What kind of intake manifold is that?... i also notice that you don't need your air pump in there.. theres no belt to run it... and if you do run that air pump... take that autozone air breather out a there its restricting... i had one on and replace it back with the regular hose that connected to the intake box and my car actually ran better...

 

carl, remember that was at WOT 1n third gear, i pulled the filter and hit it again and it spiked to about 1'' when i dumped it then fell immediateely of to 0'' and i almost wonder if that wasnt siphon effect, the filter looks a little small for app, check it out in the rx7 photo club

 

that set up lasted 2 miles before I pulled over and cut the belt off, the airpump sounded like a damn procharger.
