Unorthodox ss pulley set?

[jdm93dsm]

anyone know anything about these. if they are worth the $$, i found a set for 100$.

"These gains are obtained in two ways. First, and most important, is the weight loss. There is an average of 2.7 HP gained from every pound lost off the crank shaft. With the lighter accessory pulleys, as much as 15% to 30% more power can be found. 85% of our gains are from weight loss."

If you can get it for $100 GO FOR IT. I don't have one myself (of you find another one let me know would ya?) But here's a link that can describe it pretty good. Pros and cons are talked about here. But seriously, if you find another one for that much, would you please let me know? Thanks

$100 thats cheap. What comes in the set? What pulleys? If you want the UDP for the crankshaft, then your going to have to have a pulley that is balanced, basically like the stock Harmonic Balancer. Our engines have to have it. If not, then it throws off the engine b/c it is taking all of the vibrations of the crankshaft. Buschur Racing has the Under Drive Pulley set with all the pulleys plus the lightend crankshaft pulley. That would be the best way to go if you have the money. $350. But its Buschur. Its worth it.

I've heard nothing but good things about Unorthodox underdrive pulleys from some of my 300zx buddies. They have been around for quite some time and have very good prices also. $100 is a steal for those! Get them!
