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??? *Jake Raby is the U.S. distributor of these.... |

it took me 1.5 hours to get home tonight due to traffic and fog...during that time I talked to Sir Andy for about 20 minutes about manifold/plenum design and the rest of the time I spent thinking how the heck can I make something just like the Porsche Motorsport plenum for my /4 (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) it looks to be all one piece, how do they make a hollow c/f or 'glass part like that?? could you make one from wax, cover it with the carbon fiber and once cured, melt the wax out of it?? with the intake like the GT3RS, one could easily take the plenum off to test it with the throttle bodies exposed directly (add air horns) and you could also keep the plenum on the throttle bodies but remove the butterflies and install 1 single throttle body on the opening of the plenum...3 different methods of induction with one basic design (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) |
