Question Light weight pulleys??

Not sure exactly how much will improve on performance, but saving weight and looking good is a key factor for any performance car, so go for it, life's too short........:-)

With a lightweight flywheel you will notice a difference with throttle response. With just the pulleys by themselves I'm not sure. Will freshen the look of your engine bay tho. The RCM ones look super nice.

You'll not see any difference in performance.
I have a set, underdriven, bought when my crankshaft pulley started to fall apart

do light weight crank pullies not cause excessive vibration leading to engine wear? or is this a myth?

They look good and compared to the standard pulleys are well light when you change them take a feel of how light they are compared to the Lardey originals and that must help with rotational inertia not much but something it all adds up.SJ.

I have been running light weight pulleys since 2004 and have never had any problems what so ever,so I guess there is more scaremongering myth then truth.SJ.

Not sure which pullies you are reffering to, but if you are talking about the aux pullies, then just some advice. lightweight usually means alloy, when alloy and steel get together and start to corrode their bond is very strong. I brought a car with ally pullies and needed a cambelt change. The enginer tuner broke 3 snap on bits and needed an 18ft scaffold pole to get the crank bolt out, after heating and cooling, due to the crank bolt essencially welding itself to the ally pully. My advice, stick to the original ones, if you want to spend money, get them cleaned up, maybe polish the areas for good looks maybe paint those bits that are not in contact with the belt, but don't replace.

Just my experince, feel free to ignor! But it was almost a case of not being able to undo the crank bolt!

A steel crank bolt threaded into a steel crank up against an anodised piece of aluminium shouldn't give that much of a problem, certainly it's not really something I've encountered? Did you get a look at the surface of the pulley or the bolt itself once it was out?
