It's not the power he's griping about. It's the amount of power per psi. Basic laws state the best you can hope for when boosting is to double the engines original output at 14.7psi or one atmosphere. In this case 824hp at the flywheel. Then pump loses and heat rise will drop the actual output. In a perfect world 824 would be the highest possible output. At 18 psi the engine is at 248% it's original output. Impossible without the ability to change cam timing.
It has to do with intake wave pulse tuning. Google it for more in depth explanation. Hours of fun reading. Intake pulse tuning is why cams and intakes change power levels, and their rpm ranges. When a cylinder is filled, the intake valve opens, vacuum draws the charge in, intake valve closes and then boom. What some people over look is what happens next. When the intake valve shuts, all that air that didnt get it, back ups behind the intake valve causing positive pressure in the intake runner. Now this pulse will back up at the valve, and eventually goes backwards towards the plenum. If the intake valve opens at this point, the cylinder will be left to draw in what it can by pure vacumm as the piston heads to bottom dead center. As an engine speeds up, these pulses become more in tune with ea other. Intake will open then close, the charge will back up at the valve again, until this time, the runner is packed, but the puslse has not changed directions and the intake opens again forcing the charge in as the intake is sucking. This timing is why 4 stroke engines make more power as engine rpm rises.
Now what if you could have that max cylinder fill at all rpm? Boost is measured in the plenum, not the intake runner itself. 14.7 in the plenum, 18 in the intake runner when the intake opens. The intake charge will see more than one wave pulse after the intake closes. The first is the strongest and will make the most power. But not the one most engine are capable of using because of intake manifold restrictions. Most use the third plulse. So it actually hits the intake, bounces back to the plenum and back again. It does this a few times before the intake opens up. Usually the thrid time the pulse heads to the intake vale is when it opens. A gross over simplication, but the best I could do w my weak background.:lol:
