URD worked with a new start up company, iTronix Technologies, to meet our specific needs with a highly advanced self tuning engine management system for our high power supercharger kits. It is called the UCON Flex.
iTronix exceeded our expectations and developed an EMS that is significantly better than what we had been using.
URD was the first to release a forced induction system for the 2005+ Tacoma V6. Over the years we have made one major revision to the system and now we are shipping the latest revision called the Mark3.
This revision mostly involves a revision to the intake and charge piping system. The center of this is a new custom air filter box that houses a very large panel type air filter. This draws in the induction air from outside of the engine compartment for a cooler denser charge. The MAF sensor has been relocated to the charge pipe closer to the throttle body. This improves the idle stability with the very large fuel injectors. The system now includes a turbo style blow off valve. The overall layout is much more compact and cleaner looking.
The URD Supercharger system has always been the most power supercharger system available and it still is. The system is available in three performance levels called stages. The Stage 1 offered here is the basic kit installed on a completely stock truck. Stage 2 and Stage 3 upgrade kits are available separately.>
The key to producing this power level safely is in depth calibration work using highly advanced engine management and a properly configured fuel delivery system. For engine management the kit uses the UCON Flex Advanced Engine Management System that is self tuning with active dynamic air fuel ratio correction. The UCON also has engine protecting engine guardian features. If things start to go wrong the guardian features step in and depower the engine to protect it. If the air fuel ratio deviates from the programmed value and the dynamic active fuel control cannot correct it, the guardian will depower the engine to protect it. The guardian feature also steps in if the engine begins to overheat and we also program it to limit the maximum RPM until the engine is properly warmed up.
The fuel system includes a large 255 liter per hour fuel pump that is installed in the fuel tank and high flow fuel injectors that are more than twice the flow rate of the stock ones. These upgrades are required to ensure a sufficient supply of fuel is delivered to the engine as commanded by the UCON Advanced Engine Management System.

URD has chosen the highly efficient Rotrex C38-81 supercharger as the center of this supercharger system. The Rotrex is most advanced supercharger design on the market today. It features a small compact foot print with almost completely silent operation, with a very highly efficient traction roller drive system that will spin the turbo type impeller 7.5 times faster than the belt drive pulley is turned. This high step up ratio and small diameter turbo style impeller brings boost in sooner than other more common types of centrifugal superchargers. This gives you very nice off the line performance combined with unmatched top end power. The Rotrex Supercharger features it own self contained oiling system using Rotrex\’ proprietary traction oil that is the key to the advanced traction drive system. Rotrex warranties their superchargers with an industry leading one year UNLIMITED mileage warranty.
The air intake system brings in cool air from the stock location in the fender wall and into a custom air filter box which is CAD designed and flow optimized. This configuration makes it compatible with off road snorkle systems.
The overall operation of the supercharger system is nearly completely silent, but we have added a turbo style blow off valve will announce that your Tacoma indeed boosted. When the throttle is suddenly closed when the engine is at high RPM like shifting gears with boost, the blow off valve will cycle with a very crisp note typical of high performance turbo systems. It is always a crowd pleaser!!
The kit includes all the needed brackets, parts, and fasteners to allow a trouble free, no hassle installation. We include high quality stainless fasteners where possible, and all the parts have a high quality wrinkle black powder coating finish that will last and looks fantastic. The piping is all mandrel bent high quality aluminum they fit like they are supposed to. Only the best in kit components are used.
The installation on your Tacoma straight forward and the only modification to the vehicle require is some slight trimming of the radiator core support to pass the charge pipes through. No part of the kit runs under the truck or frame and the skid plates do not even need to be removed for installation.
We made every effort to make the system compatible with off road winch bumpers. We can\’ guarantee compatibility with all bumpers on the market, but several of our V6 kits have not had any problems with the different winch bumpers on the market.
Want even more??? The basic kit uses the Rotrex C38-81 supercharger, but we have designed in expandability for those that want to go extreme. The supercharger mounting bracket and belt drive is designed to accept the larger Rotrex C38-91 supercharger. The larger superchargers will require a race built engine and larger fuel injectors.
URD has worked very hard to bring you the finest supercharger kit for your Tacoma and we are very sure you will be very happy with it!!
