I have been reading about the "perfecting" of turbos recently. The near elimination of turbo lag allowing for power to show up lower in the RPM band. I even think they are showing up on some drag cars now with sounds as if they are going to be permanent.
The Squires system showed up here a few weeks ago and that's what got me to studying the subject. The Squires remote mount system reduces the heat issue and they can run smaller impellers which provides the boost earlier. In effect charging the the intake pipe even at idle but with electronic control allowing for fingertip control of the overall amount of boost.
It seems like with the turbos, they have overall created induction that can create tremendous more boost but keep it in check by using wastegates and electronic control. So, they have smaller impellers creating boost at a lower RPM and then able to control the top end of that boost using the wastegate/electronic control.
I am no expert, engineer, owner, tuner, etc but this stuff like this always intrigues me.
