c250 om605 200+bhp. 6mm element - mantahead - 05-08-2013
hi,
i have done some work on a c250 for a guy, pump is standard 6mm, for now.
turbo is kkk from Man truck
stainless 2.5inch straight through exhaust.
more fuel added by potentiometer.
custom downpipe.

went to the dyno today and i soon discovered from my egts and some experience that pump timing is out. Under further investigation i discovered some red paint marks on crank pulley, o dear, pump has been taken off by someone who doesn't know where timing marks are.
power started of at 188bhp and after a small advance i had 205bhp with 260 ft lb.
egts came down nearly 200degrees.
so, tomorrow i will check timing and maybe have to remove pump and fit correctly, i am nearly sure timing is still out.

RE: c250 om605 200+bhp. - bruno_pinho - 05-08-2013
interesting ...
I got 260hp with original 6mm pump
not only agree with potencimetro, the car is accelerated and the lame work ... with Reprogramation is better
RE: c250 om605 200+bhp. 6mm element - mantahead - 05-08-2013
260.
that is good power for standard pump, what is the max rpm you can get with remap?
RE: c250 om605 200+bhp. 6mm element - mantahead - 05-09-2013
any wonder pump timing is out, no timing pointer on engine.

Good results so far, is everything else standard, intercooler?
What's the plan for the timing, how did someone manage that?

i have timing pointer now fitted from another old engine and have no idea why someone would remove it.
going by the dirt in the threads, its been missing for a while.
pump coming off on monday. timing light says 16 degrees btdc.
would like to try some more advance.

nice job there Manta, Ive a 250 estate "98 manual put a 2.88 diff in and had ECU chip upgrade and DPF guts removed allegedly 175Hp 80mph @ 2500rpm now, because of gearing Im not using this engines ideal rev range for torque I need it <1500-2000+ and not 2000+
It pulls like a train over 2000 but terrible under and need to sort it, does your conversion with the KKK give better lower down boost, is it from a 7.5 tonner with manifold pressure driven wastegate ,cheers
RE: c250 om605 200+bhp. 6mm element - mantahead - 05-12-2013
hi Yorkshire1,
it isn't great in lower revs but once it spools it pulls like a train through all the gears.
more rpm would be good.
yea, pressure wastegate from 7.5 ton MAN.
turbo size beside original.

yeah, Im trying to get common rail like acceleration at the lower end may have to go with variable vane perhaps , nice welding on that metalwork by the way ,when you welded that exhaust manifold up did you have to heat it up first or is it just maleable cast, I just feel something can be done about the lower end dead area cos its a real killer. itd be nice to hang onto 4th and 5th more without giving 3rd a hammering on inclines corners

RE: c250 om605 200+bhp. 6mm element - mantahead - 05-15-2013
got the timing sorted, not much more power but lower exhaust temperatures.(650c)
maybe try a remap and get the revs up a bit and see what happens.
here is graph.

how much boost do you have ? whats beckpresure ? with 6mm elements modified mechanical pump i'm geting ~150cc of fuel
RE: c250 om605 200+bhp. 6mm element - mantahead - 05-16-2013
hi, boost is 1.5 bar, no backpressure gauge, potentiometer not giving so much fuel, i think a remap will help.
you must have modified delivery valves to get 150cc. what is your EGTS?
RE: c250 om605 200+bhp. 6mm element - mantahead - 05-16-2013
shortened the intercooler pipes and removed that pipe that the turbo was heating up. made a new pipe out of aluminium, and onto stainless bend and 90 degree silicone.
not much room for clearance with bonnet and washer bottle.

cheers,
think its garrett, some are kkk.
some guys use them as an upgrade 306 peugeot. Think its because of the 3 bolt flange.
RE: c250 om605 200+bhp. 6mm element - anto - 05-17-2013
Is it a t25?
A few lads i know have the kkk off the 300. If you ream out the hotside of the 306 kkk itl slot right in.
Very easy upgrade but they arent easy to find!
If you have any lying around let me know...
Any thoughts on making that an mtdi? Do away with the electrics?

mtdi?? mechanical pump?
would like to, dont know if auto box will be happy.
RE: c250 om605 200+bhp. 6mm element - anto - 05-17-2013
Yeah mechanical pump.
Although they dont control the smoke as well as an electrically controlled pump i far rather prefer mech for its simplicity. No sensors to go wrong etc and with regards smoke control, thats what the right foot is for.

From what I've seen C250s have a Garrett GT25C fitted and E300's have KKK K14 turbos with the same 3 bolt flange.

I'm literally about to buy a 250td estate with 722.6 to superturbodiesel, can I ask how you fooled the ecu when you switched to mechanical pump?
Retained the rack potentiometer from the electronic pump and connected it to mech linkeage? Or does the ecu just work with it disconnected?
Any info mucky obliged!

How do you install the potentiometer to controll rate of injection? I am researching how to raise
fueling on my 606 and I didnt find anything so far about using potentiometer.
Would you be so kind to provide some info describing it. I bet few of us could use it on DD.

i changed the waterpump on my 603 last week and i had to remove the timing marker to get to the last bolt, maybe they didn't put it back with you when the have changed the waterpump
RE: c250 om605 200+bhp. 6mm element - Hario' - 03-22-2014
Yeah my E300 had a timing pointer I had to remove to replace water pump.
Probably dodgy garages not replacing it after water pump replacement.

Hi,
I've got a question.
You tested a straight pipe above the turbo between intake manifold and original plastic pressure-out from the intercooler and also the self welded pipe from above (that one next to the water tank). Was there any improvement with your self-welded pipe? I have also thought about both options you've mentioned, that's why i'm asking.
How was the improvement on removing the AGR inlet and replacing against the straight pipe?
greets
Ecto
