sexy head porting

[Patch]

Absolutely fascinating port work.

I have been staring at it in slow mo for a couple of days now, I thought I cough it up for you all to appreciate.

6 exhaust on one side 6 intake on the other, the weirdest 4 valve setup man can come up with.. The 3d model is the combustion chamber and runners.

I ended up doing some research on it and well its complicated?

And the runners are unequal in length... why design in what you need to compensate out?

 

Anyways what struck me most is the intake port machining impeccable. But if we imagine in cross section what we have is a velocity stack with the golf ball in reverse for static and mixing, amazing cnc machining. The ex ports are likely a 180 grit finish.

It would have been nice if they posted flow numbers before & after...

 

try it at 0.25 speed magnified to 150
