My Superformance GT40 has a throttle body injected Roush 511 cubic inch all-aluminum big-block Ford V8 (that's 8.4 liters, if you're thinking along in metric) mounted amidship. The front of the engine is about 8" behind your ear, separated from the passenger compartment by only a thin aluminum bulkhead and a piece of Plexiglass. Loud as fuck, to put it mildly. Naturally aspirated with 8 individual stacks and intake runners. The intake howl is something to behold. Mechanical throttle linkage - no drive-by-wire - so the throttle response is immediate, almost psychic.

And after about 45 minutes or so, you're ready to park it and put a bag of ice over your head.
