I have called it out before.

I have illustrated it mathematically before.

That engine / example is in no way comparable to our cars.

First, it's running fixed AFR, fixed ignition timing, and fixed cam timing.

Second, it's a large displacement, 2 valve engine on which VE peaks below 90%.

In other words, that is not comparable to our engine at all.

I'll bet anyone double or nothing the cost of a header and my dyno time, that I can bust that myth on a dyno on this engine, on this car.

I'll bet anyone triple or nothing that I can cut the power in half on a motorcycle engine with the same size dents. (has to be the right motorcycle engine. I'm sure you could practically duplicate their results with a Harley motor, but I digress.)

Your point about stock decatted headers is valid though.
