One thing I definately am interested in is the taller rear diff gearing from the C350...1 shift to 60

This whole time I was under the assumption the M111 used the M45 and not the M62. That explains alot!

The larger M62 I think was used on the 1st gen supercharged M111, which sported an electro magnetic clutch.

Okay guys, what's this project about? I'm always willing to be a guinea pig. And that M271 pushing over 15psi was yours truly
. Would I even be able to retrofit an M62? i.e. Room?

Actually, if someone could look into our intake systems and injectors (size - rate) that would be awesome since there will be drawbacks in ramming more air into the internals.. especially a pullied and ported M45, right? Don't let me go in it completely alone guys.

Some review images to keep handy in this thread (dimensions of each charger):
![](http://i16.photobucket.com/albums/b32/flipachu/eaton_MP45_Drawing.gif)
AND
![](http://i16.photobucket.com/albums/b32/flipachu/eaton_M45_drawing.gif)
Obviously there are size differences.. one would have to look at the dimensions to see what would fit and not.
M62 and MP62

![](http://i16.photobucket.com/albums/b32/flipachu/eaton_MP62_Drawing.gif)
I would like to add that these two superchargers are the most 'ideal' for these size engines. The M62 is already requiring 2.0 to 4.0L engines. Do I hear a retrofit MP62?

Hm.. nevermind.. I just spoke (and I mean literally) to a "very reliable source" about us trying this out. Basically, don't do it. :\. Get kleemann headers instead

Replacing the supercharger isn't going to be a riceboy bolt on level of difficulty. However, the biggest stumbling block I see is the form factor of the M62 outlet. Not that it would be too hard to piece something together, perhaps using some old SLK pieces.
Think cheap. The big guys have the money and resources to make everything from billet, and spend weeks designing a new part. Not everyone has big bucks to play...you might, since those Kleeman headers aren't making you blanch.
The M62 actually would be my last choice for a replacement. Its just bigger, not any more efficient.

How much did your car dyno out at, with 15psi? Isn't heat a big problem with the stock intercooler right now?

It was that or an ERL water/methanol injection retrofit (which I really don't mind).

I'm not saying I've got the cash to burn, I'm doing what I can to keep this engine and its mods alive (a la Young Doc, nuclearhappiness, and whoever else I missed who has a passion for their M271s) -even R&D/custom fabrication. Also, remember I have my "resources" and connections to work with (of which I can't mention here, haha). I'm coming up with ideas left and right for our engine to squeeze every ounce of power its got (or is capable of). How come I don't already have 2-12's in the trunk, right?
![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)
Hrm..Maybe I should throw up some pictures of 'our' limited edition fabricated intake that I also guinea pig'd for.

As far as the methanol injection... Works great! We installed it on the Cobra. On a day that was about 90 degrees and 85% humidity, we pulled 45x with out it, and after adjusting the carb and timing and when the methanol kicks in we pulled 480 (which is what we pulled before the methanol, but on a cooler drier day). When spring rolls around, we are going back to get it dyno'd again. This time it should be over 500 HP at the wheels.
Anyways, I digress! We wont get those kind of gains obviously, but I do think on hot days we will not loose any power.
I also had an idea for the IC. What about switching to a water/air intercooler? This way you can always make it cooler by going to a bigger radiator without affecting the air flow. You can even add multiple radiators if so inclined.

Porting my IHI supercharger
About halfway done with it. On the left, ported to 80 grit; unpolished. On the right, it hasn't been ported yet, but you can see how much material is removed at the score line. There's also the bottom side and the opposite side of the supercharger outlets that needs to be ported and polished.

I'm not doing it. I don't have all the tools nor the time to take apart the engine and do a complete job. Plus, I didn't want to mess up and waste a brand new engine. They're going to check the flow rates on each cylinder. I asked about the fuel delivery issues, no change in A/F ratio, just higher flow rate.

Pshek's twin screw blower is what we really need. Lysholm me please :v
Can't wait to see this thing in action when its done. Youre swapping the entire motor, right? Not just bolting on the blower, iirc?
