Does anyone know what the max rpm is supposed to be on an XF 1100 non-turbo. I was thinking it was around 8300rpm. I went for a drive the other day and hit the tell-tale max rpm on the guage it showed 8900 rpm! I never had it past 3/4 throttle. I know my 4s phazer would rev 12'000rpm but I was sure these aren't made to rev that hi.
