Audi TT 2.0 TFSi Rolling Road

This Audi TT was brought to us for rolling road checking after having been fitted with a full exhaust system. The car was previously runing a Stage 1 remap prior to the fitting of the exhaust and had been updated with a new piece of software from a hand-held flash tool and the customer wanted to see the results.

After checking on the rolling road it became evident that further enhancements are required to the software due to the throttle closing at higher rpm.

EBC Yellow Pads for Astra J VXR

Astra J GTC VXR models, which have the Brembo 4 pot front calipers and 355mm brake discs now have available the choice of EBC Yellowstuff pads for front and rear.

Available for the front at £128.40 per set, this is a slightly less expensive option for the cost conscious to the currently favoured Brembo Sport HP2000 pad which is receiving excellent reviews and feedback.

The rear pad set is £64.00

Both options are available for online purchase from our website shop.

Astra H VXR Routine Maintenance

Some people are under the impression that we only modify and tune Vauxhalls, but we do also carry out regular maintenance, servicing and repairs.

This modified Astra H VXR was brought to us for a full enhanced service which includes a thorough inspection, an oil and filter change, replacement of the air and pollen filters (or cleaning and re-oiling a high flow panel filter), replacement of the spark plugs with NGK iridiums and a brake fluid change to DOT 5.1 brake fluid. We use OE/OEM filters and high quality Valvoline 5w-40 fully synthetic engine oil.

Additionally at the customer’s request, the rocker cover gasket was replaced as it was leaking. We also replaced the oil filler cap seal which was also leaking and allowing oil to escape, which was picked up during inspection.

During the inspection it was also noted that the factory hydraulic gearbox mount had failed, which is not uncommom, splitting and leaking all its oil and causing the engine/gearbox to move excessively. The mount was replaced and additionally strengthened with a polyurethane insert to help reduce engine/gearbox movement and reduce the likelihood of the mount failing in the future.

VX220 2.2 Upgrades

This very clean low mileage VX220 2.2 came to us for some pre trackday checks and upgrades prior to its owner getting involved in doing some UK track days.

Apart from the obvious fluid changes; oil (5w-40 Fully Synthetic) and filter, brake fluid and gearbox oil (75w-90 Fully Synthetic), the spark plugs were also replaced with NGK platinum plugs. A thorough inspection identified a few other areas that required some work. The rear spring seats/damper collars were corroding quite badly, which is not unusual over time and so were replaced, both side engine mounts had separated and were replaced and an uprated polyurethane insert was fitted to the front engine mount to help reduce engine movement. The header tank had started to crack and degrade, again another quite common issue, so to prevent premature failure on track a new one was fitted.

The brakes pads were getting low and so M1155 brakes pads were fitted front and rear as a starting point. Further attention will be paid to the brakes and suspension as the driver finds his ‘track legs’, so to speak.

To improve performance the ecu was remapped and a K&N Induction kit fitted. One a rolling road set up was carried out we saw results of 156bhp and 163 lb ft torque.

Finally front a rear towing eyes were fitted (essential for trackday use) and a set of Team Dynamics pro Race 1.2 alloy wheels with some trackday tyres finished off the package.

This should prove to be a very good and enjoyable track day car.

Golf Mk5 GTi Remap

A standard Golf Mk5 GTi brought to us for ECU remapping and rolling road set up achieving 240bhp.

Turbosmart Recirculation Valves Now Available

Turbosmart Recirculation Valve

Turbosmart Recirculation Valve

Turbosmart Kompact Shortie Series Recirculation Valves have been specifically designed to suit BorgWarner EFR and KKK turbos.

Unlike the standard, plastic valves that use un-reinforced rubber diaphragms and are known to crack or split under increased boost, the new BW/KKK Kompact valves uses an O-Ring sealed piston which, coupled with their billet aluminium construction give them over 30PSI of boost handling capability.

Designed as a bolt-on direct replacement replacement for the factory valve on all BorgWarner EFR, KKK turbos, the Kompact Shortie Plumb Back provides better boost response and greater boost handling capability.

Included with each Kompact Shortie kit is:

  • 1 x Model Specific Valve
  • 1 x Straight Nipple
  • 1 x Banjo Nipple
  • 3 x Mounting screws

Finished in Black as shown. This recirculation valve is a really nicely machined and finished item, with a quality look and feel about it.

Poly Engine Mount Additions – Astra H VXR and 1.9 CDTi

At our request, Powerflex have added a couple of new polyurethane engine mount inserts to their Astra H range.

Courtenay Sport supplied the relevant OE engine mounts and asked if a lower front engine mount insert for Astra H 1.9 CDTi models and an insert for the Right Hand Side Mount for Astra H VXR and 1.9 CDTi could be produced.

These engine mount inserts fit into and fill the voids in the original bushes and are recommended as a labour saving method of limiting engine movement to improve vehicle performance and reduce the likelihood of engine mount and downpipe failure caused by excessive movement. Some additional NVH may be experienced.

These mounts are now available in both road spec material to reduce engine movement but limit increased Noise, Vibrationand Harshness (NVH) and Black 95 Shore Track spec material, which due to its nature is much stiffer and will lead to significantly more NVH being transmitted.
