crags' rather old, rather orange 911
Discussion
right, starting with a couple from last month, this was us viewing the car in the museum it was being stored in...
& then after leaving it with nick moss at early 911 for it's session with the spoiler fixing machines
the start of the long drive home, which resulted in a much needed beer afterwards

What a stunning 911.
For me it hit perfection before the duckbill rear spoiler. I prefer the lines without it, seemed to show off those arches a little better. But what a lovely car. You must be over the moon.
totally understand on the ducktail, some do think it's an adittion the car didn't need but the reasons i picked it for make it the choice for me.For me it hit perfection before the duckbill rear spoiler.

basically when you look at a 911 in profile the car is shaped like one big wing, this means that there is some lift created when driving, noticeable above say 80mph & particulary so into 3 figures.
to compound this problem it also makes the car pretty vunerable to cross winds at motorway speeds.
the effect of the ducktail, & indeed most 911 "spoilers" is to do just that, spoil the air low over the top flow of the wing, in this case the cars roof/rear screen. a ducktail does this perfectly (in fact there is a graph done by paul frere when at porsche that show the effects on lift of the ducktail, & whaletail that was also fitted), although to some to the detrement of style-or the classic 911 shape if you want. this is in conjunction with the front lip i've had fitted to lessen the air going under the car.
of course you could say that porsche themselves solved this themselves with the introduction of the retractable spoiler on the 964 series car & in fact some people do fit the retractable lids on the earlier cars & i can see why people like them-clean lines when stationary & reduced lift where you need it above 70mph.
however, me personally, i feel that with these spoilers, although you do get the reduction in lift you unfortunatly get a load of weight exactly where you don't want it on a 911-on it's arse!
the 80's whaletails are the same-they actually reduce lift by more than the ducktail but they also weigh a bloomin ton! so (if you're still awake)
flat back lid-produces lift across both axles
ducktail-reduces lift & weighs less
whaletail-reduces lift but weighs more
retractable spoiler-as above.
of course, none of this is really that important as the main reason i fitted the duck as because i love the look of it but it is nice to be able to baffle people with science
though to be fair the car did have a new front valance fitted, & it had the mounting holes for the front lip in it already. the rear lid has been kept along with all fixings so if i or the next owner want to revert back to the flat back look it won't be much a of a job.Beefmeister said:
Gorgeous.I would consider some period black P O R S C H E lettering either on the front or rear face of the ducktail too, that would look ace.
that does look fantastic beefmeister-like this below?
the onlything is i have the red reflector on my car & that has the porsche script across it:
(might be just visible in this photo)
i think it might look a bit daft repeating it. i do want to badge it up somehow though? any ideas fella's? this is the orig 911SC badge (with turbo tea tray spoiler):
not that i want to pour scorn on porsches design but i always just thought it a bit of a naff badge for some reason?
Love the car having seen it on IB, I think the script on the green car is perfect, it's what I was going to do if I stuck a ducktail on mine, Im still undecided though!
It's all about IB 911's, I soooo want my car to be your colour or viper green! Can't afford a full colour change though and might even have to sell the car soon to fund a house

Well I don't think mentioning that on this thread may be such a bad move 
& your car has generated some grate comments on the impact bumper thread in the Porsche section either. Lovely car mate, such a shame to have to move it on, I was actually going to use a picture of your car in a post showing the perfect flat back look.I don't think I'd worry too much about the colour either-looks great in the classic White with red script
