I am about to fit a -15% Alta v2 pulley to my MCS.

Do I need a reduced belt or will the standard stock one be ok?

If I do need one, where can I get one from?

No, the stock belt will work with the 15% but you might want to replace it anyway since you will have to the old one off.

djwoody · Aug 17th, 2007, 08:10 AM

Yeah think I might. Do you know where I can order one online (in the UK)?

I would contact MINI Coopers by Mini Mania to get a new belt. They should be able to help you out.

I have the 15% alta pulley and usually the new stock belt is fine...however when we tried to fit mine it was flapping around so much before ever being run we ended up putting a reduced one on....but my friend ran his 15% with stock belt and it was not loose when fitted like mine....I think it just depends..on some cars you may require the reduced belt for peace at mind

i think it depends on how old the stock belt is to as they stretch over time like anything rubber

All sorted - I've bought a reduced one from Mini mania.

A bit pricey though - £32 inc delivery.

Thanks all

Agreed.

Hi, yes you should change it but you also use a shorter one. If you use stock length belt then 2 problems arise...Firstly as the belt stretchs the tensioner assembly will hit the stop before it should. Secondly under fast engine acceleration the elastic nature of the belt means again it will hit the stop. Both situations will give slip. The first all the time once its on the stop, the second momentarily.
Even JCW uses a shorter belt and thats with a 11% pulley!
A stock belt will get you by but its far from ideal.....
We include & fit a shorter belt with all GTT conversions.
