Im thinking of getting a Weistec S/C put on my SL 63. Anyone with experience? Any SL 63 owners do this mod? I am eager to talk to SL 63 owners with this mod, as it seems fairly straight forward and good for a 100 HP to the rear wheels.

Gene Gorman

Two fourm members in the CLK63 Black Series fourm have done this.

I know, I think its pretty bad ***. The only thing that has me worried is the MCT transmission. Can it handle the boost in power? The CLK63 BS has the old gearbox, which is bullet proof.

modoindustries

Do we have any members with the MCT trans and this?

modoindustries

BUMP.. I cant believe that Weistec claims they have sold many units to SL63 owners and not one of the owners is on thi site.

jacob502

who did they sell them to. Dont believe them. by the way, your MCT transmission handles more torque and more horsepower than the CLK black series old transmission. Therefore, you can stop worrying. Weistec is a joke. For a veachile that is already modded with a tune, headers, midpipes, intake and filters, the SC only gives about 40 RWHP. and thats a sad fact.

Do you see any dynocharts with a C63 making above 600 RWHP from a weistec supercharger?

let me help you......NO, HELL NO

I gotta agree with jacob502 on this one,
I was expecting alot more power from the Weistec supercharger, atleast high 600-low 700rwhp.
Maybe running high boost can accomplish this accompanied with race gas?

I dont know what you guys are complaining about, my CLK BS got a 130hp increase from a stock car. As if anyone could even use 6-700rwhp effectively anyway in daily driving which is what i use my cars for. Take a chill pill and calm down. 630hp is plenty enough to use in everyday driving for 99.99999% of people. If you are track hero and wnat fast and furious type numbers then get NOS or something. If you have headers etc their Stage1+ system Weistec gets you 672hp - in this seems plenty for $15k. Again thte power from mods doesnt always just get added on on top of the other. Some mods cannabalise the power gains already made by a cars existing mods if you know what i mean, ie 1 +1 doens always equal 2. So you cant say whell my headers gave me 50hp so therefore i just add the incremental hp from supercharger on top of that.

Modding these cars is not easy, their is plenty of low hanging fruit to be picked in getting a C63 in particular to over 500hp at the crank and even 550hp. However from my experience once you go past that figure the dollars needed for every extra hp goes up almost exponentially. This is particualrly true of the higher hp stock models like the SL63 and CLK BS which are already at over 500hp crank in stock form. It might take several times the dollars to add the last 50hp as it did to add the first 50hp via modding a stock car.

Check out the CLK63 Black Series forum. There are some good reviews.
I think Graham knows about performance. 1st at Daytona and 3rd at Indy. and he likes his.
This is what he had to say about it after he drove back from his 2nd place finish in his Indy car in Milwaukee.

Drives: CLK 63 Black Series


Just thought I'd give everyone my impressions. I got my car back this weekend in Milwaukee, and drove it around there for a while, then the 270 mile trek home. The car ran flawlessly. So much fun. The combination of the Evosport and Wesitec parts, the car sounds absolutely mean as hell, and is fast as can be. For a daily driver, I dont know what else you could do to have something better rounded and more fun.

On the journey home cruising about 80 I got 20.5 MPG average. Not terrible for 560 rwhp!!!!!!

Absolutely love the car and couldnt thank Steve enough. I think this is something all BS owners should do without any worries or regrets. They will love it!

Maverick1975

I took my supercharged BLack Series on a decent roadtrip soon after it got back in my hands and it drove like a dream. Phenomenal power on tap at all times. I agree with Rahal's comments wholeheartedly!

jacob502

You are one of the few that did the smartest move. You added your weistec to your stock BS. You are tight, it does give you over 100 HP over stock, but not when you have mods like LT headers, Midpipes ,intake, filters, power pulley. We have a C63 with full mods from MHP here in Qatar, The weistec SC only added 40 RWHP. now, is that worth $15000...certainly not

1- Headers, tune, intakes, ECU, Ported Heads, X pipe, filters---around $14000 and get you to about 630-640 HP, 725 NM tq

2- Weistec supercharger...626 HP, 745 NM $15000

3- Both of the above: around 670 HP 870 NM for around $30000


The weistec comes really in use if you start from stock form. Other than that, its not really worth it. (just like what you did Mavrick)

I still like #1

modoindustries

I emailed back and forth with Steve, he tried to arrange contact with a SL63 owner and a E63 owner but they both fell through. I dont think he is a liar, I just think there are not too many SL63 and E63 buyers that had this unit installed.

modoindustries

I would be perfectly happy with 550 to the wheels. More than that and it becomes a matter of traction and putting the power down. Im not trying to build a 1/4 mile car, but a wicked daily driver.

modoindustries

Thats exactly what I want to hear, but from a SL63 owner.

modoindustries

This is exactly where I'm, coming from. My car is bone stock, and I think this is the best bang for the buck. Now to find that elusive SL63 owner with the weistec S/C.

Hello fellow SL63 owner. Not trying to dissuade you, but do you really need it.
Like everything you want something for a while and then you gradually forget
it.Don't get me wrong I wouldn't say no to 600 bhp, especially about a year ago, it just takes a few races where you win to make you realize your already
driving a very quick car. Mine has been re mapped and I have K & N filters.
I don't care what others say my cars has 550 bhp rather than stock 525. I
can't remember the last time somebody left me behind, and if they have more
power lets see if he has the guts to use it. I love my car, it drives beautifully
long distance, it's fun, it makes lovely noises and gear changes, and is a convertible, what more could you want. I suppose when your sitting at home
you brain can be pleased by knowing it has 600 rather than 550, but in the light of day you forget it. Even with a supercharger there will always be something faster, you have a great car that 90% of men would give their
right arm for, enjoy it, my car gets looks all the time as well. Save your money
or maybe re map with some filters. What ever you do, you'll still have the best
SL MB has ever made.

modoindustries

At best our cars have 400 hp to the rear wheels. With this your looking at 550 to the rear wheels. More power is exactly what this car needs. I love the car, i'd love the car more with more power. Think of it as a perfect girl who is made even more perfect with a nice boob job.

You have hit my soft spot ***** But I don't like artificial ones, now
if I could swap the SL for a gorgeous girl with ***** like coat hangers
an natural , no contest.
I suppose the 63 is like the natural ones but maybe a tad small.
Still post the results if you have it done, how much is the cost?

modoindustries

The cost is about $14k installed, but I have no intention of being the SL63 test subject. I'll wait for confirmation from other pioneers first.

14000 no thanks.

Maverick1975

Longtube headers with an xpipe really wake this car up. I have had it done on my SL63 and the diffference is really remarkable is truly remakable. I got a 100Nm increase in torque between 2000-5000rpm. That is just phenomenal.

darmawaa

I've installed Weistec in my 2010 W212 E63, which use MCT. It can handle the power, no CEL, no clutch slipping,etc. The MCT in S63 PP can handle 900Nm.
I can definitely feel the power increase. In 50-80km/h driving, dry road during kick down the traction control lights on all the time, much more often than before SC install. I would say at least 30% more power than stock.

Maverick1975

Do you have before and after dyno tests for your car??

darmawaa

I'll be overseas until end of July. Will dyno after that. I've done my baseline dyno, so I can compare.

modoindustries

That would be fantastic. I would love to see some real world numbers.
