Countach QV FI Thread

Also the fit and finish on the factory euro bumper was horrific,we spendt a lot of time perfecting it, wich will make it a good candidate for reproduction,

 

Here is one cleaned up, but painted black. Image Unavailable, Please Login

 

Not really,this car got hick mick efi,blue hoses and ,as you said, black paint, not a good example,

Cool concept however I agree with ellagirl that it isn't a good example. EFI requires fab of the plenum; looks even more messy to my eye. Also the black....to each their own.

IMO the mechanical distributors look good once everything else is removed. Reminds me of a 935.

I like how you turned the air/innlet box 90degree, not a big fan of the orange hose/duct , my personal only, your engine bay looks great, lots of volume,in these manifolds, and agree on the 935 comparo, or pretty much everything from Porsche mid 70 s and on

 

I think the example I posted was done 15 or so years ago, but I would agree on the black paint. The effort Lamborghini put into the fuel injected version had more to do than just the US market. Just as a comparison this is a Diablo engine. Image Unavailable, Please Login

 

Image Unavailable, Please Login Like most have suggested, the biggest weight hog in the engine compartment, is that air pump and all the associated vacuum valves, etc...

One other item of interest, are the 2 brain boxes behind the right hand boot panel. Those things only control 1 thing on the fuel injection system. The “frequency valves”. Basically, the O2 sensors in the exhaust send their signals to those boxes to in turn send a signal to the frequency valves to add a more fuel to the mixture. If you remove the cats from the car and no longer use the O2 sensors, there is no need for those boxes.

Here is a blurb from Jason’s blog talking about it.

Exactly. Looking at the two together it's clear that Lamborghini used the research collected from the QV.

John, not sure if you saw this or not. I posted it awhile ago in the other Countach thread. Really shows the weight savings of the Quicksilver vs. OEM Ansa Box unit. Went from 72lbs down to 34lbs.

 

Is the system on the right the stock original unit,off your FI? Just curious, my cars original muffler system looks entierly different,beeing 2 smaller mufflers after the cat box, poss ,they used up the inventory before changing,my car is Oct 87,

Nils,

No, the previous owner removed the USA system (with the cat mufflers) and installed that ANSA unit which was on the euro models.

Thanks , do you also have the dd headers?,and are you running without the 2 Bosch computer units? This is very useful info,i would love to remove all garb.thanks

Nils,

I unfortunately still have the horrid USA headers. I really should have replaced them when I had the engine out of the car, but sadly I didn’t. Oh well, next time....

I have left everything in place on my car just to preserve originality. However, the O2 sensors are disconnected at the brain box under the RH vent cover. Here is a current photo of my engine bay. Note, original owner also painted the intake manifolds gray.

Image Unavailable, Please Login People often wonder what the USA headers look like..... this image that Chad posted on his website answers that question! I would never have guessed that they looked like this. I always assumed they were individual pipes just wrapped in a heat resistant aluminum.
