you're just starting with the wrong car. A CL-P and an Auto. Unless you're very handy and can do things yourself, just sell your car and wait for the right CL6 to pop up.
Also this is a thread about pullies, so don't de-rail.

Mine are holding up great. No problems at all. The only thing I'm mad about is they don't look as clean as they were when they were brand new anymore lmao.

I can't friggin wait....ralco woulda been 170 on ebay...bought from Josh at XLR8 performance for $215 shipped...Unorthodox produces them for him. They improved the design too and it's down to 1 pound even.
Should be pretty amazing.

I know many people on here will disagree or not respect this but if I hadn't of bought my pulleys used and for so cheap, I would've been highly disappointed in the "gains" I got from the UR underdrive crank/alternator pulleys. I felt VERY little, if not nothing, from this swap. I typically see reported/estimated gains of 10-20hp but I found myself closely analyzing the engine just to see anything at all.
I agree that in park and neutral that you most def see a snappy response. It's beautifully machined and appears to be precision balanced when revved high. In comparison, the UR pulley was significantly lighter. But never seen the performance gains....
Logically speaking, I understand that it primarily frees up additional horsepower by spinning engine accessories slower. it's an understandable concept. I get that! And in an unbiased analysis, the gains that were made (I know they were there by physics) would to me not be worth buying these pulley sets new. I bought mine used for $100 so this helped with my lack of results.

True, but the stock sized one discussed isn't going to underdrive the accessories...and the gains are from the weight being lighter so the engine uses less of it's oomph to spin it and more to move the car.
I agree...you likely won't feel the difference like you would with something like PCD's or jpipe...but it's there, that much, I'm certain of. And if it aids in making the car feel "lighter" and helps with some city mpg...then I'm all for it! Even at 200 bucks.

I had posted in so many threads about this I forgot to come back...
No, definitely not disappointed. I ended up spending the extra scratch to go with the newly designed and 1 pound UR pulley...
My impression, well worth the money...the car feels lighter upon acceleration, and there's less of a drag when downshifting or letting off the gas (if that makes sense). Call it placebo, but I do find myself enjoying chill city driving more now...
Also, between this and my high flow primaries...I've gotten no worse than 21MPG...when prior was getting 18ish when driving harshly.

Sorry to bring this thread back up again but I didnt see the point in making a new one. I see that horsepower freaks sells a Ralco lightened stock size pulley kit. I honestly just want the crank pulley but for their price I can get the alternator and power steering pulley as well. My question is will i have problems with the A/c and voltage at idle with this kit? Or I be better off getting the one off Ebay since im only really interested in the crank pulley? Below is the link.

The A/C performance will take a small hit, and the alternator will also take a small hit. Not too much of a problem, but I chose stock sized because I need my A/C in Arizona and Cali heat.

<- Underdrive crank pulley from UR since about 2003. II've never owned a stereo system in any of my cars so I have no experience in that department. But as for reliability, I've never had a problem once and have used this same pulley in my 3.0 engine before moving onto the one I have now.
As for dyno results, I can tell you it is minimal, BUT you do feel a difference throughout the rpms. The engine did rev a bit quicker which imo was noticeable.
Stock the 3.0 put down 150whp. With intake, headers, exhaust and pulleys I made an extra 13whp and about 12lbs torque (dynojet). After the tuning the VAFC2, I made an additional 12whp and 11lbs of torque with those mods on the dynojet. So respectfully you might see a gain of about 3whp throughout the power band with the pulley alone.

I would really like to get the one excelerate sells, but im tight on money especially around christmas time and I dont see the point in spending $220+ when I get one for ~$30 from Ebay.
the one Ebay is the Ralco brand correct?
On the Horsepowerfreaks site it states that they are stock diameter. I have emailed them to see if I can just purchase the crank pulley, all I saw was the set.
