1,600 HP 5.0L 90° Hot-V Twin-Turbo V8

1:1 OpenCascade CAD Digital Twin, 6-Zone Cutaways, Volumetric Combustion & Dyno Lab

01 / What Was Built

Interactive, 1:1 metric-accurate 3D mechanical digital twin of a 5.07L (5,065.5 cc, 92.0 × 95.25 mm bore/stroke) 90° "Hot-V" Twin-Turbo Flat-Plane Crank 4-Stroke DOHC 32-Valve Hypercar V8 (1,600 HP @ 8,500 RPM, 9,000 RPM redline, 1,520 Nm, 2.20 bar peak twin-turbo boost). Every rigid mechanical casting, billet rotor, sprocket, and fastener is authored in OpenCascade B-Rep CAD (build123d) from a single shared metric blueprint, baked with Blender 5.2 Cycles Metal GPU 2K AO + Pointiness PBR maps, and driven at 60 Hz in Three.js (0.187.0, WebGL2, HalfFloat MSAA + AgXToneMapping) with clickable cutaway covers, 0–100% coaxial Exploded View, Solo 3D part isolation, raymarched 4-stroke combustion, EGT blackbody header incandescence, and procedural flat-plane WebAudio synthesis.

02 / Creation Pipeline & Workflow

Engineered with Gemini Carbon from a single shared 1:1 metric blueprint across seven OpenCascade B-Rep CAD (build123d) sub-assemblies — billet dyno stand & 6-bolt bedplate, closed-deck 90° V8 block with Nikasil liners, 180° flat-plane crankshaft with forged H-beam conrods & 3-ring pistons, 32V pent-roof DOHC heads with swept helical springs & VVT cam phasers, dual 136-link roller timing chains & 4-stage dry-sump pump, equal-length swept Inconel 625 Hot-V 4-into-1 headers & counter-rotating twin ball-bearing turbos, and 8 gold-anodized ITB velocity stacks with twin liquid-to-air charge coolers — baked with Blender 5.2 Cycles Metal GPU 2K AO + Pointiness PBR maps and driven at 60 Hz in Three.js r187 WebGL2 with 20-step raymarched 4-stroke combustion, Planck EGT blackbody incandescence, and procedural flat-plane WebAudio synthesis.

03 / Scene, Simulation & Optical Highlights

01Scene & Scale: 1:1 metric motorsport dyno test-cell assembly (0.880 m wide × 0.650 m engine height × 0.790 m core length on a 1.120 × 0.880 m grounded billet dyno cradle; crank centerline at Y = 0.520 m, 100.0 mm bore spacing, 21.0 mm right-bank rearward offset).
02Live Simulation (60 Hz): Exact tilted-bank slider-crank reciprocating physics across all 8 pistons & forged H-beam rods (1-8-2-7-4-5-3-6 flat-plane firing order at 90° crank intervals), 0.500× quad hollow camshafts actuating 32 canted Ti/Inconel valves + compressing helical springs + DLC buckets, 136-link advancing roller timing chains (21T:42T sprockets), scrolling 6PK serpentine belt, throttle-coupled 8 brass ITB butterflies, and counter-rotating 165,000 RPM twin ball-bearing turbochargers with boost-lag and throttle-lift wastegate flutter.
03Optics & Rendering: Dedicated HalfFloatType MSAA render target sanitized into a samples: 0 EffectComposer (UnrealBloomPass + lens fringe/vignette + AgXToneMapping), 20-step raymarched 4-stroke volumetric combustion (Intake tumble mist → Compression golden swirl → CDI Spark plasma arc → Power cellular Planck flame → Exhaust scavenging), arc-normalized EGT blackbody incandescence across 4-into-1 Inconel 625 headers & turbine volutes, and Fresnel X-ray Gas Flow streamlines.
04User Controls: Docked glassmorphic Dyno Control Deck (Throttle / Load 0–100% + Idle / Cruise / Redline presets, Live 60Hz / 4-Stroke Slow-Mo / manual 0°–720° crank-angle scrubber, live 8-cylinder stroke matrix, 0–100% coaxial Exploded View, Gas Flow X-ray, Subsystems color-coding, Rotating Only), top-bar Open All / Close All cutaway switch + Sound: On/Off, direct 3D raycast cover toggling & part picking, Component Inspector Drawer with Solo 3D isolation, and damped OrbitControls.
