T5.1 2.0 Common Rail VW Transporters make up a high percentage of the vehicles we deal with. We tune many 2.0 TDI CR 84 / 102 / 140 bhp models. All of these models have pretty much the same hardware and are capable of similar results, however the limiting factor on the 84 / 102 variants is the 5 speed gearbox.From prior testing we have found the 02Z 5 speed gearbox is not much use over 200bhp / 330lb/ft on these vehicles. This is providing you can find a clutch and flywheel to handle the power. …

You may find yourself reading this because you are in the unfortunate position of having con-rod failure on a BLS / BXE Engine. This issue is proving to be very common, we receive multiple phone calls and emails per week in relation to this. Rather than replace the failed block with like for like we recommend installing the ASZ PD130 / ARL PD150 engine from MK4 platform A quick glance on Ebay will show how overpriced BLS / BXE engines are due to the high demand. In comparison a PD130/150 engin …

1. What are the benefits of Water/Methanol injection?Greatly reduced EGTs - Decreases of 250 degrees F are common using a 50/50 water/methanol mix. Increased EGTs are an engine killer in today's performance diesel world. Low cost power - Beyond a remap, where else can you get 10-20 BHP for as low as £440? What other modification does all these things with one system? Greatly increased air charge densities - 3-5 psi boost increases are common with liquid intercooling. Decreased emissions - increa …

Round 6 of the MSV Trackday Trophy on Sunday 30th September 2018 in our Ibiza took us to Rockingham in Corby, Northamptonshire We were testing on the Friday, which I wrote about here.After scratching our heads trying to work out why tyre temps were so crazy, we decided to remove the Gurneys on the front bumper. These were fitted to reduce airflow over the tyres, as the turbulence is bad for Aerodynamics. However, we thought that the benefit of getting air over the tyres would be greater tha …

With the success of Round 5 of the MSV Trackday Championship a distant memory, and us ineligible to enter Round 6 as it requires an MSA National A licence (we are still a couple away from the 6 signatures to upgrade our B to an A), we decided to enter the Rockingham round of the MSV Trackday Trophy instead. The rules are pretty much the same as the TDC, so our Ibiza was in Class B again. The main difference are the allowed Tyres. The TDC requires everyone to be on the same Toyo R888R GG Compoun …

OIL CONTAMINATION What causes oil contamination? If the oil filter is blocked/damaged or a poor quality oil filter is used Excess moisture can lead to premature oil degradation High carbon build up in the engine can quickly contaminate new oil Alternatively, if oil levels are too low or if the wrong grade of oil is used, the turbocharger can prematurely fail. Turbo failure prevention: Using new oil and filters helps to reduce the risk Replacement oil must be the correct grade …

Below is a brief rundown of the major build we were involved in for the SRS Automotive - Caddy Van. The vehicle has been in the family for quite a few years now, coming to us with a blown BLS Engine (rod through the block - standard!). We swapped in a 2.0 16v PD BKD Engine, initially tuning it to 220bhp & 350Ft/lbs, but finishing off with 340bhp & 435Ft/lbs before Stef decided he wanted to get some Common Rail DSG action! The build started in September 2017. The Engine was ripped …

The end of the summer brought us to one of the biggest VAG Shows at Santa Pod Raceway in Northampton, VW Action 2018. VW Action has always been a great show for us, both from a spectator perspective and for results. It was where we did our best time in the Arosa last year, a 9.7224s @ 146.74mph and Jerome also set his quickest time of 11.183 @ 121.88mph in his Ibiza, so we had high hopes for both cars performing well this year. Saturday The day started out in th …

In 1999, Volkswagen introduced what would become one of the most well known engine designs of modern times - the Pumpe Duse (PD) diesel engine. In a departure from many of its rivals, the PD used unit injectors rather than a common rail system, despite most manufacturers thinking that common rail was the better design. Volkswagen proved them wrong for many years, with these strong, reliable, powerful and economical engines being a huge part of what made diesel cars popular. Their 2000 BAR pea …
