True, but can they build the same boost at low RPMs as a turbo? Coming from the individual throttle S14, S50Euro, and S38 world, turbo lag was a new thing for me. Fortunately the tiny little coffee cake roll sized turbos we have are rather fast at our pressures. Does the S4 blower make significant boost at, say, 3000-3500RPM? Or is it better to just start higher up, maybe 5000-6000? Just curious...
