President’s Corner Dan Doyle - President

Hello, everyone!!

I hope you all had a wonderful 4th of July with family and friends!

As well, the 63rd Annual Porsche Parade in Lake of the Ozarks, Missouri occurred on July 8-14. We had several members who were lucky enough to attend. Please stay tuned as we’ve asked these members to write articles for the Kassette. Their experiences at Parade should be fascinating reading and should wet your appetite as the Parade next year is in Boca Raton,

Florida. For most of you (including me!) this will be the closest Parade to our Region in terms of geographic location in recent years. Don’t miss it!!!

As for the rest of the month, well, it’s August. It’s hot. It’s muggy. Stay hydrated and cool!!!

As usual, Porsches & Pancakes is on the first Saturday of the month. Please take the time to join other Porsche fans and talk about your favorite subjects: your car and Porsche! Also, we have our Thursday

August 2018

Say It Ain’t So! Geesh. Two thirds of a page in The New York Times under the headline “Classic Car Museums Are Losing Much of Their Luster.” It’s another sad day for gear heads.

Exhibit A is the Auto Collections at the Linq Hotel @ Casino in Las Vegas, which was formerly known as the Imperial Palace Hotel. Have you been there?

The space consumes virtually the entire fifth floor of the hotel, and it has for the last 40 years. Up until 1999, the venue hosted the personal collection of hotel owner Ralph Englestad. That’s when Don Williams took over the space, showcasing some 150 to 200 cars at a time. He got it rent-free, in exchange for the hotel pocketing ticket and merchandising revenue.

The article quotes Rob Williams, Don’s son, sitting at a “wooden desk on one end of 125,000 square feet of emptiness.”

“I can’t wait to close the door and walk away. I don’t want to remember this place like this,” he says. In its prime, the space hosted some 3,500 visitors a day, making it one of the most popular daytime attractions in Sin City. By the end, according to Williams, attendance was down to fewer than 1,000 per day.

The museum closed its doors last New Year’s Eve. And most of the cars were auctioned off.

Hostetler’s Hudson Auto Museum in Shipshewana, Ind came to the same fate on the same day. A year earlier, the Walter P. Chrysler Museum, on the campus of Fiat Chrysler outside Detroit, was shuttered. And, a few months before that, the Riverside International Automotive Museum, the last physical remembrance of that once-fabled track, also bit the dust.

What’s going on? According to the Times article, Kurt Ernst, editor of the classic-car news site Hemmings Daily, included the following in his five predictions for 2018. “Expect to see more museums close and more collections head to auction,” he said. And Ernst added, “If you have a favorite museum, 2018 will be a good year to pay it a visit, or better yet, make a cash donation.”

Then there’s Matt Anderson, a curator at the Henry Ford Museum of American Innovation in Dearborn, MI, and president of the National Association of Automobile Museums. He says in the Times article that his members are “struggling with this realization that younger folks aren’t into cars the way their parents and grandparents were.”

But wait. There are some rays of sunshine. Take the Indy 500 Museum in Indianapolis. The Shelby American Museum in Boulder. The Petersen Automotive Museum in Los Angeles, which underwent a $180 million renovation, before reopening in 2015 as a glittering car palace.

Or the Gilmore Car Museum in Hickory Corners, MI, which lets visitors take lessons on driving a vintage Model T. The catch? You have to book ahead. And the Simeone Foundation Automotive Museum in Philadelphia, which hosts twice-monthly “demonstration days.”

What’s different at these facilities?

According to the article in The Times, these venues have tried to offer “unusual experiences and a different mix of wares.”

Although, whether this works long-term, is anybody’s guess.

I’ve tried to help it along. For Father’s

by Danielle Badler

Day last year I got my daughter and son-in-law a family membership at the Petersen, which is close to where they live. They take my two grandsons, almost four years old and one, to see the “cool cars” on a regular basis. To spur interest, every time I visit I bring along Tonka toys for them to play with, mostly of Porsches.

And we practice saying “PorSHA.” So, to a certain extent at least, there’s still a lot of interest out there, among young and old. Car shows abound, as do Cars and Coffee get-togethers. My daughter informed me that, for Father’s Day this year, they took the boys to Rodeo Drive for the annual display of exotics.

But I wonder whether this will be sustained. Will my grandsons ever actually drive a car, by the time they come of age?

Will they care? I don’t know. I just hope I’ll be around to find out.

According to the Times story, museum closings are not entirely doom and gloom.

Kevin Biebel, chair of the Saratoga Auto Museum, says that these shutdowns often mean the cars are going to new collectors.

“They’re not going to the crusher,” Biebel notes. “They’re not getting turned into soda cans…. They might not be that tourist attraction, but they might very well be the next making of another car collection.”

I sure hope so. Although it sounds like the cars won’t exactly be open to public enjoyment. Rather, they could very well be locked up tight in private warehouses, only to see the light of day at special events and at specialized car shows.

Oh well. It’s better than scrap iron, I guess. I have my memories and I’ll cherish them always.

Gold Coast Region is very lucky to have several historical car collections that provide our members access during club tours that are setup by our event committee. Most of these tours fill up quickly so sign up as soon as the they are opened for registration. Most of the events are done in a drive and dine format, so don’t miss the fun and support our event sponsors that open their doors to our members. On the right are a few of the locations that we visit.

From the Members Last month, Wayne Overton brought his recently restored 1975, 911S Targa to the Stuart Diner for its first showing at Porsches & Pancakes. To honor 25 years of Stuttgart production, Porsche issued a limited edition Silver Anniversary 911S in 1975. Only 1500 were built, with half going stateside. This car is #204 and was purchased in California 22 years ago. Two years ago, Wayne began a major update with complete rebuilt engine and transmission, new paint and interior.

16

Die Porsche

Each car wore diamond-silver metallic paint and sported a numbered dash plaque with Ferry Porsches facsimile signature.

The custom interior trim was a woven silver and navy tweed. Wayne spent hours of research on the internet to source the fabric for his car. The Anniversary edition was the only car that had that fabric, so it was important to find the correct one. He sorted through many threads on forums, and finally found Cartex in Germany.

by Pat Timeyer At first, there was a language barrier, but with “Google translate” they worked their way through it. Wayne had them make the front seat covers, and when they arrived, they were perfect. He then ordered the fabric and vinyl to have the rest of the car completed here in Stuart at Lane’s Trim Shop.

Tech Corner :

Fuel Injection Article by Pedro P. Bonilla, Tech Editor

We all know that our beloved Porsche engines need air and gas to produce power, but how do the two come together since one comes from the outside and the other from the tank?

The first question is what year Porsche?

And that’s because throughout the years there’s been continuous development in the way that gasoline is delivered to the engine and how it’s mixed with the incoming air.

The air delivery is pretty basic. Outside air is sucked into the intake box, passes through a filter to make sure that it’s clean, passes through the carburetor (early cars) or the throttle body (later cars) and then gets directed to the cylinders though the intake plenum manifolds. On naturally aspirated engines, the engine itself sucks in the air. On forced induction engines, the air is compressed or charged before it gets to the cylinders.

On the very first Porsches, 1948 – 1974*, air was pulled in, as described, and the carburetor would be responsible for providing the metered gas. Liquid gasoline does not ignite; only it’s vapors in the presence of oxygen, so carburetors use a set of jets to atomize the liquid gasoline in order for it to mix with the incoming air. These older engines used a completely mechanical system to try to obtain the optimal mix ratio (air - fuel) of 14.7:1 otherwise known as the stoichiometric point. (*) Mechanical fuel injection was introduced for the first time in a Porsche in 1969, but it did not become standard until 1974, then evolving to digital management in 1984.

Die Porsche

Kassette | August

2018

As more efficiency in the engines was required, mostly to make more HP for racecars, better ways of mixing air and gas were developed. The next step after the carburetor was fuel injection.

The earliest and most basic type of fuel injection is the singlepoint. It simply replaces the carburetor with a fuel injector nozzle in the throttle body which is where the air inlet (butterfly) valve is located. Though not as precise as the evolutions that followed, throttle body injection (TBI) meters fuel with much better control than the carburetor it replaced.

But in 1969 Porsche chose to use the newly developed Bosch Jetronic System, which injected fuel into a port just above each intake valve. This system was widely used until the mid 70s.

The injectors were all interconnected by a pressurized fuel line known as the fuel rail and dispensed fuel by opening and closing at precise times throughout the engine’s cycle. Nominal fuel pressure in the rail is about 3.5 BAR or 50 psi. When more air was given by the driver when the accelerator was depressed, the Jetronic system answered by keeping the injectors open a bit longer by lengthening the pulse-width of the ground signal to the injector and thus obtaining the perfect mix (14.7:1). Typical fuel injector pulsewidths can be as little as 1.5 – 2.0 milliseconds (ms, or thousandths of a second) to over 20 ms at higher RPMs and loads. The positive terminals of the fuel injectors are always supplied with voltage, as long as the ignition is on. The switchable ground-path which completes the electrical circuit is controlled by a transistor in the electronic control unit (ECU).

Porsche has maintained their relationship with Bosch throughout the years and therefore has implemented most of their versions of fuel injection technologies, modified for the particular needs of the current Porsches at the time.

D-Jetronic was introduced in the four cylinder 914 because it was more than adequate for low-revving engines such as the VW Type IV used in the 914s which used a single throttle body and individual fuel injectors for each of the four cylinders. This system proved to be prone to mechanical wear and therefore inaccuracy in the mix so it was not used in the 6-cylinder 914s.

The next version was the L-Jetronic which used a mechanical airflow meter for the first time to determine the amount of fuel metered into the cylinders. This version was applied to the 1.8L 914s (1974 – 1976 ).

Measuring the amount of air proved to be much more efficient that the previous arrangements and determined the direction of further development.

In 1983 Porsche used the Bosch Motronic System which integrated the electronic ignition timing control and the fuel control into a single control unit. From that point on, both Porsche and Bosch refer to this unit as the DME (digital motor electronics) instead of the ECU (engine control unit), although you may see it used indistinctly even today. The first offering of the DME came in the 944 with the 928 and 911 following closely behind in 1984. This system required very precise measurement of engine speed and position, so various engine component position sensors were introduced (crankshaft, camshaft and flywheel). On later versions, oxygen sensors were also integrated into Porsche’s Motronic Systems to obtain better catalytic converter function and to also correct excessive lean or rich conditions.

Many more developments were introduced into the Motronic Systems as time went by, such as onboard diagnostics (OBD), hot-wire mass airflow sensors (MAF) in the 32-valve 928, new onboard diagnostics (OBD-II) in model year 1996, additional oxygen sensors downstream of the cats, VarioCam technology (1997 Boxster and 1999 and Carrera), electronic throttle control (drive-by-wire in the 1999 Carrera and 2000 Boxster) but the fuel injectors remained basically unchanged for 40 years… … until Direct Fuel Injection first appeared in a production Porsche in with the introduction of the new 9A1 engine of the 997.2 in model year 2009. As the name implies, fuel is injected directly into the combustion chamber, leaving just air being fed though the intake manifold. Injecting fuel directly into the cylin-

ders (at pressures close to 2,000 psi) offers better homogeneity of the air-fuel mix.

Because DFI can inject the fuel closer to the source of ignition (spark plugs), it produces a more even explosion in the cylinders.

The fuel mixture is therefore burnt more completely, increasing efficiency, reducing emissions and improving power.

But it’s not just benefits that DFI brings to modern cars. There have been a few issues.

Because of the extremely high fuel pressure needed to operate, fuel pumps have been not-so-reliable although getting better.

Another issue inherent to DFI is that because only air now flows through the intake valves, carbon deposits that were previously washed off by the gas-air mix now tend to create deposits on the valves.

It’s ironic that Porsche and other manufacturers introduced “new” DFI technology in 2009 when Mercedes Benz had used it and discontinued it in the 50s. My Dad’s 1957 300SL had DFI and he was always complaining about carbon deposits in the intake valves.

Like the old saying: Old is new again!
