I don't remember if "Bluegrass" mentioned the high speed retard chip included in the computer timing system. Or at least the MSD system we use on the dyno has that useful feature. It is interesting to experiment with how timing changes can affect WOT performance. We also use an adjustable timing...
It is simply not possible to accelerate the valve more rapidly on the way up to maximum RPM, than it is accelerated while operating at maximum RPM.
There is a useful form of valve float which I refer to as valve "loft" and it can improve performnce when used in a controlled manner.
