They used a base line dyno on the car assumeing that
the base line was the facory rated HP and Torque, then added the diffrence to the facory rated numbers so there was no need to estmate the parasitic loss of the drive train. I don't have the graphs but i will see if they will send me one.

If we ordered the pulley kit where would we be able to have it instaled and about how much would that cost? Thanks for all the information.

renncpe

It is an easy install two hours labor. If you are handy you could do it your self. Having it done at the Dealer could be a problem depending on the dealership some are cool and would never give you a moment’s grief about warranty issues.

Otherwise I would suggest a private Mercedes shop or a local speed shop. It’s straight a forward bolt on install.

if you work on a groupbuy i'm sure many people will be interested

Hey Randy do you know what is the Boost Level is the Pulley Kit and Pulley Diameter? some of the kits bring to boost between 10psi to 14psi

vadim

Randy--
With the pulley kit installed, I assume the ECU wouldn't produce any codes that would indicate that the engine has been tampered with? Is this upgrade transparent enough so not to affect the warranty?

Thanks.

renncpe

You are correct the pulley kit does not cause any error codes in the computer. The kit is transparent to that degree; with out measuring the pulley and knowing what it’s supposed to be it would not be obvious.

Randy

vadim

...So it would be safe to assume that this modification is not going to ring any bells with MB techs (and result in a possible warranty denial), should the car need dealer service, right?

Thanks.

RIght !

If you have the C-7 package you already have a short throw shifter If you do not it’s pretty pricy to install it the part runs $510 and 2hrs labor to install. I have not cross referenced it but I think it’s out of the SLK.

I changed mine I did not get the C-7 package. That was a mistake would get now if I had know all the differences.

You can also get the color matched door handles like in the C-7 package. They cost about $63 a side are a must if you have the grey ones.

The U.S. C7 Wheel Package includes a short-throw shifter? Are you sure? It is not listed anywhere and when I test drove them, I didn't notice any difference except the smaller plastic piece (more leather) on the C7 shifter.

Can someone else confirm this?

Rick

Well, when I talked to Bob Brady at Renntech, he said the same thing. So, there's two sources.

But, like you, I didn't remember any difference in the throws. But, I didn't do them one right after the other. That's another reason for why we would need C230 meets in the spring, when things warm back up!

C230K

meet in the spring.....think we can meet here in Florida now. how about early Feb. for the 24 hours race?????????

renncpe

I plan on being at the 24 hour we will have to meet up there for sure.. Hurley Haywood is with our Porshce Dealership I'm not sure if he will be raceing this year or not. If he is I will have to have you meet him.

Randy

C230K

Rick, care to join us at the 24 hour, hope you car get's here in time. Well that would make three to go..... that's a start..

It appears that Wetterauer has a chip that would increase a peak engine HP from 193 HP to 230 HP and peak engine torque from 206 ft/lbs to 236 ft/lbs for $1,295. These are pretty impressive numbers.

Find more at Wetterauer's site for the US at http://www.chip-tuning.com. If anyone gets it, I hope that he/she will let us know.

gab

I checked the Renntech website and their kit for the SLK pulley only can upgrade the engine power to 205hp 220lb/ft so whats the difference with the new kit that offers 225hp 240lb/ft ?

Lynn

That is a pulley kit not a chip.

sk-mia

Yup, I know, I got caught in the web site name chip-tuning, and they have been known for making chips for Audi/VW, which have turbo engines that can be easily chipped. I guess that supercharger has to be done mechanically, that is, with a pulley and all that stuff. But, anyway, it seems to me that they are selling a pretty much the same thing as Renntech, except for $400 less. Would it be any disadvantage taking the Wet instead of a Renntech?

Lynn

I don't know the relative merits of the various turners' pulley kits. Brabus, Dyno-spot and Kleemann make them also. Most claim 230 hp and 250 lb-ft torque. That's a 25% increase in torque and the torque curve stays as flat over the same rev range as stock.

Upsolute Power is claiming similar results with a $325 chip.

vadim

...but it's listed on their website under "Chips For Mercedes" and pulley isn't mentioned anywhere... Are you sure it's a pulley kit?

renncpe

The 2002 230k fuel injection system is different the 2001 SLK 230. The ECU is also different it is now a sealed box before there were flexible tabs that could be bent to allow removal of the cover. The new one has a heavy metal tab that can’t be bent it will require cutting. The changes a chip will make to the system won’t be picked up by the service centers computer but physical changes to the box will be apparent.

I would recommend that you check the chip modifiers warranty; does it cover the chip mod or the whole ECU? Pulley Kits are another item; it’s not a race to put in the largest pulley but the one that produces the best streetable performance there is a fine line between power out vs power consumption of the supercharger.

There are only a few tuners that develop there own pulley kits and tune there chips. The others are just reselling a generic product. I would not let $300 dollars make up my mind between the best and the lest expensive.

Randy

Lynn

Yes. The price is the tip-off. It is much more expensive than the chips and inline with what others are charging for pulley kits.

vadim

I'm puzzled.... Here's what it says under CLK230K:

Tuning type: Hardware Upgrade;
"The kit includes a pulley that maintains the magnetic clutch, a drive belt, fuel pressure regulator
and special air intake pipe for the increased air volume"

However, under C230K and CLK200K :
Tuning type: Alpha (i.e. chip only!)

The "tuned" power and torque are the same in all 3 cases, so are the prices...

So, they must have updated only the CLK230 page and left the other two in "generic" form (copied and pasted from a template).

Thanks, Lynn!

I’m bummed my HID kit did not come in today as expected. Now I will have to wait until Saturday to get them installed if they come in tomorrow. My car should be complete by the end of February. Parts for the C230 are still hard to come by but I expect that by spring we should have a lot more available. I have already lowered the car but I found a full set up with matched springs, shocks, and sway bars. That is due in two weeks. That should finish up the suspension. I don’t believe that is a legitimate chip out there yet most of what I see look like chips for C230K sedan not the new Coupe. I will wait a little longer for that.

BTW a RSX might take me in a sprint like a 1/8 mile but that’s about it.
