(06-17-2013, 07:35 AM)maKe- Now the pump competition is starting to get really interesting.

I wanna see the new 8mm pump with 7000-8000rpm gov and to be able to burn +200cc fuel at those rpms if it's even possible with IDI. Diesellandia Herlevi can configure their 8mm pumps with 8000rpm if wanted, but fuel at those rpms...? Mynä 8mm is proven 700whp with 86mm Holset single and Herlevi 8mm is ~600whp with 70mm Holset.

The new cam lobes will effectively increase plunger stroke and pressure before forcing fuel past delivery valve. In theory fuel quantity is increased but is the cam duration same as before and only lift increased? How is the injection advance/pump timing going to be different when using a cam like this?

A fixed timing is not optimal solution, but can mechanical pump ever have a timing suited for every rpm ranges from 1500-2000rpm cruise to 6000-7000rpm full power blast?

If Göran nails this new 8mm pump and +600whp is achievable without too much hassle on less than 70mm turbo (engine configuration spot on) and driveability is ok I need to hurry up and get my 606 soon.

Im really not up in any competiton against the Finns, No way! Little me against the Finns??
After I joined superturbodiesel.com and read alot of threads concerning the pumps I thought that something needs to be done.
Why not open up and show how to do it instead of just lock everybody out from the dieselworkshop?
That have been done and I have got so much good feedback on that.
GTG at the workshop, I suggest 5-6 hours, but after 8 they want moore, That tells me that there is a big intrest in this kind of work, and that really makes me happy.

Next thing, after working with pumps over 30 years, for me its no longer a work, its a passion, I love my job, Hell I even got a licens plate on my company car that says FUN2WRK.

These small M-seriepumps have been a new challange for me, Im testing different setups, different elements, deliveryvalves etc.
Now I think I have taken this to level 2 with the stroked camshaft.
Maybee its done before in a M-pump, I dont know, but I have never heard of it
How much fuel will I get this time? I dont know yet, maybee I have spendt 1500 USD on grinding 3 shaft with no result at all?
If so, whatever, I did at least give it a try.

Wire EDM on the lifters will be done this week, so if I have time for it, first bench test will be made soon.

I can tell you that these tests that I have done, have cost some money, but what I earn on the superpumps, goes back to the superpumps

I will keep you all that read this thread updated and when I´m ready with the pump a recepie will be public. You of all are going to have it first.
