Whale Tail vs. Tea Tray Spoiler

New to this forum so forgive me if this has been covered before. What is the difference between these two spoilers. When where they intorduced, and on what production cars. Thanks

The whale tail looks a lot like a whale tail. Looking from the side, there's not much depth to it. The tea tray spoiler is what you find on all intercooled Turbos. In profile it's deep so that the intercooler fits inside.

They started on the 930
(whale tail ) 1975-1977 they where low no intercooler
(Tea tray tail) 1978-1989 they where raised higher too fit the intercooler
Also on the 964 1990-1994
I think that's all there was

This is my understanding:

Whale tail (which looks like the very early Carrera tail), offered on the early 930s:



Tea tray (aka sushi tray), offered on the later 930s. Note the vertical rubber lip "end plates" on either side (left/right) of the tail:



Carrera tail:



Actually, technically these aren't tails but rather spoilers, I think.

And will a 930 tea tray fit on a 911 converted to 911SC?

One thing worth mentioning, for people interested in this sort of thing, is that the tea tray (denoted as the "3.3 Turbo" in the following, rear axle graph) outperforms the whale tail ("Turbo") in lift reduction.

Yes, it is worth noting, these are not down force spoilers as seen on the GT3. The shape of the 911, as they got faster, acted like an aircraft wing. So it is inducing lift at the trailing edge - over the engine bay - where the airflow tends to separate from the body. The spoiler breaks this pattern up, so decreases the lift, rather than adding downforce.

Noah930's pictures are correct distinguishing the early 3.0L 930 whale tail, 3.3L 930 tea tray, and SC tails.

The early Carrera tail referred to above is also of the whale tail variety. These were fitted on 2.7 Carreras in 1975-76.


The 3.0 Carreras in 1976-77 had yet another version of the whale tail with different profile rubber lip as the 2.7 Carreras.

This first pic of the silver car is a tea tray lip fitted to a early Carrera/turbo deck lid and is not correct. Notice the angle of the silver lid transition on the sides to the black rubber lip does not match, yet on the early lip it does. The later lid does not have this transition. This deck should have the early whale tail rubber lip. The reason behind the redesign of the lid was to accommodate the 3.3 turbo intercooler which does not fit in the early whale tail lid with the downsloping grill.

One other point to mention, is I think I read somewhere that you should not install either tail without also installing the lip spoiler ( or something similar) as the tail is designed to work with a front spoiler, and negative lift is increased in the front when using tail and no front spoiler....

I recently put a Carrera Tail and ditched my tea tray. It wasn't a perfect fit but close enough for me. You can watch the install if you're interested here: https://www.youtube.com/watch?v=EUcajCjfMzU&t=8s

My SC has the whale tail as per factory. It seems it must have been optional. I have spoken to a guy that had same yr SC without a tail. Said the car got very nervous at speeds around 80+mph. He got nervous too. Mine is totally planted at any speed. In fact it feels and handles much better at 80+ mph than lower speeds. Comes alive and well balanced.

My US '82 SC targa had a tea tray (turbo 3.3 looking) tail as a factory option. It looked like the same tail on my '86 Turbo but I have no idea if they were dimensionally identical. Car handled just fine well in excess of 100mph (once I put decent tyres and had a proper alignment done).
