I bought the kit but then I got oreders and needed to buy a house so I have to sell some things. Here is BTR Vipers Premium N20 Propane Gas Injection kit with N20 Progessive Launcher. The launcher is a cool little touch screen and the kit is suppose to be safe on our engines because of the propane and extra fuel added.

TWO STAGE-NOS-Gasoline-Propane…For gains up to 300+ Rear Wheel Horsepower and 500+ Rear Wheel Torque - $ 2,990.00

For the Connoisseur. Our newest combination of power that when installed is unmatched in power and torque by ANY product for your Viper at ANY price! Bolt this on your stock Viper for incredible gains with NO ill effects as air fuel ratios with the gas-propane combination are very conservative, compression is not increased, cylinder temperature and pressures are far lower than those of other forced induction type power adders and the price for dollars gained is second to none in our industry.
