Lower pricing, and 370Z support to Pro Tuners

BMW, Toyota, and soon honda will all have continuously variable valve lift systems out in the next year. BMW had it first a year before NISSAN but the BMW system is limited by it's crappy and huge design to 6,500 RPM. The NISSAN version is good to over 8,000 and while it is still brand new the new toyota version looks to be equal to the nissan system. the new honda version I don't know to much about yet but it looks promising as well. All of these systems achieve the same basic end result with differences in max rpm, max lift, min lift, and complexity. Our system works great with good lift a large range and high rpm's but at the sacrifice of lubrication and friction. The toyota system uses a traditional camshaft but uses a special rocker shaft that his a lifter arm and pusher arm arranged like < that can change the angle between the 2 to transfer more or less of the cams motion to the valve. This only changes lift and not duration but it should be possible to replace the main cam for more power which you can't do with our VVEL. Food for thought it's out there and it's big shouldn't be more than a year or two before the american companies copy toyota again so there will be more demand for tuning these systems.

Maybe you need to dumb it down for me.

In trying to break down and decipher what you wrote, my interpretation is the lift can be changed on the Nissan VVEL. Basically duration controls where peak power will happen in the rpm range but addition lift increases peak power at that particular point. If we can increase the lift and the heads flow efficiently at the higher lift level, then peak power will increase on a assumptive basis.

It's my opinion from material read prior on head flow numbers, the 370 has some pretty killer heads.
