Can't wait for flow #'s

:whs:

I will take one flow numbers order please.

That looks great! I am curious to find out which part of the exhaust side was the most restrictive the big hole or the valves.

That's signature material right there!

Any updates?

so we finally have some updates!!!!

we got @fifthofbourbon 's head finished up with the +1 valves and we have some great results!!! The redline on the graph below represents the max lift of the stock exhaust cam so show you where you wont benefit any further without more lift. Now this is just the exhaust side but we will have intake side results very shortly.

So about 50 cfm? Very nice

I think saying "over a 50% increase" paints a better picture

Thats not really over, its pretty much 50% at max lift. Now we just need some cams to take advantage of the flow

Maybe i really am THAT far out of the know-how... but what does the exactly translate to, outside of just CFM being increased by 50%?

Assuming you know of the effects of the CFM being increased, they've reached the limit that the exhaust ports can flow with the lift provided by the stock cam. The cam lobes actuate the valve, the amount that the valve opens from this is called lift. They have reached the limit on how much air can be pushed around the valve with that amount of lift. To get more flow you would have to swap in a cam that will open the valve more(more lift) to allow more airflow.

Edit-CFM being increased means the cylinder head has greater airflow. More airflow + more fuel = more power

Ugh, I really don't want to pull my turbo off again to do this

Yes you do... I do too.

How could you not?!?

Having cams with a larger lift would basically move that vertical red line to the right allowing you to increase the overall "area under the curve"

Porting Pictures you Posted

SP63:

Are those pictures you posted of the "Porting" - MILD or AGRESSIVE?

Daaaammmm

Any updates on flow numbers?
