VOSA Approved Test

VW Golf

These tests were carried out at Unit 33, Sugarbrook Road, Aston Fields Industrial Estate, Bromsgrove, B60 3DN, England, on September 16th 2008.

Tests carried out using Bosch 350 callibrated Diesel Smoke tester and Rotronics Dynometer.

Vehicle: VW Golf PK51EWJ
Mileage: 118000m
YOM: 2001
Varient: 1.9d 130hp

The European Law allows a level of upto 0.64 for this vehicle, but, as you can see, this being a highly efficient engine already the output is only 0.10.

The first run on this car gave a power reading of 132.62hp and 228.7lbft torque on the dynometer and emissions of 0.00 on ZERO DRIFT and 0.10 in both mean value and FPT mean value.

As you can see, the test is completed under EU and UK specification of emissions control.

After the tests we allowed 2.5 hours for the engine to cool in a temperature controlled cell at 17.8 degrees. After this time we inserted Oxytane at the correct ratio and then allowed the car to run at idle for 20 minutes.

At this point the engine was at peak running temperature and the same level as the original test so we first ran the car on the dynometer, the car gave an instant boost in throttle responce as well as a gain in power across the rev range with a high level of gain between 3300rpm and 4100rpm with a maximum yield of 2.8hp.

After this test we again allowed the car to return to peak engine temperature and ran the emissions checks. This is where we noticed what can only be described as astonishing results, a drop in emissions of 40% from 0.10 to 0.06.

Not only that, the engine also had a noticeably reduced engine sound.
This is the largest drop we have seen of any product tested outside of ECU control.


The end result of this product is a proven gain in horse-power, a 40% reduction in emissions and lower engine sound.
