Introducing the WhitleyTune Sports Injection kits. A truly bespoke individual throttle body (ITB) solution for high performance naturally aspirated engine builds.
These ITB kits are not a one-fits-all approach as the entire inlet tract from port to airbox is 3D modelled and designed specifically to suit your application. We take into account engine specifications, intended application and physical packaging to produce the best fit for your requirements. The design intent behind bringing these kits to market is to service the enthusiast who has an uncommon application or requires a bespoke solution to suit their specific engine setup, whether that be a ten-tenths race car or a road-legal weekend warrior. We can make these kits to suit any engine.
At the heart of every WhitleyTune Sports Injection kit is a one-off investment cast A356 aluminium intake manifold. The manifold is CAD designed and cast in-house using 3D printed patterns – this gives us absolute freedom to meet your personal requirements. All kits utilise our own design compact throttle bodies & velocity stacks, which can be in your choice of material, finish and colour. All components are CNC machined and hand assembled.
What is included in each WhitleyTune Sports Injection kit:
Full intake system design & 3D modelling, including tuned length and ideal runner & throttle body size calculations.
A single 3D printed plastic dummy intake runner, throttle and velocity stack to check for engine bay fitment (if required).
Bespoke A356 investment cast aluminium intake manifold – length, taper, position, aesthetic and finish all customisable
WhitleyTune individual throttle bodies – billet or cast, sized to suit the application and position in the inlet tract, 40-55mm diameter. 32mm length as standard, or 50mm length with integral injector port. O-ringed faces with sealed spindle bearings. Brass butterfly and slabbed throttle spindles.
Velocity stacks - 3D-printed Carbon-Nylon, cast A356 or 6061 CNC billet aluminium, any length or shape.
Fuel rail machined with mounting kit, AN8 ORB ports front & rear
Throttle cable linkage, throttle stop, throttle position sensor & throttle return springs
Bosses in each runner, tapped to suit vacuum fittings or our optional extra vacuum rail
Hardware & O-rings
Full intake assembled and ready to bolt on. Throttle bodies port matched to the manifold with the option of casting the intake manifold ports at the cylinder head flange slightly undersize to allow for customer port matching.
Integrated vacuum cross over tube for use with idle control valves, drive-by-wire throttle motors, O-ringed flanges, air filters, carbon air boxes, injectors, idle control valve with remote mount kit, fuel pressure regulator & fittings, ECU, Fuel system components etc
