OM642 Hybrid Turbo

[the88g]

Hello,

Does anyone know an indie who would help me with getting a bit more performance out of my V6? I'm not looking for anything silly. I'm aware the transmission in this thing are a limiting factor but I imagine ~310 bhp should be achievable (thinking dpf delete, hybrid turbo, exhaust upgrade and remap).

Please advise. Thank you.

Take it to MSL they are the go to guys for Mercedes

Buy a better car.
Is DPF deleting even legal. Why would you circumvent a safety issue and let your car pump more crap into the air.

 

[Crispian22]

Definitely go to msl!

They got 298hp and 720nm out of my previous E350.

 

[the88g]

Thanks for the responses. Yeah I did try MSL, they said remap only. Maybe the engine information in their database is incorrect for my registration? Otherwise seems a shame.

mioba - yes I suspect it wouldn't pass a MOT. It's a project car for a bit of fun except when it comes to mechanical work, I'm useless. I'm getting my hands dirty with the infotainment setup, talking with the canbus and electronics.

I'm not the type to put anyone off doing something as everyone has there own goals and projects but what i would say is these engines are almost impossible to make big power from, even on hybrid turbos, intercooler, gutted dpf and straight pipes your struggle to make much more than 330-340hp and no real extra torque over a stage 1 E350 as the box just cant take it, nobody really sells hybrids as there not a big seller, unfortunately Mercedes "flagship diesel" just isn't anywhere near the performance of Audi's bitdi or the 535d from BMW of the same generation, saying that though its proven that the bitdi isn't worth the hybrids and supporting mods over a stage 1 map either the cost to performance is just not worth it at all so no one makes the parts, difference is a stage 1 mapped bitdi will make a good 80hp over a mapped E350 but that's just something you have to live with i opted for the E350 over bitdi just because i preferred the look and interior of the E and that was enough to give up the bitdi engine (i think), so id just help it breath a bit and make it more reliable by gutting the dpf and get a good custom map and leave it as that, your still be around the 300hp mark and same kind of nm as a stock e63, just not as good sounding lol

Just to add your car will pass an mot with a gutted dpf just speak to msl they can sort it for you with the bloke next door.

That is really helpful mate, thank you very much. I shall keep it at that then.

I have the same car CLK320 cdi (without a DPF), owned it for nearly 10 years now. After 2 years of ownership I considered similar upgrades and very quickly made a list of mods needed. The following is the list from memory, this was 8 years ago so some details may not be correct;

1. Hybrid ball bearing turbo from newer 350 cdi engines. These are water cooled and would need to provide a water feed. (At the time roughly £600 for second hand reconditioned one, would fit myself so no labour costs)
2. Custom intercooler, there should be enough space to fit a larger one. (approx £500 depending on quality and size, would fit myself so no labour costs)
3. Exhaust upgrades (estimated £800+ supply and fitted from exhaust specialist)
4. Custom remap and dyno (minimum £500)

Total costs approaching £2500, this is with doing a lot of the work myself. I am sure cheaper alternatives could be sourced but personal preference would be for trusted quality companies/products. I quickly decided the cost wasn't worth the additional performance, a clk55/c350 cdi with remap would have been quicker and a lot less hassle to buy.

Happily still driving the CLK without any mods or remap. Still quick enough for fun and returns 40+ mpg on a motorway run.

I've got a c350 cdi w204 and it's got a Brabus D6 box fitted,its easier than a map,still shifts pretty well✌

 

[Carlos2k]

As mentioned, a remap will make hell of a difference! Whats the mileage of the lump? A good carbon clean will really help it, my prev car had the OM642 and at 140k the intake manifold ports were around 30% smaller with the amount of crud produced from the EGR and engine breather etc.

Taken to the right place you should easily get 270+ HP. Angel tuning in Banbury did mine, about 30miles from MK, decent bloke.

Give Alex @alexanderfoti , AMF Mercedes a call , he is in Kent and has done loads of om642’s

Hi

I have a w203 c320cdi with a hybrid turbo (gt2056v taken to gt2365), exhaust, intercooler.
I've been tuning it myself.
Had it on a dyno and it made 330bhp and 700Nm with 230kPa of boost (330kPa MAP).
I have since turned up the boost a bit to 260kPa. and it now does 0-90mph in 9 seconds flat. Not bad for an old diesel...

The pre-turbine is now about as hot as I want to push it.
Maybe I'll get a water injection kit at some point....

That's a summary of the build...

OM642 gt2056v hybrid gt2365v | Performance Lounge

Good evening all. I have a 2006 c320cdi 95000 miles. Cat internals removed. Swirl flaps removed. EGR has been blanked at the intake system. Recently installed a hybrid turbo, gt2056v with a gt23 turbine from a C30amg paired with a 65mm billet compressor wheel. Therefore turbo is now a gt2365v...

On om642.930 I've seen best stage 1 as 298 bhp, 660 N. M torque. Contact BenzNinja, he is the best MB tuner I've come across. The 722.9 tranny is limited by torque not hp. Aim for 640 nm torque and 300 bhp, you should be fine on stage. You can invest in a better BMC filter kit. A bigger turbo, better cam, piston sets, and an amg intercooler will set you ready for stage 3 with proper balancing. In my opinion go all out for stage 3. BenzNinja will even tune your transmission, but just get it overhauled for better performance, ask for the sport plus extra mode to be tuned. And swap out airmatic with eibach sport springs, delete egr, and dpf as well as add blue. Do change all the fuel injectors for better fuel delivery.

Not you again...

Google BenzNinja and see what you find on other forums... Not so much BN; more BS.

The 642.853 in my CLS makes 322 hp and 718 nm with stock hardware. It was remapped at MSL, so those figures are correct.

Yes, the 722.9 is torque limited; so "in my opinion go all out for Stage 3", spend a fortune on "a bigger turbo, better cam, piston sets, and an amg intercooler" and "swap out airmatic with eibach sport springs, delete egr, and dpf as well as add blue. Do change all the fuel injectors for better fuel delivery". All this gives you, guess what, more power and more torque, and guess what else? A broken transmission...

Is your opinion worth anything? Have you actually done any of what you blithely advocate? Have you ever had any actual experience of tuning and modifying a Mercedes, or are you just a keyboard guru wannabe downloading stuff from the internet and reposting it?

Lol easy to spend others cash isnt it, I got mine EGR and DPF deleted, and remapped its now at 298 and just a whisker under 702Nm, am now looking at a new intercooler to just help it breath a bit cooler in summer the standard one incidentally is actually great but 700Nm is about its limit flow wise , it will probably add a couple or 10 BHP as well, Exhaust will be swapped for a custom stainless once thats on, for that I always go to Cybox they have made the last few exhausts for me all hand made and tuned to the sound you want on site, thats probably the limit want to get or will get with the standard Turbo and injectors, a hybrid is possible but it always creates lots of smoke whilst the turbo spools IMHO not worth it for road use.
I will say even at its current state wet weather has to be treated with respect the MB anti skid is very good but it can step out easily even with very good tyres.

 

[Muckypaps]

What is a whisker under 702Nm ?
701Nm or a bit more?

 

[suty455]

What is a whisker under 702Nm ?
701Nm or a bit more?

Actually 706 Maximum but 701 and a bit on average overall over 6 runs

 

[E55BOF]

That's one-seventh of one percent. Let's just call it 700?

Love this banter, E55BOF is now in the lead, 1 up.
