ok so heres the thing.

i have spoken with jerry from eurocharged.
i asked if he could develop a supercharger pulley for us 202'ers and he said he might be able to help.
he has built supercharger pulleys for C32's.

so he wants a pulley in order to have a look at it and see how it works.
is anybody close enough to him to be able to help out in this possible milestone for 202 tuning?
basically you need to get to him and give him a supercharger pulley for a while....i'm sure he's gonna give it back....lol

he is at : 6134 denton drive, dallas, texas, 75235

lemme know guys so i can arrange it.

ive seen them on ebay for sale. You can look there or a junkyard for one. most of us DD our 202s so removing the pulley would render the car inoperable.

ANYONE??????????

I've actually found a solution that another 230K owner pointed me too.

http://www.international-speed-parts.de/products/de/kompressor-kit/kompressorkit-fuer-mercedes-200k-oder-230k.html

These guys are german but I happen to travel to Europe a lot for imports anyways. I will be getting one for myself on the next trip. If anyone else wants one I can get more and I'd only charge $300 a piece for the trouble of going over and getting them. While I'm over there I'm also getting clear turn signals as well.

dokotela

05-25-2012, 03:50 PM

seems inexpensive enough but i would tread cautiously. first check whether its for m111 or m271.

that would be useless to me as i have the Kleemann pulley kit already. i want the smaller supercharger pulley

zmatt

05-26-2012, 01:53 PM

A lot of progress could be made with a smaller pulley on the sc end. The problem is, its a clutched type so it can't really get any smaller. You would have to convert it to constant drive and code out the clutch programming from the ecu.

dokotela

05-26-2012, 02:09 PM

aahh but not unless Jerry from Eurocharged can build us the smaller pulley(clutch type). he has said he would look into it only if i can get a oem pulley to him.

zmatt

05-26-2012, 03:06 PM

There is a limit to how small a clutched pulley can be. Ours is already very small. Are you sure he wasn't talking about the crank pulley?

Yujin

05-26-2012, 09:12 PM

I'll have the money waitn, and maybe another customer lined up as well. WE both have C230K's. Whats the predicted boost/hp/torque that will come out of this pulley? Any estimate on labor? My mechanic says its not hard to do, but def. not a DIY

zmatt

05-27-2012, 09:47 AM

They don't say how many psi but my guess is 2 so you will be at 8psi. They claim 35hp and 33 lbft of torque. With what I make now (215hp and 230 trq at the crank) plus a tune and this I will probably be making C36 numbers or close to it. As for an install you take off your belt, put the pulley over the crank pulley, tighten it down and put the included new belt on. That's great if you have another guy interested. The more tuned w202s on the road the better.

dokotela

05-28-2012, 11:25 AM

if jerry wants to have a look see i say we let him have a look see

zmatt

05-28-2012, 01:37 PM

Sure but I don't have a spare pulley to give them and I don't think anyone else does either.

Yujin

05-28-2012, 02:33 PM

Thats not exactly a 'spare' part people have.

Mike51809

05-28-2012, 08:04 PM

I heard that just one pulley can mess up your crank? Just a random question lol That's what's been keeping me from buying one

zmatt

05-28-2012, 11:04 PM

mess up your crank? The worst I can see happening with a slip on type like that is it gets loose and it stops spinning the supercharger and the alternator and just spins free. You will notice that immediately with power loss but there wouldn't be any real damage. You could either keep a spare stock length belt in the trunk in case and pop it off on the side of the road and go stock in an emergency, or you could re-tighten the pulley.

its good to buy and send to the person willing to make a custom larger pulley.
youll have some difficulty finding an aftermarket pulley that is a good size (like the Klemann one I used to have), I think that was the largest one produced.

SLAMMED_C

06-17-2012, 08:32 PM

no I don't remember. but all we need to do is ask dokotela, he bought the kit off of me. maybe he can do a quick measure of the pulley diameter.

Mike51809

06-18-2012, 10:06 AM

Hi Everyone,
I got here accidently while looking for info on any details for a turbo W202.
It's quite some time but here's what I've done so far with a friend of mine who works in a local machine shop:
http://mercedesdata.wordpress.com/
I'll gladly answer any questions.

Hi,

I just purchased a new 220mm outer pulley from Germany and looks very like the one you fitted, I should receive it within the next few days so I like to know a few things if you don't mind?

1/ I presume your car is a C200 Kompressor?

2/ What gain did you make with just the smaller 87mm Kompressor pulley?

3/ What gain did you make with the larger 220mm Crank pulley?

4/ What was the total gain with both pulleys?

4/ Was the engine mapped once or twice?

5/ What's the quality and fitment like on the outer 220mm Crank pulley, are you happy with it?

Thanks in advance.

John Jones Jr.

05-16-2013, 10:34 AM

So I'm talking with some German company that Zmatt is dealing with and he says he can actually ship to the States for me. But he's asking me if I need the 185mm or the 192mm? Which one do I need exactly?

I know it's almost a year later but this may help someone in the future. The standard crank pulley is 185mm on a C230K. Pulley itself is about 181mm and the lip/flange adds about 4mm.

KrumB

05-16-2013, 10:58 AM

hi J,
Yes it's a 2.0 kompressor, 192 hp @ the engine, stock.
I measured the car when I bought it with G-TechPRO and it showed 145 whp. Then after installing the engine pulley and remapping (I have done no more remaping) it showed 159 whp and the gain was more than noticable. After reworking the S/C pulley to 87mm it showed 174 whp and the gain was again more than noticable. Meanwhile I changed the MAF with a one out of BMW M5 5.0 because with the original one there was a drop at around 3000-3500 rpm. I also changed the fuel pressure regulator with a 4 bar one.
Now the pressure is 14.5 psi.
10 days ago I ported the supercharger but haven't measured it yet.
I am more than happy with what I've done as the car runs very smoothly and it's quite fast. And last but not least consumes less fuel when driven normally.

dokotela

05-17-2013, 03:02 AM

What was your final air duel ratio?

KrumB

05-17-2013, 04:15 AM

At 3500 rpm is around 12.9 and @ 6500 rpm around 11.0.

dokotela

05-17-2013, 08:07 AM

The e39 m5 air mass sensor gave similar values, except at high rpm the ratio was in the 12's

John Jones Jr.

05-17-2013, 11:36 AM

K-B, that's good to know. Thanks for the info. No doubt I'll have more questions soon as I'm a total new boy to these C230K's.

dokotela

05-17-2013, 01:01 PM

The mods seem complete, however the gain seems rather minimal to be honest. Maybe the engine needs to breathe....induction and exhaust manifold?

KrumB

05-17-2013, 01:16 PM

Well yes. But keep in mind that the data is not from a dyno but from a g-tech which is not taking into account the air resistance. All runs are made on 3-rd gear and the speed is quite high.
Some time soon I'll dyno it and post the data sheet so we'll see. :)

How are you going to address fueling?

vaspen

03-01-2016, 03:13 AM

Fuckers massive.. said no woman ever .... Lolol
And I don't know yet I was reading on that a little , some guys over in the Taiwan group use a manual fuel regulator. But I want to see what boost I'm at first and how it runs before I mod the s.c pulley and fuel system at most I should need a bigger fuel regulator
Only issue is I had the head off and was porting and polishing it also (see other post)

piko

03-01-2016, 04:04 AM

You want to add fueling only when needed. And thats only at open loop, otherwise you mess up the fuel trims. You add fuel above 7PSI to get an AFR 12 and you'll be flying!
For fueling I suggest this:

First clamp the MAF signal at 4.6V
then add fuel with this
https://splitsec.com/product/aic1-g2h-gauge-pressure-2-hi-z-additional-injector-controller/

using something like this:

I was already at 8-9 psi stock :) I'm going to have a tuner do all the necessary stuff for the maf as far as fuel I'd rather drop a bigger fpr and injectors and run a tad lean

It doesn't matter how much fuel you add by increasing the fuel pressure and adding bigger injectors, the ECU will adapt to the increased fuel in closed loop and bring the fuel back down to where it was before you changed the FPR and injectors. I've done it overy and over, good afr for e few miles then it goes back to above AFR 13.5.

Believe me I've tried it all.
If you want to unlock the full potential of the engine you need to get the AFR down to at least 12.5 or the ECU will be pulling ignition timing. I will run but you'll be down by at least 20HP.
There are only two ways of doing this:
-bigger injectors and ECU remaped for them (this would be optimal but not many can to this)
-auxilary fuel injectors controlled by a piggyback.

piko

03-01-2016, 05:10 AM

Sorry guys for the thread hijack but it's a relevant question.

Piko, what do you reckon. Will I be running too lean with 10psi @ max rev's? I don't have a AFR gauge installed but have clamped the MAF @ 4.7v.

The stock injectors don't provide enough fuel for much over stock boost. Didn't you have yours remaped?
Many people just run higher boost with stock fueling and the ECU takes care of knock by reducing ignition timing. It does a good job but you're loosing a lot of power that way.

vaspen

03-01-2016, 05:51 AM

I also have port polish. And a nice header/full exhaust on mine I already know I need tuned they will do it for 600

Thanks for the replay Piko. Yes, I had mine remapped. So, that may help?

Would it be beneficial to just change to larger injectors anyway (without an ECU remap to suit) and if so importantly is there suitable injectors that are a direct swap that won't cost a fortune? I think I know the answer but would like to hear your view.

piko

03-01-2016, 02:10 PM

John Jones Jr.

03-01-2016, 02:20 PM

By just changing the injectors and not remaping the ECU for them you will not add any fuel. A lot of injectors will fit (the most common high impedance bosch type EV1) but It will just be a waste of money if you don't have the ECU remaped for them!

Thanks for clarifying that. Hopefully my remap will aid fuelling/power. I must make a point of getting it on the rolling road again, the only downside it won't be same RR as previous.

vaspen

03-04-2016, 11:24 AM

my pulley is on and everything is back together now, for a 9 1/8th pulley I threw no check engine light
ported and polished it still no check engine light
supper happy customer ? yep totally me ... 1st is quite the launcher .. haha
I do have the flat spot just under 3grand something just kinda stutters but none the less..
I will get a afr wideband and boost gauge put in sometime this month and I will get it tuned
motor revs way faster only downside is the exhaust is so dammed loud going with a quieter setup soon

next I'm going to update the intercooler and piping

yours is a Manuel isn't it ... I'm gelly ... lol mine isn't that hard but I haven't trans break launched it yet (sitting just under t.c lock up point )
if I wana launch hard now I have to take traction control off haha

djjs

03-31-2016, 11:46 PM

Running 0.85 bar peak, 0.75 bar constant.
Definitely faster than stock but not very stable, sometimes it pulls pretty hard, sometimes it felt sluggish.
I am running on oversized pulley alone, with hard piping and open blow-off / cone filter intake.
Had a header on but it blew and cracked after few weeks.
5 speed do made me envy... I want to swap my 722.6 out for a clutch pedal too!!

Some Taiwanese guy was tempering with FPR and injector, don't know how it goes, I am going to try replacing mine with Sannyoung motor's M104 injectors, heard they are identical as C36's

vaspen

04-01-2016, 11:13 AM

Djjs we must be the same lol I'm feeling the same response from my car you are getting dose yours have a loud lifter noise? (Made this noise prior to port and polishing the head) thinking something bad in exhaust or drive shaft
I have a dynocomp header for a w203-230 kompressor
I don't make jack for power until late 3500+ lol its really time for a high stall converter for me
my next step of attack is tune- see what the injectors are at (if I need bigger or not) do the s.c pulley for even more booooossttt and a bigger intercooler
Maby lower gear set for more gnarly takeoffs lol

piko

06-30-2016, 12:49 PM

My C200k with a smaller 83mm charger pulley now, along with the 220mm crank pulley. I also fitted a bigger intercooler and made a 80mm charger intake pipe. Peak boost is 1.1bar (just before redline), but just above 0.9 through the rev range. The bigger intake raised boost by almost 0.2bar but the new intercooler lowered it by 0.1bar. The much cooler charge air more than makes up for the boost drop. IAT's are 30 degrees C lower and cool down ver quickly when off boost.

You eather use a piggy back to alter the signal or just solder a 4.6V diode between signal and ground.

This Frankenstein pipe mod gained almost 0.2bar by itself:

so this mod made boost and made the s.c louder I take it ?

I know I have to be at least at that point a ported and polished head really wakes these cars up, overdrive pulley @13psi ,
and a really nice header :) not fleabay 3084
3085
3086

3095

piko

07-04-2016, 11:32 PM

Yes it got a little louder. Mainly because of the open bypass.
Got the pipe on ebay.co.uk, it's 2mm thick. A friend welded and beat it to proper shape. He's good with metal shaping. It's all smothed inside.

I reckon it's at the 250HP mark. I'm making an even smaller charger pulley then it's on to th dyno.

djjs

07-17-2016, 01:11 PM

Beating a stock EVO put me speechless....
That's beyond C36 realm I reckon.

So by clamping the MAF you simply solder a 4.6v diode on the bridge of signal wire of the MAF and ground? I am not an electrician, not so clear on how to make out that part. Would be great if someone knows his stuff could be more specific? A picture or circuit diagram?

I am going to put my header back soon since it's been repaired. Transmission is lagging sometimes, maybe I will check the fluid level and see if it's there.
Right now fixing the car seems to be more important than making it go faster...
Geesh... I hate hot Summer, here in Taiwan you get humid air 35' Celsius or higher at any time of the day during July and August.... Could definitely feel the car runs abit sluggish due to hot intake air
