5 series E39 Underdrive Pulleys

[Silver Bullet]

Hello everyone,

I am new to the club. I need some advise here.
I am exploring to replace the under drive pulleys, if you have any experience please drop a line or two with regards to the performance gained. Some manufactures claimed the replacement can generate some free horse power gained up to 10 BHP.

Perhaps you can share your views,

Thank you and regards

Silver Bullet,

Hello and welcome to the community! We have some members here who swear by UUC underdrive pullies, and i myself have used pullies on my ex E46 3 series.

It is one of the more popular modifications which is a simple bolt on affair.

I've written a review of my installation here.. http://www.bmw-sg.com/forums/showthread.php?t=77

A little old but the concept still sticks Hope to see you at our upcoming meetup! It's this sunday..

You should go ahead and get it done. Had it on my E39 and it makes a world of difference. No ill effects at all.
