Supercharger uygulamalarında kelebeği hep emme portuna takıyorlar. Oysa turboda kompresyon tarafında kalıyor. Bunun nedenini bilen varmı? Sonuçta ikisinde de recirculation valve var.
MB için SC kiti üreten bir şirketin sayfasında şöyle bir açıklama okudum. Ama aynı sakıncalar sonuçta turbo içinde geçerli.
"THROTTLE PLACEMENT
As with the Roots-type supercharger, you must install a bypass valve and relocate the throttle body ahead of the supercharger's inlet port when implementing a twin-screw supercharger. If you don't move the throttle body, the pressure between the supercharger and the throttle plate will build up on idle, or when decelerating or changing gear. When the pressure between the supercharger and the closed throttle exceeds the boost pressure produced by the supercharger, the air will be forced back through the supercharger. This will cause the supercharger to cease as air can only move in one direction through a positive-displacement supercharger. As a result, the drive belt could be destroyed and the throttle plate could buckle and get jammed in the throttle bore as the pressure will not be released. However, relocating the throttle body will result in poor throttle response but this is unavoidable.
