Re: V12 LS latest
I wonder how it compares to a 511 tall deck V8 in power and efficiency? It's hard not to like a V12.

I saw that car at SEMA last year. The entire build/engine was first class.

I saw TWO of these behemoths at SEMA this year and captured both of them on film. Even got to see/hear the Camaro leave, and I'll tell you, it sounds just as good as it looks!

Re: V12 LS latest
Since a was a kid I always loved V12 motors!
To this day when I see one I bet my face probably looks like this!

Re: V12 LS latest
What does the 8.80" (bore pitch X 2) extra length and offsetting the pins 30 degrees do to the crank stiffness? Certainly moves all of the harmonic orders around.

Re: V12 LS latest
I'm sure it's more prone to twisting. It doesn't use split pins though. It is an odd firing engine
Re: V12 LS latest
Nice picture, thank you. Is it like two V6 (4.3) cranks lined up? Does anyone know firing order?SHARKBITEATTACK wrote: ↑Sat Nov 11, 2017 5:57 pmI'm sure it's more prone to twisting. It doesn't use split pins though. It is an odd firing engine
Re: V12 LS latest
Thanks a lot Ken, very good information there. So it's odd fire (30° & 90°intervals), alternating cylinder banks in each fire.Kenova wrote: ↑Sat Nov 11, 2017 8:27 pm Here's a page with the firing order.

Re: V12 LS latest
I am with you. I have always had a fascination with the V12. However my pocket book does not match the price.

Re: V12 LS latest
Crank looks just like a 6 cyl in-line but with very wide mains.
As far as firing order is concerned, if you treat each bank separately then each bank is like 1-5-3-6-2-4 in-line 6 cyl firing. Left bank is 3 RHS power strokes behind the right bank but same firing order if you think of that bank only.

Re: V12 LS latest
AFAIK all V6 currently in production are 60° bank angle with 60° offset pins (Toyota shown below), or (if based on V8) 90° bank with 30° pins. None are odd fire.
In my opinion the V6 is safer with very low journal overlap due to the relatively short overall length = stiffness. Overall length of a "V" design between 1st and last MB is typically (number of cylinders per bank) X bore pitch + 1 rod journal width.
