Wow, they actually came out with a product. I heard it was "supposed" to happen months ago, but thought it was just one of those rumor things.
The price is in the same range as others (I was expecting a lot more given the name) and the gains are similar. And there's the warranty (not a huge issue with this type of product, but if you're a worrier it probably gets you off the fence). |

Corrected
Hey Guys:
Mine will ship this month and be installed in a couple of weeks. I'm actually getting the first one produced, based on placing my order 2 months ago. This is the most aggressive pullley kit in the market, even though Dinan claims 11hp, versus others claiming 21hp. We all know that this is simple math. Unlike an ECU tune, where others claim 20-30hp gains and nobody really knows, this is purely mechanical, and a greater reduction %, will produce more HP, period. I'll post the results after install.

We should be doing a dyno before and after the install on CPIGUY's car. Well be sure to post up the results.

This is in an email form DINAN
"We are the most aggressive at 16.5% on one pulley and 19% on the second. " D |

Interesting that you'd say I'm posting mis-information. Out of curiousity, where did you get your info from?

You vaguely posted that the Dinan is the "most aggressive pullley kit in the market." I'm very tired of this type of subjective hyperbole here on m3post when it comes to performance mods, which doesn't really tell us anything. Your son's post regarding the actual reduction numbers is exactly the type of information that allows for a more objective evaluation and comparison with other products and I appreciate him posting it here. I got my info from calling Dinan many months back, but either I was misinformed or the specs have changed since then. In any event, I'm glad this finally made it to market. I feel like I've been waiting forever for it.

I was told it was going to be 16% a few months back by there head sales guy. And I assume Dinan is one the most aggressive one out since most are 15% or lower..

I have a question about the warranty that comes with this UD pulley? Does it just cover the pulley, or does it cover any negative side effects that may affect your engine from the pulley.

Dinan matches your new car warranty. If something breaks due to its modifications, they will cover it. This has been their 'unique' business strategy.

They list 2.5 hr labor so it will be another $250-300 on top, if you want the warranty. Not saying this is a bad thing, just musing. |

I recently had to replace Dinan muffler and Dinan knew that I didn't install from the authorized dealer. But they recommended to take in to local BMW/Dinan dealer for warranty process and they picked up wrong exhaust from local performance shop for me as well. It's kinda nice that they covered all parts/shipping/installation labor cost.
