Stumbled on this at the Festivals of Speed. This is the newest upgrade on the C74, no info on power gains.

Thanks Howard. Are those also new throttle bodies and upper intake manidfold? It addresses the shortcomings of the small intake box and pretty cool that new air scoops direct air to the cone filters. The last airbox was costly and this must be VERY costly........

EDIT: Is this an SLS style intake adapted to work on a M156? The uppers are different from the M159 but how about the upper intake manifold?

AMGC60-3

WOW, very interesting.

mthis

Interesting but how much will it cost?
The CF air boxes are 3K what this going to be 5-6K for 20-30HP max

Dads C63

I think they will be way more than 5-6k. Probably double that IF they offer them to the public. Sometimes they keep special items like this for their preferred customers and I understand that.

This looks soooo sick. I want one bad. But, definitely out of my price range. I love the design of the air being fed over the cones to cool them.

That is the first thing I thought when I saw it. The SLS motor sits much lower in the frame affording room for the big air boxes up front but this is an interesting approach. The reps weren't saying much about it I assume because it is still an R&D product.

Carlsson have something similar to this in their CK63RSR I think

Oh man that is sexy!

And the KW remote reservoirs!

Very tasty, but the $$$ per HP must be off the charts.

Sincity

Do you have a link to a pic?


EDIT: Is this it? The Carlsson has a raised hood to fit this.

Very cool!

Maverick1975

Yes that's it, I love the bulged bonnet on that thing

blindfold

very interesting looking, guess they are also going with a cold air induction, wonder exactly how much lower the IATs will be

jacob502

I would buy the carlsson product. Pure German baby. I wonder if you could still fit the weistec supercharger when you have one of these...?

dodger63

So you must have one then

Dads C63

Mike,
Nope, no Renntech or Carlsson. Mine will be a true ram air hood with nothing coming from inside the engine compartment where the hot air resides. Thats all I'll say for now. Stay tuned.


I'm not sure Renntech or Carlsson will improve the air flow of the stock intake. The actual flow and volume has never been the problem, just how we get the air to it. No one is boasting HP increases? I wonder how they get past the ECU runner changeover(short vs long runner). I still don't like taking hot air from inside the engine compartment but thats just me.

AMGC60-3

Thats what I have been thinking about for a while now, how can these "cold air" intakes be beneficial that are pictured above from Renntech and Carlsson. All Benzes already more than less have cold air intakes stocked and they are not sucking in hot air from the engine bay. Any one have a good answer, please chime in.

PetroC63

This is going to be epic.

I agree about the engine compartment heat, now if they had the same setup with some kind of hi temp plastic cover/box on both sides shielding the filters from engine heat it might work better.

dodger63

Yes the one pictured above looks like a hot air intake to me

Sincity

I thought it was mentioned somewhere that the OEM box top volume was too small?

SonnyakaPig

Bingo!

SonnyakaPig

No, because the blower sits on it's own specially molded intake manifold.

Multispeed

I agree with Dads.
An unsealed/open filter area sitting in the engine compartment is neither a proper cold air intake or Ram air.
In respect to the ECU and wires that connect to and control the original 2 stage variable length intake manifold, I guess the wires just get bundled and zip tied out of the way since now there is nothing to connect them to.
This to me is the real significance being overlooked here. With this Renntech setup is the replacement of the stock variable length type of intake manifold in favour of a fixed runner length, high RPM design. Really this Renntech prototype manifold style is just like what is used on the SLS M159, Mercedes V12 in the Zonda, BMW M, Ferrari and others.
From the photos it does not look like they have incorporated telescoping variable length velocity stacks in there. And it looks like they are using SLS throttle bodies.
Anyway, I think everything looks well done except the filters sitting openly in the engine compartment. Same with the painted blue SLS manifold that Carlsson? is selling.
It will be interesting what the dyno charts, track times and user opinions are with this manifold choice on the M156 engine cars. Despite the different camshaft profiles, will the power curves still look a little more SLS like? Perhaps with this manifold and a good set of headers the SLS M159 camshaft profiles will work more favourably?
Of the potential negatives, how about the likely drop in low-end torque with this manifold design combined with our cars that are heavier than the SLS.
I am very curious to see how this manifold performs...
In the photos notice the difference in the manifold runner style between the stock M156 and the M159 and Renntech design.
In the M156 photo you can see the little black flaps that open and close runner length and the shafts they are mounted on.
