hey all, just pokeing around and seeing what you all would have to say about the removal of some of the matirial from the inside of the manifold.
 what i am looking at doing here, is the removal of the matirial (the big blocks in striped black) and smoothing of the area in red, and to gasket match the inside edge, and geniraly smoothing out all of the rough crap from the sand casting.... but before i do this i would like to know WHY the yamaha/toyota engineers put this here (both the blocks, and the sloped area in red). i am thinking that it has to do with dialing the power band of the 7a.. the sloped section i am thinking has to do with evening out the distribution of air to all 4 runners, and that the big blocks of raw aluminum is there to do nothing more than to take up volume. thus reducing the total air volume of the inside of the plenum... and in turn chokeing the 7a's ability to breath at higher RPM's.. just a theory. if my theory is correct than is my assumption also be correct that the removal of said blocks (and thus increasing the air volume of the plenum) would help the lil 7A to breath better in the upper RPM band, and in turn give more HP (since the 7a run SOOOOo rich) please correct me if any of my assumptions are incorrect. as far as the out side i will simply be removing the crap casting lines and clean it up cosmeticly, and then give it a good wrinkle coat. please tell me what you think.. depending on the responce i will address my plans to remove the matirial on the inside. -------------------- |
