you have plenty of boost mods over a stock 1M!... Yes.. Mike knows the track.. is a decently good driver...
At COTA.. if a driver is able tostay relatively close (not an easy feat, especially in the essses ) but once you hit a medium sized straight or particularly the back straight... the 911s walk away.... Exactly as Pete mentioned... the 1M runs out of breath a bit (still easily reaching 150mph) where as the RS is probably touching 165 mph at the end of the straight.
