7,5 mm Element design for high performance engine
7,5 mm Element design for high performance engine
As some of you here on the STD forum knows, I have been struggling with making my own pumpelement for the M-seriepump. I want to reveal some facts what I have done the last year.
Previously I have done pumps with the "old" 7 mm Ford Transit element, Also with the 6 mm original OM606 element. My opinion was that the 7 mm didnt work out well at all, High knock at low idle, high fuelconsumption max 120cc was some of the disadvantages with those.
6 mm was running perfect, good balance nice idle and so on.
After those pumps my customers wanted moore fuel, Myna was running 170cc with there own 7 mm element, However I could not buy those, Myna dont sell element only, they just put them in there own pumps. The explanation I got was that
-It is some difference in quality.
At this moment I have around 10-15 pumps waiting for nice, big element whit a lot of fuel.
Something had to bee done
I started do design the first serie of 7,5 mm element, It took around 3 months for the factory to make them for me.
At this moment I have payed around 8000 euro.
After 4 months the goods arriwed, I was glad for about 4,5 minute, then everything went to ****.
Barrel was too big, didnt even fit in the pumphousing, plunger was 0,15mm to long, The plunger could not go to top in the pump, it was stuck.
This however I could fix, my friend, who has a mechanical workshop helped me.
Barrels was grinded down to right dimensions so that they fitted in the housing, plunger was modified so that I could mount them in the pump.
First pump was 2,5 degrees wrong in phasing, That was no big deal, but it gave me a lot of extra work, changing rollers in the tappet lifter so the balance was OK.
Next thing was fuelquantity, I was expecting a bit over 170cc but no.
140-150 cc was max at 21mm of rack BUT, It had capacity for OVER 200cc
The "only" thing was that the helixangel on the element was to flat, I would need around 25-26 mm of rack to get 100% out of the element.
80 elements where adjusted, 10pc of 140cc pumps was built with good result. I bougt a 250TD with OM605 just for testing the pumpelements properly.
Rest of the elements where shipped back to the factory for modification.
Serie 2 was up on drawingtable, wise from the first serie I know now how it should bee designed, Serie 2 has som benefits that serie 1 dont have.
Here is a small teaser
50 days from today and serie 2 will arriwe for testing. After that gentlemen, I think that I can offer you some nice pumps.
140cc & a bit moore.

Thanks for all of your hard work! And for posting on this forum. I'm excited to see how this works out I'll have to start saving up for a custom pump!
Schttttoked!

No need such thing as 20-21 mm track travel

Ofcourse you did. You get a element that works in the first place, You can buy element from Tom, How hard can it bee then? You dont design, you just build the pump.
Toms element is nice if you dont need moore fuel that 140-.150cc, My customers building high performance engine, just as the topic says, and then Toms element is not enough
Im trying to explain how difficult this is, I dont need any devaluation.
I think this is going to workout perfect, just you wait and see.
Some people has not been so helpful to me, that is one of the reasons I had to do something.

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
I like the sounds of 200cc

Göran, Thanks many times over for posting your thoughts, expertise and videos on injection pump building. Folks like myself love to see these journeys in type of build in action and explained.
I hope all the success in this one and perhaps maybe later, you can design and manufacture an affordable higher output MW element.
.
Interesting and very effective looking helix design. I am glad someone is making an element that gives more fuel than ~150ccm, as why go through all the trouble and expense with changing the elements only to find you need more fuel. <150ccm elements have there place as well.
Thanks for posting this, and keep up with the great, and sometimes discouraging work!
great news goran ! do you keep the standard turbo ? is it able to cope with the extra fuel delivery..?
keep us posted goran......

If I had an M-pump I would buy these elements in a second!!
I have a M-pump that needs to be modified. Who do I need to talk to?

Hi Göran,
the interest was in having a US guy do the pump...
Tom
I don’t want a US guy touching my pump. I don’t want to be a lab rat. I want a pro. So offshore it will go.

Gøran`s 7.5mm elements killed my 2nd and 3rd gear! But there is still brutal acceleration in 4th So I am very pleased with the pump and the job Gøran did! Gøran is the man
Yes, I know that my serie 1 element works out well, it just needs some more love and care when putting them into the pump.
Nothing for do it yorself.
Serie 1 will never bee sold as part only, I only put them in by myself.
Serie 2 however will be on the market, But only after testing them out.
I am glad that EDH_performance i happy with his dm superpump.

Glad I didn't send my pump out yet...
By the way, where are the dieselmeken stickers?!
I need to find another job pronto so I can afford this lol
Here is one

The other car is an BMW 325ix with 170 hp.
I have no 3rd and so I have alot of lag I 4th because of that
Feeding pressure to the pump is 3bar.
The turbo is putting out 1.7bar, around 450-500c in EGT, and it is still smoking, so i need to turn the stoparm down a bit more
