URD / Whipple Supercharger System MK2- Stage 1 2010-2024, 4Runner V6

URD has updated our supercharger kit for the 2010-2024 4Runner V6 and we call it the Mark 2 system.

The changes in the kit are minor and consist of adding 600cc primary fuel injectors and is now tuned with an ECU reflash calibration.  The kit includes the device that works with your Windows PC to flash our ECU calibration into your stock ECU.

This kit provides a nice gain in power and torque with a fuel economy penalty provided you drive it the same. This kit matches the 4Runner very nicely. Our testing shows a gain of 133 RWHP and 120 RWTQ with a low boost pressure of only 5.5-6 PSI. The kit features a 2.3 liter Whipple Twin Screw compressor that is oversized so there is a significant amount of headroom built into the system for future power stages. Very large compressor turning slowly and flows a lot of air through the engine.

Includes

• Whipple 2.3L Twin Screw Compressor with 3.5″ pulley
• CNC billet manifold adapter and inlet
• URD 255 LPH fuel pump/filter kit
• Denso IKH22 Iridium Power spark plugs
• All stainless fasteners where possible
• All silicone couplers with quality stainless liner clamps
• Dedicated belt drive system with all needed idler,  and tension pulley and uses overly crank pulley
• Use the stock air filter box for quiet operation and cold air induction
• High flow fuel injectors
• ECU Reflash kit.
• Very detailed installation instructions

The prototype system has been road tested for several years, from sea level to 14,000 feet, and from sub-zero conditions to 110 degrees F.  The system has been thoroughly tested.

• Peak gain was 123 RWHP and 93 RWTQ
• Max gain was 133 RWHP and 120 RWTQ

This was using a 2012 FJ Cruiser 4×4 with a manual transmission and 82,000 miles on it. Completely stock except for the URD Supercharger system using Shell 93 Octane gas. Dyno was URD’s DynoJet 224xLC using SAE correction factor and located in Owings MD very close to sea level. Boost peaks at about 5.5-6 PSI.

NOTE:  We have ECU calibrations for the US Market 4Runners.  If you have a non-US market 4Runner, you will need to pull the calibration ID that is currently flashed into your stock ECU and email that calibration number to us to see if we updated it with our calibration.  You should do this before ordering your kit.  There are some foreign market ECUs we cannot flash at this time.

Does require PREMIUM fuel with 93 octane preferred but can run on 91 octane using the US octane rating system.  This is different in other countries.

Pricing, specifications, hardware, and availability are all subject to change.  No discounts on this item.
