More from Enginelabs, to fair to them for a site mostly tied to US hotrodding they cover a lot of modern hi tech designs - far more tech data than Autocar, Evo, etc combined can manage.

 

This is a new Maserati twin turbo engine, it has pre igntion chambers and , something new, an ECU controlled dry sump pump.

As t

eehy say the technical drawings are very detailed for today but my old fashioned brain tells me not to trust an ECU to pump oil ?

How does the ECU affect the scavenge pumps which are, in usual style, look clearly directly crankshaft-driven? I wonder if the crankcases are segmented as they are in F1, you must get a nice strong pressure pulse from the crankcase timed to crankshaft rotation and in F1 it is normal to vent the crankcase breather into the airbox to "prevent oil loss to the track" through the breather. Hard to imagine those breather ports don't affect the intake wave dynamics.
