KraftWerks Miata Supercharger Kit
Good-Win Racing is proud to introduce the new completely redesigned '90-'93 KraftWerks Rotrex Miata INTERCOOLED Supercharger system.

Only configuration currently available is for Miata with BOTH A/C and Power Steering.

Like all KraftWerks supercharger kits, Miata systems are based off of the impressive Rotrex supercharger and include everything necessary for a truly bolt-on installation.

At the heart of each KraftWerks Miata kit is the Rotrex C30-74 centrifugal supercharger. The Rotrex patented traction drive technology works unlike any other supercharger, and means that power is always available, all the way to redline. The results are impressive: 170 hp and 125 lb-ft torque on 1.6L, 90- 93 models.

Each Miata supercharger system is a comprehensive design and includes all necessary components to ensure safe, reliable operation. Standard-issue with each kit is a large and efficient front-mounted intercooler to help ensure low intake air temperatures for optimal performance. All necessary aluminum tubing, silicone couplers, and clamps are also included for easy installation. Proper air/fuel ratios are ensured with the included Grams Performance 310cc/min. fuel injectors, DeatschWerks 255 lph fuel pump, and boost-dependent fuel management unit. Convenient, plug-and-play fuel injector adapters are also included, making each kit a true bolt-on experience.

Rotrex superchargers are renowned for their compact size, high adiabatic efficiency, low vibration, and quiet operation. Their unique traction drive technology is what makes all of this possible, which, unlike other superchargers, transmits power through frictional forces between its rolling elements. Each Rotrex unit features its own self-contained oiling system that remains independent of the engine. Its dual-action oil pump supplies traction fluid to the supercharger while the supplied cooler ensures proper fluid temperatures at all times.

The KraftWerks Miata supercharger system provides instant throttle response and a progressive power curve that increases all the way to redline without the typical spiking or surging turbochargers are known for. This unique, more useable power curve results in reduced cylinder pressures, less strain on engine components, and increased reliability. Rotrex superchargers also operate much cooler when compared to turbochargers and other supercharger systems, which reduces the engine intake air temperature as well as the risk of detonation.

BRIAN'S APPLICATION NOTES: The adjustable rising rate fuel pressure regulator is a classic simple fuel setup. To make more power and control it much more precisely, we suggest adding our DIY AUTOTUNE MEGASQUIRT PLUG-AND-PLAY ECU (which also allows doing away with the restrictive factory 'barn-door' style air mass sensor. NOT CARB LEGAL, which means legal in California for off road only (race tracks!).

Just wanted to thank you guys for the great stuff and great work done on my MX5 club yesterday. I could feel the difference in sound and performance right away! It drives and corners awesome now. Can't wait to tell my friends about you guys. I'll be keeping an eye on your web site for other goodies and events as well. Can't wait to try my new suspension out on a auto cross. Will definitely be trying it on some twisty roads this weekend. Just can't wipe that smile off my face when driving this car. Thanks again guys!

Brian, Thank you!!! We last spoke in November about some upgrades for my 2011 MX5 soft top. It has finally warmed up in NE Ohio and two relaxed weekends of wrenching on my car were well worth the effort. Installation of the RoadsterSport ceramic coated street header was straight forward and took under 8 hours, including a 40 minute test drive and cleanup of the garage! Combined with the RoadsterSport Q exhaust, the sound is fantastic and the increased torque, horsepower and performance make it a blast to drive. The addition of the Cobalt shock tower brace, Racing Beat sway bars, ILM front power train and X braces really enhanced the ride - minimal body roll, comfortable and very responsive. Your recommendations really helped transform the car from great to fantastic. Your research, product development and candid recommendations make you a standout in the industry. My only questions are - what's next on my list .... And how soon will my wife want the same upgrades on her 2012 PRHT ... Again, thank you!!! Charles G
