... got me to do some Googling.



Discuss.

 

The exact same reason golf ***** have dimples. They need to be hexagonal!

 

are these intake and exhaust or just one or the other from what you have seen?

 

Interesting...




Where's the redheads?

 

 

In real world, I wonder if the dimples just end up trapping carbon and getting crusty?

 

I first pondered the idea of having dimpled ports when I was in highschool, I never thought of doing it to the valves.
I was thinking strictly from a flow standpoint, but Id imagine dimpling the valves ma have some other implications

 

+1
First thought I had when I saw them too.

 

probably, curious about possible gains though, can't imagine it would be much

 

if there isn't developed, laminar flow at the back of the valve, they'd do nothing.

if flow is interrupted by, say, a shaft and forced around a corner, it's probably no longer laminar at the boundary layer.

 

better fuel economy according to mythbusters....

 

on the outside of a car....?

 

I refuse to debate the topic until more red head evidence is introduced.

 

 

Redhead?

 

I dated a girl with a red head.. No hair, just a red head. Burnt up in a trailer fire.

 

no.

yes.

 

If regular valves carbon up, let's give it something better to grip onto.

And Y8s is an acoustical engineer, so I agree with him about the laminar flow.
