My 04 MCS has a little electric rattle sound when accelerate at 3-5K rpm. Sounds like the crank pulley need to be replace. Anyone used Alta 0% crank pulley? If so what are the bad and good? According to Alta website they said no harm to engine internal. Also I have the 15% Alta pulley. You opinion is appreciated. Thanks in advance.

 

It's not dampened which can hurt the engine in the long run. Go with the ATI instead.

 

What Vkng said. Everyone I know who's had to replace the crank pulley goes with the 0% ATI dampened pulley, and has been very happy they did.

 

Thanks guys. I've been doing a lot of research and hearing ATI 0% has more positive reviews than the light weight crank pulley. I will go with the ATI just to be safe.

 

I'm running a 2% ATI w/ a WMW 15%. Runs ( smooth)like new on my 02 S.

 

I've got a lightweight pulley, revs a bit quicker with it. It's a solid design, (as in no spokes) 0%, did a lot of research and talked to many BMW guys before making my decision. Car runs like a top with no vibrations.

 

How long has been? Any over heating issues?

 

What brand? your tempting me here. I want to keep this car for a long time. Will be passing it down to my boys for their high school car.

 

Check in his sig. Looks like Ireland Engineering.

 

I hear you, it's my daily and I need mine for a long time also. I messaged a lot of guys on this forum who ran them for tens of thousands of miles without issues. There's a guy on here who helped develop the tritech who commented on the question.

 

Gotcha!

 

Nice...Thanks for the attachment. I can't find the 2%. Just the 4% I think it would be over kill no?

 

Besides ATI pulleys. How about these? Of the three which is the best? Thanks.

Never mind...I got it! Thanks.

 

I found your IE pulley. The price is so tempting! Got to sleep on this.

 

notice it's identical to cravens peeds

 

Hey guys, people have gone over this before, but it has been proven again and again that a solid crank pulley is fine to run on the MINI R53. We've been selling these for well over 10 years, and have had customers drive on them for hundreds of thousands of miles and I haven't heard of anyone have any problems with their engines. If you guys want, I can probably dig up the original thread about it!

 

I've got an Alta 2% I never installed. Anybody wanna give me something for it?
