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:
