This will be my first time going to the track. I have a 98 Cobra Convertible, with a K+N aircharger, and welded Flowmasters. That is all I know of as I have only had the car for 2 weeks. My speedometer reads about 9MPH faster that I going, but I still do not think it has gears(Any tips on how to find out?). Can anyone tell me what I should expect assuming stock gears, and also give me any tips for the track? Thanks!
