This thread is about the guy's video about DV system mainly about what he shows as proof.
I'm not saying DV overall concept is wrong (haven't seen anyone prove it right either) I've over and over said I generally like it but take it with a grain of salt. What I've argued is the evidence so far don't match his claims of optimal, 40-50 lbs-ft gains over conventional 110-112 lsa cams being closer to the 1% of builders that make 1.40 lbs-ft per cid etc.. No one has shown any evidence to those far as I know and if there is glad to see it.
The evidence I've seen so far basically shows every degree tighter you go you gain a bit of mid range torque, I'm sure there's a point it will stop for each engine but it probably tighter than most of us wants to go. This is basically common knowledge, this proves DV formula how?
