I'm familiar with UR press material/statement and the theories, but nothing beats hard data.

I dont see this question being asked previously or i'm blind...
JTso, how much hp or whp did this mod help you gain on the dyno? I'd like to see how many hp per dollar on this. Because I'm more inclined to do DC header upgrade on top of the already-installed CAI before these UR pulleys. If I understand correctly, it's always better to get the air flowing more smoothly from front to end first before stepping up another level. Correct me if I'm wrong.

do you happen to know the whp numbers before the UR pulleys?

So like Jtso said, the results vary.

I dropped my car off at a shop today to have these pulleys installed. They quoted me OVER $450 to do the job, w/ 4-6 hours shop time @ $110 / hour. I told them exactly where they could shove it.
I went ahead and orderd the crank pulley tool (since I have an AT). Man is that thing expensive for 1 wrench ($90 shipped). Anywho, this will definitly be the hardest DIY I will have ever attempted, so please look for my requests for help this weekend JTso![Smile](https://acurazine.com/forums/images/smilies/smile.gif)
With this in mind, is there any particularly tricky piece of this install? Other than the fact that it looks time consuming, it does seem doable with the right tools (and you of course provided a great list up front). The hardest part to me actually looks like removing the alternator. Any tips or thoughts on that part now that its 3 months stale in your mind?
Thanks as usual. -Reach
If anyone wants to come watch (you DC guys) and feel my pain you are more than welcome.

Where can you get the belt K070683? I live in Australia so things are not readily available. And apart from jackstands and a jack + a buddy, I have a complete set of socket tools (braker bar, ratchet, 6 point sockets, + a breaker bar extension). Do you think I am adequately equipped for the combat? Can I just tighten the bolts without using a torque wrench and just use the 90 degree reference that JTso pointed?

SiR Jtso: But is the Gates brand available worldwide? K070683 (69.09" or 1755MM), is the length standardized? Is tightening and removing the bolts can be done using ratchet and a breaker bar?

I wouldn't try to tighten the crank bolt all the way to 90 degrees as it's almost impossible to do. I would only use it as reference so you know how far you are from it. You should check your local auto part stores for the belt as it's a common part.
Is there some specific reason this can't be done with hand tools only? I was planning on tackling this job this weekend, but I only have hand tools.

Actually, I will be installing an intake manifold heatshield gasket soon (between intake manifold and injector base). This is in addition to the Hondata gasket.
