Alu crank pulley.. are they good?

[jondee86]

I have no problem with businesses trying to sell their products, and I
have no problem with people putting products with marginal performance
advantages onto their cars. But I do have a problem with people who
promote their products as being technically sound, when there is a mass
of good engineering evidence to the contrary.

Just to balance things up a bit, here is some information from a harmonic
damper manufacturer, who is also also involved with racing...

While I am sure is is true that NST have many notable successes with
their products; race engines are subject to frequent teardown, and the
replacement of worn or damaged parts. It is also true that sponsored
drivers/car owners are not going to publicize any failure of their sponsors
products. I am well familiar with the car that drops out with an *electrical
failure* caused by a rod that went thru the side of the block and knocked
the starter out of its mountings !!

To say that aluminum pulleys are safe in all cases, is just like saying NOS
is safe in all cases... it is simply not true. And more so for people who are
tempted to install them on their every day driver. I´d just say to anyone
contemplating the use of an aluminum crank pulley, do your homework,
and satisfy yourself that the benefit outweighs the risk. Same thing you
should do with all your mods
