Lingenfelter Flat Crank LS - engine dyno
Ever wonder what a flat crank LS engine would sound like?
Found on Lingenfelter's forum:
"Here is a dyno video from last night of the new Lingenfelter 358 CID LSx flat plane crank race engine for our new white Gen V Camaro SS. This engine is putting out 621 horsepower @ 9,000 RPM running NA.
Next up installing the 76 MM Garrett turbo!"

Balance shafts can limit the vibration but they are very rarely used in racing applications.
They also have a much shorter stroke than your typical cross plane crank. Which is why this LPE built LS is only 358ci.
BTW, production cars DO use them, but those are Ferrari V8s and other exotic V8s.
The flat crank is part of the reason Ferraris sound the way they do.
Personally, I think it sounds pretty mean.
I wonder what it would sound like with a meaner cam.

The one on the right is a flat (or 180*) crank:

Here's an illustration (that I found on corvetteforums) that better details the differences between the two:

The way I see it, it has its advantages and disadvantages but either way I think its cool as hell. I just cant wait to see that 2010 Camaro flying down the road sounding like a ferrari. It can't be that bad, Ferrari has been doing it forever and their newest 458 Italia has a very powerfull V8. Maybe I am bias because I'm half Italian. A closer ratio trans will be chump change for Lingenfelter and thats all they need with this kind of motor.

I think it sounds awesome.
And yeah, from what I understand, it would require a custom cam.
I'd like to see what Lingenfelter or someone else could do with this crank and a dedicated NA build.
I bet it would be pretty insane.
