As I am catching up on the "modern" z builds, 500+ HP seems way more common than it used to be. But they all seem to be very ass happy and kind of useless for grip performance. I feel like gearing changes could be very helpful. But as Jeep life has taught me there is a lot of give and take when gearing is played with.
I am trying to build my old car to play with the new cars. So 500 seems to be the happy medium of daily and not get smoked by a civic.
