I see some people have shown some interest although no one has replied. I also posted this over on Speed Talk.
This is what Mike Jones / Jones Cam Designs had to say.
Quote:
Looking at cam acceleration is meaningless, without knowing the rocker ratio. A cam designed for a 1.5 rocker, can get away with a higher cam acceleration, than a cam designed for a 1.7 rocker. It's valve acceleration he should be looking at.
as for max cam acceleration, I looked at one of my most aggressive Pro-Stock profiles(277@.050", .538" Lobe Lift).
On that profile, max accel is .000439
Our winningest Dirt Latemodel Intake profile had a max accel of .000486
The cam that powers the worlds fasted LT1-Gen5, has a max accel of .000405
On our Buick V6 Indy cam that set the record in 1992, accel was .000312
Here's some other people's cams I have checked
AMG: .001060
Brayton: .000417
Bullet: .000381
Comp: .000423
Comp: .000352
Comp: .000356
Musi: .000440
Musi: .000413
Murcury Marine: .000519
Schrick: .000522
These are all Cam accel, and don't tell you anything, without the rocker ratios
The 2 highest(AMG and Schrick) are both overhead bucket follower type cams, so they have no rocker ratio to multiply by. Their cam acceleration is their valve acceleration.
