My friend has an 05 V6 5spd mustang that's 100% stock, it's always been a good race between his 05 and my 82(with the mods in my sig), somehow my timing was 22* off for about the last 8 months...and he barely beat me starting at about 40mph, Since i fixed the timing (12*BTDC now) i can pass him when we start at 40mph on the highway, i dont pull away hard but enough to get a car length in about 3-4 seconds, starting in 3rd..we are both competent drivers and know how to drive our cars, we both push the cars as hard as possible so it stays pretty consistent, keep in mine i am still on the original 82' motor and stock heads(never been apart), your newer car should take him by a few lengths, starting at a stop will kill that V6 by at least 5-10 car length in 1/4 mile, good luck and go practice your shifting
