Cel mai preformant motor diesel ???

[avolocaru]

Salut
Ma rog... cel mai performant dati si voi o parere. As fi interesat de un v8 cu 2...2,5 L capacitate cilindrica.

V8 de 2-2.5 L , gasesti eventual pe motociclete,ca si capacitate.Insa diesel....
Eventual V6 de 2.5L
V 8 este un motor specific american,care se "jucau" in genere cu capacitati de la 5.o L in sus.

Ma rog atunci sa zicem ca ca poate sa fi si de 3-4 L important e sa fie in 8 cilindri (avand in vedere ca si consumul de carburabt e o problema, am sa vad la un moment dat poate fac un compromis la 6 cilindri).
Pentru inceput ma uit la performante, adika vreau ceva puternic si un cuplu cat mai mare, apoi o sa mai vad cum sta treaba si d.p.d.v. al gabaritului.
Cel de la Alfa-Romeo in 6 cil e interesant. Mai astept si alte pareri.
Merci tuturor

Parerea mea este ca 2000cmc (T)diesel nu vei gasi nici V6,d-apai v8. Cel mai mic V6 diesel de care am io cunostintza este cel de la VAG, 2500cmc.
....DAR...am o intrebare...: Intrebi ca fapt divers,pentru cultura generala sau ai intentia de a achizitiona asa ceva? ca in cel de-al doilea caz, mult mai avantajos ar fi sa-l iei cu tot cu....ambalajul.Iar cele doua exemple date de turbojack, sunt impresionante ca si performantze,numai ca nu prea le-am vazut implementate in ceva...poate la jaguar sa fie unul din ele,dar nu-s sigur.
Io am mers cu doua "petroliere" V8 : Lancruiser si S-classe. Pe ceva mai "parcabil"(la dimensiuni ma ref., nu la manevrabilitate) nu am avut ocazia de a gusta cuplul de V8 diesel.

Ajunge la 200 cp, ca si cel de 2 l de la BMW preparat de Alpina, insa e interesant (poate pentru ca ar fi singurul diesel performant pe o masina frumoasa). Motorul de 3 l, 6 cilindri in linie de la BMW ramane taticul lor. Urmat de 3l CDI de la AMG!

[200SX]

3.5 biturbo de la bmw cred ca e un motor destul de tare diesel

[einstein1984]

Are doar 3l. Denumirea il face sa se deosebeasca de cel cu 1 turbina.

Salut!
In primul rand nu intreb doar ca sa ma aflu in treaba. Visez la o masina de teren... sa zicem... BETON. Pentru inceput ma intereseaza un motor diesel performant. Nu sunt foarte priceput la motoare dar am inclinatii tehnice suficient cat sa ma apuc "tuning" (asta e alta problema).
Prin urmare, daca ar fi sa va construiti o masina de teren accidentat, ce motor credeti ca ar fi cel mai potrivit?

[avolocaru]

Revin!
Eu chiar am intentii serioase, dar trebuie sa ma intelegeti ca inainte sa arunc cu banii trebuie sa ma interesez foarte clar, pentru ca nu-mi permit sa mai fac o incercare. Dupa ce ma voi hotara asupra a 1-2 motoare, ma intereseaza un diferential pentru spate (am inteles ca sunt unele blocabile pe roata fara aderenta), apoi asupra suspensiilor, etc.
In rest... le potrivesc eu, ce naiba sunt doar niste bucati de "fier" se taie se sudeaza... trebuie sa iasa ceva.

Aha! deci asta era ideea.
In cea mai mare masura depinde de citi bani dispui pt. acesta investitie.degeaba iti dau date de Hummer la care doar motorul e 15 k $ daca ai bani doar de un ford in V 6.
Iar ceea ce vrei tu este ceva mai mult decit de a taia si suda niste "fiare".
deci cit vrei sa investesti in afacerera asta?Pt. ca de la bani pleaca totul .
