Mini Cooper S R53 JCW – Servicing the Eaton M45 supercharger

When I bought the Mini, it had reached the 160.000km or 100.000 miles mark. This is a milestone in the Mini Cooper S service history, because it means that you need to service the Eaton M45 supercharger (new fresh supercharger oil etc etc).

I saw the episode from Wheeler Dealers and felt confident. It was a lot of work, but fortunately it wasn’t complex. As this isn’t my daily driver, I meant I could take the time.

Finally cracked the supercharger open to allow for visual inspection of the gears (they looked good!)

I also replaced the supercharger coupler with a new oil filled nylon coupler (in red).

Volvo S80 2.4T Dirty / Clean Turbo Coldside

Replaced the air filter and the turbo intake pipe. Please note that a dirty intake might also point out a badly functioning PCV system!

The intake pipe was upgraded to a blue Do88.se / Do88 silicone intake pipe, which is a fair bit larger, but also deletes some bottlenecks from the original part (like the narrowing bend on the bottom and the “harmonica”).

Gives a little bit more power from the butt dyno and noticed more intake growl (which is a good thing) 🙂

Replaced the air filter. This is what a dirty airfilter looks like.

Change it on time, so your car keeps performing at peak efficiency!

VW Golf MK3 GTI, New Fuel Pump

As the car is about 21 years old, it was about time the fuel pump was renewed. A fuel pump gets old and will be unable to deliver the desired fuel pressure when needed. This will have a big impact on the performance as you might imagine. It took me quite some time as the retaining ring was stuck, like real stuck…

I was finally able to prise it of, but needed to perform some cleaning before putting in the new pump. But it was worth it!
