Well guys after weeks of work, an almost cut off finger, and many many beers, the Mercedes supercharger project is almost complete....Here is a few teaser pics for you before I tear it all apart again. (it is still in mock up and a few pieces need paint), I am also waiting on either a rrfpr or a custom tune chip..(HINT HINT....BARRIE FROM MIDNIGHT TUNING!!!!!!!), a bov, and a wideband 02.. THE END IS IN SIGHT!! I really hope it works!! Skid
Here is a list of parts (so far)
Mercedes Eaton m62 supercharger
custom sheet metal intakes
4 weber velocity stacks
LS-1 32# injectors
stock e30 m42 lower intake
timing belt idler bearings from a v6 Toyota
6pk-1965 serpentine belt
3 cases beer
2 boxes of band aids and a tube of neosporin

My finger after a month!! Grinders with cutting discs and no guards are dangerous kids!!! Ground a 1/4in wide gouge down to the bone, not pretty...Skid

Nice Skid
My finger hurts looking at yours!
Love the materials list, beer!
Did that m62 have a electric clutch? Mercedes do I recall.
Will there be uneven flow between cylinders with 1&2 getting the most?
What level of boost are you going for? Gearing for m62?
What advantages will the wide and sensor give you I have mine hooked up to a guage pod, only.
But there is 2 outputs?
Cheers Rohan

Yes electric clutch, will wire to 12v switched. Im not sure about uneven flow between cylinders but the downing Atlanta manifold is pretty much the same as my design (a log) with no velocity stacks.. I used the velocity stacks to try and get the intake runners a little longer and smooth out the flow. I am no flowbench but it seems right in theory.... Shooting for 5psi boost with the stock Mercedes pulley.. Plan on using the narrowband emulator portion of the wideband to replace the stock narrowband 02 sensor, then use the wideband to run a gauge for better tuning.. Skid

Yeah!!! My blow off valve just showed up! Thanks dude in the brown truck and tight brown shorts!! ...One step closer to BOOOOOOST!!! ...Skid

Very cool! I like how you made use of a lot of the stock intake parts, and the generous amount of free space in the E36 engine bay. I have always wanted to try to do an M62 retrofit.....always-on-demand boost is a nice thing!

I wish it was in an e36!! They have tons of room in the engine bay! It is in an e21 320i, NO room! It fits like a condom nice and snug... I even had to go to a remote brake fluid reservoir the intake sits right on top of the master cylinder.... Skid

skid, I like your money saving fabrications! post some pics of that e21 :_)

Well it looks like i f'd up and bought a blow off valve and not a bypass valve. I did not know they were different. I guess a bypass valve is open under vacuum but a blow of valve is not??? I figured they would both be open under vacuum.. maybe someone can verify? Since the supercharger will be making boost at idle it needs to have a bypass to send the boost back into the intake. The blow off i purchased is a recirculating valve, and opens with vacuum but im not sure how much vac it takes to open it. Will there be enough vac at idle to keep it open? This shit is confusing. A mind is a terrible thing to develop without an education!... Skid

Doesn't the M62 have an internal bypass that used engine vacuum to control?

The mercedes m62 uses the electro clutch to some how turn on and off the compressor for bypass.. I think..
I got the proper bypass valve today fron a audi 2.8 turbo.. the wrecking yard gave it to me free.. it should work just dandy!!!......skid

From what part the red one is building? A e30 intake pipe or e36 one?

Not sure what you mean??? Sorry...skid

I think what Arthur want go know is from which engine comme the admission parts where the injectors sits, that you actually painted red, is that from m42 e30, m42/4 e36?
-
Exactly! Sorry for my bad english...
-
It is a stock e30 lower intake manifold.... skid

Thanks :)

Well i figured I would give you all an update.. The car runs fantastic with the mercedes eaton supercharger!!! I got together with Jake from classic daily, best guy ever!!, and we decided to change DME's to a e30 from a e36. This enabled me to run his turbo tune for the m42. He scaled back his tune as I am running less boost and smaller injectors. The car runs great, idles perfect, and pulls HARD!! Its running about 7 psi boost at 6500 rpms, and is a solid 14.7 afm. Havent gotten it on the dyno yet but its really really fast!!!! THANKS JAKE!!! You da Man!!! Skid
-
Hi Skid
Why did you change the dme, to e30 from e36? Disa
Cheers Rohan
-
Hi darky! Since I had to build a new manifold there is no disa valve. Also, i couldnt find anyone that had a tune or could write a tune suitable for boost applications in an e36 chip. Would have loved to use an e36 dme because of its knock detection but it just didnt work out. I guess the e36 is a completeley different animal when it comes to writing tunes. I am not a tuner by any means thats why I called Jake B. ... Skid
-
Hi Skid
I just thought that the disa in the e36 programming would be the pain.
That makes sense with regards to keeping knock sensors. I can't understand why e36 dme is that much harder to program. What's does 14:7 afm mean?
Be interesting to see your dyno curve and your air fuel ratio curve.
Cheers Rohan
-
14.7 afm, the air to fuel ratio.
-
I hope the 14.7 refers to idle AFR only. That's far too lean for higher rpms/loads
-
Yea Collin thats at idle. Its around 9.8 to 10.2 w.o.t. ..thats a little richer than I would like but ok for today. Jake burned me a leaner chip I havent tried yet but I will give it a shot possible today....Skid
-
Wow! Very interesting!
I'm currently building a setup from a merc (m62) onto and m42 for my e10.
I really didn't think standard ecu would even be an option I've been looking at standalone!
Do you have any photos of your pulley set up? And sizes? And belt tensioning?
Are you planning to get it on the rollers soon? I'm not sure what sort of injectors to use yet also!
Also the bypass system? Have you used it or are you just running it under boost constantly? I've gone for a different set up with the manifold as I'm wanting to run an intercooler going I to a plenum as I was worried about tempratures
