"Backdate Dave" An icon redefined: the ultimate 911 backdate based on a Porsche 930 Turbo

Imagine the raw power of a Turbo Urelfer combined with the precision of modern racing technology and the elegance of handcrafted upholstery. The result is "Backdate Dave": a one-of-a-kind vehicle that has matured over 25 years of Porsche passion and is now ready to conquer the road. This vehicle has not simply been restored – it has been reinvented. In an uncompromising full-body restoration process, the car was dismantled down to the last screw and rebuilt with one goal in mind: to create the perfect Porsche.

The vehicle in detail

The heart of the matter: bittersweet 400 hp

The soul of this backdate is a masterfully modified 3.2-liter boxer engine. Nothing was left to chance here:

  • Performance setup: New pistons, cylinders, and camshafts form the foundation.
  • Turbo power: A specially tuned Garrett turbocharger combined with a custom-made exhaust system ensures brutal power delivery.
  • Control: A modified wastegate valve regulates the boost pressure up to 1.4 bar, generating a peak output of approximately 400 hp.

Chassis & dynamics: Precision without compromise
To bring this performance to the asphalt, the technology has been catapulted into the 21st century:

  • Öhlins suspension: A coilover suspension specially designed and tuned for this vehicle replaces the old torsion bar springs.
  • Chassis upgrade: Conversion to Unibal joints and reinforced stabilizers for razor-sharp handling.
  • Brakes: A massive RSR 6-piston brake system provides deceleration values on par with modern supercars.
  • Rims: Authentic 18" Braid Wheels, the first choice in rallying, underline the powerful appearance.

Interior & design:

A work of art by Justin Placek

The eye rides along. The interior was designed by renowned interior designer Justin Placek from Hamburg. Every seam, every material, and every detail was individually designed to create an atmosphere that combines luxury and heritage.

  • Exclusivity: Tailor-made details that are unparalleled in the Porsche world.
  • Lighting: Modern LED headlights guarantee perfect visibility at night without disturbing the classic silhouette.
  • Heritage look: The striking 100-liter tank with a central filler neck on the front hood is a nod to Porsche's long-distance legends.
  • Radio reception: Crystal-clear sound thanks to the DAB+ tuner, which ensures stable reception even on long journeys.

Condition & registration

  • Rebuild: Approximately 60% of all parts are new, the rest have been extensively restored without regard to cost.
  • Legality: All technical modifications have been officially approved. All expert reports are available, the vehicle has been inspected and is ready for immediate use.

"Backdate Dave" is more than just a car. It is a statement made of steel, leather, and pure adrenaline.
