Description
This item includes a WRC-style Dual Plenum intake manifold DIY build kit with pressure box flow rings specific for a 3S-GTE engine.
WRC-style Dual Plenum 2-chamber intake manifold DIY build kit comprising a conical tube (primary chamber) and pressure box (secondary chamber). This intake manifold delivers uniform pressure and air flow across all cylinders for maximum power, torque and engine longevity, based on Swiss physicist Bernoulli’s Principle, whereby in a tapered/conical pipe, the pressure of liquids and gases flowing in that space decreases while their flow speed increases. The engine is easier to tune when all cylinders receive the same amount of air and can thus be set with the same optimal ignition advances. The engine will run harmoniously, making it easier to avoid knocking and other non-desired effects that compromise engine reliability and lifetime.
The build kit components are of lightweight, strong, corrosion resistant and highly machinable and weldable Al-6082 grade aluminum alloy, which is 5 times stronger than pure aluminum. The cone tube can flexibly be placed on the pressure box, facing front or back – depending on the boost pipe entry – and left or right, according to available space in the engine compartment.
The delivery includes all necessary parts including cone tube caps for both ends (the narrow end cap is flow-optimally designed) as well as a support rod for the cone’s air exit slit, which feeds air to the pressure box, to prevent the slit from expanding under extreme high pressure conditions. Detailed instructions for building the kit and welding are also included.
The following parts are included for building a Dual Plenum intake manifold for a 3S-GTE engine:
- CNC-machined engine-specific aluminum intake manifold flange
- pressure box halves forming secondary plenum
- 4 pcs. made-to-fit air flow rings for pressure box
- 4 pcs. profiled runner pipes between intake manifold flange and pressure box
- cone tube forming primary plenum
- flow-optimised end cup and cover plate for cone tube ends
- support rod for cone tube air exit slit
- detailed build and weld instructions
NOTE! The kit’s aluminum alloy components require AC-TIG welding
