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.... |

I had various ideas on where to put the TB, but when you factor in weather protection, cable position, plenum simplicity, air filtering, etc, it made sense to put it on the side. I was also trying to maximize length of the runners. If I made the whole thing shorter I could have more easily put it on top, but it would have shorter runners and a smaller plenum. I have the runners at a length that allows them to resonate at the torque peak of the engine.
My goal was to build a good street system. Most people are doing this for racing which is a different set of priorities. I also did not want to cut anything on an original six to make stuff fit. So far all of my mods to the car are reversible and I have all of the original parts. The cage ideas might not be so easy to do with low impact! |
