ATI racing Aluminum crank pulley "Balancer?"
 

Hey I was skimming through a magazine earlier this morning and I found this

http://www.atiperformanceproducts.co.../damnissan.htm

Although it doesn't show it for the KA, the Advertisement advertises them as "NEW!!!"

Now I know a big problem with replacing the front crack pulley is due to the fact that it eliminates the Harmonic Balancer, but apparently this one incorporates it....

next question...is it worth the money??? The Ad says that they sell for $530...what do u guys think?

There pulley isn't aluminum. It will however increase/improve high RPM power.
They have the KA on file, the same dampener that is on file for the SOHC is the same that they use for the DOCH KA (for crank harmonics). They have made the SOHC dampener for GT3 SCCA engines for over 10 years.

You might want to do a little googling before you buy... That price is a bit high if you ask me.

yeah that's what my buddy was saying too...i personally wouldn't...i have no real need for it. That's money better spent on tires IMO

I can back up that (ATI DAMPENER) it will make more high end power than an aluminum pulley would....
Aluminum pulleys show on AVG a 3 WHP gain on a KA.
ATI Dampeners I've seen gain as high as 9WHP on a KA.
Maybe pricey but it does do wonders on wheel power.
