I agree, and I'm not downplaying the achievement that it is. Just pointing out it's impracticality in a street setup. (and in some cases even a track setup)
It reminds me of Dynoflash Al's Evo back in the day. Anyone familiar with the car will remember how he made 1000whp on some ridiculous large turbo ( I say ridiculous in relation to the displacement of the motor). Buschur was running 9.1 ETs with 200 less HP and his car weighed a few hundred more pounds. So everyone assumed Al would run deep 8s. The truth of the matter was that he couldn't keep the car in power. It's average HP was less than the Buschur car, and after many failed attempts at the track and the car becoming useless on the street, Dynoflash disappeared from the Evo scene.
