Ask experts for answers. What's on the STR-8 engine of Dodge Challenger in The Fast and the Furious?

It is equivalent to a gas collecting box. The throttle valve directly faces the windward side, which increases the air intake and has mechanical pressurization. See that belt? That's a turboprop. It's driven by a belt. I don't know what it's called as a whole, just throttle valve, gas collecting box and supercharger. A combined device of intake manifold! Very impressive! The upper three holes are throttle bodies. Generally, engines with less than ten cylinders have only one throttle body, and this one has three!
