hm... rx7 can do, well has done 1/4 mile in 7.33 seconds. A 650hp honda civic where I am from has done 1/4 mile in 11.5 but its 1600cc. a mitsubishi EVO stock can do 402 meters in under 13, you can fix it to do under 9 eisily. The point is, that americans need 8000cc to make a V10 engine, add two turbos to make 800hp (viper). where as the japanese added 850 hp onto an inline-6 engine (this nissan), there will never be an american 6 cilinder egine that will be able to handle 850hp. American cars cannot compete with japanese, and compared to european cars, well Ken Duttweiler Buick Grand National 4.5 liter ( 274 c.i.d )V6 twin turbo 1500 horsepower and runs the 1/4 mile in 7.20@180 mph and yes i have seen many many American V-6 engines making well over a 1000 horsepower . Oldsmobile Aerotech quad 4 , 4 cylinder 2.0 liter made over 1000 horsepower,so we can build small motors with high horsepower and big ones with even more.
