I posted the other day that I got headers up on my C32. I thought I would post pix of them. So, without further ado, here they are:

looks sweeeeeet.... cant wait to see you break into mid to low 12s... go to the track and get us some bad *** times man!!! I need headers myself.. i think im waiting for Hotshot to come out with their SRT6/Crossfire headers!!!

psk145

are they equal length tubes? I thought their headers were made such that the tubes were the same length. When I saw the form or mock up thing at JP performance (who I thought made the headers for evosport), they were all the same length.

here's what Im talking about:

your headers look awesome though!! Do they have the ceramic coating?

dose this C32 header fit W208 CLK 320 ? BTW i had Supersprint header for 320 engine they were short close to 1" they dosent fit my car.

TC32AMG

Those are not equal length tubes, I was thinking the same as you and was looking at the same pictures at JP performance. I am contemplating whether to get the Shortys from supersprint or what I thought the equal length haeders from JP for a little more HP and TQ. But if both are shorty type then the decision is Supersrpint stainless or Evosport mild steel with a ceramic coating.

You had your computer reflashed? What did it cost? I have the Evosport stage 1 with the SL55 intake I had no idea there was a stage two reflash.

Can't wait to hear what you think of them after you get them installed. I had contacted JP performance some time ago about the gains, I think they quoted 30 HP on Vadim's car without any mods.

TC32AMG

I thought they would fit as the supersprint catalogue uses the same part number for all the 3.2 litre V6's. What did you do with the supersprints?

I brought it from BMP they are Supersprint dealer for North America. they took the header back. The header can't even get close to the cat. So i am wondering about if the C32 header is long enough and can fit. Hope someone in evosport can tell us more about their header.

TC32AMG

Good thing they took them back, they are pricey I got a quote from a shop in Vancouver and with the exchange and duties they were running 3.5K, and I heard it takes a while to install them too.

yes they are i almost **** in my pants when i got a call from the MB dealer they won't fit. I would be very happy if evosport can make something that fit my car with that kind of pirce.

Man, when I go into the performance businessI think I wanna sell BMW and Mercedes parts. You guys pay a MINT in this stuff. I want to be on the profit end of that. :v

How difficult is the install of these headers? Is it a simple bolt on or are they hard to get access to or require any cutting/welding?

tery

from what i knwo they should be simple bolt on. But there is a very limited space for u to work on. When i had my supersprint put on took around 4 to 5 hour and take another 2 to 3 hour to take it off.

there nice and clean! :p

Vadim @ evosport

Let me see if I can answer some questions:

SRT6 is based on R170, previous SLK. Headers are different from C-class to SLK. They will not fit.

Our first version did have equal length. However, it is almost impossible to manufacture due to very tight bends that are very hard to source. This is the reason for a simpler design.

Aaron had his coated with a different coating. In production it will be HiTemp titanium.

Typical install is six hours.

vadim, will you guys make headers for the slk 32 amg ?? and i was also wondering if the pump used in your e55 cooling upgrade will fit on our cars ??

Vadim @ evosport

If you are willing to bring your car to us, we can make SLK headers. Contact brad@evosport.com for further details.

As far as cooling upgrade. There is no room to add a secondary heat exchanger up front. However, we can make a kit to install bigger pump on C32. Pump should be worth some temperature drop.

amgstyle

vadim, if you can make a kit that make the bigger pump on 32amg i'll diffently get it. but will it also fit the slk 32 amg ?? and how much is the pump ??

M5KILLR

equal length headers are used for non sc vehicles only to allow the air to escape the quickest possible way. but with a sc the air is pushed out and an eq lenght header wont give additional performance

SteveL

Count me in for a pump kit for an SLK32 as well. I've thought about doing it myself but having a kit with the pump, hoses, mount, and clamps would be so much more time efficient.

SaabTuner

I beg to differ. The primary reason for equal length is so that the wave-motion in the exhaust manifolds is tuned the same for each cyllinder. Otherwise the VE between the cyllinders is not the same at any given load-point.

Supercharged engines just don't benefit as greatly as N/A engines do because the supercharger's pressure acts to force any remaining exhaust gasses out of the cyllinder.

Obviously the C32's engine isn't at 100% VE, so some improvement can be made with headers ... and probably more improvement still with long-tube equal length headers. (Not that they would actually fit, just in theory.)

SteveL:

Give me a day to get a price quote and I will make a separate post on this topic.

SaabTuner:

C32 engine is way over 100% due to the kompressor. In our testing we have not seen any difference in power curve between equal length and unequal length. A significant increase in cam timing would make the theoretical difference be more apparent in real world.

SaabTuner

I suppose I shouldn't be too suprised. How far above 100% are we talking? Beyond 111% VE (533 cc's + 59 cc's combustion space) the exhaust begins to suck intake gasses. If you go beyond this, there could be "problems".

Was there any testing with long-tube headers? They'd need to be fairly long to make use of the first scavenging wave.

Adrian~

SaabTuner

Waaaait. I know what the problem is: Extra exhaust scavenging doesn't increase compressor-flow. If your compressor is pusing XXX amount of air, extra exhaust scavenging just lowers EGT and manifold pressure ... but without increasing mass-flow.

Less pumping losses, and less heat, but only a small addition in power.

But, with less heat, you can tune more aggressively ... so you can get more power with pullies and an ECU upgrade. It suddenly comes together.

Adrian~

p.s. (I'd still love to see what the effect of long-tube headers is on EGT.)

Vadim, any update? Did I miss the thread? Thanks.
