A faithful recreation of Porsche's legendary 1955 550 Spyder race car, this replica is based on a Thunder Ranch Deluxe 550 Spyder kit delivered unbuilt to its original owner in Tennessee in 2009. It changed hands with another owner in Connecticut before it was purchased by the seller in 2017. The car was subsequently custom fabricated and built by hand using high-end parts from Fibersteel and Sierra Madre before it was completed in the Summer of 2020. It features a 1,914cc flat-four engine built by Jake Raby, a rebuilt transmission, heated bucket seats, a Brandwood cable shifter, Empi disc brakes, custom Porsche 914 gauges, a removable Plexiglas windscreen, cast aluminum Vintage 190 wheels, and more. This painstakingly built 550 Spyder replica is now being offered for auction by its seller out of Maryland.

Upon the seller’s purchase, the car’s 3” steel tube frame was extended about 15” inches to accommodate functional jack points. The rear frame is augmented by a removable drilled "K" member to match the original 550 frames, and the spare tire is mounted in a "seat" as the original. Period-correct Autopulse 500 fuel pumps were gutted and cosmetically restored with custom manifolds and brackets, then mounted on the aluminum rocker boxes, with the working Carter rotary pump plumbed in behind them. The VW Beetle fuel tank has been modified to put the filler 5" aft of those in most 550 replicas, to match the originals. A steel cover was crafted to give the appearance of the hand-hammered 24-gallon original tanks, held down with the correct steel straps. Brake cooling ducts were also fabricated and installed in front.

The car was finished in the Toyota color of Voodoo Blue in 2019 using two-stage paint with white darts and gold pinstripes under the clear coat. The underside of the hood is smoothed and painted, and the rear clam features operable turn-key latches, augmenting the usual remote pull latches. Locating pins are also present, as are the aluminum "Swiss cheese" reinforcement panel and ratcheting clam stay. The Fibersteel full-width plexiglass windscreen can be removed and replaced with a full-framed glass Speedster windshield. A tested, working wiper kit can then be affixed. The car also comes with a Beck Spyder top, which has never been fitted. It rides on Empi cast aluminum Vintage 190 wheels measuring 5.5”x15” at the rear and 4.5”x15” up front, with Vredestein Sprint Classic 165/80s on all four corners, purchased in 2019. The spare is a Federal in the same size but on a steel 4.5 x 15 Mangel wheel, date coded “2908”. The seller adds that some paint chips and swirls are present on the exterior as well as an imperfection in front of the hood fuel filler left from where the original hole was located.

The cockpit is paneled in aluminum, flanged, and riveted to resemble the authentic 550 Spyder. A floating wood floor was installed ahead of the bulkhead, and the parking brake handle was mounted to the left of the shifter as on the original. The seats were upholstered in beige Barberpole vinyl as were the firewall, rocker boxes, and insides of the doors. All of the interior vinyl is held by Velcro and can be removed in minutes according to the seller. Accessories include heated bucket seats, an ivory shift knob, pull switches, a three-position key switch, a push-button starter, a banjo-style steering wheel, custom offset foot pedals, a high beam foot switch, a dash-mounted rearview mirror and a reproduction, operable lever jack strapped in outboard of the passenger seat. The gauges were sourced from a Porsche 914 and reworked by North Hollywood Speedometer for a period-correct look.

Power comes from a 1,914cc Type 1 flat-four engine built by Jake Raby and sourced from Beck/Special Edition Speedster replica with a reported 1,200 miles driven. The engine features a balanced 69mm crank and 94mm bores, Bugpack 044 heads, an Engle w125 camshaft with .460 lift, heavy-duty rockers with steel pushrods, and dual Weber 44 carburetors including CB Performance hex bar linkage modified with heim joints to prevent wear. The engine is dressed in a Raby DTM fan shroud and includes a custom-made 547-style auxiliary breather and Accusump accumulator for pre-oiling. A spin-on filter is mounted on the torsion housing, plumbed with a braided hose and AN fittings to the pump. Exhaust headers collect at Magnaflow three-chamber mufflers and merge under the license plate. The rear wheels are driven through a rebuilt 4-speed manual VW Beetle transmission with a 3.44 ring and pinion, a .93 fourth gear, and a Brandwood cable shifter modified to resemble a 550 unit. Stopping power comes from Empi disc brakes with proper emergency brake cable fittings on the rear, covered by aluminum drum skins. The seller adds that the valves and carburetors were recently adjusted.

This sale will include owner’s manuals, a spare tire, full and half tonneau covers, a second windscreen, a wiper arm kit, a folding top, spare axle boots ignition software and adapter cables, extra valve covers and bails, a deck latch key, and a clean title.

The seller would like you to know: “I went down the 550 rabbit hole building this car, working to get the smallest details right. And by "right," I mean "not perfect." These were hand-built race cars, built to a high standard, which in 1955 meant stuff like the rolled vinyl wind blockers in the front door gap. There are hammer marks where the originals had them, rivets and screws lined up and spaced less than laser straight. And I built it to feel like a real one:  The top speed of each gear is very close—sometimes exactly—to what the original cars had. It was built to be driven.”

    OK folks, last day. I’ll be at work mostly but I’ll keep an eye out for any last minute questions.

  • EVantage (registered bidder) 1 monthago

    I have the Vintage Speedster cousin of this car in similar colors with similar motor and freeway flyer transaxle. Quite a head turner in those colors. This seems like a really nice one. At Cars and Coffee or just the local market, everyone needs to come say hello, tell you about their uncle or dad’s Porsche, and ask “is it real?” I don’t think it matters, except to your accountant. The driving experience is priceless.

    Rolled the Spyder to cars & coffee yesterday. New photo is the typical situation.

  • eericson (seller) 1 month, 1 weekago

    @jab7106 Not sure; can't find the codes on the outside. I bought them from Tire Rack in April of 2019.

  • jab7106 (registered bidder) 1 month, 1 weekago

    What are the date codes on the tires??

  • eericson (seller) 1 month, 1 weekago

    @RDC3500GT Thank you for those kind words.

  • RDC3500GT (registered bidder) 1 month, 1 weekago

    WOW!! Having myself modified a Thunder Ranch Spyder to try to achieve what is pictured here - I can tell you: this labor of love is REALLY well done. This stands out from every other recreation Spyder out there and will make even the experts take a second look. From the barber-pole vinyl seats to the correct rocker panel bracing in the foot wells, this car is as dead-nuts on as I've seen. Well done and GLWTA!!

  • eericson (seller) 1 month, 1 weekago

    I uploaded a few photos of the undercarriage and some with the interior vinyl stripped out.

  • eericson (seller) 1 month, 1 weekago

    @Whatever123 Fiberglass body. Weber carbs.

  • Whatever123 (registered bidder) 1 month, 1 weekago

    Is the main body fiberglass? Are the carbs solex's?

  • ALB 1 month, 1 weekago

    Wow- I watched this car being built (through the magic of the internet) and the seller's amount of detail in replicating original design features of a mid '50's Spyder is amazing. Someone is getting a Spyder like no other! GLWTA

  • eericson (seller) 1 month, 1 weekago

    @Whatever123 the engine is one of a series Raby built for Beck/Special Edition in the mid 2000s. I've seen the dyno sheets for several of them, I'm told they all made about 120 hp (usually a little more) at 5500 and spun strong over 6000, with best torque at 4000, usually about 125 lb-ft or so. Unfortunately I do not have the slip for this particular motor. Driving vid is in editing now and will upload asap.

    @mppickett Mostly Googling but I owe a huge debt to Andrew Hosking at Type550.com, and Rainer Cooney of The Spyder Factory, both of who studied real ones up close and put a tremendous about of knowledge online where someone could find it.

  • mppickett 1 month, 1 weekago

    Wow, amazing attention to detail. How in the world did you figure out what the originals were like?

  • eericson (seller) 1 month, 1 weekago

    @Joevant Thank you! And thank you for bidding.

    Wow what a stunner!! I had a Beck 550 I daily drove in Hawaii for years. It was a truly magical time and unforgettable driving experience. This car looks beautifully put together and I love the color combination. GLWTA

    Hello everyone. Thanks for checking my auction. I built the car and am familiar with all its features and foibles. I'll be monitoring the comments and responding to any questions.
