The VCN-500 Recluse provides hidden power at the touch of a button. This inexpensive dry system is built using VENOM’s patented closed loop fuel control system which ensures the proper air/fuel ratio under all operating conditions. The Recluse actually takes control of your engine’s stock fuel injectors to inject extra fuel during nitrous delivery. Like our other nitrous systems it contains an advanced microprocessor system that terminates the flow of nitrous if the air/fuel mixture becomes too lean. With a sleeker bottle and non-descript wiring harnesses it is an ideal setup for those who want to make their nitrous system less obvious to their competition. No modifications to fuel pressure are required and best of all it works on all new fuel systems that do not include a fuel return line. Give your 4cyl an extra 70, rear wheel horsepower. A 6cyl can obtain up to 90 additional horsepower, and an 8cyl will top out at an additional 110hp.
