What up grades can be made to a VED12

Now the D-12C race engine is revving up to 2800 rpm, more is possible but the owner is afraid of breaking it even if I try to convince him that over 3000 is still safe. Power is about 900 hp now, there's some parameters still limiting it but ECM specialist said it will be solved before next race, then there should be about 200 hp more. Engine is running smooth and nice without smoke, not like those crappy Cats popping jerking and chattering around.

 

And in goes the bait!

 

Any new news on the upping the Volvo engines HP?

 

Use D16 injectors, they have 1mm bigger plunger and stock 610 hp tips are good for 900 hp. Marine tips flow more of course.

This D16 sounds strange but seems to be very responsive http://www.youtube.com/watch?v=lD2uQvG8m8Q

 

Do I need to reprogram the ecm after doing so
