Is this still a concern?

Caution: Crankshaft pulley disintegrates at high rpm's? Was looking deep in General discussion and found this. Yay/nay? /ubbthreads/images/graemlins/dunno.gif

Where did that come from? As far as I know stock crank pulleys in GOOD condition are fine for high RPM use. /ubbthreads/images/graemlins/dunno.gif

That pretty much universally happens because the pulley is old.

If you want to be sure, replace with timing belt. Or at least look for dry cracked rubber. It's a two piece dampener pulley.

There are also horror stories out there about running an aftermarket billet pulley - just get another stock replacement pulley/damper if yours shows any uncomfortable signs of age.

Uh? What does the t-belt have to do with the crank pulley falling apart?

^^ He means WHEN you replace the TB swap it ( for comfort ).

Like mention these fail due to age/condition, in fact most every two-piece rubber pulley will separate after awhile.

^^^ Yes. If you replace the pully with your timing belt (aprox 60K miles), then they should never fail. If you race hard core, I've heard of some people replacing everything every 35K miles?!?!?

Derp, I can read. /ubbthreads/images/graemlins/tongue.gif
 

So it should be fed into the TB replacement interval as well?

I did find this.. click

Generally the water pump and probably that pulley are only due every 120K miles and the t-belt every 60K miles, but if your car is far from stock or driven hard, then it isn't a dumb ideal to just do it all every 60K miles.

What's the general consensus on the Fluidampr Crank pulleys?



+1 I'm also wondering about this.

The ATI damper and Fluidamper are nice pieces. They are worth the money (the Fluidamper more so than the ATI damper) if you have the cash to spend for a highly modified motor, otherwise, the stock pulley is sufficient.

I'd say that depends on your goals, the fluidampr probably isn't better at very high RPM due to the way the fluid dampening behaves, but it's what, half the cost? If I were building something crazy I'd go with the ATI based on all the research I've done, but frankly there've been a ton of stock damper 1000hp cars (well relatively speaking) so I'm not that worried for as weenie as my goals are /ubbthreads/images/graemlins/laugh.gif

There have also been a lot of lower horsepower cars that have thrown apart new stock dampers in a short period of time.

It's hit or miss, try out the stock unit, if it doesn't hold up, buy the Fluidamper. I'll bet the stock piece works just fine.
