>>So you want to turbo your modern Mercedes? V6 and V8.

[Max Hughes]

How about a 100 so I can drive up there and turn it into a monster?

[Milkm4n]

i might be a bit behind on the subject but your saying you can turbo my 2.5 v6?....

if the answer to my question is yes then ..... how much and when


if the answer is no than sorry for wasting you time making you read this comment

What performance gains would a V6 CLK 320 (W208) have?

I'm overseas so I am trying to figure out who could tune the ECU or is it enough just to run the PowerChip ECU flash?

[Max Hughes]

The powerchip wouldnt work, use the AEM FIC6 I listed in my previous post. As for performance gains, you probably get 70-100 more horsepower with a 6-7 psi spring. Probably more since it's a dual plug 3 valve motor.

[Max Hughes]

In answer to some recent PM's here is an M112 auxilary bolt. It is the same bolt used in the m113, m272, and m273. It is located facing foward on the front of the engine just below and to the left of the oil filter canister.

The auxilary bolt is replaced by the 12x1.5mm to -3AN conversion piece to feed pressurized oil to the turbo. Its after the oil filter too so it's clean.

The auxilary plugs on the M112, M113, M119, M272, and M273 all use the same 12x1.5mm plug as pictured and verified thanks to Lowes :

[Mu9enx]

Will my car smoke 335i's with a rear turbo?

Realistically, what would an extra 70-100hp net for a 3800lb m112 sedan that only has 218hp/221tq stock?

I really wouldn't mind doing something as adventurous as this, since my car is going to be outta warranty soon, but I want to know if it's going to be a good investment?

[Max Hughes]

I don't know where I got 70-100 horsepower from. I was probably typing while I was tired. Your 320's will respond like my 320 except you will make significantly more torque than mine and the engines will respond better to the boost with the dual plugs and three valves. Plugging in all the parameters for the 3.2L m112 with a 6psi spring on a 70F degree day your car will be making around 320whp(ironic) or 375bhp. A little more than a 335i lol.

[Mu9enx]

That's what I like to hear!

Really thinking about it in the long run, is it possible to run a larger turbine to make even more power? Or will it compromise the engine if I wanted to up the boost to 1 bar? How many psi will our motors be able to handle as a DD?

[Max Hughes]

On the stock engine I wouldn't want to go over 9 psi unless the car has low mileage or the pistons are replaced. 1 bar is too much for the high compression, I would get 9:1 pistons from ROSS for 600-700 if you want to boost 1bar-1.8bar with a Masterpower T70 turbo.

[Mu9enx]

Just to be on the safe side, with the boost upped to 8-9, what then would the power figures look like?

[Max Hughes]

Using the same parameters I'm getting 345whp and 362whp or 405bhp and 425bhp respectively.

[need2speed]

I was pointed to this thread from another forum because I was interested in the STS system for my M119 motor. Great discussion and lots of knowledge here!
Max, do you have a similar parts list for a single turbo M119 install? I'm interested in your recommended components that would improve on the STS kit parts.
BTW, the install on your motor looks very very tidy

[Max Hughes]

Thanks. Use a Turbowerx EXA-Pump oil scavenge pump and a 3an full flow oil feed instead of the 4an feed and shitty oil pump STS supplies. Also have your valve cover tapped and welded instead of drilling a hole in the oil cap for oil return.

Is your M119 Jetronic or Electronic Fuel Injected?

[ZorroAMG]

If need2Speed doesnt answer first, I believe the 500E M119 is electromechanical fuel injection. He may be using a standalone like SDS or megasquirt...I could be wrong though but that's what you need for the M103 to turbo it properly.

[ddmracing05]

Im still waiting!!!

[need2speed]

[Max Hughes]

[need2speed]

OK, thanks Max. I found a local STS dealer and we'll chat...

[GLK4matic]

Anyone happen to know of an MB dealer in NorCal that would service our rides and not Chuttoyy us.....errrh...I mean Code8 us if we have a turbo? I know it sounds like alot to ask, but it is worth a shot.

[TemjinX2]

[GLK4matic]

As long as he leaves all emissions equipment on his ride he will be fine when it comes time to smog his ride. Cars that have turbos burn cleaner than cars without.

Y'all have probably seen it twice over but just in case... Hersh's CLK430 Turbo. Interesting tid bit: At 90 some thousand miles his pre cats basically collapsed prior to the install of the turbo and his cats were getting burned. I will now make it a note that if you go into a rear mount turbo, do a couple WOT passes prior to turboing the car and if it doesn't smell like rotten eggs(the age old sign of melting catalytic material) or throw a code then your good. Upgrading to metal substrate primary cats and deleting the pre-cats wouldn't be a bad idea either.

Max Hughes you are a genius. I'm from MBWorld and I heard you are a turbo monster. Can you be soo kind enough and give me some detail to set up a turbo on a w203 m272 3.5?

I have no clue about turbos but like you I am not a huge supercharger fan. To be honest with you turbos run in the family but i'm complete clueless.

Thanks Max,

once I get this done you know i'll be representing your shop or you (put a Max Hughes sticker on my car)

Can I mount the turbo before the exhaust? What about tuning? I will need an ECU tune? How would I handle the fuel/air?

Thanks,

Karo

[Max Hughes]

Yea there is just enough room in the w203 to put the turbo in the engine bay but a rear mount setup could be done more easily. It all depends on what you want. The AEM F/IC-6 will take care of the tuning and it is the anwer for all 3 of those remaining questions lol. It is the tuner, it tunes the ECU and it controls the fuel/air mixture.

[brabus247]

what happened to hersh's car?? he went a bit quiet

[jk062602kj]

[Max Hughes]

[SLAMMED_C]

[Max Hughes]

Yep. All the Mercedes motors since the m103 on have 12x1.5mm plugs in the filter housing.

[dokotela]

hi there max.
very interesting indeed.
what are my options considering i have a m111 kompressor engine?
how easy would it be to twincharge with a remote turbo setup?

any/all info would be greatly appreciated.

[Max Hughes]

You don't need to do a remote setup with a M111 kompressor powered car. While the supercharger obstructs access to the oil pan you can use a small scavenge pump and send it back through the valve cover or pump it around the S/C into the oil pan.

I have been putting a lot of thought into twin charging and I think that if done correctly you can maintain all the stock functions of the car including the secondary air intake without bleeding the boost out. That simplifies the parts needed and allows for a simple AEM F/IC tuning computer to be installed instead of going with the more expensive ECU flashing route.

[dokotela]

you got me confused.
how about a little rough sketch to show how this will be done.

[Max Hughes]

Never mind about the secondary intake I suggested, it will have to be removed but it can be nullified.

Just picture it looking a lot like this picture but the supercharger will still be attached(in the stock location it is right below the turbo). Your intake will also remain stock unlike this dudes. This is "Pagz" from peachparts.com

[Max Hughes]

Hmm what did these baby's come off of?



Cant wait for these suckers to come in so I can rebuild them into something much more interesting

[Williams707]

CLK W208 or E W210

[Max Hughes]

W220 But they are going on a W208 once completed . Hoping for cross compatibility between most of the M113 equipped models with this design.

After that the m112 is finally getting some boost.

[Williams707]

I was so close but they do look similar Since you mentioned a W208, I'm guessing you are taking a trip to New Jersey or he's doing another road trip to IN or a new W208 project?

[edrisennab]

i own a 2005 clk320 with an automatic transmision i was wondering if i could turbocharge it????

[Max Hughes]

Yes it can be turbocharged.

[DuaneC55]

Not to question the post, but "no turbo lag" is a bit hard to beleive with this rear mount system. Look at the distance between boost side running from the rear of the car to the engine. Turbo's also thrive on exhaust manifold temperature, most of the thermal value is lost by the time the exhaust reaches the back of the car. The only way this system can acheive "no turbo lag" is to use a small turbo that comes on boost just off idle. But this will kill your top end. The only manufacturer that puts turbos in the rear of the car is Porsche, but the engine is there also. You can try to fool the physics of volumetric and thermal efficiency, but it’s unlikely you'll succeed.

[Max Hughes]

By no turbo lag I mean if you brake launch from a stop you will be boosting immediately once you take off or if you punch it from a roll.

The easy way to counter act turbo lag is to use a smaller turbine housing while keeping the same compressor housing. It's not rocket science. It's what every remote mount turbo setup will do. You have the same size turbo you would have used in the engine bay with a smaller exhaust side.

Heat creates a higher volume of gas, it does not change the velocity of the gas. The turbine housing is what manages the velocity of the gas. In a traditional setup you use the bigger turbine housing instead of a small one because at higher RPM it will build up excessive back pressure and reduce efficiency. The remote setup can use the smaller turbine to maintain quick response but because their is less heat(hence less volume) it will maintain the same or better levels of efficiency at WOT on the exhaust side.

I'm on board for this,...
