Countach Downdraft 1985 to 1988.5

I find it somewhat ironic that Lamborghini homologated the DD, and yet Porsches 959 so often espoused as a Group B car was in fact never homologated by Porsche.

Interestingly the Countach is one of 11 cars homologated after the main Group B ban, a list that includes several versions of 964 shape 911, Jaguar XJS and even the mighty F40 LM.
Most of the 11 were later shifted into the relevant FIA GT categories, do we know if the DD was too ?

 

you have mail

 

basically this is afaik a DD car converted to Individual Throttle Bodies.
ITB's are great - the idea is that they have the benefits of a carb style airflow (ie no bottlenecks) but with the carefully metered fuel of an injection system.

they also due to the design and airflow give a very very similar noise to a multi carb setup unlike the more muted noise normal fuel injection tends to give.

modern aftermarket ITB systems can be superb.
the ecu's are hugely powerful and utilise proper 3D maps
gains of well over 10% on otherwise standard engines are the norm

the key is good mapping.

I would not be surprised to see this QV ITB make close to 500bhp without much more done except finding the right person to map it

most RR's will give you 2 sets of figures.
at the wheels - which is an accurate reading, though can be upset by tyre pressures etc
and
at the flywheel - which uses coastdown to "best guess", and is wildly innacurate.

if you want to be more general then the industry accepted rule of thumb figure on a rwd is circa 17% transmission loss - assuming good condition etc.
so basically if you take your "at the wheels" figure as roughly 83% of the flywheel figure you will likely be in the right ballpark.

those figures in the picture btw will likely be "flywheel" ones attained by coastdown.

so anyways this means an average 455bhp DD should be 378bhp at the wheels assuming its healthy (and that they truly had 455bhp - which i do believe)

 

It is possible, my friend who studied in Switzerland back in the time has owned 4 Countach's from 85-89 whom he daily drove to University.

He is from KSA and last car he owned was a Black LP500QV with white interior.

 

Oh my gosh...that is an amazing get together. I wonder how many actually reside in Japan?

 

I dis-agree with you..multiple places state the rating I have stated. They are (all Countachs) great cars. However we cant go around saying so and so and so and so "Told me...".

I would never advertise a car for sale based on those loose hand me down words...you would have a CPA LAWSUIT on you so fast your head would spin.

You have to use the documented findings by many many outlets and publications. If not, you need to have documentation of your claims with your OWN DYNO testing, at least two separate ones on different machines and condition's of temperature. This would work to a specific car.

While I have no second thoughts that there are engines that can and do reach what was told to you by an ex factory worker. This information is not and has not been considered correct for ALL DD cars. If it were it would have been published by the factory to the betterment of the Brand. We must be safe and correct to go with the published HP ratings, not the "he said she said"... pass me down numbers.

This kind of "Legend speaking" does NO brand any good. Lets stick to the documentation of the multiple test cars...and if you have a DYNO for a specific car..GREAT post it in regards to that SPECIFIC car, not the whole lot of them.

This is IMO. I of course would never provide "un-documented" claims to a vehicle that are not in writing and substantiated. It is just not good for the buyer or the Brand IMO.


Lamborghini Countach LP 5000 QV 455 hp - Specs & Performance

 

Bloody hell!!!!

 

We recently hosted the first ever "Collectors Weekend" at the famous Bal Harbour Shops in Miami. Some of the greatest watch and car collectors brought out their "Sunday's Best," for display including Jim Glickenhaus. Glickenhaus journeyed South to show both Ferrari P4/5 by Pininfarina and SCG 003!

Besides P4/5 and SCG 003... our Countach Downdraft got the most incredible attention amongst an original Daytona Spider, Pagani Huarya, LaFerrari, 918 Spyder and much more!!

And yes, thats rocker Tommy Lee admiring the icon!

As I stated, this is IMO. I see however you take it as a personnel attack, which you should not..once your car is complete I am sure, as well as hope, you post the results of its 2 tested dynos results.. I hope it gets 500HP that would be great. As I said, I am sure there are many that can and do make more then the Public Posted HP for records..

My DD?? I have no idea its HP, as I just enjoy driving it as I do all my cars..BUT when and if I sell it..I surely WILL not advertise a HP that is not documented...

so when you get yours documented, if thats what you want to do, post it for us all. I wish you all the 470 HP well wishes in the world..
