3. 70055 and square flange 4 bbl carburetors Part 70056 Horsepower and torque increases can vary with engine displacement equipment upgrades and modifications Approximate power increase estimates can be made based on the mass flow of nitrous oxide into the engine These types of systems utilize an adjustable plate that sandwiches in between the throttle body and the throttle body mounting pad on the intake manifold The adjustability comes from the ability of the plate to accept different orifice sized jets The plate has jet fittings at opposite ends of the plate that control the amount of nitrous oxide and fuel flow into the engine This system has been designed with some flexibility as to where certain components can be located within the engine compartment The electrical components have properly sized and ample lengths of wire for some flexibility on where voltage signals are intercepted on the electrical system The solenoid and microswitch brackets have a universal shape to allow for adjustability in placement and location of these components The solenoids have ample feed line lengths for many different manifold air cleaner throttle body configurations and the microswitch bracket will allow for several different positions This system includes the bottle shipped empty bottle feed line and universal footprint steel bottle brackets The mounting brackets also include rubber insulators to protect the surface of your nitrous bottle while m
