It's obviously a little more involved than I thought, but in terms of combustion chamber size, they can be easily compared.
Along those lines, they could be compared with a comp gauge on a given engine, just as my stock head and billet head can be compared. 115psi vs 142psi
My questions have only been for the benefit of others, as a comparison between mine, (RSE billet) and the new one. Mine suits me, as I said. My only drama, as you remember was stud length, hence that question.
Does it need quite as much fin area? Mine is pretty meaty and runs at a pretty good temp. I'm thinking overhead clearance issues with some frames.
Tony doesn't give a psi figure, quite rightly it seems, but he does give a CR figure of 16:1.
I've never delved deeply into this stuff in the past, beyond shaving about 0.040" off a few heads when I was younger, with no idea of any figures when I was done.
I learn more every day here.
And potential customers know a lot more about the impending head.
I was a bit blunt earlier and owe a bit of an apology. Maybe even a whole one.
Wouldn't be the first time and probably won't be the last.
