Well I got 655 mph out of one of my subarus. It is the pleo with the 7 speed. It does this wierd shit at about 540 mph it all of a sudden moves backwards then accelerates through 655 and then hits the wall and I lose it...lol It has 16000 hp with 1700lbs. It is absolutely the most uncontrollable car i have driven under throttle. It has friggin traction problems through 350 mph. ITs pretty friggin funny. If any of yall need gameshark help shoot me a pm and Ill tell ya how I got it to work easily or if you got any cool shit too lemme know. Thanks tony
