now, you should search this topic first.. i believe we have 75 threads with the exact same subject allready.... by the way i have hit 4000Mph, quite easily doing the wheelie trick
my gt3 is in kph n it hit 1500kph (900mph), theres not enough track to go any faster!
if anyone knows how 2 make it go anyfaster on the test circuit or if anyone knows how change the speedo to mph email me on Polish_guy56@hotmail.com
