Some more info about the SLS intake manifold
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.

You need to re-work your hood to make it fit as well.
Realistically not even sure what we can net with this thing on a FBO car. Any guesses?

I’m pretty sure it’s in the 35whp range.

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.

That box is the oil tank for the dry sump

This is interesting to me, but costs vs a S/C. Makes no sense imho.

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.

With raised rev limiter to 7400 - 7500 rpm it should be working fine !

jumping to a 3.23 will make our 3rd gear almost feel like second.
