I'm very surprised no body has made a turbo kit for the m156/c63
I'm very sure it's possible

I know weistec has come so far with the supercharge kits but why not turbos??

Maybe some of the experienced tech guys can shed some light on this subject

I see a lot of holdens/chev owners dropping there supercharge kits for turbo chargers so why not Mercedes???

The M156 seems to be shoe-horned in the engine bay as is... Where would the turbo(s) and all the plumbing fit? The Weistec SC replaces the stock manifold, so seems straight forward- trade-off (replacement). Real estate under the bonnet seems to be a challenge for a turbo, additional plumbing and maybe larger intercoolers...., but I'm sure it could be done.

I would love to be able to go turbo someday as well, but lack of real-estate under the hood is definitely an issue, but also room up front for an intercooler would be tight as well, very busy behind a C63 grill? I'd also like to see a centrifugal blower option as well, as I think the linear power-band a centrifugal blower provides would match the already high rpm power band the engine has naturally.

For those who are brave, take a look at STS turbo systems that move the turbo's to the rear of the car towards the end of the exhaust system, maybe some custom plumbing could make it work??

Yep not enough space in the engine bay for turbos is what holding off tuners to think about this solution.

Merc63

Maybe rear mount, but what's the point? The blowers are instant torque off idle and scream to redline.

CarHopper

Here's a CLS55 that has a twin setup. Notice where they had to put the turbos though...

Not worth trying to do it. Want TT? Get the new C63

skaarlaj

I'd agree with the instant torque of a pd blower, but both centrifugal blowers, and turbo's will embarrass a pd blower at higher rpms at a given similar amount of boost. I love the Wisetech blower for these cars, but honestly believe a centrifugal blower at similar boost would be simply amazing on one of these cars, and of coarse turbo would be even better

mr747

just for something different

Look i totally understand there is no really enough room im just surprised no body has tried thats all

these days power junkies try just about anything with cars these days and im just surprised no body has tried a turbo conversion

Check out this year's Merc AMG Formula 1 cars (and engines/power units). They've created a novel way of locating the turbo, at least to my knowledge (I don't know much about this stuff). The turbo is now at the rear of the engine, which keeps it cooler and has other benefits as well. It was a massive engineering development in F1 and because of it (in part) Merc/AMG are well ahead: http://www.wired.com/2014/04/mercedes-f1-turbo/

Why the hell would anyone want a turbo when you have blowers? Do you enjoy getting stuck between 2 lanes when you try to overtake someone because the turbo didn't kick in yet? Turbo lag sucks, no matter how small the lag is. Weistec FTW.

roadtalontsi

thats what i was thinking. Why would you not want instant off idle torque? All turbo's have lag some better than others. The bigger the motor and smaller the turbos the less noticeable it is but it's always there. I'd know best being a supra owner

Merc63

My friend has a mustang with a procharger on it. I blew his doors off hard.

He was still coming off the line and I was halfway down the track...

The procharger is so damn loud too, it sounds like a F16. Stupid loud.

Jacob-63

Ive seen a procharger Mustang beaten by an OE Tuned/Header C63

sinape62

Being an engineer, this is interesting. I've seen the layout in a CAD like view, it was quite innovative. Perhaps something we might see in future AMG in years to come?

Southways

Yes ... I might be a little biased, but;

Really? I have seen/done quite a few replacements of Holden turbos & hairdryers (centrifugal blowers) with positive displacement superchargers, but I have not seen one road car that has replaced a PD supercharger with a turbo.

Linear drive of a centrifugal?? You must be kidding.
I have yet to drive a centrifugal blown car that was not like driving a two-stroke motocross bike. Push the pedal; nothing; nothing; nothing; massive uncontrollable wheelspin; rev-limiter; change gear; nothing; nothing; nothing; etc.

I have only driven one STS rear-mount kit (4th gen Camaro) ... the lag was so bad it was like you had to phone the turbo in advance if you were planning to overtake.

TTA850

I personally like n/a engines, that said the turbo setup on that CLS is quite nice - I'd love to see that on a C63. PD supercharger are great and can make excellent power, but the quickest and fastest cars I've seen at the track and on the street are centrifugals and turbos. With modern thinking they have minimal lag and more linear curves while making more power and controlling it better. Keep in mind I'm not talking about off the shelf kits, but what can be done is impressive.

mr747

There would be minimal turbo lag with A 6.3 litre with 2 decent sized turbos

Reading the forum about the m157 and looking at the power there producing it just makes sense that the m156 would be a complete weapon with 2 turbo strapped to it

Knowing the limited technical content in this forum, this thread may end up breaking the record for more generalizations and e-myths than any before it

Kriston

I think you may be on to something!


Fellas anything is possible with the right $$, I know that Heffner performance was talking about building a turbo M156 a while back.


You can definitely fit a pair of snails in the W204 chassis with the M156.


It will be epic to see someone do it. A lot of time and effort, but will probably yield ridiculous power. I remember the review where Chris Harris stated that the tech engineers at AMG laughed at him when he asked what kind of boost the M156 can take. Its a tough motor. It will handle the boost well.

CarHopper

Must be driving in some pretty fast moving traffic eh?

There are pro's and con's to each.

driftmotion

I think a set of 30r where the exhaust manifolds meet the mid-pipes.... I think it could work.

CarHopper

^It would take so much piping on the c63 though. A blower is the best setup for a c63 but not for all cars.

msheredy

Here comes the same rhetorical turbo vs blower BS. There are, and always have been, pros and cons to both. Everyone knows of a person who knows a person that had a blower car that whooped on a turbo car and visa-versa. To say one is better than another is simply ignorant until you have the 2 to compare against.

I was actually hoping Weistec or AMS would have developed a turbo setup by now but with the 156 platform hitting its plataue I'm not sure how reasonable that would be.

mr747

i was just reading in the e55 forum and it seems a couple of those guys are also going down the turbo route

RNS-11Z

If I wasn't building my lsrx8 my c63 would of had a set of turbos on it by now
