Went to ForcedAirTech for a dyno day that I was sponsoring. I had Robert, owner/operator, put the NSX up on the dyno and see what she does. The NSX has a Intake/Headers/Exhaust/Stage 3 ECU setup with the stock airbox. That’s it.
The car made 274 RWHP and 209 ft/lb torque. The drivetrain loss factor is 13% which means the car makes 309.63 HP and 236.17 ft/lb torque at the engine. I’m very happy about this and pleased. I’ll have the dyno charts later and post them into this thread.
