Its Always been a sorta 'Closed-Shop' almost Secretive. You could go into any Injection-shop in UK and ask what rack-travel you'll need for a Standard pump versus delivery--And they'll look at you like scum!

Ive made pretty good friends with a local guy and its taken years to build up a friendship to the point he'll tell me all he knows.--Which is nice!

The FIE (Fuel Injection Equipment Makers) guard all pump details like you wouldnt believe! It goes down the chain to the Appointed Dealers (Bosch, Stanadyne Lucas et-al) these dealers are threatened with loss of the dealership if propriety info is 'leaked out'. Those who work for them may go on to open their own places, not appointed-dealers, but the same 'ethos' has been instilled into them over the years,--so they just Dont Talk about it, or impart any info.....

Goran and Tomnik are great enthusiasts. Goran has his own Injection-shop and all the equipment you would ever need. Tuning of IP's isnt his 'core' business I'm guessing--He does that because he loves it!

He shares his knowledge happily with the world as does Tomnik, This in my mind makes these guys really special and a cut above the 'closed-shops' such as Myna....
I don´t think you have spoken with mynä, they say everything you want to know, but i would guess that they don´t share secrets of how they gets the juice out of the pump, but do I need to know that? I have no winning in knowing how they make their pumps, i just wanna know "how to use it" so to say. to tell your own little secrets you have to get more cc from the pump isn´t to clever because if outher copy your things and do it for less money they steal costumers and you loose money

Thanks Alistar for those words, You are 100% correct, these tuned pumps is not the base in my workshop, Its the regular Deplhi, Bosch, Stanadyne, Denso, Zexel pumps, Inline & distributor pumps. The last 5 years the commonrailinjectors has been a common product to work with. I have so I can repair & test Bosch & Delphi CRI & CRIN, light & Heavy duty.
Tuning pump is about 5% of my turnover for a year, but its a challange everytime, I challange I like.
For me, after 35 years with dieselfuelinjectionpumps, mounting & timing a pump on a 1000hp V12 engine is no longer a challange, I know that it works

To design a 7,5 mm element that works, That is a challange and I gladley share it with those who have intrest in it. That is what this topic is about.
If you dont care, this is not the right forum for you, here on STD the intrest is a lot bigger around the work I do than in many forums in Scandinavia.
Regarding the "secrets" Mynä and other tuners have, I dont need them. I know how a pump works and I know what to do to make it work, Its all about having the right stuff to put in the pump, and how to get the stuff to work.
One question is, do the customer that write & phone me know how much fuel the really need? Answer is NO.
They have heard that mynä has 170cc, 8mm, 200cc+ etc and they want that althoug they cant burn it.
To burn that amount of fuel you need to build an engine EDH performance & Jeemu style, not many people that can manage that, its not enougt to just change pump & turbo to get 450-550hp even though most of people seems to think so.

A question to you all, do you know approximatly how many engine degrees it takes to push in 110 ccm of fuel from a 6 mm element at full rack(19mm)??
This is from when the element close the inlet port until injection stop, when port is open again.

Leave a guess.
