ASNU’s SEMA award winning ITB system for the R35 GTR - Aids throttle response as the plenum no longer has to be pressurized after opening the throttle - Increased runner and plenum volumes allowing for bigger HP and torque - Built to allow the more extreme cam profiles to be used in a road situation with minimized idle problems - 60% increase in throttle area over largest twin throttle currently available (72mm) - 74mm Plenum inlet flange that can be increased to 78mm ( 23% increase in flow over 72mm twin throttles ) - Light weight alloy plenum housing to withstand extreme boost at a high fatigue life - It ensures a more equal distribution of workload across all cylinders by the engine allowing more HP to be generated safely - Plenum optimized for volume and flow using F1 technology - Complete with 6 additional ASNU SC injectors in a location optimized for that specific design - High flow upper fuel rail utilising -8AN fittings with a 17mm internal bore - Upper fuel rail designed to operate with integral fuel pressure & temp sensor - Designed to operate with the ASNU R35GTR fuel rails with pressure sensor (requires sensor to be relocated to the upper rail location) - Designed and machined with pre center drilled bosses for Nitrous or ADI/water methanol injection - CNC machined from billet 6082 & 7072 Alloy. - 8AN vac balance pipe between banks to give a good idle and avoid traditional ITB setup issues. - 8AN Boost balance pipe. - Vacuum and boost ports, with brake booster vacuum take off - Designed to operate with the GTR’s original throttle motor internals (not supplied) - Utilizes stock MAP sensor (not supplied) - Constructed to road car levels of durability, allowing extreme HP daily drivers - Integral air trumpets built into the plenum back plate
