Just guessing on this one, but it COULD be that the thermostat won't open completely. At an idle, the coolant circulates enough to cool the engine but when the engine is producing more heat, like when it's running at 60mph, it overheats. Just a guess, but I'd start there. The thermostat is near the front of the engine, on top of the intake manifold. It's under the upper radiator hose. Pull the radiator hose connector housing and replace the thermostat.
167.371776 Km/h Ill tell you a cool trick go to google.com and type "104 mph to kph" and it will tell you so you can use it again.
To calculate speed, you need to know the time taken to cover the distance. If you provide the time taken (in hours), we can help you calculate the speed. Speed is typically measured in kilometers per hour.
To perform a drive cycle for a 1999 Mercedes SLK230, start by ensuring the vehicle is in good running condition with all monitors reset. Begin with a cold engine, letting it idle for a few minutes, then drive at a steady speed between 25-45 mph for about 5-10 minutes. Follow this by accelerating to 55-60 mph and maintaining that speed for a few minutes before decelerating without braking. Finally, come to a complete stop and allow the engine to idle for a short time to complete the cycle.
165 mph = 265.54 kph (rounded)
99 kph = 61.51 mph
10 lbs. of oil pressure at an idle is not uncommon for a 350 if the idle is low . what does it do at 30 mph. or more ? that is where you should be concerned. if the pressure is around 40-50 lbs. at 50 mph. it's ok.
Sounds like preignition. A higher octane gas might help
350 km/hr is equal to 217.48 mph.
