The fast quarter time is because of the AWD 0-62 is like 3.8sec but get one on a roll and you take away the advantage. My freinds 993 turbo has chip,intercooler and b&b full exhaust and from a 20mph start I kill it every time. I had a 930 euro version of the 911 turbo but RWD with upgraded turbos,intercooler group B race cams euro fule lines chip and full exhaust and it was about 500hp but only ran mid 12s because no AWD.
