Teoreetiliselt peaks selle kindlasti toimima saama, tulebki lihtsalt kalibreerida, nagu mitme klapiga mootoreid ikka (paljud tsiklimootorid, näiteks). Mõistlik oleks igaks juhuks panna siis ilmselt ka topelt rõhu- või segunäidik?jeff01 kirjutas:Kas eraldi sisselase mis on väikese toruga rõhkude võrdsustamiseks ühendatud on halb mõte? st et parempoolne turbo puhub paremal asuvatele silinditele ja vasak vasakutele kuid väikese ja ilmselt mitte väga voolava toruga ühendaks kusagilt ära juhuks kui turbodel väkene õhkude vahe peaks tekkimaja turbosid juhiks ühest kohast võetud rõhuga...Selle reostamiseks oleks vaja siis küll 2 gaasiklappi ehitada ja kalibreerida kuid miskipärast see mind ei hirmuta :D
Lühemad runner'id on üldiselt vist paremad kõrgemate pöörete jaoks, pikemad madalamate jaoks. Pakun, et madalatel pööretel pöördemoment kannatab.jeff01 kirjutas:mis juhtub kui segusiibri ja klappide vahel on liiga vähe mahtu
Mina olen teinud 1mm raadiusega ja on väga hea saanud. Turbokal võiks igaks petteks olla ka 1,5mm raadius.jeff01 kirjutas: Kas ja kui suure raadiuse peale peaksin lihvima põlemiskambri randid (Kaaned on tutikad ja randid üsna teravad, kardan hõõgsüüdet)
