I'm waiting for one of these boost guys to use a ball bearing liquid cooled variable vane turbo. If you don't know about variable vane technology... You can, theoretically, used a much larger turbo because at low engine speeds the vanes close making it a smaller turbo and giving way better throttle response. As you get into it the vanes open allowing much less restriction on exhaust and more boost. You can control the electronics via computer to have it all. No lag. Responsive as a jet. And sounds like one as well
