Pin heigth isn't extreme at all though as I run a very decent thick crown. Because turbo :lol:
And stroke is very mild as well: just 74mm, only 3mm over 'stock' :wink:
How do the cylinders fit into your Riechert style cooling?

Enjoy the build! :D

Like to know this too. I see a lot of use of them, but never see the trimming of shroud or cilinders
and how they fit.

Walter, those heads oelala… nice...

I really don't understand the concern: the fins on these heads are still VERY small. It looks like a decent amount, but imo they not that much fin surface in total. Less then stock anyways.
So, fitment will never be a problem imho. I would wish there was a problem :lol:

Heads are indeed totally awesome, but thats where the power lies as we all know :wink:
This was the effected cylinder, now all repaired:

Ok, I belief you on cilinder tins then.
Twinspark, peanutshape… damn nice… i think i have to start saving…

If you ever want a used set of Deutz 100mm cilinders let me know… I have several sets..

Noooo, Be is very toxic. You read too much ;-)
Its sort of a manganese bronze, also yellow-ish

8) yeah we have it in some components at work and the warnings are pretty serious.... i think its when you machine it things get bad.

do those chambers require less timing then?

I wish AA had made their new 914 head castings with modern chambers like those . Thorsten has done an amazing job .

Ooooh Walter,
Just another question, How thick are your cilinders at the head.
Made mine for 100mm pistons, 107mm at case and 113mm at the head.. But this is not turbo.

My 102's also now have been machined to 6,5mm wall thichness, but for N/A you can go much thinner, especially with these Deutz things.

For reference: the 98mm AA birals had 3,4mm wall thickness (cast iron) and stayed alive at 100hp per cyilinder!

The chambers help probably, but I think the most benefit comes from the twin spark 8)
