Schimbare diferential Options

[alex230ro]

Cum multi dintre voi stiu deja acum cateva luni am achizitionat un autoblocant (LSD) de 4,10 tot de atunci stau si analizez care ar fii efectele acestuia asupra masinii.Iata ce rezultate am obtinut folosind un programel numit Car Test:
1.masina echipata cu diferentialul standard de 3,23 avem:
0-40 km-2,1 s 0-80km-5,9 s 0-100km-8,9 sec top speed 207,4 km 0-100m 6,9 s 0-400m 16,3s @140,3 km
0-1000 m 29,8s @174,6 km viteze maxime atinse in treptele de viteza:1-55km 2-97km 3-153km 4-216 km toate la 6000rpm
2.masina cu LSD 4,10 0-40km-1,7s 0-80km-6,1s 0-100km-8,5s top speed 207,1km 0-100m 6,7s 0-400m 16,1@138,9
0-1000m 29,5s @175,5 km viteze maxime atinse in treptele de viteza:1-44km 2-76km 3-120km 4-169km la fel la 6000 rpm.
Din ce vad montarea ar insemna un demaraj mai bun pana la 100 km si un sprint mai bun in aproape toate celelante ipostaze fata de masina de serie mai putin 0-80 km ,dar din ce vad viteza maxima atinsa in treptele 1-4 va scade dramatic.Am avea :pro 4,10 demaraj superior reprize mai rele avantaj LSD contra:consum marit comportament periculos pe carosabil ud sau acoperit de zapada si motorul va merge mai turat.Astept pareri legate de aceasta schimbare.

Intre timp am mai facut aseara niste simulari 5-100 km sau rolling start acceleration rezulatele sunt uluitoare:
1.diff standard avem
ROLLING START ACCELERATION RESULTS

Starting vehicle speed: 5 kmh
Starting engine speed: 540 rpm
Starting gear: 1st

Optimum Shift Points:
1st 6000 rpm @ 55 kmh
2nd 6000 rpm @ 97 kmh
3rd 6000 rpm @ 153 kmh
4th 6000 rpm @ 216 kmh

Time to Speed:
5- 40 kmh............ 3.5 sec.
5- 60 kmh............ 5.5 sec.
5- 80 kmh............ 7.3 sec.
5-100 kmh............ 10.3 sec.
5-120 kmh............ 13.6 sec.
5-140 kmh............ 17.6 sec.
5-160 kmh............ 24.5 sec.
5-180 kmh............ 34.3 sec.

Time to Distance:
0- 100 m............ 8.2 sec.
0- 400 m............ 17.6 sec.
@ 140.0 kmh
0-1000 m.(1 km)..... 31.1 sec.
@ 174.5 kmh

Top Speed............. 207.4 kmh
2. diff LSD 4,10 avem:
ROLLING START ACCELERATION RESULTS

Starting vehicle speed: 5 kmh
Starting engine speed: 690 rpm
Starting gear: 1st

Optimum Shift Points:
1st 6000 rpm @ 44 kmh
2nd 6000 rpm @ 76 kmh
3rd 6000 rpm @ 120 kmh
4th 6000 rpm @ 169 kmh

Time to Speed:
5- 40 kmh............ 1.8 sec.
5- 60 kmh............ 3.8 sec.
5- 80 kmh............ 6.2 sec.
5-100 kmh............ 8.6 sec.
5-120 kmh............ 11.5 sec.
5-140 kmh............ 16.4 sec.
5-160 kmh............ 21.9 sec.
5-180 kmh............ 32.1 sec.

Time to Distance:
0- 100 m............ 6.8 sec.
0- 400 m............ 16.1 sec.
@ 138.8 kmh
0-1000 m.(1 km)..... 29.6 sec.
@ 175.6 kmh

Top Speed............. 207.1 kmh
Se observa ca in acest caz diff 4,10 ofera un castig de minim 1 sec in aproape toate categoriile
