Hey guys, what about wings? Over the years, I've seen less than a handful of euro Downdraft cars with the low big-wing whereas I've always seen the smaller wing on the FI cars. Did a few European owners simply fit the old wing later? I know there was a change in source, but does anyone know if any big wings left the factory on cars bound for North America?
Which itself is not easy to get. Wings are not an exact science with Countachs primarily because in the beginning, the unit was a sperimantale application developed by Giampaolo Dallara for Walter Wolf's cars, one which Autpmobili Lamborghini SpA never Homologated with the Italian transportation or any other. As such, it's unofficial application led to a number of different versions from big to small over the course of production, and, many cars started off with wings which were later removed, and vice versa. To answer your specific questions: - Yes, some European owners fitted the big wing later, but many European cars came with it anyway, that said, some Eurpean owners fitted the small wing also. - No, USA Fuelies came with the small wing, however, there were some Downdrafts that left the factory bound for the North America under the auspices of the erstwhile Lamborghini concessionaire Joe Nastasi that had the big wing affixed.

Thanks for that info. Do you know how the differing wings have traditionally held up over the years, one vs. the other? ...considering the "bubbling" wing skins and trapped moisture problems, etc.
TBH I have heard of all the different wing variants having problems randomly, some people swear they hold up just fine, others have so many problems they end up throwing the unit away. I do remember that I owned a totally original LP400S S1 with all original paint and the wing was still perfect, but I'm afraid my feedback is a bit inconclusive on this.
Neither my first 87 QV nor this one seems to have any issues with bubbling. But Ive seen some where its very bad.
I looked for this earlier, here's an informative thread about the different wings, related issues, solutions & more https://www.ferrarichat.com/forum/threads/countach-rear-wing-corrosion.368554/
Wondered if anyone knew how the inner 2 rear bumpers are mounted on US models? I've seen some cars where the outer 2 bumpers appear to have been removed (and I believe those involve body work which appears to be complete) but I'm unsure how the inner two are mounted - are they easier to remove or do they still involve body work? They appear to mount above the exhaust, hence I wondered if they can be more easily removed?
The attachment brackets are welded directly to tubular frame as shown in the parts manual for the USA cars. The bumperette’s bolt directly onto them. Mike Image Unavailable, Please Login
Thanks Mike - can I ask where you found that image? I tried looking at the Eurospares site to get some diagrams but didn't find anything as useful.
Image Unavailable, Please Login This should be an interesting wintertime project....... rebuild kits for the Bosch fuel distributors and warmup regulators. Mike
Thanks Mike - can I ask where you found that image? It is a Feb of 1986 page. If you go to my web site, Lamborghinionly.com and click on Downloads, then Factory Manuals. Then scroll down to 83-88.5(parts PDF format). Then when you get there select 86 5000QV Inj Tav1-15 pdf. Will take a minute or so to load as it is around 24 mb long. You then can scroll down to the page you want showing the frame.
Are those rebuilds something an averagely competent person could do or do they require technical knowledge?
I think that anyone mechanically competent can carry out this operation. I do know that once you start messing with the plunger and some of the internal components they do need to be set up properly. But, just to replace the O-rings and seals should be pretty straightforward. Here is a short video I found on YouTube that shows a rudimentary idea of what the insides of the fuel distributor look like. Mike
This looks like fun, and I feel sure you have above-average mechanical skill or prior experience with this Bosch Fuelie system, perhaps that's why you're comfortable attempting the rebuilds yourself. That said, I agree the concept is pretty straightforward. However, per Dean's concern, we all know that most things do not go according to plan in the maintenance of a 32-year-old classic car, issues are often encountered that require experienced remedy, accordingly, for that and for the safe & effective running of the car, I would highly recommend that most owners send the car to someone who is actually very experienced with this particular Bosch Fuelie system. I'm sure that would be prudent advice.
Good points Joe. I've done a few mechanical things in the past (replaced fuel pumps, clutches, transmissions, rebuilt basic carburetors etc.) but there are some tasks that require specialist knowledge. As Mike pointed out, replacing seals and O-rings is pretty easy - but when it comes to more specific things that have to be tuned or calibrated, they're best left to a specialist. I'm just interested to know what maintenance tasks can easily be handled by someone with basic skills.
Image Unavailable, Please Login For sure. There are a couple places that are very competent in rebuilding this units. Places like K-Jet in Australia or CIS Flowtech in Alabama. There is also DeLorean Auto Parts in Houston that will sell you rebuilt units when you send in your core. The most tedious part is getting each each cylinder to provide the same quantity of fuel. You really need the Bosch KDJE-P 200 (also identified by its newer part number KDJE-7451) for that. I tried to find a used one, but they are few and far between. I’ve even contacted bosh and they told me they no longer produce them. I’ve even contacted Bosch and they told me they no longer produce them. Attached is a photo of this unit. Also, the Ferrari 400i page has a wealth of information and rebuild tips: http://www.ferrari400parts.com/ferrari400.php I see Auto Tool has a product that they claim will function like the KDJE unit.... just not ready to drop close to $500 until I know for sure.

Historically 3m Body Schutz is used universally on all cars. Note it takes a special spray gun to apply, but it shouldn't be too expensive to purchase. Most automovtive paint stores have it. In the past I have purchased it at Scottsdale Paint. Cheers Jim
An easy way to test for even distribution is set up the system on a bench and put each of the fuel nozzles in a graduated cylinder. Run the system breifly and watch the graduated cylinders, you will see real quickly how each one is performing. Adjust as required and repeat until you are satisfied. Cheers Jim
