it's the stock chamber, de-shrouded. And what looks like a monster valve, the seat on the intake comes out to the deck if I am seeing that right! They make cutters to do the de-shrouding, or it might be apart of their valve job cutter. We have one that does the same with a oversize valve. We just don't leave it that way, as there are alot of sharp edges left..kind of like this picture..every edge seen is sharp.

 

Don't think that a finished CC. My head and Ted's are both from Headway and niether looked like that. I'll find some pics...

 

What was the CNC head that Dyno Flash Al put on his car and it actually lost power??

 

Thanks Walker that would be great...Jim

 

Is there anything you can do when working the CC that could affect spark and how well it works?

I'm not actually referring to your heads but its just a general CC related questions.

Thanks.

 

headway if i remember correctly....

EDIT..heres the link https://www.evolutionm.net/forums/ev...-hta88-11.html

 

I thought it was but wasn't 100% sure.

 

Very nice. I do minor port and polish on heads and never touched the bowls because I didn't want to chance hitting the guides.

That pic of Headway's head seems unfinished. The bowl is not even smoothed out.

 

If the turbo is already wound out and a high PR situation exists on the exhaust side, a ported head cannot net you any more power. In fact, it could hurt you (as Al discovered).


It's definitely unfinished.

 

i thought it was a cosworth head.

 

There is a video of it online maybe on his youtube vids. It was a headway head. And most people that go to the extent of getting head work done are going to be running turbos to there max and pushing limits etc. IMO if a head is done right you will gain power, not ever lose it.... I know im pushing my 850R decently at 40-41psi and i seen gains from the work i had Head Games perform on my head.

 

agreed...we have never lost power from a head..it would make the power at a lower boost level if we are at the breaking point of where the turbo makes power at. If you lose power, you have other issues going on there.

 

If the turbo compressor is at its limit, a ported head isn't going to magically suck more air out of it - simple physics.

If the turbine side is in a high PR situation, a ported head isn't going to magically push more air through it - simple physics. Anything that facilitates reversion in such instances (e.g. big head, big cams, etc,.) can decrease power. This is basic FI knowledge.

Anyway, this isn't a discussion about Headway, their CNC work, or their track record in competitive racing. It's about Headgames' CC procedure. Carry on...

 

don't know why I didn't see this....but you must be talking about a certain head on our flow bench that we very easily made a little wicked with some HeadGames magic...








It is coming soon

 

Headgames can you answer my question above? Post #20.
