underdrive pullies

[Furious]

what brand should i go with? im leaning towards the UUC ones, but i know there are many others out there, im trying to find the best suited ones for my car

any ideas or feedback welcome

[drz]

I have heard that the ones made by Unorthodox racing are a little better than the UUC setup. Thay are also a little bit more expensive. I don't know if they have their own website; I believe they run an eBay store

if u get ur under pulkleys make sure and weld the oil pan nut...

[Tochenzo]

why? used:

[SpeedInfusion]

because there are stories, lots of em, when the nut fallls off, all ur oil pan oil leaks out, as soon as the light turns on ur engine is screwed....new engine needed at that point or lot of internal work...

Steve Dinan says no to power pulleys:

Not saying he's gospel or anything, but he is really smart.

That's a good article, however, isn't the "Harmonic Damper" located in the crankshaft pulley?....So by replacing a few accessory pulleys, how is this goin to affect the damping of the crank?...the Hamonic Damper's still there.

It does have me thinking tho. I'm not sure i wanna comprimise the life of my engine for a few extra HP.

Anyone got any more thoughts?

yeah i also wanna know aobut this whole thing with the crank pully some say they have compensated for harmonics, but i think im gonna steer clear of any sort of crank pully,

Rogue Engineering.... I love them. Many people say to stay away from the crank pully.. cause you might damage the harmonic dampner... or what ever its called... but I've seen many people change crank pullies with huge effects towards power....

i might just do a fan delete instead of changing the crank pully

How is the oil pan nut related to an underdrive pulley at all?

[Tochenzo]

that's what i was wondering too

[SpeedInfusion]

check bimmerforums...search for threads with crank pullies and oil pan nut..i dont know the details...ive just heard..

[Tochenzo]

well you don't have to mess with the crank pulley, this is only the water pump and power steering. the one with the alternator and crank are the ones that have been known to mess up
