Redline on the typeS is 7900 but the rev limiter doesn't kick in until 8200/8300. If the car isn't warmed up enough the ECU won't let the revs get into the VTEC range at 5800 RPM. Sounds like you may have hit the limiter, and that doesn't do anything but shut the fuel supply down to drop the revs. But when you take it in to service it, the ECU will tattle on you to the mechanics if they do any computer diagnostics.
