lol i told myself i wasnt going to get into this one. but i find it hard to believe you know anyone with a 4 cylinder mustang that will dust an srt-4. and i'm calling total bs on you knowing more than one person with a 4 banger stang that will smoke one. 4 cylinder stangs are SLOW. they can be made fast with enough cash, same as any other car, but you'd have to put like 10-15k into one to break 12's. for 5k you could swap in a massaged 5.0 or 347 stroker, which is what people do to make fast mustangs, unless they're idiots.while i dont much car for sport compacts, i respect anything thats fast. my trans am runs 12.6's without the nitrous and on street tires, i ran an srt-4 running 20psi of boost, a stage 2 turbo, an upgraded intercooler, a custom chip, headers and a few other odds and ends. basically, i destroyed him off the line, pulled almost 2 car lengths, but by the end of the 1/4 he had almost caught me, his nose was right at my rear bumper. i think he said he put 3 or 4k into his car after he bought it. not bad, even though i only paid 6k for my gta, i had to put another 8k into the engine, transmission, and rear to make it what it is.
and honestly, a stock srt-4 with a REALLY good driver will take a stock ls1 with a REALLY bad driver (although the ls1 will sound, feel, and look a hell of a lot cooler)
an 11 second srt-4 (although im also calling bs on that and dudes 460 hp claim unless i see some proof) will decimate an ls1 even if john force himself is driving.
EDIT: i didnt spray it when i raced dude or it wouldnt have even been a race
