Trust me, I have been waiting on these headers since late Oct of last year, when I first contacted Evosport.

Doesn't look like it will be out till Summer.

Could you please post a before and after dyno chart of the mach430 with the manifolds?

Nektopoli

I thought all Models 1995 and newer are covered for 8 years or 80,000 miles. Also do or when do cars in Europe have CC?

Does Evosport have anything up it's sleeve regarding intake or exhaust for the M111 C230 Sport Coupe?

If not, who does?

What would be the key enhancements required for upgrading the intake to the kompressor?

otoupalik

Nope, we don't - sorry!

these are the worst fukin aftermarket headers i've ever seen. you're selling a log-style manifold as a performance header? you should be ashamed of yourself for selling such a peice of crap to the public.

Vadim @ evosport

Another expert. If you had presence on the board (first post on 3.6.3), used normal language (f*****g), or even bothered to read all of the posts under this topic - then you may have deserved a response.

@ brabus benz

Instead of using strong language why dont you come up with some strong numbers ! Give us a detailed report of YOUR findings and present them for the public. I am sure many potential customers are looking at this board !
Make some strong arguments for your case and give Evosport a hard time.

But if you are gonna be shouting and screaming thin air then don't even bother replying.

Yes, I'm still patienly waiting for the final product and numbers.

I don't have 20k bucks to spend on a supercharger, so bolt ons are my best choice.

brabus benz

i did read all the posts, but i still wanted to give my opinion on this product. i'm sorry about the foul language but it's pretty hard not to cuss when you see such a ****ty product.

brabus benz

this is a product that's being sold so that people can just say that they have aftermarket headers. the power potential is minimal at best. the 90deg. bends where the primaries meet the secondaries are going to kill a lot of power. that's going to reduce both total exhaust flow and velocity. in addition it's going to cause tons of exhaust reversion back into the combustion chamber, diluting the intake charge w/ spent gases and adding heat to the intake charge.

maybe they don't have the underhood space to get the proper pressure wave tuning, which would necessitate something around 30" primaries, but they still could have designed it for freer flow. the fact remains that these is the most poorly designed aftermarket headers i have ever seen. i understand that they have to work around certain emmissions requirements, but if this is really the best they can come up w/ then they should of never bothered to make them. stock is just as good.

don't be sorry... just make us something!

I know there are supersprint headers and kleemann headers. Evosport sells the supersprints correct? Should I ask about observed gains here or start a new thread?

nukblazi

So if people have the money and they want to say that, what's the difference to you?

There were many re-enforcing comments made throughout this entire thread questioning the headers, and supporting the headers. Why don't you quote a specific comment/ question/ response and intelligently present your follow-up or original question, in a clear, concise, professional manner?

No one doubts the potential of you providing insight, your methods just leave something to be desired.

Vadim @ evosport

Now, this is a lot better. Using foul words only makes you look immature. Now if you want to share your technical background that would make your post look even better. Things like you having access to flowbenches, dynos, fabrication facilities. Things like you having made and designed headers, installed them on different cars.

Now back to design. I do not think you read the posts. There is no room to do anything else, if one wants to get headers CARB approved. As far as not making power, so far we are getting 14HP on a Kleemann S/C Car and 9HP on a normally aspirated CLK430. Factory manifolds are that bad.

The reason I have not posted dyno graphs, is that production pieces will have CNC machined flanges that should make even more power. Once I get them tested, I will post dyno graphs.

Header Flange Post

Brandon @ Kleemann

I dont want any confusion here so let me clarify: the M111 headers I posted pictures of earlier in the month were SuperSprint headers- not KLEEMANN headers. We have no plans to make any such product. The price point of the SS units is very good- we could never match it.

I have not installed the headers on the C230 K Coupe yet, I am waiting to complete the SC conversion fisrt so I dont sckew any results.

nukblazi

Whoops. Sorry for the misleading post. Thank you for the clairification. I thought you had said that there "were" kleemann headers in a phone conversation back in Nov. Sorry again.

I don't want to get off topic and I forget if I asked you already or not, are you doing anything with the intake?

brabus benz

hmmn, those numbers are pretty interesting, would assume that the s/c car would have a much larger hp gain than that, considering the n/a car made 9hp. forced induction motors are usually so much more responsive to a reduction in backpressure than n/a cars. a 5hp difference is tiny, and percentage-wise, that difference is actually even smaller (the s/c car has more hp to begin with). a bolt-on that results in a 14hp increase on a s/c car should come out to about only 4-5hp on a n/a car, if that even. maybe you just need a little more tuning on you s/c test car, i'm sure you can pull out a few more hp.

Vadim @ evosport

My guess, at this time, on why SC car is not higher has to do with TQ limiting in software. We will be addressing this issue with Powerchips shortly.

benzmac

As far as I know and can tell, the only cars with active torque limitation are the factory Kompressors.

I don't think you are running into torque limiters on the CLK 430.

Denlasoul

Do you think these headers will benefit a C43?

Lucas

ME 2,8 1 - 2 years back on NASP engines have torque limitations, it's calculating the torque over the air mass sensor.
Useing supercharger will 100% sure hit the torque limits, so reprogramming the ECU will benefit these cars, first tests show
approx. + 30 HP on a W 209 CLK 500.

Shine

Lucas
Are u telling the 30+ hp gain if I reprogram my ecu ?
How ?

Lucas

Shine

Yes, it's exactly what I am saying, give it a few weeks more so we have testes on more cars, then you can send the ECU to KLEEMANN DK or KLEEMANN USA, then we will fix it.

Shine

Lucas
Do all new V8K suffer this issue after a few run-in, then the claimed torque has been limited all the time till now ?

What happen if reprogram the ecu as you said
(1) Back to the Kleemann claims 506 hp/675 nm ?
(2) Extra gain -> 530 hp ?

Lucas

Shine

All V8 and V6 as well, all cars with ME 2,8 or ME 2,8.1 is under survaliance at the moment.

1: What do you mean by back to claimed power ????

You beeing on Taiwan, is at least 50 HP less that Western Europe, due to ECU settings, fuel quality and hot clima most of the year, but all cars suffer from that, not only yours.

2: There will be an increase, first tests show a significant extra power and torque, so if you are just as fast as the SL 55 you have wrote of before, you will eat it alive after KLEEMANN ECU programming.
