Well, I went to Engine Logics to have my UR pulley installed, as they could not break the crank bolt loose. I will try another shop soon, then dyno the results. Sorry guys, I am dissappointed also, as I really wanted to see the results.

haha ^^^ word, I don't know how you can call your shop engine logic and not manage a crank pulley. Did they give you a reason? was it an accessibility issue or they just couldn't get it loose.

Many times the factory bolt gets siezed on there. There are a few "tricks" to crank it off, Im surprised they couldnt do it. This usually happends on older vehicles where the bolts been siezed on there for awhile.

i totally understand about how hard it is to take off OEM bolts....... my HFC took forever to install cause of those OEM bolts..... but this is different so... yea....

Nuts are nuts and bolts are bolts.
On the other hand, if you look at how nuts are matched with bolts at the factory, this might make more sense. If the nuts are installed while they're hot or if the heat of installation is considered...

If we assume that the diameter of the lighter pulley is the same as stock, I would think that the force required to turn the light pulley would be less than that required to turn the stock pulley, hence a gain in power.
Bet you can't really see that on a dyno chart.
On the other hand, if the lightened pulley diameter is different such that it's not turning the other pulleys at the same rate...
I seem to remember having to do that kind of problem in physics class. Of course, back in my day, we used physics version one. Maybe it's different now.
Any input from the mechanical engineering students out there?

I'll go with that. Show me the money.
I don't post much anymore because my car is done until the tires wear out. Then I'll do the suspension and maybe the wheels. I AM thinking about a cam kit when they're available from Stillen. Decent gains with the right cams and a (flame, flame) Hondata type ECU system. Flash is good, programmable is where it's at. No forced induction with this car, though; wouldn't be prudent.
Might need a better fuel pump and bigger injectors, though. 
Until then, I'll probably just chime in to pi$$ off certain people when they get stupid and try to violate the laws of physics.
Where's the dyno?
