I read somewhere on a post here that the problem with some single intake manifolds was that there wasn't enough pressure for the following cylinders on the low end to produce torque.. i think it was azheat who said that.. but when i went o z32power... i read that he incorporated a pressureized tank.. is this to combat that loss of pressure when the sequential cylinders fire and suck up all the pressure.... wow i sound kiddy like.. but anywho. I just read nixits post above about that 3d image.. and i see where he didn't take into consideration as far as vacuum lines and stuff. Hey this green newb sign ain't just for show.. lol
