What kind of gains has everyone recieved from pulleys? I need to replace the tensioner and thought that I may as well do all of them.

Adding a crank UDP will gain you between 2-5HP/TQ. And you will be able to rev quicker.

dont do it if you are running alot of ice, it will under-drive the alternator.

Define "ice" please. I want to say cold weather but not sure.

Could a normal auto shop do the crank Underdrive pulley for me? Or am I stuck having to do it on my own..?

Any shop can do it, it's very simple. Though when it comes to aftermarket parts, not every shop is willing to do it.

Should I get an adjusable one or just a regular one?

I did a UR crank (underdrive) with a aem alt (overdrive) and like the setup. easy too self install. I can give u the belt number also if you have a/c that was the only issue.

Reply of Shamun:
I recently purchased a UR U/D crank pulley. I am interested in rotational weight loss. Is the forementioned AEM Alternator pulley (O/D) any lighter than stock?
Since each pound of (rotating (or recip) weight loss equals 2.8 HP, how many HP can be expected from a Fidanza aluminum 8.5 pound flywheel? That is, how much does the stock flywheel weigh? LASTLY, I purchased the ZX3 head from FRPP and was wondering how much to mill so that I can get 11:1 compression. I plan to use my Crane Stage 2 cams.
THANKS!
