
