Heres a very cool and detailed tech article from motoiq.com.

Some selected quotes

If you do a google search on these cars, you will not find much information on them because until now, no one that cares has gotten a really close look at these amazing machines.

The team's engineers were very quiet when we asked them about the engines specs and we were not allowed within 20 feet of the engines or any internal components.

The engine is forced to breathe through two tiny 29.4mm restrictors by homologation rules. This is the main reason for the low sounding power numbers. Since the airflow to the engine is limited, the engine is redlined at a relatively low 8,600 rpm as there is simply not enough breathing to efficiently rev higher.

The engine's exhaust exits into 4-1 headers with a crossover pipe just past the down tubes. The exhaust is sunk into the floor for better aerodynamics and fits into a double wall oval section directly under the car. A unique feature is the double wall exhaust and heat chimney.

The article say's the engine can't be moved back behind the stock firewall, but it sure looks like it's WAY back.

They're inside those large ducts up front.

The engine compartment air management is amazing. Everything is done to increase downforce and minimize drag. The air from the lower part of the grill opening is fed by streamlined ducts through the engine coolant heat exchangers then out the top of the hood.

You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
