Development began by 3D-scanning the engine bay and 3D-printing a carbon-nylon prototype for real-world testing.\u003c\/p\u003e\u003cp\u003eThe design centres on a large venturi inlet tube with an integrated MAF sensor feeding a bespoke high-surface-area filter with a 170 mm (6¾\") opening inside a large, sealed airbox. The snorkel cross-section is twice that of OEM and the airbox volume is significantly larger, creating an effective velocity stack and a much smoother path for incoming air. The latest revision uses a short, quickly flaring GT3-style inlet tube and a dual-feed airbox similar to later 911 models, with CFD showing smoother airflow and a cross-sectional area roughly three times larger before the filter.\u003c\/p\u003e\u003ch3\u003ePerformance Testing\u003c\/h3\u003e\u003cp\u003eBoth road and dyno testing were carried out. On an inertia Dynojet, gains were +3–4 whp between 4500–5500 rpm and +6–11 whp over 6000 rpm, peaking at +11 whp @ 7000 rpm. On a load-based Maha MSR 500 dyno the curve was fuller, showing +6–8 whp from 4500–7300 rpm with no low-rpm loss. This equates to roughly +8–12 flywheel hp above 4500 rpm — a genuine, realistic gain over an already-efficient OEM intake. The latest revision recorded a healthy +15 wheel hp.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e+8–12 flywheel hp (real-world, above 4500 rpm)\u003c\/li\u003e\n\u003cli\u003eLarge venturi inlet tube with integrated MAF sensor\u003c\/li\u003e\n\u003cli\u003eSealed large-volume airbox with bespoke 170 mm filter\u003c\/li\u003e\n\u003cli\u003eSnorkel cross-section twice the OEM area\u003c\/li\u003e\n\u003cli\u003eTo be produced in pre-preg autoclave carbon fibre, gloss or matte\u003c\/li\u003e\n\u003cli\u003eImproved throttle response and induction sound\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNote: this product is currently in development.
