A friend of mine recently got his Viper back from a guy in Tampa. 1000hp...and it is unreal. The nitrous keeps the blower cool and the propane is there for when it is running too lean. He took me for a ride and it is too much, and he just had the street tires on. Check it out...not that it matter, but I have the yellow MP3 in the background. Figured I would mention that since it is a Mazda site...
