From the beginning, our goal was simply to engineer the very best performing Miata supercharger kits. Kenne Bell has over 33 years of tuning and product engineering experience with turbocharging, intercooling and supercharging Ford, Chrysler and GM engines. We currently offer 21 kits with 6 more in development. Combine this expertise with the world's most efficient supercharger and revolutionary Laminova finned tube intercooler and the result is the ultimate Miata kit. The engine makes up to 10 more HP because it takes 10 less HP to drive the Twin Screw vs. the Roots style. And the charge temperature is up to 46° cooler. Finally, all Kenne Bell Kits also include 4 new high capacity fuel injectors and the pre-tuned OPTIMIZER which, without question, are mandatory for '99 up supercharged Miatas. And there is no additional tuning or tweaking required as with other kits.

• Billet aluminum supercharger and intercooler (others use cheaper cast aluminum).

The Kenne Bell OPTIMIZER re-maps and optimizes the fuel, spark etc. for the increased supercharger power. It even self compensates for boost upgrades and the intercooler.
Unsurpassed for heat transfer. The most advanced air to water intercooler available. 86% efficient. Lowers air charge temp to within 9° of ambient. Laminar flow through dense finned aluminum tube cores maximize heat dissipation while minimizing pressure losses. And it looks good on a Miata. Polished or black/satin.

The patented and widely acclaimed Twin Screw Supercharger is +90% efficient. It requires 30% less energy (HP) to drive and the air discharge temp is 30% cooler than the Roots type. The Twin Screw's lower parasitic losses - akin to a free set of headers - and the cooler denser air charge guarantees more horsepower and torque than other kits. Kits available in polished or black/satin.
