I have a question for knowledgeable and professional people in this field. Why once the engine is in WOT, the RPM's goes down and then rises back again in almost all engines? Is that something positive or is something that can be addressed, and btw. Does it has a name that behavior? Thanks in advance.
In a dyno test, they go full throttle and then load the engine. It's exactly what it sounds like, they replicate real world conditions and put resistance on the crankshaft to simulate how it would be in a real car. When they load the engine rpms will drop slightly before the dynamometer let's the engine ramp. Ramp speed of the dyno is adjustable too, typically a slower ramp speed gives more accurate data, with increased risk, as you're having the engine under 100% load for a longer period.
Pretty sure it's the strain or load put on it by the dyno, but I don't know for sure. The engine loads down under the effort before revving all the way up.
Its the dyno. That's how a dyno pull works. The water brake servo pulls/loads the engine to the lowest rpm of the test sweep, then releases slowly to allow the revs to increase to the programmed highest test rpm. It does this at a programmed acceleration rate, typically 300-600 rpm/sec. Which bring us to another proof point why this ain't hitting 12k rpm. Listen carefully and look at the video time stamps. The water brake begins the rpm ramp at about 10.5 seconds, and the pull is complete at 14ish (hard to grab exactly with the RUclips stamp. So a roughly 4 second ramp. At a 600rpm/sec test, this pull did not have enough time to get to 12k rpm because the pull began way below the 8100rpm torque peak. Most dyno pulls are about 3000-3500 rpm sweep. The video title is BS.
I see a tunnel ram, we are told it's a chevy LS. We don't have a description of the cyllinder head. I'm going to imagine the CR is around 14:1. That displacement is somewhere between 427 and 454 cubic inches to make the 663 ft-lb. If it's only 400ci making 663ft-lb that is completely outstanding and not "normal".

Small pistons are terrible for high revs, because they can't fit large enough intake valves. It's why the Ford Modular is such a turd without any boost, while even the 4.8L LS is solid. Hell, people takes the 4.8 crank into a 6.2 block, and make it into an evil frankenmotor.

@@Stale_Mahoney The formula for 9k+ RPM LS motors dictates a large displacement block such as a 6.0 or 6.2 block, high flow heads based off the aluminum block variant, a crank from a 4.8, and custom conrods that corrects the piston to deck height.
"You can make it spin that fast but it’s not making torque anymore." Peak torque at 8100 rpms. Peak power at nearly 9000 rpms. This run went to "only" (a term im using loosely here) 10,500 rpms. Not the "12k" the title implies- but still impressive.
