Statistics
Smooth performance every day
01
Launch control
Get the best standing start possible with our special launch control feature. Set your RPM launch point and then let the ECU do the rest to manage traction off the line.
User adjustable launch points only available for models fitted with cruise control, otherwise possible with ECU Connect.
02
flat foot shift
Allowing the driver to keep their foot planted on the accelerator whilst changing gear minimises shift times, keeps maximum engine speed & torque ready for the next gear.
03
switchable maps
Four stage switchable mapping adjustable on the fly, 98+, 95RON (E5/E10) fuel modes, Valet Mode, Race Mode, etc
Stage Switchable Mapping Only Available for Models Fitted with Cruise Control, otherwise possible with ECU Connect.
04
downshift
auto-blip
The Auto Blip feature applies a short burst of throttle when the driver is down-shifting, which is particularly useful under braking. This raises the RPM to help provide a smooth entry into the lower gear by reducing the engine-braking effect.
small
but mighty
Based upon the Rotrex C30-94 Centrifugal design with superior efficiency, silent operation and self contained oiling system, combined with it’s unique patented traction drive technology it offers the smoothest linear power delivery. The supercharger supplies airflow of up to 0.39kg/s reaching impeller speeds of up to 100,000RPM combining small size with exceptional performance & durability.
If left unrestricted would go onto 430BHP!
smooth
power delivery
Our Supercharger kit's true strength lies in exploiting the exceptional balance and poise the chassis has from the factory. Retaining the car's OEM smooth, linear power delivery characteristics, with no spikes in torque are in keeping with the MX5's character.
FRONT mounted intercooler
+ cold air intake system
Fitment behind the front bumper, offers protection from the elements & is the perfect location for cooling down the charge air generated by the Rotrex, offering reduced heat soak for a maximum safe power and reliable horse power increase. Using a high quality core, hand fabricated & welded by highly skilled craftsmen, our inter-cooler offers excellent thermal properties, flow characteristics & all with minimal pressure drop. The reusable foam air filter can be cleaned at service to maintain maximum performance & air filtration properties.
industry leading
tuning
Using industry leading ECU tuning allowing a true and clean re-calibration of the standard ECU.
Our MX5 supercharger is calibrated using a powerful tools to add special features such as Launch control and switchable maps.
increased performance
Our Stage 2 Supercharger delivers 280/300bhp, 75-85% more than a stock Mazda MX5, whilst our Stage 1 Supercharger develops 230/250 bhp.
That is 50-60% more than stock depending on the type of exhaust manifold (and primary diameter).

bbr Fuel Module
Past 250bhp included with stage 2, we address the dead end fuel system with our in-tank module
Housing a 500BHP fuel pump and boost compensated fuel pressure regulator we overcome the fuel pressure drop found on the stock system. This means we can use smaller injectors to maintain OEM idle and drivability characteristics. Finished off with an engine bay mounted fuel filter and billet anodised bracket, this now makes fuel filter changes possible unlike the stock system.

faq
We restrict the Stage 2 kit to 300 BHP to maintain reliability on the stock engine. A forged engine and other supporting hardware is required to maintain 400+ BHP. Please contact us for more information.
An uprated exhaust manifold is required for both kits. For Stage 2 we recommend an uprated clutch & full exhaust system.
Yes, for competent enthusiasts the kit is available from our website.
With any performance vehicle we always recommend the use of the best fuel available to you. Our preferred choice is Shell V Power (99RON). Lower octane calibrations are available.
The MX5 has a very good stock brake setup, if used on the track or driven hard we recommend a disc and pad upgrade. Please contact us for more information
The MX5 is a very nicely balanced and setup from the factory. We recommend a good alignment setup and a set of BBR lower springs with Koni dampers if driving hard or on track, for more track focused coilover options please contact us for more information.
1 year parts on all components
At cruise conditions the fuel economy should be unaffected.
The Rotrex oil should be changed every 50,000 miles or two years whichever comes sooner.
This kit will only fit the 2005 - 2015 Mazda MX5 NC. While development has been completed on a 2.0 engine this kit will also fit the 1.8. (power fiqures for the 1.8 will differ to the 2.0)
We will be updating the site with NA, NB and ND versions as and when they launch.
A bespoke 2.5 version is now available. Please contact us.
