Calling all NSX’s, S2000’s, Type R’s, Type S’s, and any other performance Honda’s/Acura’s.  Join ScienceofSpeed on the morning of Jan. 10th as we host our annual New Year’s meet at our facility in Chandler.  We will be meeting at 9:00am-Noon, and opening our shop for tours, information, and sales.  We will have a live DJ on hand, and staff here to answer questions you may have.  Come see other performance cars, and this meet is a great opportunity to check out the parts you’ve been desiring on other cars, and asking other owners for their recommendations and experiences before you buy.  
ScienceofSpeed will have doughnuts, snacks, and drinks on hand.  We are also working on having a coffee truck to help you get your day started, and a DJ to keep the tunes rollin.  

35 years of NSX performance is starting to show its age.  Rubbers, plastics, seals, wires, etc., are all aging with or without use.  One issue we have seen increasingly is the electronics issues.  Electronics are older units, sometimes more than 35 years old at this point, and should be treated as a service item, much like a timing belt service.  Most owners of the first gen NSX have already experienced issues with the stereo, amps, Climate Control Unit (CCU), Electronic Power Steering (EPS),

As the first-generation NSX continues to age, failing electronics have become more common.

The most common issues include PGMFI relay, climate control unit, and stereo amplifier unit failure. The typical climate control unit (CCU)  failure symptom is the fan motor only blowing on high and/or the unit no longer powering up. The typical symptom of stereo amplifier failure is popping and/or reduced volume from the speakers. As for the PGMFI relay, no repair program is active and would require replacement of the relay upon failure. 

Lately, new electrical component failures have been reported, including issues with the stereo head unit, instrument cluster, Turn signal cancellation module, and electric power steering control unit.

The failures in the climate control, stereo amplifier, and recently the stereo, instrument cluster, Electric power steering control unit, and turn signal cancellation module are related to the electrolytic compound leaking from the

A new horsepower record was achieved with the ScienceofSpeed TVS Supercharger System! This 1992 NSX features ScienceofSpeed's TVS Supercharger, TVS Intercooler, and Stage 2 3.2L Engine and produced over 520 wheel horsepower (approximately 580 horsepower at the engine).

With the larger engine, intercooler, and lowered compression ratio, this configuration normally produces 12-12.5 PSI. A slightly higher, but still very conservative, boost pressure of 14 PSI was achieved by replacing the factory manual transmission pulley with an automatic pulley. The automatic pulley has a larger that drives the alternator, and thus the supercharger (approximately 150.5mm compared to 141mm). This larger drive pulley drives the supercharger faster.

Here are the components used in this build:

At ScienceofSpeed, we know that the Pure900 turbochargers produce significantly more power on both the dyno and street based on engine performance data  (significant increases in airflow compared to the factory turbochargers). Air mass allows us to quantify how much air the engine is consuming, which directly translates to power. The Pure900 turbochargers flow more air and produce more power all the way down to 2,000 RPM compared to the factory turbochargers. In fact, Pure900 turbochargers using E40 fuel produce an increase of over 200 wheel horsepower and nearly 200 lb-ft of torque compared to the factory turbochargers.

A big factor in acceleration performance is tire traction. When engine performance is increased with these upgrades, marginal tire performance becomes the bottleneck.

When launching from a standing start, the factory modules use inputs from sensors to minimize wheel slip and improve tire traction. If the engine produces more torque, wheel slip may increase,

 A very common topic one will encounter on NSX forums, community conversations, and personal ownership are issues with the driver and passenger window functionality. The three most common of which are slow raising speed, rocking or binding when moving the window upwards, and the window completely dropping in the door altogether. ScienceofSpeed has found the most common root causes of these issues and has developed replacement parts to keep your NSX windows functioning properly.

Slow raising speed: this is the most common symptom of three potential issues. First is lubrication, second is window misalignment, and third is a worn-out regulator motor. Lubrication and inspection of the window alignment should always be first on the list when addressing this issue. This should also be a part of your routine servicing to keep the window regulator motors from wearing out prematurely. To find info about the process and equipment needed for this, refer to the official

ScienceofSpeed's NSX Vintage Parts Program seeks to offer discontinued, backordered, and difficult to source factory components for the 1991-2005 NSX. ScienceofSpeed has collaborated with Honda, Acura, and aftermarket parts sources to continue production where available and to source old stock components from worldwide sources when discontinued. While initially including only genuine Honda components, this program will include ScienceofSpeed produced components once certain parts become discontinued or generally unavailable (all genuine Honda parts are labeled as such). Parts available are sourced globally and pricing can vary significantly over time based on cost for the items sourced. ScienceofSpeed includes international import costs in the price of our products. Current prices are reflected on our website.

Mega power increases are now available from ScienceofSpeed for your NSX race car!

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.
