Lmao not to mention a Triumph GT6 is a 2100lb car with a whopping 95hp...aka, significantly less horsepower than a 600cc Kawasaki sportsbike in a car. According to wiki its top speed is 106mph, which is slower than such modern race cars as the Kia Rio, Honda Fit, Toyota Prius, and even loses to new microwave sized 3cyl in the 1.0l Civic.LOL come on man,you did NOT go anywhere near 300 mph in a gt6+ nor has anyone for that matter,not to mention that still today we don't have tires capable of this! Today's highest speed rated tires thanks to the autobahn and real world testing is only 186 mph and at 300 mph todays tire has a life span of around 4 min at best and the older tires would have blown apart long before that!
There is a way for him to go 300mph. Simply by standing still, we are all going at like 600mph due to the earths rotation and many thousands of mph if we observe the galaxies rotation. He is technically telling the truth, it all depends on the inertial reference frame of the observer....I've only gotten around 31mph with a stock engine, and i did 40 with some performance mods. Only real pros know how to mod these engines to go 300mph.
