The Black Widow Spider plate is the most advanced and unique carb plate ever invented, offering all of the advantages of any conventional plate and the advantages of a Direct Port (Fogger type) system, without the disadvantages of either.
The Black Widow Spider plate features;
• The most advanced technology ever applied to a plate design. This incredible design not only looks impressive but more importantly it will produce outstanding results on all V8 vehicle applications.
• A massive 700 HP flow capability with dual 350 HP nitrous and fuel Pulsoids.
• An even more impressive 1,000 HP version available to special order.
• CNC Billet alloy construction with stainless steel fittings.
• Optimised flow path through the Spider to minimise loss of density.
• Perfect distribution to all cylinders.
• Uniquely shaped discharge tubes (legs), which when combined with its unique flow path, ensure minimum phase change and maximum nitrous density arriving in the combustion chamber. These result in the best performance gains from the least amount of nitrous.
• Discharge tubes manufactured from malleable brass, which can be individually contoured to optimise the point of injection to suit different inlet manifold designs.
• The design is so flexible that it can be supplied to suit a vast range of applications, although we currently only have them available for Holley type 4150 and 4500 carbs.
• Direct nitrous and fuel feeds to each runner to maximise runner/cylinder filling efficiency.
• The unique ability to be jetted at each discharge tube, which means tuning per cylinder is possible, in much the same way as a direct port (Fogger type) system.
• No obstruction caused by conventional spray bars as used by most other plates.
The following is a list of advantages the Black Widow Spider has over other plates;
• SUPERCHARGING of the intake runners due to discharge tube location.
• REDUCED fuel drop out and loss of nitrous density due to ZERO CONTACT with the body of the manifold
• PERFECTLY EVEN distribution to all cylinders, making it unnecessary to 'tune' individual cylinders.
• UNDISTURBED N/A flow to engine, allowing the engine to run EVENLY as it should!!
• INDIVIDUAL cylinder jetting should the manifold in use cause any uneven distribution.
• DIRECTIONAL discharge which can be adjusted to optimise the exact point of injection relative to the port.
• MAXIMUM liquid nitrous density delivery.
• MINIMUM flow losses.
• MAJORITY of pipe work inside the manifold results in the cooling effect of the nitrous flowing through the distribution network cooling the intake charge.
• DISCHARGE TIP design reduces phase change and turbulence, delivering a denser charge.
• ANTI-FUEL FREEZING and better atomisation due to the location of the fuel outlet relative to the nitrous discharge tip.
• NO OBSTRUCTION to airflow caused by conventional spray bar type plates.
The following list is of the advantages the Black Widow Spider has over direct port systems;
• ANTI-REVERSION discharge tube location due to the nitrous plume starting further back from the inlet valve.
• SUPERCHARGING of the intake runners due to discharge tube location.
• MUCH SHORTER pipe work of equal length to all cylinders resulting in higher flow capability and more instant engine response.
• DIRECTIONAL discharge which can be adjusted to optimise the exact point of injection relative to the port.
• MAXIMUM liquid nitrous density delivery.
• MINIMUM flow losses.
• MAJORITY of pipe work inside the manifold results in the cooling effect of the nitrous flowing through the distribution network cooling the intake charge, rather than wasted to the external air.
• DISCHARGE TIP design reduces phase change and turbulence, delivering a denser charge.
• ANTI-FUEL FREEZING and better atomisation due to the location of the fuel outlet relative to the nitrous discharge tip.
• NO OBSTRUCTION to port airflow.
