Thank you sir for sharin this info. Simply the best way to explain cam timing I have seen! I will do also the writing right to left 😉 Thanks and all the best, Juhana
#1 intake valve closing - determined by the details of the operating intake system-largely determines torque peak and peak tq rpm #2 exhaust valve opening- determined by the details of the operating exhaust system. #3 overlap - determined by both the intake and exhaust systems. Dyno testing followed by track testing is the only way to really determine these events. All the systems must be coordinated to work the way you need it to work.
Nah, you are talking about "advertised duration" marketing dishonesty. I am speaking of actual lobe / valve events verified with a degree wheel and dial indicator.@@baby-sharkgto4902

👍👍💯
Overlap is expressed in seat to seat not @.050
MAN THANKS FOR ANOTHER GREAT VIDEO

This is an old video but I like it. How do you decide, based on cubic inch, compression and rpm range, what the events should be?
Does LSA depend on the valve to piston bore ?
What are the event percentages? What do they represent and how are they derived?
They represent what he feels is the relative importance of those events in the total output of the engine.
How do you determine you're opening and closing valve events to begin with?
#1 intake valve closing - determined by the details of the operating intake system-largely determines torque peak and peak tq rpm
#2 exhaust valve opening- determined by the details of the operating exhaust system.
#3 overlap - determined by both the intake and exhaust systems.
Dyno testing followed by track testing is the only way to really determine these events. All the systems must be coordinated to work the way you need it to work.
What is the reason for using @.050" events instead of seat events? Thanks
To have an accurate standard and to eliminate “fudging” aka fakery

Lol....just pickem out. Who cares about your silly seperations.
