Sam, are you speculating or do you have some results/indication that there's a lot to be gained from VVEL control?

Proof is in the way the VVEL system works in stock form. The cam duration is so aggressive at 300 that it causes valve overlap which in turn reduces boost and reduces power. Drop the cam duration and you'll be able to use more of the air that's entering the engine for combustion purposes which will create a huge increase in power.
Example, if a car is making 465whp on 93-octane at a 10.5:1 compression ratio (350z w/ HR motor) on the same pulley/charger that Sam offers in his stage 1 supercharger kit which only makes 8psi on our cars because of valve overlap, if we were to drop the duration to match that of the HR motor and with our 11:1 compression we would make more power then 465whp, and that's only on the stage 1 kit with the 14psi pulley (maxing out the C38-81 supercharger). The stage 2 kit would make ridiculous amount of power with the VVEL controller.
Just my 2 cents.
