2003 Mini Cooper S (R53) - Fixing creaking interior panels

[Pete-M]

My little Cooper S is in intensive care this week. It's in for a ported big valve head and a 17% smaller pulley. 

Should be good for around 210 bhp, which should make it interesting.

Good to see all the progress you're making with it. It's already running a 15% reduction so it should be even more fun - you might see more of this though!

Just be aware that if you get to more than 18 psi of boost you can run into problems with the MAP sensor.

If your anti-creak methods work, then please come and work at my place, because the only thing more annoying than trim noises is quality specialists banging on about trim noises.

It's not normally the MAP sensor that causes the issues with running smaller pulleys on them but rather the intercooler.  Run a 15% smaller pulley and intake temperatures can just about be controlled by the intercooler. A 17% pulley takes it to the point where intake temp can get too high if thrashed or used on a track day.  19% and the intercooler is needed without fail.  20% and the little Eaton supercharger is right at the red-line. If you run a 20% pulley and take the engine to 7k rpm the supercharger is running at 17k rpm and its days are numbered. 

Mine will be getting a better intercooler, MSD ignition, 380 injectors and a remap. Eventually. 

I'm hoping the sticky Bridgestones will help keep the big yellow light from flashing.  If they don't, then I'll have to fit an LSD.

The idea is to keep it looking as standard as possible, no shouty exhaust etc.
