Has no one else noticed the remarks between those 2? The constant undermining and one up man-ship has obviously taken it's toll on Peter's patience.
I also hope Peter can overlook the , cough, "attempt" of humor.

You are not welcome here any more. Take your 280C barge & go away.
I long suspected there was something wrong with our education system.
THAT is no way to speak to an ex-Gibson Racing Team engine builder - no matter what you 'think' you know...

I hope I/we havent lost Peter's knowledge, expertise and friendship. He's such a generous person with his time and is a true master craftsman, the Michaelangelo of cylinder heads thats for sure!

"restrictor..........needed to slow the water down to make the temp more stable"
Increase the pressure of the water around the head galleries is why a restrictor is used, nothing to do with the speed of the coolant.
Think about it for a second or two. Water boils at @87 degrees in the alpine regions for example....it's to do with the ambient atmospheric pressure. How do we increase the boiling point? Put a restrictor in the cooling system and the pressure of the coolant will increase. Now we can boil it at @120 degrees.
High school science stuff.
By the way Oz, the pressure in the whole cooling system, not just the head, is increased as the restrictor SLOWS DOWN the water flow. The pump is attempting to pump the same volume of water through the system, but it is SLOWED DOWN at the restrictor and results in the increase in pressure.
Now I could have typed this the first time I read your post, but I didn't as see the value in blatantly pointing out your error. I didn't see the value in hurting your feelings or embarrassing you. Obviously now I do.
Don't know what high school you went to or to what level you went, but I suspect that you should have paid a little more attention in physics class.
As a side it doesn't matter if you can spell well, when you have nothing worthwhile (or accurate) to say!
And yes technically it doesn't increase the pressure in the 'whole system', but rather the part between the low pressure side of the water pump and restrictor. I know that most would let that little exaggeration slip through to the keeper, but just in case you feel like taking on a battle of wits well outside your weight division!

For the most part I'm sure both parties have something valuable to contribute otherwise they wouldn't comment and in this case different opinions. Sure somebody 'may' or 'could' be wrong, but you also have to remember that offline many of you guys have close relationships, so when someone outside of that immediate social circle comes in I respect that many of you will jump to defend each other.
Also members should show mutual respect for each other, even though at times I know this can be difficult to do and you may want to really prove someone is wrong. Comments on forums can sometimes be hard to properly interpret due to the restriction in the medium's tone, I'm sure we all know this. Just look at the fighting over YouTube.
It may seem obvious and perhaps optimistic on my behalf, but perhaps we should take this incident as water under the bridge and move on?

That's not water under the bridge, it's Gareth's coolant.
