Porsche 935 DP

DP, to the best of my limited knowledge, is an aftermarket German Porsche tuner. I've seen their ads for rims, Turbo oil coolers, and a few other cool bolt-on stuff from Porsche mags. Perhaps this product line is a 'spin-off' from a racing department, I dunno....how old is the car?

On a side note, anyone know anything about Kramer turbo Porsches?

 

dp was or still is a company named design plastics . Thats abot all i remember about them .

 

they were similar to kremer in that they modded up porsches to race but made the name in producing 935's for the street. they were nicely turned out street versions of the 935 race car and were and still are very, very fast. they are a little like ruf in that full "factory" turned out cars carried a dp serial number and are pretty valuable to the right buyer.

they are also like ruf in that you can buy most or all of the dp parts individually and upgrade your car on your own...these cars are not to be considered as valuable thus it is important to determine if the car is a factory build or a component car. in any case...they are a very nice machine but unless you really need "dp" stamped all over the car...you can do more w/ less and buy a stock or modded 930 and throw some dollars at it.

the 930 may be the best all around sports car ever on the planet.

 

Kremer was like DP an aftermarket German tuner and was quite successful in racing modified 935s, 956s and 962s. I worked for H&M motorsports in the late 80s while they were one the the US Kremer dealers.

 

When I was growing up, a guy down the street had a real DP Porsche. I remember taking a look inside and seeing the adjustable boost controller and cage. Very cool street car. I seen him get on it a few times, an absolute rocket. One of the most unique features were the wheels which actually stuck out fron the tire in the center for brake cooling. Alwasy loved the look of them. Maybe someone has a photo.

The search function is your friend. But, I'll shorten it down: The discussion topic below was dealing with the perception of aftermarket fiberglass slope conversions being inferior to the factory steel ones http://www.ferrarichat.com/forum/showthread.php?t=78577&page=5&highlight=DP+935


The first road going slant nose 930 were first rolled out by DP Motorsports (Design Plastics). DP was part of a hand full of tuners such as RUF, Gemballa and Rinspeed that you could take your Porsche to and have anything you’d like done to it. Just as you could take your Daytona coupe to Starman to be made into a spyder you could have DP make your 930 into a 930 slope nose. Now these DP cars were a good deal different to the car on Ebay, but I’ll get to that in a minute. The major thing to deal with hear is the absolute complete misconception that you’d take a “chainsaw” to a 930 in order to make it a slope nose. The only things you have to do are unbolt the two front right and left fenders, bolt on the new slope fenders. No cutting involved. The pop up head lamps and motors will be installed onto the fenders and front unibody sides. The factory used the same general mechanism that was used on the 924/944 pop up lights. Many of the aftermarket slope nose kits (steel or fiberglass) used the Mazda RX7 pop up motors and headlamp gear. They were widely available, inexpensive and reliable. The front spoiler could be kept stock or you could unbolt it and bolt in a new one like the Ebay car has. Once again, no chain saw. The side rockers are unbolted and full rockers extending out to the edge of the rear wheel flare are bolted on. Again no chain saw. The tail can stay the same or you can unbolt the rear engine cover and bolt on a larger aftermarket one if you’d like to run with a larger intercooler. No chainsaw. This brings us to the only point you have to cut into the body. On the front of the rear wheel flares you have to cut the metal in order to put the vents in. This was done on BOTH aftermarket kits AND FACTORY 930 SLOPE MODELS! The vent inserts are welded in and supply air to help cool the rear brakes and the engine. On factory models the right rear had an oil cooler placed in it. Unless it was a Carrera slope nose (a non turbo slope nose) in which case the oil cooler was in a vertical placement in the front chin spoiler.

So in reality the only difference between the factory and aftermarket kits is who made the body pieces and who installed them. The installation procedure was the same whether it was the factory or someone else.

Now back to your history lesson. DP was a maker of competition bodywork; most specifically for Kremmer. Any Kremmer racing 935 had DP body work on it. So if you’d purchased a road going DP you not only would have the bodywork created by and installed by the same guys who’d made the 935s you also could get Kremmer to tweak the engine for extra HP. DP did all of the above to the bodywork and they also enlarged the rear flares to take much, much larger wheels and tires. They would use either fiberglass or if you had deep pockets carbon Kevlar. Which back in the late 1970s and early 1980s was much, much more exotic than having a body made of carbon fiber today. At that time only a select F1 teams were using carbon fiber or carbon Kevlar. (See the attachment for more on DP Motorsport).

Then in 1981 Porsche had enough people asking them and seeing the money being lost to tuners, opened the Sonderwunsch (special wish) programme repair department.* Notice that repair department bit. That’s because your 930 was pulled off of the assembly line just before completion and rolled into the factory body shop where the transformation outlined above took place. IN A BODY SHOP, NOT ON THE ASSEMBLY LINE. This conversion was known as a Flachtbau. You could get anything you wanted through special wish. Want a nice wood grain dash, all white interior with white face dials? No problem, just pay the man and it was done. Do you want your new Porsche color to match your wife’s favorite lipstick? Not a problem send the lipstick over it’ll be matched, thank you now pay the man. The 930S option became an “official” option in 1986 and you could actually run down to your local Porsche dealer and buy one off the floor. At Forest Lane Porsche Audi in Dallas (the largest Porsche dealer during the late 80s) you could go down just about any day of the week and there would at least be a 930 if not a 930S in the showroom. It was a veritable candy land for someone like me.

So, what’s the difference in conversions? Functionally they’re all the same. The air they’re plowing through doesn’t know the difference between fiberglass or steel or who it was installed by. The elimination of the headlamp bulges reduces drag by a good bit and (if memory serves me correctly) increases front end down force by as much as 30%. That’s a lot. With a fiberglass conversion you do get better performance. It’s lighter than the steel and that means the power to weight ratio on the car improves so you get better acceleration. Down side is paint finish isn’t always as good and in the event of an accident repair bills could get expensive. And for some reason a lot of people like yourself frown down on any kind of fiberglass body panels. Even though almost all purpose built Porsche race cars of the late 60s and early 70s were primarily made out of fiberglass (904, 908, 917 etc) as was all of the bodywork of the racing 934s, 935s, 956s, and most 962s(I believe carbon Kevlar was also a bodywork component on these cars). Well, with the DP conversion you’re going to have to really shell out some cash because they’re worth more than even the factory conversions. You can still find them on the cheap but drivers as well as collectors seem to love them. http://www.dp935registry.com/index.php?page=registry

AWSOME.....I passed on a factory slopenose turbo cabriolet when I was searching for a 328 a few years ago, but I've always had a soft spot for slopenose 911 turbos. I saw (rather, HEARD) a Kremer Turbo car once in my life. I've never forgotten it.

 

was driving thru beverly hills in 1980's on vacation when startled by loud engine noise behind gated mansion. gates opened and rod stewart flew out in his dp935. was a cool moment at the time for a car guy and rod stewart fan.
