Greatest feat of Engineering
Not sure if it is possibe to take a poll on a forum, so let me just pose a question. Which was a greater feat of engineering....... Putting a man on the moon, or designing an airbox for a G9?
I just got a used airbox off ebay, (I bought a cart that didn't have one) and I cannot belive all the ins outs ups downs twists and turns that the air travels before getting to the carb. Does anyone have a good explaination for this? I think Cedar Point should hire the same engineer to design the next super thrill ride. |

Re: Greatest feat of Engineering
The "enjunears" wanted the air tired and bruised up by the time it got to the carb by making it hit all those twists and turns, over the hills and through the filter to the carb.
Really, I don't have a clue......... |

Re: Greatest feat of Engineering
The airbox design on a G9 was created by an engineer named Moris Sputner. It was designed to create an air flow staggered matched with the new paper fibers of a new type air filter containing a micro filtering system foam wrap. It was also designed in conjunction with the fuel system to properly deliver fuel to the carb. by creating a precise vacuum that would continually flow through diaphram operated fuel pump used in testing NASA satelites. The float in the carb. was also designed around this and contains the same shape as the plastic insert in the air box. This supplies an extra burst of air/fuel when the throttle was at 3/4 open. The front box type area of the air filter box somewhat wraps around the front portion of the starter/generator and gathers heat at first warm up operation of the cart. Its design also pulls a magnetic field from the starter/generator and forces it into the micro fibers of the foam wrap which helps purify the air/fuel mixture intering the cyclinder right before detonation. A spacer was added within three months of this project design to help limit the back pressure created by the airbox. The airbox and new type filtering system was creating so much power that the carb. and/or muffler was sheering off the steel pins that held them in place. A tin sheild was also added under the seat of the cart to keep engine parts from possibly flying into the rearends of the testers.
If you need to know anything about any other parts or designs on these Yamaha's, be sure to let me know. |
