Unorthodox Racing pulley

Is it worth the money to invest in one of these? If so where's the best place to get them, there's alot of sources and everyone has different opinions.

i bought one but dont really notice any sunstanial gains to warrant buying it. i just bought it cause im after every possible hp i can get plus it wasnt too very expensive. it does get your rev's up alot quicker but thats pretty much all i noticed. i know i gained some hp, but it was too small to notice. prolly somewhere around 5-10 hp. you could probably pick one up from our sponser, "sportcompactonly."

i also noticed better mid-range response.

with the new pulley does it funk up your ac/heat ? and can i put on them my self

[nismo1219]

i didnt notice it really "funking up" the ac/heat, but i DID notice that it doesnt blow quite as hard when idling, but picks back up when i press the accel. i had mine installed since i dont have the tools needed. ive seen how-to's (DIY) somewhere before, but i cant find it now. if i find it ill post it up for ya!

There are two types of pulleys. Underdrive and lightened. A underdrive pully is actually smaller and lighter than the factory pulley which will free up hp but will have the negative effect of lowering the rotations of the alternator and other accessories. A lightened flywheel is the same size as the factory in circumference yet made of aluminum instead of steel (Tho probably not quite as light as the UDP) and does not lower the rotation of accessories.
