Pyrometer?

I guess with adding the regen cycles and extra heat they needed to add some active cooling on the turbo. So what is the gallon capacity of the radiators on these new 6.7's?

Yes, my turbo apparently has a water jacket around it.

It might be a factor of less coolant capacity in the actual engine block( if the blocks are similar then the cylinder space had to come from somewhere), and plus a turbo doesn't add much more coolant to the system really, maybe another quart or so... obviously depending on the size...

the actual block is a bit larger to handle the increased size of the holes. . .I guess the coolant loss may come from where the cylinders are siameased 1-2, 3-4, 5-6.

What I believe Drew means is something that is done on quite a few inline engines for space saving and rigidity of the cylinders(I know it was done on Datsun 280ZX...). What they do is put the cylinders a little closer together (or not, depending on application), and not have a coolant passage between them (or at least not the full length of the cylinder), so the 1-2 siamese looks like an "8" where non-siamesed are "o o" with space. If that makes sense...
I have heard that siamesed engines typically have problems with cooling... I hope that doesn't become a problem on the 6.7L when adding power...
