2005 JCW Challange - oil grade and supercharger whine

[simon clark]

Morning all,

I have recently bought a 2005 Mini Cooper S JCW Challange (original factory built race car) which is pretty standard except the GP Intercooler.

I have already done a 3 track/test days and am going to race next year, probably in the Trackday Throphy.

A couple of questions, firstly what oil should I be using - I haven't got a manual with the car..

and secondly, the car doesn't make the typical supercharger whine at all. It's really strange and just sounds like a normally aspirated car but is definately supercharged and makes all it's claimed power. Any thoughts?

Cheers

Simon

[simon clark]

thanks but which grade of oil would you use?

[simon clark]

Thanks!

Do you recommend a Supercharger oil change because i've said it doesn't whine? is there a correlation?

Cheers

Simon
