What do you guys think the max safe cruising speed is on the supra? Assuming no traffic 4 lane highway like say driving from flagstaff to Albuquerque. I don't mean safe like not crash and die but safe for the drivetrain. I don't imagine that it engine would be happy cruising 5000 rpm and probably a couple pounds of boost for hours at a time. That's a lot of wear. I'd say 120 is probably the upper limit due to gearing. What you guys think?
