I changed the secondary pump to the primary, noise gone and rail pressure was higher. Still holds pressure on song.
Either way, two new 044's are gonna be put in. Fuel is not something I wanna f**k around with.
And not holding pressure. You can see the pressure dropping off until the secondary feed comes into play at a certain duty cycle. The noise it's making is strange. Not there all the time.Anyone else had issues with 044's? I haven't heard of any???!!?
One bank of 3 cylinders feeding one turbo with no funky valving. Same same on a straight 6 like the RB26. On either engine there is no "staged turbo" arrangement.
