Yes the flat plane crank seems to be well discussed.


The RPM limits are much higher but to my understanding at a cost to overall reliability?

Has anyone seen the latest Hovemann Hillclimb video?

9000rpm LT5 sounds amazing with the flat plane crank!

The LT5 in that Opel does not have a flat crank. All flat crank V8s sound like four-cylinders and the difference is obvious, unless, of course, you're deaf. The reason the sound is different is firing impulses are coming every 180° rather than every 90°. That's the same as a 4-cyl.
