The answer is, “it depends on how much development has been done to each car”. In the case of the time attack prepped Scion TC in this video, the answer is a boatload full of work. Details are somewhat lacking, but the car apparently dyno’d at 899 front wheel horsepower. Add a monster front wing for added grip in the corners, and you’ve got a Scion TC that can show taillights to a surprising number of other cars. The driver in the video was new to the Sebring track and was having brake problems, which explains his somewhat random choice of lines and braking points. Still, the soundtrack alone makes the video worth watching, and the TC’s disappearing act at 2:00 and again at 4:27 is nothing short of amazing.
