The 2.0 Diesel N47 Engine found in most of the E Series BMWs is very tuneable, but not as bullet proof as it's 3.0 cousin, as we found out a while back. Over the last few months we have been developing our upgrades for the N47 / N47N Engines found in the x16d / x18d Models. These have a Solenoid Type Injector that are very small, and struggles to do much over 200bhp without excessive smoke and Exhaust Gas Temperatures (EGTs) This Blog Post is specifically talking about the x16d / x18d N47 / …

If you're subscribed to our YouTube channel, you may have already seen the series of videos we made on tuning the 3.0 V6 Amarok. If not, don't worry, this blog will cover all the bases! Or, you can still watch the videos here: From the beginning: This project all came about after a customer contacted us regarding tuning his pre-ordered brand new 258bhp VW Amarok. His brief was simple. 400bhp and 60mph in ~4.5s!   Suprisingly VW made things easy when it comes to the engines fitted in the …

Something a little different to what we normally do race wise, we decided early on in the year to enter the 750 Motor Club Birkett 6 Hour Relay Race which takes place every year at the end of October on the Silverstone GP Circuit.Instead of a straight race or normal endurance format, the relay element is for the driver AND car. Basically, a car and driver goes out, does their stint (which can be anything from 1 lap up to 3hrs of driving), and when they come back in the pits, a second car and d …

So its been a while since the last A5 video due to other projects but you'll be glad to know we are still working on this project slowly but surely! Check out UPDATE of our Vlog below: And then, not a massive update, but our new, bigger big turbo has arrived, so we talk through the specs and run the car up on the Dyno before we start to rip it to bits again. Full A5 spec list and links to the products we fit throughout the build - http://drksi.de/AudiA5 You can also enter the competiti …

This one blog is summarising 2 Video's of our Audi A5 3.0 TDI Project! Part 14 and 14.2. Back in Part 8 we travelled over to John Sleath Race Cars to carry out a series of upgrades on our car whilst on the dyno, taking it from 228bhp - 340bhp in the same day. Since then a lot has been happening, and not just with the car... We have recently purchased our own 4WD Dyno Dynamics rolling road. This is something we have had planned for a while but when one came up at the right money we could not r …

Part 5 of our A5 BuildWe are now on to the Exhaust System. This is a common modification our customers do, both from a performance, aesthetic and acoustic perspective.A quick look at the stock exhaust, it is 65mm (~2.5") to 55mm (~2.15") and has 2 small boxes right at the back, but is still pretty quiet as the DPF is also a large silencer. It also has twin 3" Rolled Slash Cut Tips as standard. The standard grade of stainless is very poor and we see a lot of cars with rusty ex …
