I decided to take a look at the SLS intake manifold.
It's not sold in one piece like ours.
There's a top cover that is not expensive, it's like $300, there's a main and lower box that is around $2000 and there are the guts that are around $3000.
The guts have a separate part number for the SLS black series and I'm not able to pull a price for that. But I wonder if the extra HP that the black series had vs the normal one, once again had to do with an even better manifold and even better cams.
It's possible that the lower box includes the throttle bodies but I'm not sure of this.
Are you thinking of replacing the M156 manifold with the M159? Would that even work? I assume there would be enough hood clearance if people are bolting superchargers to the top of the M156. Although expensive, sounds like and interesting project.

I was planing to install the SLS manifold in my C63 AMG but now the car are sold ;-) The prefacelift C63 AMG gearbox cant handle that much extra tq as the facelift gearbox can. That was the reason to stay NA with the SLS manifold for getting more power and not that much tq.

Tasos has a few youtube videos on a c63 they put an M159 intake on
I think over 600 hp crank are possible - my C63 AMG with ECU + TCU tune + headers and sport catalysts was making 574 hp at crank and running 100-200 km/h at 8.0 corrected
Does anybody know what the functionality of the center box is?
This is the box that shows between the two air filter boxes in pictures of the M159 engine.
Is this the equivalent of the vacuum reservoir of the M156 at the back, by the firewall?
And what about the wiring harness? I'm guessing that the wiring harness needs to come with the intake manifold and hopefully its a plug and play.
As far as the two throttle bodies, I was never sure if the M156 ones open together, or sequentially. If they open together, maybe the engine would start with the M159 manifold on. If not, it will probably not.
Then again it seemed that Tassos started his before tuning, or so it seemed.
The loss of torque must be something too, as there is no variable manifold anymore and the cams are not M159.

There are member on here who are making north of 500 WHP with just basic bolt ons.
This is interesting to me, but costs vs a S/C. Makes no sense imho.

The M159 cams are much less pointy than the M156, so the valves are open a bit longer, I would really think you would want the cams and airbox together and then tune it to match the flow and timing. The M159 revs higher also, so it is really leveraging the additional high RPM flow and valve duration to make the power as the M159 makes the most HP at 7-7500 rpm
My guess is 50whp for the sls intake. However get ready for a dive in torque probably 50wtq loss.. Without the variable runners on the stock intake, you'll be hurting especially down low where all your street / daily driving is happening. Sls is about 500lbs lighter which makes a huge difference. The black series rev's to 8000rpm so Id imagine it's intake has even more torque loss, but higher ultimate hp especially past 7000rpm. I hope someone actually does this. A tuned sls with long tubes is a very impressive car. For a street car it'll just feel like you gained some turbo lag lol.

While people have posted this, I feel without E85, race fuel (anything over 93 octane / pump fuel) or nitrous these are b.s. claims and hyped numbers.
Sure these cars lay down quick 1/4 mi times but their MPH is very lacking and that tells the real story.
A blower car is night and day from a bolt on car. Power isn't only about peak numbers.

Just change the rear diff ratio from 2.82 (stock C63 W204) to 3.23 for example (SLS AMG does have 3.67 ratio) then your tq loss will not that problem.
Can he tell us how to program the car for it? I have a diff sitting in my garage waiting to try this.
jumping to a 3.23 will make our 3rd gear almost feel like second.
Another good friend of mine from Germay can reprogram the TCU for you - he also write ECU / TCU maps for some famous tuner in the USA - more with PM ;-)
