If you use the calaulator I'm posting, for every 60 mph you would add 2 mph to your speedometer reading, so when my speedometer reads 180 mph I'm actually doing 186 mph (tach was at 5,600 to 5,700). With my RENNtech kit my redline was raised to 6,200 RPM, so I think 200 mph is obtainable in my car. To bad I don't have a brother or best friend driving a state cop car with a radar, I would rather be clocked with a radar so I would know the speed without question. HEY bikecop .
