Topic for pro's only so I hear.
Playing with an engine dyno sim.
Assuming stock 3.8 rotating, using abbott racing heads stock and stage three flow numbers and an M90 as the power adder
Things I've observed:
It seems lift doesnt matter much as long as you have enough to reach the max flow of your heads.
500 thou or slightly over is all you seem to need for optimum power up to 6000 rpm.
duration is good up until around 220, then gains quickly turn into losses down low.
Ramp rate has a huge affect on power. Higher the ramp rate, the more power overall the motor would apparently produce.
Overlap, seems to be bad. 0 overlap results in best power. LSA 111.
ess overlap, say -15 you see a loss in the top end, yet no gains down low.
LSA of 114.3 or so.
10* of overlap sacrifices power under 3000 for power from 6000-7000. LSA of 108.5
Next week, I attempt to find out why this is, or how I've made mistakes here.
