Nitrous is king on the street period. Cost effective by far more hp per dollar spent than a blower or turbo. You hit it and you got all the hp/torque instantly. There are plenty of Mustangs running 500hp or more on plate systems. Heaven help you if you run into someone running a fogger on two stages..or maybe three.... No waiting for boost to build.....while your waiting I'm laughing all the way to the bank. That's real world street racing and not racing a dyno or cyber guessing to impress your friends.
