deug: Do you have times for the N1? As far as I know, the Skyline there wasnÂt dyno tested. 280 hp is the gentlemenÂs agreement (horsepower cap) they have in Japan. ThereÂs a good chance it was quite a bit more than 280 hp. Nevertheless, TopGear tested a Skyline GTR V-Spec rated at 350 hp for their 10/97 issue. The best it could do was an 8:37. A 339-hp Corvette tested in the same session, equipped with an automatic, was only 8 seconds slower. A 321-hp BMW E36 M3 was one second faster than the Skyline. Best time of the day, though, went to a Ferrari F355, which clocked an 8:31. I have no doubt that a current-spec 460-hp US Viper GTS ACR w/ABS would smoke them all. Special order the ACR Plus with 506-hp and standard adjustable coilovers properly dialed in for the track, and you may see lap times drop even further.
