Zasker's UR SS Pulley Dyno

Zasker, still anxiously awaiting voltage readings, and english translations of how you believe the change has effected the car long-term .
I volunteer to take readings from my car, if you can provide good instructions on how you did yours to me, by PM would be best I guess.
I have a good multimeter and generally good EE skills, just don't know quite what I'd be looking for here.

Yes, baseline is with Header,Ct and intake. sorry about readings, we had a dust storm last night so I did not want to open my hood and risk it smamming on my head. Will try to do this tomorrow.

Voltage Readings
Ok,
Today I finaly had time to get some voltage readings. Although they are a bit under 14v with everyting on the drop is fairly small thus I do not see it being an issue.
Radio,AC,Heated Seats
Headlights, doom light:
Off On:
Idle: 13.71 13.3
1k: 14.17 13.8
2k: 14. 18 14..5
3k: 14. 19 14..5
I have also had some more time behind the wheel and the gains are still impressing me. 4th gear passes are now much easyer to accomplish and the car is much smoother when you mosh it from 1-5th.

So that slight drop in voltage wont hurt us people with stereos in their cars??? I remember seeing your car SToke at the meet and you sure did have a lot of gadgets in there...I ask cuz I had an Accord Coupe running these pulleys and it was amazing but I had no system...I hear of some stories though where the care completely dies...

Remember the drop is minor and realy only a factor at Idle. I supposed if you sat long enough at Idle. (few hours) you could kill your battery, but that is not something I am willing to test.

Its about average, here is comptech's own dyno of all three:

Remember, I dont have Exhaust as it does not provide much of a gain, mostly just looks, sound, braging rights.

tempting tempting...
i heard that if ur car spins out, on snow or wet road it could damange the engine?! i mean it makes sense cuz smaller diamater which means it spins faster. but i live in a snowy state is that something i have to worry about with the pullys changed?!
info info plz!! thx

If your car spins out your gonna have more than engine damage. But if you are refering to spinning the tires as if you had mashed the throttle on a wet road. You should be fine. All those accessories spin at over 10k rpm's as it is.

I really want to get the supercharger but i don't know if i can drop all that money on it... if not, i'm highly interested in this mod.
How difficult is it to get this thing installed.. i won't be doing it myself but would I have to be searching forever to found a shop in NJ that knows how to install this thing?

I think I'm just gonna watch what happens first before I decide to jump on this mod. I just don't like the idea of swapping out the crank pulley, and seeing as how that provides the most power I don't know if it would be worth just changing the others.

Other than the question of harmonic crank damping, which it sounds like the crank pulley does not do, what are the mechanical risks of a smaller and lighter crank (and accessory) pulleys? The accessories turn slightly slower, I understand, and that has some effect on voltage, a/c, etc. Those sound manageable, esp. with the stock stereo.
So, what is the mechanical risk from a light, small pulley set?

Link to Myths of crank pulleys n dampers
Been through several honda/acura boards and many people have used the SS and SSc pulleys with no problems whatsoever, some with over 2 years of use.
So they are pretty safe to use....
