I got new pump from Dieselmeken, 8,0mm 220cc. Today was dyno day and I made 377kw/505hp/799nm from wheels. Don't know why but boost was only 3.2 bar, there was enough fuel but something was wrong with wastegate or maybe it really finally needs stiffer valve springs. Last year I made 433hp with HX40 and also 3.2 bar, now a lot bigger turbo and only 70hp more.
Engine is NEVER OPENED and ALL STOCK, no new internal parts and donor had 470k km. Only engine mod is 152bar injectors and nozzles are also stock. Now need to sort it out what is the cause of why it's not going over 3.2 bar.
RPM is a little less on sheet than actual because rpm signal was taken from PAS pump wheel.
