Even a stock turbo can break 200mph with slight tailwind and downhill. A 550bhp tuned turbo can easily break 200mph.

I've run over 202mph and a friend over 205mph GPS verified within 1.3 miles airstrip. Pretty sure we'd hit 210-212mph if we had 2 miles.
Agree that the numbers don't look right, I can hit 100 in 3rd and 130 in 4th.

Looks like the Porsche PDFs I pulled this off of switched 3rd and 4th gear ratios?

Here's the updated deal, still got to spin it to 7000 rpm to get to 201 mph? Unless the PDF has incorrect ratios, or you have bigger tires than the 305/30/19 26.2 tall? Please let me know what I have missed?

That's the difference, the gt2 has different final drive at 3.44 and a 6th at .73. Other gears are also different, but the top speed is 217 at 7000 mathematically. You must have this transmission and rear gear.

Well , you definately don't have the gearbox and rear gears in the file above.
