They have these options:
Phosphate + Grafal
Grafal
Ferroprint
Ferrotec


I also called MB to see if they can give me the tech specs -- they mentioned StarTekInfo - its a subscription but they do have a "DAY" subscription for $60.
Does anyone know if I would be able to pull out all the deck, piston, rod, ring info out of there ?? Does anyone have it?

Alan Sakoman

So after weeks and weeks of waiting for parts and turbos to be built the build has started.
I'm going to the shop this Friday to check on the progress and hopefully will post some pics.

In the meantime I did do a "baseline" run in a Wannagofast event at the end of May.
I hit 127 MPH in a 1/2 mile shootout.

Hopefully a good measuring stick for after.


oh in the meantime I'm driving a 1987 Toyota pickup , manual with no A/C. Lifted of course like a boss.

gaspam

127 mph in the 1/2 must be a typo because stock should hitting in the mid 140s and tuned/Ltd should be in the low to mid 150s and s/c stage 3 has gotten up to 185

Alan Sakoman

Its not a typo. I had street all season tires, couldn't get any traction and this is the first time I've ever driven in an event like that - so probably bad driving.

I was hitting 114 at 1/4 mile.

It was Weistec Tuned with ROW airboxes only. No idea why so low unless I'm a terrible driver but I was shifting pretty much AT red line.

Amg63-

That's a bit odd as even stock NA 6.2 E63 should be at around 117-119mph in the 1/4 mile.

Alan Sakoman

I didn't do race start of S+ mode. I did Manual.

Maybe that was my problem?

gaspam

no something else must be wrong as if you are doing 114 in 1/4 and only picking up 13 mph by end of 1/2.

127 is incredible slow for tuned M156 in 1/2.... the c63 M156's with same mods as you are doing high 140s/ low 150s and there is not a ton of weight difference so you should be in similar range

are you logging?

Alan Sakoman

I didn't log. It was a couple of runs for fun.
I had the Weistec tune done through Eurowise here in CLT.

I didn't notice any issues with the car during normal driving.

We have to re-tune everything anyway as we put turbos on so I'll start logging and see whats going on.

By the way - what would you recommend for logging?

Lenin

Not to beat up a dead horse but I ran 113MPH at the end of 1/4 mile in my 6 Cyl. C32 AMG. Any time you tune the car and make major changes like turbos and pulleys, you have to log data or be prepared to pay the price.

Alan Sakoman

At the time of the run there were no mods done other than the normal Weistec tune.

We are going to re-tune and do extensive logging once we install turbos. Not really sure what you are trying to say.

Lenin

Saying two things:
1. 114MPH at 1/4 mile is too low for 5.5L twin turbo. Either something is wrong with your driving or something is wrong with the car
2. Any time you change factory parameters through software or hardware, I would strongly recommend that you start monitoring various parameters, like IAT, Boost, Spark Advance, etc.

In your case, you want to establish a good baseline before changing your turbos. But if you car is not working right (your half mile results), you don't have a good baseline. So, when (hopefully not) your car still not performing right after the turbo upgrade, you will not know right away what the issue is.

I currently only have a EC tune but I monitor things using a DashDaq.

Alan Sakoman

This is not a 5.5L TWIN TURBO you realize that right??
Its a 2011 M156/W212 - - it's 6.2L naturally aspirated

Lenin

This doesn't change anything I said. It is still too slow at the end of the 1/4 mile and 1/2 mile. Something is wrong and you don't have a good baseline before throwing money on a turbo upgrade.
And you should still do data logging if you are making software or hardware changes. You will be surprised what you would learn about your car.

Alan Sakoman

ok any recommendations on what to use for logging on Mercedes?

gaspam

best is to get dedicated wide-band w/ extra bung welded in exhaust once you do custom TT build but any basic app will be fine for now, i use obd fusion app on iphone with LELink Bluetooth obd

Alan Sakoman

Thanks for all the help.

LELink seems to be Apple only.

Any opinions on BlueDriver Bluetooth Professional OBDII Scan Tool ?
Seems reasonanble and offer a ton of crap for my make/model/year in live data.

As gaspam said, a dedicated wide-band w/ extra bung welded in exhaust will give you AFRs which is a critical measure. I use Zeitronix connected to my DashDaq. If you can find a Dashdaq for $300 on ebay, grab it. Dashdaq has ability to record various parameters onto a SD card to be reviewed later. Another advantage of the dedicated sensors is that they will give you a much more frequent reading vs. OBD2. With OBD2, the more parameters you monitor, the slower the refresh rate gets and therefore, if you run 1/4 mile in 11+ seconds, you will get a lot more accurate picture. So, IAT and boost, in addition to AFR would be my recommendations for the dedicated sensors. Then EGT and Fuel Pressure.
I just read more than a few horror stories post tuning and mods where people didn't even know what was happening to their engines and then throwing good money at the problem without fully understanding what the problem was.

gaspam

i've never used that one or seen it, but for andriod phones Torque app is pretty popular... I was going to get it but couldnt since i have iphone so i got obd fusion since its close to same as torque app

OBD sample rate is good if 2 to 3 PID are selected.

I was in your shoes about 6 months ago...I did a lot of research and talked to quiet a few shops...it's very hard to get that custom turbo built because of the lack of space and tuning. From all the research and talking to different shops I realized it would be more cost effective for me to sell my m156 and get the m157..and that's what I did...it doesn't mean that it's impossible it's been done it's just that it's going to cost a lot more than expected...plus with the compression in the m156 you wont be able to push it hard without going inside the engine and changing things...
good luck with the build and keep us updated...excited to see that beast with a tt set up

Kameron562

So whatever came out of this build?

id love to look into turbos for my w204

Alan Sakoman

Sorry to inform you but the build didn't finish. It was plagued with challenges.
First we spent months trying to figure out how to fit 2 turbos in the pocket right below the engine. We managed to get the pipes right and fitment but then it was how to get the pipes up into the engine. very little room, concerned about heat etc.
Then came the intercooler and short of redesigning the dang upper intake it was very hard to fit it anywhere.

All in all, lot's of sweat and trial and errors, hours but in the end I ended up buying a 2016 E63S AMG which is an absolute beast with the twin turbo 5.5. drives so much better too because it has the 4 wheel adaptable drive.

Don't get me wrong I absolutely loved my 6.2NA beastie too
