Has anyone fitted one to their car? http://liftbars.com/pk.htm#PKsnr

"PKT (PKsn'r/PorKensioner) - advanced 928 timing belt tensioner
Timing belt is always properly tensioned* for less wear on gears, and water pump. Active belt management and real dampening lets the engine run more smoothly and keeps the cams better syncronized. Never needs 'retensioning'. Uses stock timing belt cover (photo).
Sprung/oil dampened tensioner, large steel bushings at all pivots. Pulley is one huge bearing. Less weight than stock! (Stock system = 5.75 lb/2.6 kg, airpump -1.5 lb/0.7 kg, no-airpump -2 lb/0.9 kg + airpump system)
Installed on hundreds of Porsche 928 engines since 2006! Audi sourced tensioner/damper lever and pulley have been used on hundreds of thousands of engines, with millions of miles driven. Components were originally designed for a 105k mile/170k km service interval!
Fits 78-95. (78-79 with 80-up, modified, or no, A/C compressor bracket)"

Which model would I need for a UK 89 S4?

I have one but haven't installed it yet. Email the guy who makes them (Ken I think) and he will make sure you get the correct one for your car. There is a lot of posts about them on the rennlist forum. I didn't see anyone having problems with them when I did my pre purchase checking. The only downside I have read about is that it does away with the tensioner warning system. Theoretically this is no longer needed as the belt should always be properly tensioned, however some claim that the tensioner warning system may give early warning of a pump failure. Parts should however be less likely to fail because the belt is always properly tensioned.

I had the non-air pump one fitted so I could remove the air pump and save weight - great piece of kit - very happy.

Hi Mike - did you still have the Porkensioner?? - I need the part numbers from the 2 Audi components - the bearing wheel and the spring tensioner?

Or if anyone else knows them?

Thanks.
