SPORTSTAR Plate System- Holley 4150/Carter - adjustable from 50-250HP
The NS SPORTSTAR series was engineered for more aggressive applications and engines of 300 CID and larger. SPORTSTAR systems utilize larger fuel and nitrous solenoids than our standard POWERSTAR systems. SPORTSTAR plates are 1/2'' thick and designed to fit between the intake manifold and carburetor. All Nitrous Supply systems are equipped with a bright candy red nitrous bottle (10 lb capacity), high flow valve, different jetting stages, aircraft quality stainless braided line, steel bottle brackets, as well as all needed electrical and mounting hardware for a no hassle installation.
PREREQUISITES SPORTSTAR systems require a fuel pump/system designed to operate between 5 and 10 PSI with a flow rate of 0.1 gph per horsepower at 6 PSI. As an example; an engine that makes 450 HP with the SPORTSTAR system engaged, will require a fuel pump that flows at least 45 gallons per hour at 6 PSI. NS SPORTSTAR systems generate higher cylinder pressures under load increasing stress on pistons. For this reason it is recommended using forged pistons for extra strength. In addition standard ignition systems may misfire under higher cylinder pressures and higher rpm levels. Therefore a high performance ignition with an adjustable timing feature is recommended.
