Against a new M4 at that. I have PPK1 and an alpina flash, M4 was stock. My best time(the one I didn't royally fuck up, only a little lol) was a 14.3 at 97 mph. M4 hit 12.7 at 116 mph. I'll try again sometime, I have to figure out the brake boost before the full stage, it's pretty rushed.
And to put rumors in the ground, a 2012 Evo 10 with COBBAP and perrin exhaust still did a 14.3 at his best time, STi same mods did a 15.1 but he couldn't drive worth shit.
Also raced a 92 Evo 1 and his best time was 14.9.
