i was talking to my friend about a pulley and he siad it is not a good idea. that they cause alot of virbrations an cuase alot of wear and tear aon the engine and not worth hurting ur engine
are they really safe to wear u can use the engine to 200k ? or do the cause wear?

 

First off, about 1 in every 2 RA owners here on Evom (est.) own the RRM Pulley and not once have I seen someone make regards to an issue with the pulley. View the link I have provided.

The pulley that was designed for us was researched and tested and is well constructed.

 

well there r ppl here with 80k miles with pulley and keep going good...mine has 25k with pulley and no problems till date the car still runs great...

 

I Would of bought pulleys but from I read and have been told by mechanics, I would not recommend buying them.

 

No problem with mine either!!!

 

It's fine. Mine has been on my car for over 60,000 miles and everything runs like it was new. Also, remember that the flywheel side of the engine has NO damping at all, and it's not needed on the front of the engine, either. Our crankshafts are well balanced. If they weren't, no way a pulley with a thin layer of rubber would save them.

 

mine is great and I run nos ,but if vibrations are going to hurt the motor , motor mounts are equal to a death sentence......and if your worried about it breaking something in 200k, regardless something is going to break and/or fall apart in 200k,I mean come on...

 

^ so true

 

its a nice piece, i put one on about a month ago and really like, i have noticed nothing in the way of vibrations etc and i am pretty picky about such things, dealership even had good things to say about the thing!

 

65,000 miles on my car and over 50k with the UDP and there 's no vibration on the engine
