S4 turbo opposed to s5 turbo
I'm curious how the s5 turbo is better then the s4 turbo? I don't mean the engines. I have searched, but i've been searching for probly a good 2 hours and still can't get any solid information. All I got so far is the wastegate is more efficient and the hot side is more efficient. Or did I just nail all the benefits?

The center portion and compressor side are identical to the S4's. I believe the compressor wheel is different, as well. The inlets for the turbine side are larger as well. The S4's had the twin scroll system, and one of the inlets was a tad smaller. The S5 didn't have twin scroll, and both inlets are the same. The S5 turbine side is considerably larger than the S4's as well.
I do hear tell that the S5 is more reliable when it comes to keeping boost spikes down.
