I know this thread is dated, but I just wanted to clear up a few things.
Interesting info.
What is the significance of the "Ignition Break Points" table?
The breakpoints were used for Engine Analyzer Pro to mimic the ignition at WOT. More of a personal reference for me (or anyone using EAPro) than anything.
They look like they are only for full load mate; not really of any great significance.
for everyone else's FYI, ignore the flow rates 0.5" and over, 99% of those cams don't exceed 0.45" of lift. personally, I would not recommend running a cam that results in 0.5" or more lift with standard rocker arms / lifters; simple fact is that the wear between the cam lobe and the rocker wiper pad will increase due to the high spring open pressures at those lifts.
large lift cams like that really need roller type rockers to reduce cam lobe wear.
I'm not sure why you would ignore the flow rates above 0.5". The stock 240sx cam (0.409 lift) has a total valve lift (cam lift * rocker ratio = total valve lift) of 0.581".
0.409 * 1.422:1 = 0.581 Total valve lift.
As far as wear and roller rockers go, I'd be all for a pair of those. In the mean time tho, I'll stick to my tried and true Mobil 1 15w-50.
