I think the translation is throwing you off - what's coming through as "surge tank" is actually referring to the intake manifold. Part of the design of an intake manifold is to serve as an "intake air surge tank" to try and even out the distribution of intake air to each runner. The section that does this is also sometimes referred to as a plenum, and the Wikipedia page for "plenum chamber" actually has a really good definition of what this does:
"A plenum chamber is a pressurised housing containing a fluid (typically air) at positive pressure. One of its functions is to equalise pressure for more even distribution, compensating for irregular supply or demand."
The article indicates that the car made more power with the FA24's manifold and throttle body on vs. the FA20 red manifold and throttle body.
