The only pulley they sell is for the crank. The dual groove is being shipped now, but single has been out for a while. Futurersxswap has the single groove (no PS, but keeps A/C).
suppose this one is better but the unorthodox is good too
because you can choose how many pulley u want..or the whole set
but i am just getting the crank pulley so i assume this one is better

There is only one crank pulley. And guess what--the unorthodox pulley is not harmonically balanced. This means expensive engine repairs down the road. The DH-pulley is NO KEY WAY, meaning it presses on with no space to vibrate. Very safe and best gains.

I read the other forum and said that the DH dual groove crank pulley weight 1 pound. On Unorthodox website, they said that the pulley weighted 2 pounds.
and from Unorthodox website, they said, "Our crank pulleys are CNC-machined from lightweight 6061-T6 aluminum billet. Premium U.S. made 6061-T6 aluminum billet ensures the consistency of the material's strength and balance . Tolerances are held to within .001", and numerous machining steps are used to ensure the lightest possible design. In addition to fit, finish is just as important and each piece is representative of this. Every pulley is inspected multiple times from machining to anodizing to stocking and finally at shipping time. If at any point a pulley does not pass inspection it is pulled from production."
my question is...if Unorthodox pulley is not balanced, how come they still sell it on the market?
Also, how different compare to DH and Unorthodox pulley?
And who confirmed that DH pulley is perfectly balanced? Anyone actually did some test on D17? I know one guy just got the DH pulley.
Just some questions, don't wanna get flamed.

The DH-pulley presses on directly against the crankshaft (no key way). The UR pulley is different and WILL vibrate. A member on here reported having a very expensive engine problem occur from the pulley (from not being harmonically balanced). This happened about 6 months after he installed it. Needless to say he was pissed about it.
And DH-racing is a VERY well known company to date. They made the fastest all-motor honda in the world. So I think that means they make a better product. I would never get the UR pulley knowing what I know.
The DH pulley has nothing to prove. It presses against the crankshaft and there is no chance for it to vibrate. In that respect, it's even better than stock. The weight and shape is where most of the power comes from.

I've had NO problem with my Unorthodox set-up and i've had it for WELL OVER a year... I've beaten the crap out of that motor and it comes back for more everytime! I doubt anybody else's D17 takes as much a beating. And I have had no problem with my UN-Harmonically balanced pulley kit??? I stand by Unorthodox all the way. Who is DH racing btw? I've never heard of them??? (Maybe i've been living in a cave or something...
) Did they do Ericks car?

DH-racing got started in 1994 and has made the fastest all-motor B16A in the world. They are well known for engine work and N/A parts. And I'm only telling what I've heard about the UR pulley from other members. I haven't had any experience with it. But that's cool if yours lasted all this time.
