On the Injection pump is device which one call ALDA.
Injection pump for normal aspirated engine - ALDA looks little different - small tube is open to the atmosphere - is working like a barometer.
Turbo - have connected house from intake manifold - sensing the pressure -
when pressure is rising up increase fuel delivery.
More pressure - more fuel.
This is no problem to control turbo.
Thank you for the link to supper guys - expellant job - I get lot of new ideas.
On the weekend I tray to use translation on the line - I see some of them just need inter the net address and do conversion.

...I'm familiar with the functions of the ALDA and ADA (NA). What I'd like to know is how they found a way to increase the fuel load to accomodate the increased boost AND reduce that fuel load when boost isn't present. The ALDA's primary function when boost isn't present is to retard the fuel rack within the IP, reducing fuel, then gradually allow the rack to advance (increase fuel) once boost pressure rises. Absent this retarding effect, the engine should theoretically smoke tremendously at idle and when boost isn't present (too much fuel). This isn't very efficient and could lead to coking within the prechambers and injector nozzles. I've noticed the Finns have used non-ALDA IPs on several of their Super Turbo projects, so there seems to be some question as to how they've modulated boost enrichment with these pumps.

On Idle lower rev we cant see smoke - more fuel higher speed.
On the heavy load - acceleration we can see smoke - to much fuel engine cant
burned.
