I will buy them when they become a set. How bout AC Compressor pully? If so you have a 100% buy from me.
Could you shed more light, what "issue" are you refering to?
Edit, I want the underdrive set: http://mrzperformance.vstore.ca/prod...roducts_id/144
What size belt do you recomend with them?

The stock pulley's are harmonically balanced. The rotation of the crankshaft creates vibrations and if the aftermarket pulley isnt balanced the same, then there will be added stress on the engine causing problems later on.

How much of a difference would there be between in power would there be between the stock sized one and the underdrive one? Also how much would the underdrive one affect electrical stuff like lights and stereo and stuff? And finally does the underdrive pulley come with a smaller belt or do you have to get that seperately? No matter what i will be ordering one of these soon just gotta figure out which one.

I would want to do both the crank and Alt at the same time I don't really want to take it apart twice.
Tell us when the ALT's are ready will ya

I still want to know if it affects the electrical components. stereo, lights. etc. Im not putting a sound system in my car, so i wont have to worry about that.
Let us know, do a voltage test, before and after. and let us know if a new belt is needed.

If you choose the UDP version:
- If you car is stock on the electrical side or have a small sound system installed, there will be no problems with the UDP
- If you have big sound system or other things that takes a lot of power you might experience a power drop...
How much of a difference would there be between in power would there be between the stock sized one and the underdrive one? Dyno on the way Also how much would the underdrive one affect electrical stuff like lights and stereo and stuff? check previous post And finally does the underdrive pulley come with a smaller belt or do you have to get that seperately? Can be sold with or without the belt No matter what i will be ordering one of these soon just gotta figure out which one.
