Question about gearing for Top Speed

I guarantee it. I have driven 60-90hp/200 ft-lbs torque engines 130.


i had to look it up, i took a 59 HP, 76 Ft/lbs kadett up to 120...but that was pushing it

there have got to be other factors then gearing and HP that come into play though, like the rolling resistance, or air resistance

Like the powertrain combo that GM put into the early 2000s pick-ups that hunted up and down at ~60 mph into and out of lock-up.

exactly
but it wouldnt surprise me if that was an MPG driven ECU micromanaging things
