Kukho iindidi ezimbini ezahlukeneyo zeenjini ze-V8 ngokuxhomekeke kwi-crankshaft.

Inqwelomoya ethe nkqo sisakhiwo esiqhelekileyo seV8 kwiimoto zendlela zaseMelika. I-engile phakathi kwecrank nganye kwiqela (iqela le-4) kunye neyokuqala yi-90 °, ngoko ke sisakhiwo esithe nkqo xa sijongwa ukusuka kwelinye icala le-crankshaft. Lo mgangatho othe nkqo unokufikelela kwibhalansi elungileyo, kodwa ufuna ubunzima obunzima bentsimbi. Ngenxa ye-inertia enkulu ejikelezayo, i-injini ye-V8 enesi sakhiwo sithe nkqo inesantya esisezantsi, kwaye ayinakukhawulezisa okanye yehle ngokukhawuleza xa ithelekiswa nezinye iintlobo zeenjini. Ukulandelelana komlilo we-injini ye-V8 kunye nesi sakhiwo ukusuka ekuqaleni ukuya ekupheleni, efuna ukuyilwa kwenkqubo yokukhupha eyongezelelweyo ukudibanisa imibhobho yokukhupha kuzo zombini iziphelo. Le nkqubo yokukhuphela intsonkothileyo kwaye iphantse yanzima ngoku iye yaba yintloko enkulu kubayili beemoto zomdyarho ezihlala umntu omnye.

I-Plane ithetha ukuba i-crank yi-180°. Ibhalansi yabo ayifezekanga kangako, ngaphandle kokuba i-balance shaft isetyenzisiwe, i-vibration inkulu kakhulu. Ngenxa yokuba akukho mfuneko ye-iron counterweight, i-crankshaft inobunzima obuphantsi kunye ne-inertia ephantsi, kwaye ingaba nesantya esiphezulu kunye nokukhawuleza. Esi sakhiwo sixhaphake kakhulu kwi-1.5-litre yomdyarho yala maxesha iCoventry Climax. Le njini iye yavela kwinqwelomoya ethe nkqo ukuya kwisakhiwo esisicaba. Izithuthi ezinesakhiwo se-V8 ziyi-Ferrari (i-injini ye-Dino), i-Lotus (i-injini ye-Esprit V8), kunye ne-TVR (i-Speed ​​Eight injini). Esi sakhiwo sixhaphake kakhulu kwiinjini zomdyarho, kwaye esaziwayo yiCosworth DFV. Uyilo lwesakhiwo esithe nkqo sinzima. Ngesi sizathu, uninzi lweenjini zokuqala ze-V8, kubandakanya iDe Dion-Bouton, iPeerless kunye neCadillac, zenzelwe ngesakhiwo esicaba. Ngo-1915, ingcamango yoyilo oluthe nkqo yavela kwinkomfa yobunjineli beemoto zaseMelika, kodwa kwathatha iminyaka eyi-8 ukuba nendibano.
