Is there such a thing as a turbo'd ZX14 that can't be heard from miles away? What about maintaining the civilized nature of bike?

Romans claims to have one that all you hear is the turbine.

Does the power only kick in above a certain rpm?

I'm sorry. I was staring at your avatar...What was the question again?

2nd that.

Yes a turbo bike can be quiet. My bikes are very civilized street bikes. Without giving the bike a close inspection no way to tell she is boosted

My turbo is loud upon startup, then seems to quiet down when warmed up. On the highway the wind noise is more noticeable.
I've thought about a muffler, but use earplugs for now.

Can you feel the turbo at all RPM or just above a certain amount?

Where my system gets noticeable stronger is at 4lbs of boost which is when
Methanol gets activated, but as long as turbo spins its making gains over stock.
I let off the throttle when front wheel comes up. Have no idea what happens after 7k rpm, but
You need to be extended to experience that.

Not the resident expert but from what I have heard, the lag is not noticeable with a bike because it is so light. Also, the weaker boost at low rpm probably makes an improvement for the same reason.
