the supra definitly will get the win. its alot more aero dynamic then a cobra is. also with such a large single turbo conversion it will have monster top end. the combination of the 3
1: more aero dynamic ( its known that to go double the speed you need 8 times the hp depending on the frontal area of the vehicle and the co efficient of drag of the car ) so the supra has this part down.
2: more hp. which helps even more in the top end.
3: power delievery of the a large single turbo vs. a linear power band of a super charger
the supra's making that kind of power has been known to take out super charged vipers on the highway and twin turbo 5.0's on the highway. almost nothing can top a supra's high end. since this is no ordinary 1/4 mile drag they will approach speeds of around 160+ mph. the Cobra will take the lead on till around 80mph that is when the supra will finally hit full boost in 3rd gear. then the supra should walk the cobra all the way to 160-170mph.
there are also videos floating around with a 650whp cobra vs. a 550 whp Z06 vette and the vette took it on the highend. same reason the vette is more aerodynamic and is lighter. all though the supra is heavier then the cobra. its more sleek and plus its got around 100 more whp.
the supra will definitly win this.
