e55k supercharger bits - cost?

[DavidL]

What does a new pulley/belt tensioner/belts etc cost for an e55? Is it a no brainer to have a smaller pulley and map if you are going to change it anyway?
I know plenty have done this so what's the damage?
Thanks

Hi Dave, There is a big difference in cost! you can just renew the bearing in the supercharger Pulley for £80.00 for OEM Bearing or about £26.00 for a Ebay one thats to DIY which is easy its on youtube, the smaller Pulley is about £450.00 i think, all depends if you think that you need more power

I need to check but I suspect I am being given the price for the whole part mb will want to sell me if the pulley bearings need changing. But as you say just replacing the bearing is entirely possible. A smaller pulley will need setting up too. I gave no real need for more power but then again...
