He's either put in a desmodromic valvetrain, or the idle speed is also the redline.

That didn't work.
To some extent, yes, you can measure the torque at different degrees and on the "downhill" side of a lobe you will get about the same force pushing on your torque wrench as you had on the same spot going uphill.

BUT, the valves themselves are reciprocating, and have mass, so that the faster you spin the camshaft, the more force it takes to jerk the valve open, which is lost energy. As well I suspect that the springs do not return as much energy at higher speeds as they have to use some energy to accelerate the valve in the closed direction.

Well the first red flag was "double or more the economy".

It didn't get any better after that.

I don't think this is correct, Frank - the valve stems don't act on the cam to keep it in motion, the springs only act as a way to keep the valves seated and closed unless the cam is acting on them. This is part of the reason that solenoid engines are so much more efficient (not by any means 50%) than cam driven engines.

thinking i might have to convert my engine

but think about it, going from 150lb to 15lb is only a 90% reduction. what a waste!!!

thats why 2 strokes have the best powerbands, no valve springs...

in addition, i found this product to further enhance my efficiency and performance Piston Return Spring - $14.99 : KaleCoAuto, Hard to find automotive items!
KaleCoAuto piston return springs FORCE the pistons back into the motor, no longer relying on gravity! This effectively increases your revs, horsepower, and peak torque!
