just looking at the "contraption" reminded me of one "ol mate" made down the road from our place. he was hell on wheels and was always hooning big time. He ended up with a Cortina effectively stripped to the chassis with a seat and steering wheel. it had a 302 shoe horned in and he smoked the tyres everywhere all over the district.
His great trick was to run down all the "new" plastic white posts on one particular strip of road and did this regularly until one of the locals got pissed off with noise and slipped a star picket behind one of the posts.... that was the end of the rocket....
