I found MANY MANY MANY things about 5th gens with the pulleys installed but none 4th gens
anyways, i have a f22b (same as h23) and was wondering what the gains were like on the h23. how much better is the throttle response, idle, acceleration, and do the lights dim any at idle? why does it only come with a PS pulley and alternator, and NOT an A/C pulley? can you subsitute one of the pulleys for the A/C one?
Since apparently the search button is broken or something:
lights dim a bit at idle
gain some noticable torque from idle to about 4500
dynos have shown about 4 HP/4 ft lb to the wheels across the whole powerband.

When you replace the pulley on the alternator, it spins slower and produces less power
Is that why there are power gains? I don't understand y if the alternator pulley goes slower there would be more hp. Also, should u stay away from aftermarket pulleys if u have a system running about 2200 watts... lol

The pullies are larger in diameter than the stock ones.
Think of it like this: say you're trying to break torque on your lug nuts. Try it with a 6 inch long driver, and a 16 inch long driver. The longer handle will obviously make it much easier to turn the lug nut, right? Same theory with larger diameter pullies, only obviously not so dramatic.

You know how much sound 2200watts rms would produce? Lets just say you would have to be a decent distance away from the car if didnt want your ears to bleed.
I don't see how you do not understand the power gains. The alternator takes force to turn. This is because it converts mechanical energy into electrical energy to charge the battery. Since it takes a force to spin it it draws power from the engine. If you make i spin slower it draws less power. Also the aftermarket pullies are lighter so they take less force to spin which in turn is more power that goes to your wheels. So as far as the actual engine goes, it does not produce any more power but more of the power it makes goes to moving your car.
^^Listen to him. Just remember though, in a nutshell, lighter pullies that have a larger diameter put less frictional drag on the engine itself, which inturn allows more power to go to the wheels.

How do you get these figures? Going of all the rated values of your components is way off. Things like amps usually list their power in some sort of peak power they can deliver. This also depends on how long it can deliver this peak power. Say two amps that push 200 watts rms, one claims 450watts peak and another claims only 400watts when they actual both deliver the same amount of power. I don't want to bother to look up the figures but it does not take that much power to produce very loud sounds.
