Are cineva documentatie cu privire la specificatiile axului cu came de JTDM 8V 120 cp? Va multumesc anticipat.

Informatia gresita a fost luata de aici"vnt turbo, injectors 119, stronger cr-pump, 4bar map sensor, rail sensor 1800, camshaft from stilo multijet, modified clutch & flywheel, big intercooler, custom built intake & pipes, multijet cam is higher lift." Extras dintr-o discutie cu Auto Evolution, echipa care are un punto de 220 cp, oamenii merg cu 1500 presiune rail. https://www.youtube.com/watch?v=cI6m2z8FX9g" onclick="window.open(this.href);return false;

Axa cu came este aceeasi si la JTD si la JTDM, indiferent ca e CF3 sau CF4, e posibil ca la cel de 80 cp cum e cazul acestor baieti sa fie CF2 si sa apara diferente, dar ma indoiesc. In concluzie axele sunt aceleasi si putem opta pentru C&B ca si upgrade.

La drept vorbind cred ca are instalat si W/M

Daca te uiti atent in film din cand in cand tipul apasa pe claxon, sunt curios ce are legat pe el:)

Daca e asa m-ar tenta si pe mine la urmatorul schimb de distributie un upgrade.

Sa vedem poate ne lamureste cineva mai documentat de pe aici

Oamenii au trecut de la 8v la 16v, respectiv de la 13.4 la 13.08 dar cu masina mult mai usoara fata de atunci cand era 8v. :)

Gata, datorita lui yan.ko de pe alfaowner: "Stock EUR3 8V JTD camshaft has following parameters
lift: 8.5mm both
inlet: opening 0° BTDC, closing 32° ABDC - duration 212°
exhaust: opening 40° BBDC, closing 2° BTDC - duration 218°

(btw, EUR2 has the same inlet timing, just exhaust timeframe is a bit postponed - opening 32°BBDC, closing 0°BTDC - duration 212°)


8V C&B MJTD.089.272S spec
lift: 8.9mm both
inlet: opening 28° BTDC, closing 64° ABDC - duration 272°
exhaust: opening 57° BBDC, closing 21° ATDC - duration 258°"

:D Pe cat de mari sunt diferentele tehnice dintre axul cu came C&B si cel stock, pe atat de mici sunt castigurile de putere. Din seria "pana nu probam nu vom sti", peste cateva luni vom achizitiona si un ax cu came C&B, dar inainte de asta trebuie W/M. Deocamdata avem injectoarele defecte. :cry: :(

Axul ar cam fi ultima strigare dupa ce ai epuizat toate celelalte modificari pe care le-ai putea face...
Sincer raportul intre costuri/castiguri este cel putin dezastros :)
Pe lângă ax care e undeva spre 500euro te mai costa un kit de distributie + manopera.

Ar fi interesant totusi de studiat ce alte axe se potrivesc la noi de pe alte motoare si care ar putea aduce beneficii

Faceti va rog un topic sa se inteleaga despre ce-i vorba, ca asa tot citesc si vad discutii despre axele cu came dar nu inteleg despre ce proiect e vorba sau ce se intampla.

Alex, are dreptate Andrei. Hai sa facem un topic! Eventual, rog un moderator sa mute topicul la tuning/upgrade si dace este cazul, sa schimbe titlul in ce considera de cuviinta, un titlu "edificator". Va multumesc.
