for my 2316 it seems that the stock plenum might be reaching it's limits as far as volume goes.....so, I either fabricate a larger common plenum, or go with individual throttle bodies such as TWM or Jenvey*

single plenum would be easiest, but the individual throttle bodies look better (IMG:style_emoticons/default/smile.gif)

has anyone switched from one to the other on the same motor with everything else being the same???
