I like mine.....it so far hasn't shown to cause any problems...
I think some of these guys here have had it for a year or two.....mine has been on since last year
It doesn't gain hp....it frees up some of the hp you already have coming from the crank.

You could go thru probably several vendors,....try Stillen (Adam Hume ext.138 or Dean ext.182) and a bit of haggling (tactfully) may generate a good price. I'm not sure if you can go thru Unorthodox directly or not. Try AvalonRacing or Southwestautoworks.com as other sources.

What's the exact size of the new pulley ? you could probally get one off the shelf and get it bored and slotted accordingly, for probally 1/4 of the price get me specs and I'll try this, i have access to a workshop where i can do this.

seriously though, it might be better just to buy one. i think the balance and the strength of the pulley is pretty important... and it'd be pretty difficult to machine one to very high tolerance on those terms.

The UDP is made out of aircraft grade alumnium and is made on machines that make airplane parts (the name escapes me right now) therefore the tolerances are extremely close.

If you are simply .05" off on the spacing of your weight saving holes, you can completely throw the pulley out of balance therefore possibly destroying your crank and bearings. Don't forget that the pulley can be spinning up to 6500rpms.

I believe it would be a mistake to try and fabricate one of these homemade style. Mine is a Quality piece and I wouldn't want to take a chance on something like this. Imperections on an exhaust are not equal tp those imperfections we are talking about. When you see the Unorthodox piece you'll see what I mean.
