Hello All,
First, I only recommend the two stage for an experienced driver as thats alot of power to manage when the second stage is activated.
The Gasoline upgrade was developed to enhance the power output of the system. The propane is a wonderful additive, but the valving in the propane bottle is limited in size and only flows enough propane for supplementing about 160-170 rwhp worth of additional power with proper air/fuel mixtures.
Gasoline by itself is also limited in the amount of SAFE power that one can gain with his Viper in that gasoline has a higher specific gravity, is injected in liquid form(instead of atomized gas like NOS and Propane)therefore distribution problems can and WILL occur at high dosages of Gasoline.
We found that Gasoline and propane mixed together(propane helping to distribute the gasoline) makes for a very potent and even distributing combination, with bone stock Vipers gaining over 200 RWHP and over 350+ RWTQ with this combination.
The propane and nitrous system is perfect for the average user and can be upgraded to either our NGP or Two Stage system with ease. The propane bottle is DOT and ANSI approved for use in Vehicles and propane is an approved fuel additive for use in NHRA drag racing.
Please feel free to check the performance results section of my website at the link below for dyno runs and drag videos of some of our Vipers using these nitrous kits.
I hope this helps,
Tom
