Duck tail Weight?

[911st]

Anyone know how much a Duck Tail spoiler weighs. Reg or race weight?

[Flieger]

Aluminum frame original or fiberglass reproduction?

[911st]

Sure.

[911st]

On reflection, most interested in the fb reproduction. Still, would love to know the alloy or steel framed units.

[Scooter]

13.5 lbs. with grill.

I don't know exactly what my Getty repro duck weighs but I do know it weighs less than an OEM non spoiler engine lid.

[Fleming]

had to go to my notes for this:

Stock metal lid (with lid latch) 12.8 lbs.
Stock steel w/ metal grill, no hinges- Randy Webb- 15.8 lbs.

Fiberglass Ducktail over steel 10.99 lbs.

Aluminum lid 4.17 lbs.

Fiberglass (flat lid) Rennspeed says 4 lbs.

Sorry don't have the fiberglass ducktail weight

------------------------------
Rear center License panel:
Steel 5.3 lbs
Aluminum 1.8 lbs.

yup - that's what Rennspeed SAYS

BUT, in actual measurements on an accurate scale their flat FG lid weighed 7.5 lbs. !! And that was before all the patching and putty had to be added to it to make it fit properly.

I have lots of accurate data on various lid components - sing out if you want it posted here...

but don't have anything on ducktails as I decided to stay with a flat lid.

I guess what I want to know is a:

stock 85 lid.
stock 930 lid & spoiler,
stock Carrera lid with tee tray spoiler, and a
Ducky race weight lid/spoiler with stock hinge and latch;

-- what do they weigh and how do they differ in weight?

Then is there much worth chasing looking at the stock hinge, lifts, and latch?

[RWebb]

stock hinge, lifts, and latch are nil compared to putting a duck on much less a tea tray

you have to choose between weight and aero

another option is the neat disapeering 964 aero device - several have installed them on earlier cars

stock 85 lid should be same as my data posted above

[efhughes3]

My Duck was under 15, my old Carrera tail/lid with condenser was close to 50lbs.

[RWebb]

I could see that if you avoid the factory idea of a steel frame, etc.

Certainly, the a/c design is... suboptimal.

Stock 85 lid - dunno
stock 930 w/spoiler - 39# (well, OEM Turbo-Look = '86ish Turbo, not early)
Strock Carrerea w/ tea tray - dunno
Ducky race weigth - dunno
But, no name ducky w/ plastic grille - 15#

Weights via bathroom scale so, probably =/- a pound or so.

I concur with Webb. My fg ducktail weighed around 8 lbs. It's not a lot of weight savings over the factory steel; maybe a couple of lbs.

8 pounds sounds like a single layer pin-on type deck lid?

My 15 pounder is quite sturdy, is painted and has steel inserts for the latch/hinge attachment points. Oh yeah, it also has a Pelican and an IB.com grille badge.

While not much weight savings from a flat lid, there is about a 24 pound savings over the Turbo lid.

And, you do get a nice lift reduction with the duck vs. the flat lid.

So, for me, it's win-win. Now if I could just get the latch to latch.

"So, for me, it's win-win. Now if I could just get the latch to latch"

I assume the latch pin on the deck lid is centered and perpendicular to the latch plate in the closed or almost closed position. The latch mounting surface on the FG deck lid may not be square and should be shimmed accordingly.

Even with the factory steel lid (front or rear), many folks are baffled by the inability to secure the self-opening lid. I was too for awhile. I assumed the latch pin wasn't positioned far enough into the latch mechanism.

Look down into the latch area, then work the release lever back and forth. You'll observe a sweet spot where the mechanism narrows the opening and captures the latch pin on the deck lid. Any other lever position makes the opening larger. Adjust the cable locking screw so the mechanism is in the ideal capture position.

Disregard if you've tried this already.

Thanks. It seems to be centered and vertical and my working assumption was it wasn't going quite deep enough. I tried an extra washer between the deck lid and the latch pin plate and it didn't help. I'll try your suggestion on the morrow.

[carslutt]

i just got a all FG whale tail yesterday, it weights 10.5lbs w/ the screen installed in it.

I decided to try just one more time to get the plunger depth right using a tip from Dr. Gunter in this thread: http://forums.pelicanparts.com/porsche-911-technical-forum/372972-rear-decklid-mounting-any-alignment-tricks.html?posted=1#post4516228

Voila! It worked. Thanks to all.
