Welcome to the boards! Feel free to ask questions!
Quarter Mile for the VI is 13 flat.
I don't know VII's but supposedly it is the same or faster.
The 280 ps hp limit is called the Gentleman's agreement. Japanese manufacturers don't build cars that have horsepower over that amount. HOWEVER!! Many of the cars really do have more horses than that, but manufactures still say 280. For instance, Skyline and Lancer. Both of these cars produce well into the 300's. Hope that helps!
