What happens here

Boyd Butler, known as Dr. Gas, introduces his 1965 Mustang race car, 'The Sledgehammer.' He details the engine's specifications, highlighting the individual throttle bodies (ITBs). He explains that the ITBs prevent exhaust gas contamination in the intake stream, which often causes a 'rough idle' in engines with high-overlap camshafts and carburetors. This system results in superior throttle response across all RPMs.

Goal: Introduce the custom race car and explain the function of individual throttle bodies.

In a car that has an intake manifold. Actually, if you want, I can 100% answer this question. Oh, actually,
