Steve-
Thank you for your interest in evosport!
We currently offer the most complete and powerful performance packages on the market for the 3.2L Kompressor motor found in the C32/SLK32/SRT-6. We have sold a number of these packages to SRT-6 owners, many of who are on the Crossfire board. I'm including a link below to the Power Package (includes our ODPS + suited software) we offer for the SLK32 that is also applicable to the SRT-6, with one exception: the windshield washer reservoir conversion is not applicable to the SRT-6.

The above kit includes a SOLID crank pulley. We also offer a kit with our new DAMPENED crank pulley. This kit as a power package is NOT listed on the website yet, but is available. It is about $500 more.
Here are a couple links to our ODPS (Overdrive Pulley System) pulley kit for the same car (w/o software). One with a solid crank and one with the dampened crank so you can get an idea of the difference:

Simon, I have a couple questions,
1 - What's up with the washer reservoir, what does it have to do with the package?
2 - Does the new evolution 1 Power Package include the chip and I get to keep my OEM chip?
3 - What is the differences between the solid & dampened pulley, what are the benefit's compared to each other?
4 - Why does the Over-Drive Pulley System (ODPS) w/ Solid Crank Pulley say dyno tested 13 hp gain & then claim 30 hp gain on the SLK32, and does this kit not require a ECU or chip upgrade?
5 - Why do your kits require what looks to be 6 pulleys and the RENNTech kit only requires 3?
Thank you, Steve
From how I interpreted the specs the whole set up of pulleys are both underdriven (for all the accessories) & overdriven (for the blower). How I read it is that the underdrive pulleys alone are worth the 13 horsepower, plus with the additional overdrive pulley the total increase in horsepower is around 30. I believe the Renntech kit is an overdrive kit specifically for the supercharger only which would explain why Evosports kit comes with more pulleys. I wonder now if Evosport had a better ECU setup how much more power could be extracted? I agree with SRT6_Roadster to stay away from the undampened pulley, especially for a street driven car where reliability is key.
