I wouldn't pick on any hatch or CRX myself no matter what I'm boosting, considering those cars weigh as much as boxes-o-cereal.
That video seemed...strange. A 1G DSM at 18 psi with a 16G turbo should have found a lot more power at the top end, I'm not sure if his fuel management was set right. The Honda didnt sound right either...exhaust tone was too stock to be turbo...? It was a kind of a wierd race though... too short and both cars really did seem slow. I wouldnt say the DSM got owned, because they both seemed so sluggish. Wouldnt' call that a good race IMO.
