Here is the dyno for the upsolute chip
The Renntech pully was at 200 lb/ft from 2500rpm to roughly 4500rpm. The horsepower was at 180. thats about 15 more horsepower, and not at 120mph, also if you havent noticed the 180 hp number that the upsolute chip made was a spike, which looked to be in a gear shift. Wait till Renntech comes out with their chip, then we can really get some serious hp out of the car. I would say around 200rwhp and 210 ft/lb. That will be nice

what the hell... it looks like the upsolute car was shifted during the run, twice. that is not the right way to perform a dyno pull.
the renntech pull looks good, I'm curious what kind of losses they are seeing though, at 15% thats 239lb-ft and 213hp... It wouldn't surprise me if the losses were greater than 15% though, 20% when you include those heavy-*** 18s would be more likely (its called inertia folks)... that would make 223hp and 249lb-ft.

I had my stock 6 speed on the dyno today and it puts out 167 HP at the rear wheel. The Renntech pulley doesn't impress with 185 (only an 18 HP improvement), not for the 2k they are asking. I think it needs a chip in combination with the pulley to break 200 HP which is my goal. I think between a pulley and a chip programmed to take advantage of it, 200 is doable.
The reason the Renntech dyno looks smooth is because it's a 6 speed on the dyno and it's kept in one gear the whole time and the Upsolute dyno run was on an automatic so you are seeing a 1/2/3 shift and the spikes during the shifts which don't count.

I wish mine started with 167 thats between 197-200 HP stock your lucky to be starting with so much. That is 4 HP more to the wheels than the upsolute car did chipped. Oh and the pulley kit is not $2000.00 it is $1499.00. Warrenty included

I don't have a dyno available to me yet, and probably won't be able to get one until the weekend (Kleemann is in CA at our shop right now, not at their offices). I'll do what I can. I do know that the numbers reported on all Kleemann products are actual gains.

BTW how does Kleemann feel about evosport making there own pulleys?

In a few months many will be making pulley kits for the C230. I'm trying to get all the specs over to ASP Racing so they can start making them. BTW, their Eaton M90 supercharger pullies sell for $75 at rpmpoutlet.com and come in an assortment of sizes. A reasonable price for a pulley. If Renntech charges $2,000 for a pulley I'ld hate to see what they charge for a spark plug. IMHO Renntech does not want to sell any and priced it accordingly. What's funny is that people see what Renntech is charging and think they can get big bucks for a pulley so everyone's excited and trying to cash in on it. The winner will likely be someone like ASP that has the reputation and price. Afterall I've never heard of Kleemann, Carlsson, Wetteraur or RennTech before this forum.

It is not a supercharger pulley. The kit is a crankshaft pulley and idler pully.
You obviuosly never read any major car magazines. Renntech was in Car and Driver in November 2001. An E60 4matic wagen. It was in Motor Trend with a CLK 60 with a 6 Speed last year too. Brabus was in European Car this Month. Renntech was in European Car in Dec. Carlsson in European Car this month. KLeeman in Dec Car and Driver....on and on.
The Forum can both be a great place for knowledge and well as a repository for misinformation. I'd encourage you to read the MAJOR car mags, that actualy test the cars performace claims. Car and Driver, Motor Trend, Road and Track all have the equipement to test the tuners claims and they do a great job of it.
BTW the pulley kit is not $2000

Search tips
Check your spelling. Are the words in your query spelled correctly?
Try using synonyms. Maybe the site you're looking for uses slightly different words, like "film" instead of "movie".
Make your search more general. For example, instead of using specific product names, try using the generic product category.
It's not just a simple pully and I'll bet you it will not be 75.00. Why would you spend 1500.0 on leather, and risk problems trying a genairic pulley set up for 75.00, with out any company support? No warrteny! I don't understand that way of thinking. The weight is important, the balence is important, the size is improtant, the action of the damping is improtant. I'm sure other companys did like Renntech did and made and tested many different one's and dyno tested then feild tested. I guess what you are saying is that it's ok to skip all that expence and copy one from Kleeman or Renntech or Brabus and have it made cheaper. You are right with out the expence of warrenty and R&D you could make a cheaper pulley.

maybe i am too hung up on brands, but i would rather have a renntech/brabus/carlsson/kleeman pully, so i have someone to call and complain to.
they tested the pully, if it fails shame on them.
if i buy a generic pully and it fails, well who do i ***** at???

I don't understand how you can compare a Rolex watch to a hunk of metal machined into a pulley. I like my Rolex but it's just overpriced jewelry and has nothing to do with getting a better watch as a Seiko would last as long. Heck I can get a few Seikos for what Rolex charges me every few years for a cleaning. And I've had several warranttee claims on my wife's Rolex with the face changing colors and not keeping time. If it was a car I would have done a lemon law deal on it. As for Sony, I would not pay a premium for Sony as I've had lots of faulty Sony products. It's all brand image and marketing. Some people fall for it and some like me are cynical and skeptical.
These days a CNC machine shop can make a simple pulley to within thousands of inch tolarance for very low costs. I can take a Renntech/Kleemann/Wetteraur pulley to several machine shops and they can CNC machine using the same alloy a perfect copy for next to nothing. I bet if your engine blew up Mr. Kleemann is not going to write you a check for a new motor. I'm sorry about the misinformation about the price of the RennTech pulley it's only $1,694 or about $1,500 more than it's worth. And yes it's a crankshaft and they have their reasons for going that way but that doesn't affect the price that much. Look at what Kleemann charges for a whole set of pullies and belt for a Beemer, $399. What's so special abou the MB pullies, could it be that they charge $899 because it's a bargain compared to $1,694 and not because it costs them more.
As for reading car magazines, yes I subscribe to several but I usually skip the articles on Callaway Vettes, Saleen Mustangs and Brubas, Lorinsen, RennTech MBs because I have no interest in them. To me they look ugly, like ricers for people that can't make their own but that's just my opinion.

Time to buy a TAG Heuer Buellwinkle do you realize that the crankshaft pulley is not one solid piece? It has a large damper (large rubber bushing) built into the harmonic balancer that is one reason the price is higher that a simple metal pulley.
The 15 HP gain was posted early based on a dyno of a non production pulley kit, Renntech is getting more out of the final production kits. The exhaust will only add a couple of HP the rest is realized from the pulley and settings.

Tag Heuer? Aren't they Rolex wannabees?
I know the MB crankshaft pulley has a rubber damper. The Kleemann pulley does not. Don't know about the others. I asked Kleemann 'bout that and their reason is that it's to reduce belt vibrations and it's effect is minimal. On the other hand they claim the Renntech kit is just a ring that clamps onto the pulley to make it larger. I though that was a clever idea for a K-Mart solution but they say it's bad. Is that true about the the Renntech kit? Also Kleeman puts an underdrive pulley on the alternator to compensate for the larger crankshaft pulley and the others don't. And Evosport wants to take that idea one step further and create an underdrive pulleys for the whole motor.
As for buying a lathe to make your own, that's a great idea. Can you make mine? Personally I would go to someone that really knew Eaton superchargers and had the CNC equipment to make really nice billet ones for cheap. That's why I went to ASP Racing. Hopefully they will make one for the little coupe.

Tag the other swiss watch no 500 a year tune up required
No the Renntech one is the complete crankshaft pulley including the damper. Sorry not a K-mart clamp on. It sounds like the one from Renntech is made as closer to the original specifications of Mercedes except for the size. That may account for the difference in pricing also.

Marketings job is to spread FUD (fear, uncertainty and doubt) about their competitors. It's good that we have some folks that have done it to straighten that out.
I though the other swiss watch was Swatch!

KLEEMANN Boost Kit
The KLEEMANN boost kit is a new crank pulley made from a solid 10 x 6 T6061 alloy billet. More than $75 worth of material by anyones standards. You get what you pay for- always. Rolex cost more for a reason, as should soundly engineered components for MBZ.
The Carlsson pulley system is a bolt on ring, not RennTech. If you are going to quote conversations we have, do everyone a favor and be accurate.

I think it's between Carlsson and Kleemann. Anyhoo, I don't see the ring in their kit, looks like a pair of pullies and some piping. Here's the pic from their website. Kleemann, are you sure it was Carlsson with the ring around the stock pulley?
I don't know what Carlsson charges because when I contacted their only authorized US importer on their website, Tire Rack, Jake says that they don't sell that because Carlson's engine mods are illegal in the U.S.. Of course that got me thinking, does anybody, including Kleemann have a CARB and EPA Certification for any of these pulley kits or ECU mods.
