This. My GT500 is sporting right around 650/670 to the wheels and it can be a handful with traction control on. You definitely don't want to go from driving something with < 250hp ( just throwing a number out there ) to something with 850, I noticed a HUGE difference gaining 200hp. In the end you're going to go for whatever goal, make sure you've got good tires and set the suspension up properly to safely handle the power.
