Superlubricity - your technical threads are logical in their construction and thoughtful in their execution. Wish more would follow your lead - would be a worthwhile template for others to consider when documenting the efficacy of their modifications.
Glad to see this gave you solid results; look forward to reading about whatever you pursue next.

Great write up as usual. The power gain is really impressive throughout the power curve. Man I'm tempted to do this or the EC pulley next. I was hoping the install was a bit easier since I typically do them myself.

Hey Super, or shall I call your professorlubricity, quick question. Why did you guys have to heat up the pully to install?...can you describe a bit more.
Thanks.
Thanks.

You need to heat the pulley's hub so the metal expands. This is what allows it to fit over the crank shaft. Once it cools, it forms a snug pressure fit.

Simon, have they had their summers yet? Just wondering since this was posted in 3/10 and we are now entering summer. I would like to hear from others who had this done and live in the SW desert regions and how their ACs have performed.

Fuggedaboutit Sin...this is a nice mod but in the Southland...I shudder to think what would happen on those 116° days.

Their summer is now. I'm in the middle east right now and all is good and recent installs. But this is not the first summer that has passed with parts on cars here. Cars have had this installed since last summer as well.

Ok guys I’m going to ask a very important question, larger diameter pulley is reducing load
My Major concern is the long term effects of this pulley on the main seals and the low end due to a balance issues. Lets not forget the load on the ac and how hard the voltage regulator is working now.
What long term testing is done or are we doing the testing? And if its sooo good why are the big name guys not doing it. I don’t know but I’m passing on it. WOW very scary!!!!!..I like to hear some inputs on this..
On the Positive note, It looks very nice tho.

First, our damper is SMALLER, not larger than stock. It is also lighter than the stock damper. The stock unit uses an elastomer type dampening system just like it did on the 55 Kompressor. As I mentioned before, long term the rubber elastomer will degrade introducing harmonic distortion over time. Especially on a modified vehicle.
Our damper, which we have been using for about 8 years now uses an active technology system. We have had zero failures and I can say we have the most reliable "pulley" on the market. More reliable than pulleys made by "the big names" you imply.
Smaller damper will underdrive the accessories, but we don't underdrive them enough to cause short or long term side effects. Remember the manufacturer builds tolerances into almost all components. No different than how your transmission has more load on it each time you add more power.
The reduced weight of our damper also reduces the amount of rotational mass on the crank. That combined with its reduced size translates to a recapturing of energy that is otherwise lost to spinning components. This recaptured energy is sent to the rear wheels where it translates to more power to the rear wheels.
As far as why the "big names" aren't doing it. My emotional response is who cares. <pause> Ok, now that I'm over that, my actual response would be that having a "big name" does not imply you can put out high quality, reliable or even revolutionary products. If you really believe that, then you are fooling yourself. We may not have the big marketing or advertising dollars they do but we don't shortcut quality or reliability. Evosport leads, we don't follow. Perfect example: we design and manufacturer pulleys for the BMW M vehicles- the first to do so. We have been for many, many years. In fact, the #1 aftermarket mod in the world for the BMW M5 and M6 V10 is our Power Pulley. We have sold thousands of these. After realizing the success of these, several companies, including the famous Dinan itself (the same company who wrote a white paper condemning the use of aftermarket pulleys), suddenly released a pulley for the same vehicle. But I'm not upset. Imitation is the sincerest form of flattery right?
But consider the M113 55 Kompressor motor. I think everyone eventually released a pulley kit for that engine- most of whom just used the stock low quality elastomer setup as a starting point. The idea with the 63 is the same except it's a single step pulley and we're not overdriving a blower, so power gains are not as massive.
At the end of the day, we can throw dynos, customer feedback, specs, history, etc. to prove the point. All which support the product's claims. So you can either get it and enjoy it or sit back and watch. There are some people you can never make happy or content and that's fine. But we can just keep making great products!

So please correct me if I’m wrong, if we have a modified vehicle we should keep an eye out for degrading on the rubber due to heat and other factors to prevent this …. But yours does not use this rubber im think king your using the I thnink the name is "fluid material rubber like Instead" ? to reduce the harmonic distortion?
I still have questions about weight and other factors that would be too much to be discussed here, I guess I should call you if you don’t mind to answer some of my concerns….

Our pulley is not a fluid damper. They are good, but our active dampening is still superior.
