which is better in the pulley department? and which is known to make better horsepower gains? ....the AEM pulley kit or the unorthodox set (all types)?

unorthodox makes more power b/c they replace the stock crankshaft pulley with a lighter one. this is where most of the difference is to be had. AEM's kit doesn't have the crankshaft pulley and only replaces the other pulleys.

I've had an unorthodox crankshaft pulley for about a year and it definitely pulls better. Mind you, it's NOT worth $200, but i got mine on sale for $95. There's alot of bad noise running around about 'harmonic dampeners' and how it's bad to do this to an engine because of crankshaft vibrations, oil pump failure, yakity-yak,,, but after almost 20K miles, i haven't noticed a damn thing. This is the supposed reason why AEM didn't do the crankshaft pulley.

I've talked to some people over the past year on alot of different boards and events and they pretty much all agree that YES harmonic dampeners are very important in larger displacement/ high hp/high torque cars(like mustangs, camaros, vettes, etc...) where the high torque and rotational mass of the crank is pretty big and pronounced. However in a smaller, less hp/torque, engine the effect isn't too dangerous (if it was my engine would have been torn to hell a LONG time ago b/c i tend to be a little rough on it ... my gas pedal has two positions: up or floored :) )

btw, if you've got the mack-daddy brick-busting stereo hooked up do NOT screw around with your alternator pulley unless you've got jumper cables and a very patient friend b/c your high powered stereo will suck your alternator's power drier than an L.A. porn star and it will not be able to run fast enough on a bigger pulley to keep the tunes moving.

So if I were to spray or boost an H22, would I have to worry about my harmonic dampeners?

Question for you, have you ever taken apart your engine after putting on the Crank pulley? if not then you can't really make the claim that it doesn't damage your engine. Think about it, if it is not important and will take away HP, why would the manufacture bother with it? The answer is simple, because they have to warranty the engine and HP gain VS the wear that comes with it is not worth it. Read the link below, the reviewer had the same view as you, thats is until he took apart the engine to examine it.
