Summary by Krater

A review of a supercharged Mazda MX-5 Miata on the dyno and the road, comparing power, torque, acceleration, and throttle feel against stock and NA-tuned setups, ending with getting pulled over by police.

From the video

Answers: What are the performance gains and drivability changes of supercharging a Mazda MX-5 Miata?

• Mazda MX-5 Miata supercharger installation and performance
• Dyno testing stock vs tuned Miata horsepower and torque
• Real-world acceleration and G-force measurements in gears 1-3
• Throttle feel and electronic throttle challenges on project cars
• Transmission reliability modifications in project cars

What it concludes

• The Fab9 supercharger tune increases wheel power to 210 horsepower and wheel torque to 188 lb-ft on the Mazda MX-5 Miata.
• Supercharging flattens and raises the torque curve across the entire rev range compared to the stock and naturally aspirated tunes.
• Acceleration in first gear reaches 0.65 g's with the supercharger, closely matching the Honda Civic Type R.
• Modifying a car by adding a supercharger and other performance upgrades decreases long-term transmission reliability.
• Electronic throttles introduce noticeable low-speed shift blips and abrupt pedal closure feel compared to mechanical throttles.
