Objectively speaking looking at the mechanicals in the 1320 (transbrake, torque reserve, Demon converter (higher K ratio), suspension, and a nearly 500hp engine) and it possible factory weight reduction (a lack of seats, hollow sway bars, and optional equipment deleted) - getting a single wheel up on skinnies on a well prepped track isn't outrageous especially with a sorted driver mod.
As for the other high powered cars that cannot achieve it - well wheelies aren't ideal anyway. But, the Demon has way more weight over the nose for starters.
