Story

Shadow Circuit Marauder is what happens when a 5.7 Hemi Ram stops pretending it’s a straight-line bruiser and gets rebuilt for midnight expressway apexes. The silhouette stays unmistakably Ram—high beltline, blunt nose, big shoulders—but everything around the wheels and under the bumpers is re-authored with Japanese time-attack logic: track width first, aero second, cooling always.

The widebody isn’t cosplay; it’s structure. Tubular extensions push the front and rear tracks out into TE37s and R888Rs, while a splitter that actually projects, a bed-cover diffuser, and a tall dual-element wing turn a brick into something that plants at speed. It’s street-adaptable in the way real street time-attack cars are: adjustable, overbuilt, and unapologetically loud in function even when the paint stays stealth.

Technical dossier

Fictional engineering concept

Platform

2009 Dodge Ram 1500 5.7 Hemi

Powertrain concept

5.7L Hemi rebuilt with forged rotating assembly for sustained high-load pulls
Reworked intake path fed by hood ram-air box; calibration aimed at repeatability over peak numbers
Upgraded cooling stack with high-capacity radiator and ducted airflow management
Flush side-exit exhaust behind the front wheels to reduce rear heat soak and keep plumbing short

Aero package

220mm-projection front splitter with outer dive planes and braced mounting points
Dual vertical radiator inlets plus auxiliary corner ducts for cooling and tire wake management
Hood: raised center ram-air box with triple slots plus twin rearward NACA heat extractors
Rear diffuser tunnels integrated into bed-cover extension with five vertical fins
Adjustable dual-element GT wing (1700mm span) on tall carbon pylons with endplate detailing

Chassis & stance

2009 Dodge Ram 1500 5.7 Hemi

Wheels & tires

Volk Racing TE37 SL forged: 20x11 front (ET15), 20x14 rear (ET5)
Toyo Proxes R888R: 305/35ZR20 front, 335/30ZR20 rear
Brembo big brake package: 6-piston front, 4-piston rear with slotted/drilled rotors
Widened track: +270mm front overall, +310mm rear overall to match flare coverage

Fabrication notes

Overfenders tied into a welded tube extension structure rather than relying on adhesive mounting
Splitter and dive planes designed around serviceable wear surfaces and replaceable edges
Bed-cover diffuser tunnels built as a composite assembly with reinforced fin bases to resist vibration
Ducting designed as sealed pathways (inlet-to-core and inlet-to-brake) to avoid “open-mouth” inefficiency
