om 606 + holset hx 40 + which IP for minimum smoke?
om 606 + holset hx 40 + which IP for minimum smoke?
with the best whishes for a happy and peaceful 2016 I am interested in your experience.
I am in the middle of my std-project. 90% is mounted. But: whith the first start, my om 606
ran away due to my 7mm-pump stuck fully open … - engine seems to have survived the three minutes at est. 6000rpm cold ...
Now I am driving the old series pump turned open to the max ….
As I now have to open and dismantle the stuck 7mm-pump I am thinking of putting in bigger elements for cleaner combustion … (100cc … don´t know) …
Some folks say, bigger elements - shorter injection time for same volume - cleaner combustion (which was my goal together which 350 - 400 hp …)
What is your opinion?
cheers

Thx for reply… - but
still: which Ip do y´all recommend together with holset hx 40?
Thinking of 8 or 8,5 mm elements … short injection time - 12 degrees past … . 2,0 - 2,3 boost - depends on egt … -
on the other hand…
the bigger the elements, the beastier to drive?
What do you think?
Best regards
Ahm - because I wanted the hx 40?

. From the boost you are planning to run, efficiency of intercooler, volumetric efficiency, target afr and target rpm you geta fuel level per injector per 1000 injections.
My understanding of your motor and desired power level suggests you do not need 8mm elements. But all 7mm elements are not created equal.

Well, any high power setup with HX40 would probably always produce some smoke IMO... I would guess getting an 8mm pump. Since a lot of folks on here get their pump from Dieselmeken (including me) why not get one of those? Or talk to the guy. He's the expert. He may recommend you a 7mm pump. To my knowledge the 8mm is a little rougher on idle. And all dieselmeken pumps are fully controllable by the user by turning some extern screws. So you could always go down in fuel
Herlevi, myna and dieselmeken all make pumps. Myna has been considered best by all Fins I have asked. But they are also most expensive. Plenty of herlevi and dieselmeken Videos on YouTube also showing good results and happy customers. Ppd also make pumps but maybe not 8mm.
Best approach is to email each company and ask what they recommend for your situation. I think it makes most sense to begin with with a power level then select fuel level for pump then select turbo. But if you already have a turbo then you can work back to fuel level.
