Lamborghini Marine Power

[MarcelloGandini]

The Lamborghini factory had never entered any kind of racing, the only Lamborghini's that ever showed up on the track were private entries, but when the Mimran's arrived, things changed.
Note that the late Ferruccio Lamborghini actually had two four-liters V-12's installed in his personal Riva Aquarama back in 1969, so Patrick Mimran decided to use an enlarged version of the V-12 for off-shore powerboat racing. At that time there were plans for a large-displacement engine ready, but Mimran decided to actually produce them, in 1984 the development of these engines began, end led to 8200cc and 9300cc engines.

However, these engines were too big and too heavy with their special fuel-injection systems and sophisticated mechanics to be fitted in a Countach or even in the big LM-machines.
Nevertheless, they were just right to be installed in the big off-shore powerboats. The 8-Liter engine, a 60-degree V-12 boasting 7973.89cc and a bore/stroke of 97.5x89 mm could produce 720 Bhp at 6000 rpm with its fuel injection system, but it weighed in at 360 Kg. However, these engines had a dry sump lubrication system and could rotate clockwise or counterclockwise, which made them perfect for powerboats and with their 360 Kg, they were still less heavy than the big piston diesels usually installed in this type of boats.

Aldo Cichero designed the 'Bull of the seas', the luxurious Lamborghini Quetzal 1 and the competition type Quetzal 2, both boats used a single-hull design consisting of a three-layer molding, a new composite material created by Cichero which used superimposed layers of PVC, Kevlar and carbon-fiber. The Quetzal 1 was very lavishly finished, with a lounge/bedroom, a kitchen, a bar, refrigerators, air conditioning, hi-fi, telephone, radio, television, etc. Naturally, the Quetzal 2 did not have any of these luxury items, but it did put out 1440 Bhp by using two 720 Bhp fuel injected V-12 engines.

Lamborghini engines became used for competition from 1985 on, mainly with the help of Daniele Audetto, Board Member of the International Powerboating Federation.
CUV singe-hulls powered by Lamborghini engines made their entry in the Italian and European competition, and even won the title thanks to the results of the Italian ace Renato Della Valle. In 1986 the same results were obtained, but 1987 became much harder, mainly because the Lamborghini powered single-hulls were not very competitive in calm, flat water, where catamarans are much better suited.

However, in 1987 the Sant'Agata engines did win the prestigious Viareggio-Bastia-Viareggio, mounted in the 'Sun International' of Stefano Casiraghi and the Cowes-Torquay-Cowes, in the 'Rocky' of J.P. Frutier.
That same year, the grueling New-Orleans-St. Louis, a 1034 mile race on the Mississippi River was won by a Wellcraft-Scarab powered by Lamborghini engines and piloted by none other than Don Johnson (famous from the television series Miami-Vice) in a world record of 19 hours 51 minutes.
Thanks to these results, a contract was signed with Mercruiser, who would buy 300 engines and distribute these in the United States. Two types where supplied by Sant'Agata, an 8.2-Liter version for racing and a 9.3-Liter for pleasure boating. The 8.2-Liter engine, type L 804 was used for the 1989 offshore competition.

Bunlarda lambo tekneleri.....motor güçleri mükemmel
offshore tekneleri,hatta boğaz da yapılan yarışlardada vardı victory isimli tekne lambo idi.bi kaç tane daha vardı lambo motorlu tekne...
bu arada 5. resimdeki motorda tubi yazıo çok ii yaw...

[BahaMax]

vay vay vayy alda arabaya tak cinsinden

Acaip makineler..
Herhalde dünyada en iyi maika üreten firma..

[blackjack]

Discoveryde izlemiştimde bu tekne yarışlarının ilk dönemlerinde adam 9-10L hacmindeki motorlardan 4 tanesini falan bağlamıştı tenkeye...Motorlardan oturucak yer kalmamıştı...Ama bunların bitanesinden az güç üretiyordur heralde 50 yıl önceki teknolojiyle

Muhteşem gerçekten...

feci aletler yaw
kaç sene once izmir korfezde izlemiştim bi yarışı, cidden zevk veriolar... içinde olmak nasıl bi histir, hep heveslenmişimdir zaten butur aletleri kullanmaya...

[MarcelloGandini]

en güçlülerinden biri 880hp...ve bir teknede 2 tane bu motordan oluo...1760 hp ....
ve bu deniz üzerinde çok büyük bi rakam...hafif bir deniz aracı için fazla deil astronomik bir rakam...hani normal yatlarda bile tek motorun 3 te 1 i kadar bi bölümü kullanılo...hakkaten muhteşem motorlar...

[blacksporting]

İçinde olmak isterdim

İçinde olmak isterdim

Bence hiç istemezsin...
Çok sert, darbeli ve sallantılılar..

[scorpio19]

baştan 3.resim aşmış...kullananlar çok şanslı
