My next Step....
look here
new M113ML intake valves, M155 exhaust valves, new cams, new springs, new rockerarms, 80mm TB......

i dont know how many HP i increase.
these heads, are one step in a endless troublesshooting arond "missfire".

I hope with the larger valves to 2 mm, and the ported channels, get more filling, without ohter camshaft.
because of the larger valves, I have others valve springs, that are based on underlying and possibly measured in accordance with disks
how much compression you see as the ideal point for the M112ML?
The heads are now quite easily planned, and I did not really significantly increase the compression.
I hope the text is understandable, it is the Results of an "online translation"
It looks like your head port work opened up the throat area under the valve seat. Did he enlarge the throat area as well? Did you cut the valve seats to have a 3 angle or 4 angle valve seat?
Thanks in advance if you have some answers to these questions.

The M113ML & M155 valves are larger by 2 mm valves than the M112 ML,
I also used a new valve seat rings and valve guides.
the new valve springs because I have to look up whether is an OEM MB part ....
the channels in the compressor housing are also worked, just as the air
collector.

The next part is nice, the air introduction throttle -> compressor
is from a crate krabbel a tuner, including the asymmetrical holes for the 80mm TB, see for yourself

before the outlet ports in the area where the cusps is has been processed, I cut an old cylinder head, and saw there a water canal running :-(

The Best of Mercedes & AMG
Last weekend I finally managed to comb the parts installed
during the disassembly I found a broken cat again

and a failure header


assemble in reverse sequence



gasket

chain with new M155 aka "SLR" camshaft gears whitout rubber coating


whit the 80mm TB, and full 55k intake

complet

new ECO-mod on dyno coming soon............

Did you mention the use of slr camS, must have cost a fortune if so.
What did you do about the broken headers and cats?
I'm thinking we need to look more into the m112 3.7L engine block, I think there's a lot of untapped potential that we have not done. I recently read a few articles on a set up and it was able to make around 500whp.
of factory 3.7L 97mm bore and 84mm stroke has, and uses the same crankshaft as the 3.2l. variants.
the brabus 3.7L, has 91mm stroke and have "only" 92mm bore.
with 92 mm bore can also be enhanced "c32" used motor block. with the 97mm bore will not do, only as "NA" engine is the "little" block with 97mm bore preserved
expansion as the last step would be a factory 3.7L block with 97mm bore and the BRABUS crankshaft 4.034L result ....
the 55K (V8) have 92mm to 97mm bore/stroke ie with other rods, one could use the original pistons 55K
I'm not sure if I want to drive this effort yet, a C63 but is also a nice car .......


thats all a hobby, and cost you a little money

a lot cheaper and potentially faster than a C63 with 500hp.
You may have a difficult time reading this website, but take a look at it. I believe this is a C32 estate that has gone with the m112 3.7l block and heads and retained the C32 supercharger and other components. He used a 58mm supercharger pulley and a 182mm crank pulley and he's almost at 1.4bars. He also used pistons and rods from the m113k engine and the c55 exhaust. He's claiming 500hp and it sounds like it could be possible, but you never know. Take in mind it has been translated from Chinese to English, so it may not make a lot of sense.

Here's another cool link that has a c32 with a m112 3.7l engine and different supercharger.

we go here in Germany also times longer stuck very quickly, there are the highly tuned engines, but usually quite vulnerable.
by the whole performance is a C63 a completely different league. so I do think a little about it to buy next or after next year a C63.
build a 4 liter M112 you need a compelling original 3.7L, they are still very expensive for us here -> 5-8t € is just too much to use only the housing
you need to get first 6 pistons and rods from an 55k engine, then a 350 motor beside your c32 engine, disassemble the 2 engines to the last bolt, and assemble one engine consisting of:
- c32 crankshaft
- 55k piston and rods
- 350 cylinder
- 350 heads including c32 camshafts and valve springs.
At the end you don't know what compression you will have(you need 9:1)
and you will get lower lower boost.
Get a wet nitrous 50-70 shot below 1k$ and you will get same or more result.
The M113ML & M155 valves are larger by 2 mm valves than the M112 ML,

I remember reading that the design of the E55 supercharger housing was changed to include a bypass valve for safety issues, but the C32 and some 2003 and 2004 55 models did not have the bypass valve. I wonder if that housing is just an updated 55 housing. Take in mind the only vehicles that are supercharged are the 55 and 32 models.
Also remember, that 80mm throttle bodies are actually 78mm, but I could be wrong on that.
Here are a couple of pics of my E55 supercharger housing and the audi and mercedes throttle bodies.
