DP Motorsport Project Porsche 911 Sleeper Pictures, Pricing and Specs

I dont remember seeing this car? I remember a white one.

Anybody have any more details - how did they get the weight below 2000 lbs?

Got rid of lot of stuff:

Side rockers and rubber
Engine Seal Rubber, struts ( Maybe more )
Back Seats

Probably replaced allot of panels with plastic, maybe bumpers and bumper struts, etc etc.

looks great, serious weight loss though.. no idea how they got it that low

based on the article....

carbon fiber panels
metal supports drilled to swiss cheese, leaving only minimal structural stiffness
titanium exhaust
minimal interior
AC and heat removed
plastic and rubber bits removed
plexiglass windows

and of course... a "thin coating" of paint...:rolleyes:

But seriously.. titanium exhaust and carbon fiber panels will save you a lot of weight... that's probably at least 200+lbs?
lightweight seats... and other interior bits... another 150lbs?
comfort parts removed (heat, AC) another 100lbs?
glass and all the rubber and plastic bits... another 100lbs.?
finally cutting and drilling out extra metal.

Depending on carbon fiber usage... if you replaced all panels, gas tank, roof, and other components with carbon fiber... that would be a lot of weight.

Have a look here:

Text is in german but there are a lot pics of the build

They didn't. My guess that car weighs around 2,300lbs if it started as an '86 (maybe slightly less completely dry, as there's about 90lbs of fluid in these cars at half a tank).

Spec 911's can barely get to under 2,200lbs and there is absolutely nothing left of those cars. This one still retains a semblance of a street car

Shows the bumper blades are carbon fiber. That's pretty cool. Wouldn't mind having a set of those.

Isn't that with ballast?

The DP car is pretty much the same weight as mine, give or take a couple gallons of fuel.

Yeah if I remember right the following parts on the white car were CF - probably the same here:

Roof
Hood
engine cover
bumpers
front fenders
engine shroud and tin
Seats

more I cant remember

Wow that link to the German DP site is cool. That dash board set up looks really nice.

2,200 is the lightest I've seen on a post-74 car. I believe prior to that the tubs were about 200lbs lighter?????

Ballast on the Spec 911's is usually for lighter drivers.

My direct comparison would be my Carrera Spec/Spec 911 race car. Still has metal fenders/hood and rear quarters, but other than that there is not even a superfluous bolt in the car; literally nothing left to be lighted/removed without cutting into the tub (doors weigh 30 lbs together). That car weighs just under 2,300 with fluids.

I don't know, your cage is probably much more extensive than the DP car and the steel panels are still going to be quite heavy. My car could still loose a few more pounds.

Anyone has video's of this car with titanium exhaust?

Expensive pricing on the site for the lightweight materials :o

It's kind of killing the idea when you write "Sleeper" on the deck lid. Awesome car nonetheless!

Nice car and likely very quick with all that weight removed. But they could have saved a few more grams by cutting off the airbox cover... ;)

And I don't know, but with the rockers removed on impact bumper cars, in a profile view, they look like they're sucking in their gut.

First...Respect to people not doing backdates!

Would be more balanced with no front spoiler and a tad less rake. And yes, the "Sleeper" badge and boy racer fenders sticker don't seem in line with the cars title.

It does say in the article linked above that they got the car "a little less than 905 kg (about 2000 lbs)" ...

The power-to-weight ratio is dead on with a C5 Z06 Corvette.

Those cars moved pretty decent.

The site said they were getting around 270HP with ported heads, different cam but stock air meter. Doesn't that seem suspiciously high?
