I refer to Alfa product bullettin PA381500000000 Jan 86 for Spider 115. USA Version Graduate, Veloce, Quadrifoglio. This is on page 36 (RPM vs Road Speed Graps for gears 1 thru 5)
Fifth gear, 100km/h, 2800rpm
Fourth gear, 100km/h, 3500rpm
My 87 Quad confirms these points.
I would take it that your 92 would follow the same curves, as such you are going faster than your spedo indicates.
From the same curve I reference 3500rpm in 5th gear is 130km/h
Best regards, Elio
