Mini Cooper S R53 JCW – Airbox Intake Modification

I wanted to replace the stock air pipe, as it contains a resonator which keeps it silent. It’s also not optimised, leaving room for improvement.

Used 2 aluminium joiners/couplers and flexible piping. Very happy with this cost effective result! Also, I love the supercharger whine 🙂

I also ordered a K&N RU-3190 filter, I didn’t know the previous owner fitted a Pipercross PX1875. In the end I sold the K&N as the fitment wasn’t good.

Mini Cooper S R53 JCW – Vacuum Gain System VGS Modification

As usual, the Mini Cooper S with the Eaton M45 supercharger also has a bypass valve, which helps with fuel economy and lighten the load on the supercharger during idling (for instance). On NAM (North American Motoring forum) I noticed a popular mod, which is also known as the VGS or Vacuum Gain System modification.

Basically, the VGS mod changes the way the Bypass valve is operated. From indirect vacuum to direct vacuum, allowing faster response of the butterfly valve, but also keeping it shut better so no boost is lost.

I liked it in the beginning, but it makes for a rough driving experience. So in the end I reverted and never went back. Thats why we experiment 🙂

Volvo S80 2.4T 3rd Brake Light Mod

Bought a long LED strip and mounted it next to the 3rd brake light cluster.

Should be a lot safer and looks good 🙂

Mini Cooper S R53 JCW Heatwrapped Stainless Exhaust

I heatwrapped the new stainless steel Gravity Performance catback exhaust. Unfortunately I ran out of titanium heatwrap, so I ordered some more (black) and finished the job.

It will help with scavenging and is a supporting mod for extracting more horsepower and torque from the Mini.

Volvo S80 2.4T Old Key to Flip Key

Bought a flip key on Aliexpress and went to the key service to get it working. Looks much better and takes less space in pockets etc.

Highly recommended modification!
