But bravo to them for actually building it. Its not too often that a vehicle gets an engine swap to quadruple the horsepower.

Less weight = less traction, but less weight also = less required force to accelerate at a given rate. Tires spin because there isn't enough traction to transfer the necessary force to accelerate the vehicle at a rate equivalent to the acceleration of the tire's rotation.
F = MA -> A = F/M
If you cut the mass in half, the required force to accelerate at a given rate is also cut in half (less inertia). Really, the biggest difference maker is the weight distribution and contact patch due to the weight. Obviously, this is oversimplified because there are numerous force vectors, but it probably doesn't spin as horribly as you would imagine. It has so little mass to move.
