Dominik Posted February 2, 2014 Share Posted February 2, 2014 Kolko velke ventile ti imas nutra? bravo fire, konacno dobro pitanje, mozda od tebe i bude nesto ..... 2 Josip 38mm ti je sigurno dosta i s dobrom efikasnoscu ..... jer citav proracun strujanja je stvarno kompleksan i onda se dogadjaju stvari da se krivo zakljucuje ... za sve je rezultat neznanja ..... tebi je s tlakom,brzinom strujanja i rezonancijom cilj ugurati sto vise zraka kad se ventili zatvore pa je bitna cijela ploha punjenja ne pojedine tocke, a ona je drasticno veca na ITB-ima nego 1 zaklopkom, jel je to fizikalno matematicki lako dokazivo, i puno se lakse kontrolira ....

JosipZG Posted February 2, 2014 Author Share Posted February 2, 2014 (edited) 2 fire Ok U planu mi je kroz neko vrijeme nabavit jos jednu glavu, napravit portanje i stavit vece venile (od c2 vts) tako da je onda u svakom slucaju bolje stavit ove od 40mm Dominik po tebi ipak bolje 38?

Dominik Posted February 2, 2014 Share Posted February 2, 2014 pa za tu snagu koju hoces da a za maximum sta se da izvuci bi morao ipak znati svu geometriju motora i sve u software ubaciti i to posteno izracunati ... Link to comment Share on other sites More sharing options...
ZOD Posted February 2, 2014 Share Posted February 2, 2014 (edited) Kad če ti netko radit taj usis za itb, pobrini se da taj netko zna di trebaju ić itb-i Dominik ma kakav softver?

Hic Posted February 2, 2014 Share Posted February 2, 2014 Po mogucnosti napravis dvokomornu, pa smanjis "pumping loses", sve ima svoje, pa i na ITB-ima Link to comment Share on other sites More sharing options...

Po mogucnosti napravis dvokomornu, pa smanjis "pumping loses", sve ima svoje, pa i na ITB-ima Kak to izgleda?

ZOD Posted February 2, 2014 Share Posted February 2, 2014 Dvokomorna na ITB za atmosferca? Nestavlja se. Samo neka napravi airbox većeg volumena sa adekvatnim dovodom zraka. Josipe da na to sam mislio Link to comment Share on other sites More sharing options...
Enkei Posted February 2, 2014 Share Posted February 2, 2014 Samo da pitam nešto kada se već načela tema... Koliko je pametno slagati sustav gdje se zrak vuče iz motornog prostora? Link to comment Share on other sites More sharing options...

JosipZG Posted February 3, 2014 Author Share Posted February 3, 2014 Josipe da na to sam mislio mislio sam ih postaviti što bliže(sama klapna bi bila na nekih 13-14cm od ventila) a onda sa trubicama podesiti duljinu kanala. "izračunao" sam da bi ukupno trebalo biti nekih 30cm od ventila do kraja Link to comment Share on other sites More sharing options...
jura93 Posted February 3, 2014 Share Posted February 3, 2014 Za visoke okretaje veca udaljenost. 13 - 14 cm od ventila je premalo. Link to comment Share on other sites More sharing options...
JosipZG Posted February 3, 2014 Author Share Posted February 3, 2014 krivo sam napisao, 13-14 bi bilo od klapne do kraja trubice a od ventila do klapne 16-17. Link to comment Share on other sites More sharing options...
