I did not grind the stem as it is highly stressed. I don't feel the back of the valve will have any stress riser issues but it is a good point.

I would love to see a back to back dyno test. Depending on the carb or injectors ability to atomize the fuel it might help. I always try to test as much as I can, because theories are great, but proven facts trump theory all day long.

Too bad my current life situation does not allow me the time to test the idea.

1008171849a_HDR-1_2.jpgForgive me for posting this in more than one thread but I want DV to see this before I send out his next shipment. After seeing cnc work on the back of a valve I wondered what could be done by hand. I grabbed a used up 1.94" Chevy valve and did a bit of burr work on it. Interested in opinions on this. Thanks, Charlie

I think my feelings are hurt!

Umm, no they aren't.

Still waiting for pics of your work Warp. There must be something that isn't top secret you can share. Thanks, Charlie

You would figure my fuse would grow with old age. Not so much.

Just the opposite for me... my tolerance for unnecessary b.s. is far lower these days. #-o

Looking with great interest at the info and pics posted here with the almost 'as cast'-finishes and I'm wondering how this all relates to the ripples visible on sea floors or desert sand dunes and such.
Isn't nature already providing a good (the best?) example of how a finish should look like to promote flow?

Thinking a step further, could an exhaust tube/system machined internally with these kind of wave-textures provide any gains?

Nature has found the best design for many problems. If you think flow look at bird feathers or fish scales. We can learn plenty.
