I think it's worth it.

It all adds up in power at the end.

Don't know what Mikey's talking about. The pulley is completely independent and reduces the power to the other belt driven devices. Ie. water pump, power steering, alternator, etc. By reducing the power lost to these devices, you get a little more of the engines power going to the wheels. I've put mine on, taken it off, put it on and taken it off again. I can tell you honestly that, on the positive side, you feel a slight difference in pull. Wheels slip just a little easier. Big difference? Not at all. Don't expect much from 8 HP over your 414. It feels a little more rev-happy. Climbing the RPMs just a hair quicker. On the negative side, the steering gets stiff at low RPMs like when turning up a driveway or in to your garage. Not too bad though. It feels like you pushed the M button. To finish, here's one nobody has ever mentioned - to my knowledge - but the car is much smoother when cold. The bucking effect with a cold engine gets much less, or better. Not gone entirely, but much better. After that, I'd suggest getting one. It's reversable so at worst you lose your $380 bucks.

Pulley is separate from other mods. A tune won't help.

I put in the RE pulley before I got a tune and it made a huge difference IMO. You're getting 8-10whp/wtq across the board. The power was only slightly noticeable over 5k but under 5k it's really noticeable. When flooring it in 5th at 2k rpm the car picked up much quicker.

I really felt a difference when I got the Rouge pulley, the numbers won't lie, and YOU will feel it, great mod so far

I had EAS install my RE power pulleys. Excellent guys to work with by the way! I noticed alittle more low end pick up in 2-3! To me every mod that adds HP felt or not will add up to more as you go! Every little bit adds up!

It is heavier. There is less power available to the other sub systems. From my understanding, it is only slightly.

There is a slight reduction in steering boost but you can still slide into a parking spot with one finger

You're referencing an article that was written almost 10 years ago. Word on the street is that Dinan will be offering their own UDP soon for the S65.

Otherwise, the RE pulleys have been a very good 1st upgrade.

You can't go wrong with the RE brand, here's a quick DIY to give you an overview of the install process:

What I am saying is to get the full effect you really need to do other mods as well as I have found out , yes the pulleys are good on there own but add other components and they all work to create a much better upgrade package

thats my opinion any ways

We have a link to the install in my previous post, this is about a 90 minute job.

"Word is on the street?" As if they were working on some secret long-term project? If Dinan wanted to manufacture UDP's he could do it in an afternoon. And regardless of when he published the article originally, his sales reps still reference his disdain for UDP's. Sorry Bro, didn't mean to threaten your third quarter revenue.
