Nitrous. It will make pretty comparable power to a blower but the torque will be noticeably higher in most cases.
My car probably puts down 375-380ish at the wheels, but probably in the lower 500's of torque on spray.
It's instant and if you can get a nitrous car to hook, launches are just silly.
Unfortunately for me... my car won't hook (yet) and the clutch can't hold the spray (yet).. haha.
