ScienceofSpeed Ethanol Monitoring Kit
Take advantage of the performance advantages of ethanol FlexFuel by using the Ethanol Monitoring Kit from ScienceofSpeed. This allows you to pre-mix

How much power does the KTuner Flash V2 produce?
More than 40-60 horsepower depending on fuel used (91-93 octane) with the stage 1 map. For more details, see the product page for dyno results.

Are other components required?
Downpipes are recommended and increase power output by 15-20 horsepower.

How long does the flash process work?
Once setup, maps can be flashed to the ECU in 3-5 minutes.

Does the KTuner Flash V2 need to stay connected to my vehicle?
No. The unit only needs to be connected during flashing, gauge viewing, or datalogging. Once the ECU is flashed, it can be disconnected.

Is the JB4 Tuning Box compatible with the KTuner Flash?
No. The JB4 should be disabled or removed. See instructions included with the KTuner Flash for details.

For a limited time, NSX Type S Exclusive Paint Matched Manifold Cover Red Charge Tubes are Available Now!

Frequently Asked Questions

• What power and torque does this produce?
The engine is rated for 306 BHP and 295 lbf-ft of torque with 91 octane (at the engine). In ScienceofSpeed’s testing, the engine produces over 300 horsepower and lbf-ft of torque at the wheels with HPD’s fixed-calibration ECU with 91 octane fuel and factory S2000 exhaust muffler and catalytic converter. Much higher output is possible with higher test fuels, including FlexFuel, and turbocharger and engine upgrades. Higher output requires a configurable ECU (a MoTeC M142 based solution is available).

• What is included in the conversion kit?
There are nine major components: engine, engine mounting kit, intake manifold adapter and intake kit, exhaust downpipe kit, transmission adapter & flywheel kit, engine coolant kit, intercooler, fuel system, and engine control package.

• What clutch kit is required?
The ScienceofSpeed transmission

High horsepower modifications to the NSX have become more common. Increased power increases engine fuel demands. With the introduction of high fow turbine fuel pumps such as the Aeromotive 340 LPH and Walbro 450 LPH fuel pump, customers have the ability to install a fuel pump capable of supplying high horsepower applications using the factory in-tank fuel carrier. Initial testing performed showed the Aeromotive 340 HP pump performing similarly to the lower capacity Walbro 255 HP pump with factory wiring. Upon investigation, it was clear that resistance from the factory fuel pump wiring was causing a voltage drop down to less than 11 V at the pump. The factory wiring consists of wiring between American 16 and 18 ga wiring. Resistance is further increased from the relatively long run of approximately 8 ft of wiring from the power source. Testing was performed using a twin turbocharged 1993 NSX with a maximum total gasoline fuel supply demand of 270 lph at 750 horsepower at the engine. Manifold

ScienceofSpeed has expanded our throttle body options available for 1995-2005 NSX race cars when used with the ScienceofSpeed AEM Infinity Engine Management System.

Three options are now available:

• 65mm: compatible with factory rubber coupler. Ideal for naturally aspirated or supercharged applications compatible with the factory coupler (this is the standard throttle body included in the ScienceofSpeed Stage 2 TVS Supercharger System.
• 70mm: not compatible with the factory rubber coupler. Designed for 3" couplers - popular with turbocharger systems.
• 75mm: designed exclusively for the ScienceofSpeed TVS Supercharger System. Not compatible with the factory intake manifold. Requires the ScienceofSpeed 75mm Throttle Body Kit for

With CT-Engineering's closing in 2018, ScienceofSpeed lost its supplier of components for the ScienceofSpeed Supercharger Kit. The loss of these positive displacement supercharger systems left a big gap in forced induction options for the NSX enthusiast.

Now in development, the following is a technical introduction to the ScienceofSpeed TVS Supercharger System.

BACKGROUND
Positive displacement superchargers for the NSX are unlike any other forced induction system (centrifugal supercharger or turbocharger) in the way they generate instant, low-end torque. Positive displacement superchargers give the impression of small block V8 performance without giving up the 8,000 rev limiter - keeping the characteristics we love about the NSX, but amplifying the engine performance.

The Comptech-based system had a number of advantages, including ease of

How does this system compare to the Comptech/CT-Engineering and CT-Engineering based ScienceofSpeed supercharger systems?
ScienceofSpeed partnered with CT-Engineering in 2007 to develop a high-output version of the CT-Engineering System. The CT-Engineering system produces around 80 WHP and the ScienceofSpeed system around 140 WHP using a larger 2.1L unit. CT-Engineering closing its doors in 2018 required ScienceofSpeed to develop the key components from scratch but have allowed improvements most notably in regards to the intake manifold (click here for more technical details). The improved design allows increased flow, reduced pressure fluctuation, and an optional integrated intercooler. Improvements to the belt drive tensioner system, the ability to increase throttle body size,

This month marks 3 years since we began working with the Second Generation NSX. "Caliente", this 2020 NSX Thermal Orange project, embodies everything we have learned (and love) about this very special supercar.

100 BHP gain over factory power, suspension lift system, downpipes & valved exhaust that work with the factory mode control switch while giving the car an aggressive exotic exhaust note it deserves, along with many cosmetic touches from ScienceofSpeed. Thank you to all of our customers for allowing us to be a part of your NSX experience!

Modification List:

• ScienceofSpeed Sport Downpipe Set
• ScienceofSpeed Valve-tronic Sport Exhaust

ScienceofSpeed offers the best AEM Infinity 506 kit for the S2000 with a plug and play bracket, a wire harness that allows easy and clean installation, and dash control for the 06-09 S2000. Did you also know that we also offer a kit that allows traction control on all S2000 years?

Using the Infinity’s built-in traction control system (which is far superior to the factory 06-09 system) and ScienceofSpeed’s wheel speed converter – you can program smooth traction control – which can be switched on or off with a switch (and the factory switch on the 06-09). You can even use a multi position switch to trim how much traction control you wish to be active.

The ScienceofSpeed Infinity system for 2006-09 even allows control of the factory VSA lamp and traction warning lamp for the ultimate in a clean tidy factory-like installation.
