A big 16G on a FWD CAN net mid to high 12s on a FWD DSM with the proper mods. A 20G is good for about a 12 flat on a FWD. A 20G on an AWD will net mid 11s. And these are both streetable turbos with full boost before 4k RPMS. And FWD will easily beat an AWD from a 30-40+ MPH roll (given both cars have the same mods). FWD DSM has about a 15% driveline loss, whereas the AWD is around 25%. Big difference. And with the proper suspension/wheel-tire setup, there isn't as much wheelspin as you would think.
