Speed at Redline in Fifth Gear?
Has anyone under safe conditions approached redline in fifth gear in a base Boxster with 5-speed manual transmission? A recent dyno run got me thinking about actual top speed of our cars. Are the 2.7L cars limited by gearing and redline limiter or power available in order to be able to reach maximum speed in fifth gear.
At 7K redline I am going about 103 mph in third gear. I have never driven to the redline in fourth gear on the road, but on the dyno, the limiter cuts in just over 7K at 138 mph.
Any thoughts about gearing and power of the 2.7L engine pushing toward redline in fifth gear. I would sure like to find a track, salt flat or someplace to see where the cross-sectional profile and wind resistance of our cars runs into the power output and rpm limiter at our top speed.
