Har grubla litt over div program......interessa etter å vite meir inngåendes om luftstrømninger og andre ting som kan virke som bagateller,men som kan ha stor innvirkning på en motor,fikk meg til å bestemme meg.
Bestilte derfor dette pc-programmet,som har fått mye god omtale.
Ser ut til,og har hørt,at dette er ganske så alt-omfattende og langt bedre enn bl.a Desktop Dyno serien.
Her kan en som sagt programmere og endre på det meste,og få et teoretisk forklart utfall av desse endringene uten å måtte prøve alle mulige varianter i praksis.
En kan t.o.m eksperimentere med ulike plenum,turboer(A/R,trim osv) og berekne baktrykk og innsugs temp,trykk og intercoolerens effektivitet og nødvendig størrelse osv(ulik de billigere programmene)... Tids- og pengebesparende!
