Re: R/S ratio
TDC dwell = BDC dwell

Re: R/S ratio
stroke only decreases the time a piston will spend its time in x amount of length of cyl walls.

Re: R/S ratio
it's the same to tune cams in both case?

Post some.

Re: R/S ratio
One word for those that honestly want to know, but don't have all the cards: trigonometry.
Here, a second: triangles. A third and fourth: common sense. |
Re: R/S ratio
parroted? o rly? I'm sure I read that on D-series.org, but I'm probably wrong. And seeing as the amount of dwell being different between BDC and TDC, this is physically impossible for the engine, seeing as it would neccisitate a variable stroke crankshaft or con-rod. Jah?

Re: R/S ratio
The difference between you and me is that sometimes I can remember everything I ever read, and everything I ever said, and I know where it's at so it takes me a minute fifteen to find it with HMT search engine broken. :P
