VW - AUDI 1.8T Cylinderhead - Rotationtest 7500 RPM

GT-Power makes a Rotation - Test for the Original 1,8T Camshaft and Valves on the Thyssen Cylinder Head - Dynometer in Germany. All Heads must stand this test before they goes in Production. Lambo, Porsche, Audi R8 and allthe other high tech cars. GTP was the first Tuner which have done this Test, to make sure when comes the critical point in making setups. Chiper and many Tuners just set the Rpm Limiter wherever they belive, but realy nobody knows. Our Customers are not our Testdrivers and this test have to be done, to make sure how high can we run our Power Setups with Turbokits installed !! This High Tec Rotation - Test shows with lasermessurement exactly the valve shattering from the hydraulic valve followers, the valve clearance and how much Rpm you can run save the Engine without the valve hit the pistons under Stress.... 7250 was just safe...... 7500 with hot oilsfoam of older lubriation, the head get under stress and the "hydraulic pushers" start to to jitter. ( it is also a classical engine fold by the Audi RS 4 and S4 ) They dosent work exactly anymore and we have to lower the RPM in the safer Range. We do this Test with a complete new head, new valve guids and new liters. Just imagine, what can happend if you drive your engine with over 80.000 km and older valve guids or older lifters. Ergo you should change them asap Sorry for the bad video quality.
