keep in mind that those supras aren't always putting down 900hp to the ground when street driving. most of the supras that put down that kind of power don't usually hit 900+hp till somewhere after 4500rpm's, and when i'm just cruising around i shift a little before 4k rpm. but yeah, there are quite a few supras with over 900hp that are street driven and some are everyday drivers.
