Any turbo guys on here that i can ask a few questions?

Turbo threshold, what is that?

Spool, when someone asked at what RPM does a turbo spool. Is this when the turbo starts making power?

Questions might be dumb to most of you but i just need to learn some more.

I haven't used the phrase Turbo threshold before, but I would describe 'spool' as the revs at which the boost curve starts to climb noticeably.

I believe turbo threshold, boost threshold, turbo spool, spool-up, etc, all mean the same thing, as griblands described.

If you want to learn all about turbo's:
