Perfect intake centerline

Wedgy Perfect intake centerline
Hi together,

how can I calculate the perfect ICL for my engine?

Best regards - Martin



Remember that the intake valve closing point will change the dynamic compression of the engine.
A engine cannot make any compression until the intake valve closes shut.

This is what your adjusting when installing your cam.
The intake valve closing point.

The perfect ICL is choosing a cam that shuts the intake valve at the right time to give you the cylinder pressure you would like and also the rpm band you would want to see your engine operate at most efficiently.

This is why most small performance cams have a faster closing intake valve.
A faster closing intake valve helps a lower compression engine make more power due to trapping more air at a lower rpm.

A higher rpm engine will close the intake valve at a latter time and can get away with this because the engine is used at a higher rpm.
The cylinders are being filled more efficiently due to the rpm.

This is a complicated subject and it can go on and on and on..................

PS
I understand the basics of camshaft blueprinting but this is where my knowledge ends on the subject.

Every engine needs a cam but what cam will it be?????
This could be the biggest bench racing subject ever.

GOOD LUCK.:salute:
