They say it is useful for an uprated 4 cilinder supercharged Ecotec, which makes sense...
On a boosted motor, the difference made by a big TB is even less important 🙂
Supercharged Eco's tend to have the throttlebody before the SC, and then it makes sense to lower inlet restrictions when you approach the 300HP mark. Turbocharged engines normally has the TB after the Turbo/intercooler, so running with denser air. Than this sucker is totally overkill. 8)
While we speak of superchargers:
In the US it is said that the 2.0SC inlet manifold with the laminova cores is not flowing that well... This causes the SC to run out of efficiency range at higher boost pressures/rpm's. Seems there is quite a difference in pressure before (= SC pressure) and after the intercoolers (= boost reading engine).
If we think that a well breathing 2,2 makes close to 180HP with some mods, running the same engine (without flow restrictions and good inlet temps) with 1 bar overpressure should theoretically double the Hp... (Besides that the rods will come out ) :lol:
