i dont doubt there is a few people who have done it, but thier are several dsm's who have done it, i mean a shit load, just like a 1500 302 ,T5, instal exhaust and slicks and you have a 13.9 easily

its easy to get high displacement/turbo cars a full second or 2 faster than stock times with simple, simple mods, due to restrictions from factory(damn enviremental hippies)
