There is very little talk of engine internals. What results have been found with porting and bench flow work (ie. radiused valve seats)? Results with other marques have been good considering that much of this work does not effect emissions. Some dialoge beyond the parts swapping level might be interesting.
Speaking of parts swapping, some indepth results such as what have been the results of corner braking with just a front brake mod? Is proportioning off?
Cold air intake mod in sub freezing conditions on startup?
