Show original supplier description
The Track Dog Racing TDR-94ROT is a comprehensive supercharger kit designed to significantly upgrade the performance of compatible Miata models. At its core is the Rotrex C30-94 supercharger, paired with a 90mm pulley and a TDR air-to-air intercooler system for efficient power delivery. This kit is engineered to work seamlessly with a MegaSquirt MS2 PnP ECU and Deatschwerks 1000cc injectors, providing robust fuel and timing control. For drivetrain components, it is recommended to pair this kit with a SPEC Aluminum Flywheel and a SPEC Stage 1 Clutch, as the stock clutch is not designed to handle the increased horsepower. The kit also includes essential components such as an oil cooler, reservoir, supercharger mount and tensioner, custom TDR SC pulley, custom intake hose and filter, BOV and silicone hose setup, oil catch can, and a TDR header heat shield. The TDR Rotrex kit is lauded for its safe power delivery on stock 1.8L Miata engines, reportedly delivering up to 315 rwhp and 225 tq without requiring forged engine internals for levels up to 10-11 psi. The power delivery is described as linear and predictable, minimizing stress on the drivetrain compared to some turbocharger setups. For those seeking even more power or enhanced reliability, Track Dog Racing offers recommendations and customization options, including engine building services and upgrades like the MAZDASPEED motor mounts, TDR Aluminum Race Radiator, and M-Tuned Coolant reroute kit.
