IT ALL STARTED WITH A QUESTION...

DISCOVER GUNTHER WERKS

WHAT IF?

What if we could build the ultimate “money no object” 993?

 

Taking inspiration from the current RS range of cars and applying the same thought process & principles to the 993. Using modern day technology and applying it to the 993 making it better in every conceivable way, without detracting from the essence that is the pinnacle of air-cooled Porsches.

 

This is the question that inspired the team at Gunther Werks to produce the GW program for the 993 that we have now.

 

The GW 993 program was born, all from a single question…...What if?

 

From the outset, the GW 993 program would be focusing on uncompromised performance & meticulous attention to detail, the kind that Porsche aficionados would not only expect but indeed demand. Nothing but the best would suffice.

 

The 993 was the final evolution of a story that started right back in 1963 by Ferdinand Porsche himself, and the essence of that car had to remain intact, whilst at the same time every conceivable element of the car had to be improved upon.

 

The Porsche community does not take kindly to the molestation of an icon, the last of the breed revered by some as the last real 911.

 

The aim was simple, take the qualities and performance levels of today’s mighty RS models, and apply them to the air-cooled 993. Whilst the aim was simple the execution was far from simple.

 

Bringing the performance to a level that the factory engineers could only have dreamt about 30 years ago, whilst keeping the character of the legendry 993 intact would require a careful balancing act.

 

Utilizing modern day technology, that simply didn’t exist in the 90’s, Gunther Werks started their journey to redefine an Icon.

 

A Legend Was Reborn.

GUNTHER WERKS

“If I don't do a good job, I get out. I can't compromise” - Günter F. Wendt

 

Günter F. Wendt his official title was Pad Leader, a German American mechanical engineer who was noted for his work in the US spaceflight program, having worked on the Mercury, Gemini & the Apollo programs. He later went on to work on the space shuttle missions right up until he retired in 1989.

Known for his uncompromisingly strict approach and meticulous attention to detail in the pursuit of perfection, nothing was overlooked by Wendt, and as such he was welcomed by astronauts and earned him their respect.

It was this relentless principles of no compromise & perfection that mirrored our very own ethos that inspired our company name.

DESIGN & ENGINEERING

It was never about creating something that looked like it was imitating the past. It wasn’t about reminiscing about times gone by, it was about Imagining what could’ve been, had Porsche continued down the air-cooled route. We had to build the best driving air cooled 911 ever, one so pure and immersive in its driving experience, it would reward the driver like no other car could.

From the outset the GW 993 would always be a case of function over form.

 

Creating modern day solutions using modern technology and employing modern day production techniques to tackle historic & generic problems, all in the pursuit of perfection is what Gunther Werks is all about. All this done with a passion that did not distract from the ultimate goal, to deliver a driving experience like no other, & one that whilst modern, retained all the iconic elements the 993 is revered for.

To retain the qualities of the original 993 but to then modernize and enhance and improve would be no easy task.

The 993, like all air cooled 911s, was legendary for its steering feel, but was also famed for its inherent understeer. Through evolution modern Porsches still offer the famed steering feel but no longer suffer from the understeer that came with it.

This was the starting point, the single most defining element of any 911 and where the GW team would start.

In order to tackle this issue, we looked to Porsche and how they tackled the problem back in the 90’s on the most advanced 911’s of the time, the race cars.

The race cars used Porsche’s built in additional front suspension mounting points, these widened the front track to the same width as the rear track, making the car “square”. By squaring the car and implementing the racing suspension setups of the time it made the 90’s race cars handle like no rear engined car had any right to, and all but eliminated the dreaded understeer.

At GW we started from these additional suspension mounting points but using 21st century solutions to tackle 90’s issues. Bespoke GT style uprights designed to our own specific geometry requirements, from these uprights, custom wishbones were hung and used our own multi adjustable tie rods with full rose jointed components all the way giving us the solid base we wanted. This would then be repeated at the rear of the car, where we would then decide on wheel & tire combinations that would tie everything together, and make sure we had a car that drove right.

Working with the best names in the industry we made sure nothing would be compromised. Working with Pirelli to supply the tires we required, and with the experts at JRZ suspension that would make us the 4-way adjustable shocks and custom suspension components specifically for the GW 993 program. All of these had to work with the bespoke Brembo brake solutions that we would be running, including a carbon ceramic option that are massive 380mm front & rear. And these aren’t just any ceramics, these are Brembo CCMR’s, that use unidirectional carbon fiber construction utilizing Formula 1 technology.

Everything was considered, from the car specific suspension mounting points, to the wheel & tire sizes even the difference in sprung & unsprung weight from the donor car we would start with, nothing would be left to chance.

The end result of all this research, is a completely square track front & rear. Unheard of during the air-cooled Porsche era, but something that is common on the modern day cars.

They say power is nothing without control, so once we had designed the cars chassis, we could then focus on the power train. The same meticulous & exacting standards used on the chassis would also be applied to the power train. Working with famed engine builder Jeff Gamroth of Rothsport fame, the GW brief was simple: 4.0 Liters, Naturally Aspirated, air-cooled flat 6 with at least 400BHP, what we got was better 430 Plus BHP at 7800RPM, Jeff surpassed himself.

Running custom ITB’s, with GT3 type ecu controlled intake plenum, all controlled by a dual mapped Motec 600ECU into custom equal length headers leading to an ecu controlled GT3 rear exhaust, all driver operated by a dash mounted sport button, the engine can give you 400bhp of quiet cruising or at press of a button a snarling 425bhp of fury.

But again, it didn’t stop there, it wasn’t just about the power the engine would produce, but how we could get most of that power to the road that mattered. Continuing with the modern day solutions to address the old school tech ethos, and we started with the fan. The fan had not really evolved since the early air-cooled engines that could trace their roots back to the VW Beatle and the 912, so we went out to some Porsche enthusiasts that just happened to design jet turbine blades for aircraft engines as their day jobs. Using the latest technology, they came up with a lightweight fan optimized not only for maximum airflow, but also to reduce drag and power usage, they basically bought the design into the 21st century.

It didn’t stop there, the factory power steering pump, mounted to the engine in the rear and combined with its bracket, front to rear steering hoses and power steering fluid carried within them to the front mounted steering rack, all weighed in at around 70lbs. More importantly for us it used 25bhp from the crank. The same with the air conditioning, the weight of pump, pipes came in at around 60lbs, but more importantly for us used around 20bhp, so between them that’s a loss of 45bhp to the wheels & 130lbs extra weight.

Our solution was simple, we would design an electric hydraulic pump system for the power steering that would sit in the front of the car, and utilize an electric air conditioning system, again sitting at the front of the car. The result, we save 95lbs of weight, most of it from the back of the car, but more importantly both the aircon & power steering solutions would only use 7bhp.

The 38bhp saved would then be able to go through the 6 Speed G50 gearbox with our own specification ratios, single plate clutch and single plate lightened flywheel and onto the carbon clutched 40% locking LSD, to the 335/30/18 rear Pirelli Corsa’s.

Now the mechanicals were complete, we could focus to building the body of the car.

CRAFTMANSHIP

California has become the home to many of the world’s biggest automotive names, specifically to tap into the regions rich automotive design culture.  Our mastery of art and science was born in California, where respect for the past meets cutting edge research and development across a plethora of fields, and where automotive mythology comes to life every weekend.

Gunther Werks brings that past into the present. By combining state-of-the-art technology with all the conveniences of modern vehicles in a retro-designed package, every Gunther Werks creation exists among the most unique and versatile luxury sports cars ever built. 

 

Attention to detail and usability are at the forefront of what we stand for, so it comes as no surprise that every single aspect of the car was looked at. With the premise of saving weight by utilizing carbon fiber wherever we could, we started looking how we could “clothe” the chassis we had now created. 

 

Due to the chassis setup the car was now 6” wider front and back than the original, and any body modifications, whilst evolving the car had to remain sympathetic to the overall design of the legendary 993. 

 

Due to the cars shape, relying on just computers to do the job would not suffice, there had to be a human touch. So, we reached out to some of the best clay modelers in the industry, some that had worked on previous iconic cars from the same marque, who under our guidance went to create the shape of the GW 993. The car would need to flow, the important things like the wheel arch radiuses had to match the original, the way the front fenders and rear quarters flowed from the doors to both the front and rear had to be perfect, whilst also being functional. The front bumper had to look period correct whilst also being able to be functional and supply the additional cooling requirements for the new found performance, but most of all it had to all look as if it would have come from the factory, this was vital. Once the car had been clay modeled, it was 3D scanned so we could correct any of the imperfections and the car could be CFD analyzed for aerodynamic purposes. The data was analyzed, and once corrections were made the data was used to make the tooling for the carbon fiber panels.
 

Every body panel is made from pre preg carbon fiber, including the roof, for the sole purpose of making the car lighter. Weight saving measures that extend to the inside of the car, from our own lightweight carbon bucket seats, the carbon rear seat delete right to the carbon dashboard, all in the pursuit of weight savings.

 

The craftsmanship doesn’t stop there, the bespoke hand stitched leather work available in any color the customer chooses, the recessed roof in alcantara, the CNC aluminum vent controls and even down to our own in house designed LED headlights and taillights nothing is overlooked.
