ScienceofSpeed TVS Supercharger - NSX, 1991-05

ScienceofSpeed's most ambitious project to date brings modern supercharger performance to the 1991-2005 NSX. Designed from the ground up utilizing CAD and CFD engineering tools, the ScienceofSpeed TVS Supercharger System offers V8 performance in a dependable easy to install package.

• Built from the ground up around the modern Magnuson TVS1900 Supercharger.
• Flexible upgradeable for 80 wheel horsepower (at 6 PSI, non-intercooled) to over 250 wheel (13.2 PSI) with supporting modifications.
• Wheel horsepower gain from factory power (243.8 wheel horsepower) - see dyno graphs in gallery:
• factory 3.0L, non-intercooled, 91 octane fuel: 147.8 wheel horsepower (8.5 PSI)
• ScienceofSpeed Stage 1 3.0L, intercooled, E85: 258.0 wheel horsepower (13.2 PSI)
• Plug-and-play - no permanent modification is required, and can be reversed at any time.
• An expandable design with optional integrated intercooler and 75mm throttle body.
• Improved belt tensioner system.
• Includes modern fuel & engine management system.
• Compatible with factory air injection system (1995-05 NSX).
• Fits under factory coupe engine cover (not compatible with factory targa engine cover or brace - see options below).
• Weight optimized (adds only approximately 29.4 lbs).

All systems:

• Magnuson TVS 1900 Supercharger
• ScienceofSpeed Inlet Manifold
• ScienceofSpeed Intake Manifold
• ScienceofSpeed Fuel Rails, Factory Fuel Pressure Regulator Adapter, & Fuel Rail Covers
• ScienceofSpeed Fuel Hoses
• ScienceofSpeed Belt Drive & Tensioner Assembly
• Griptec supercharger pulley & belt
• Denso alternator
• Accessories including alternator lead, hoses, and fasteners
• ScienceofSpeed Idle Air Control & Cold Start Valve Block (1991-94 NSX)
• ScienceofSpeed Throttle Cable Bracket (1991-94)
• Spark detection bracket (1995-05)

1991-94 Stage 2:

• ScienceofSpeed Link Engine Management System
• Dual AEM X-series Widebands (optional: Dual Wideband Bracket Kit)
• Injector Dynamics 1050x injectors
• Injector Resistor Bypass Buss Plug
• Walbro 255 LPH Fuel Pump & Installation Kit (can be upgraded)
• Fuel Pressure Sensor (0-100 PSI, part no 30-2130-100)
• Fuel Pressure Sensor Installation Kit (part no. enpp-442)

1995-05 Stage 2:

• ScienceofSpeed Link Engine Management System (with ScienceofSpeed 65mm Throttle Kit)
• Dual AEM X-series Widebands (optional: Dual Wideband Bracket Kit)
• Injector Dynamics 1050x injectors
• Injector Resistor Bypass Buss Plug
• Walbro 255 LPH Fuel Pump & Installation Kit (can be upgraded)
• Fuel Pressure Sensor (0-100 PSI, part no 30-2130-100)
• Fuel Pressure Sensor Installation Kit (part no. enpp-442)

• Stages:
• Tuner kit: no engine management or fuel system included.
• Stage 2: complete engine management & fuel system package (see included, above).
• Intercooler: ScienceofSpeed Intercooler & Intercooler Installation Kit. This optional intercooler is recommended for applications producing in excess of 140 wheel horsepower gains.
• Throttle Body: ScienceofSpeed 75mm throttle body kit. Increases power 12-25+ with larger 75mm throttle body.
• Targa Shock Tower Brace: the factory targa engine cover and engine cover brace is not compatible with the ScienceofSpeed TVS Supercharger System. A replacement brace is available. The factory engine cover is not compatible. Other engine covers may be used, including the ScienceofSpeed NSX-R Engine Cover. The targa top may be placed in the trunk.
• High Output Alternator: the standard alternator's capacity is 80A. This is the same alternator used by other supercharger kits. A 95A option is ideal for applications with aftermarket electronics, including stereo amplifiers.
• Supporting modifications: a free-flowing header and exhaust is recommended. The factory engine supports up to 140 wheel horsepower (3.0L) to 160 wheel horsepower (3.2L). Looking to produce 400-500 wheel horsepower? This is possible with an upgraded engine.
