Well my car has been down for a bit on account of the Way Motor Works +2% crank pulley I had installed back in Aug '06. I got a good 30+k out of it till Oct. 29th while in the KC area. I had passed it off as a bad pulley bearing but on my way home I was overly curious as to what is actually going on so I pulled off at the Maple Hill gas station on I-70 popped the hood looked down and saw in shock the crank pulley wobbling at idle . I continue my journey home 250 more miles to go and a sweaty forehead on account of the current state of the car. So talking to Brian White about it and he said to look at the tensioner. I did just that and sure enough its failed. Ordered a new tensioner and a new OEM crank pulley . While swapping belt tensioners when I released the belt I heard a rattle and I was just laughing as I was awestruck to THIS
then after finishing it off with a hammer
I also found out from Brian that having a lightweight crank pulley and no matter the size is a contributor to early oil pump failure which results in a oil starved blown motor. So moral of all this stick with the OEM crank pulley if you have a 02-04 swap to the 05-06 crank pulley as its lighter.

Now you need to start asking yourself why your tensioner failed......
BTW, is Brian White with Way Motor Works?
I think having 61k miles on the car and having the oversized crank pulley took the tensioner beyond its engineered specs. Since I am going back to OEM I am going to swap to a 17%.
Brian White is a great friend and MINI tech for South Bay Mini in Cali and also a part of ABF Performance which is (MegaMINI & RMW) he also has the 500whp t-only Black Car formerly known as The Widow.

I think you're right about the pulley screwing up the tensioner, tho I know other's have had to replace them too - I wonder how many of those were running under/oversized pulleys too?
Can't believe you have 61K on your MINI already! That's a pile of driving!

I can't believe it either I turned over 50k near the OK KS border on April 2nd at 11pm. What got me the milage was I drove to phoenix before I went to AMVIV hung out with a few guys there met up with 2 crazy MINI's A 315whp turbo-only MINI which is incomprehensible when you feel the KICK of turbo style boost
