air flow

gerry give us some idea today, he said we need test the air flow in the pipe, but the problem is the air flow meter can not test the exhaust air flow, because of the hot temperature, it will melt the meter, we can made a manometer instead of the air flow meter,but the first thing we have to do is install a ring in the pipe, and weld another two small tubes on each side of the ring.

install the pressure gauge and welding the gasket&adapter

today we still working in the workshop, we weld the gasket to the pipes and join to the adapter, also we weld the tubes on the pipe to connect the pressure gauge. as you can see in the photo, i bought the gauge from rosebank road, it really different to find the gauge, at first we went to repco, but they do not have the gauge, then we went to the BOC gas, they have the different gauge that we can not used, after that i went the rosebank road there is shop called "black..." ,i bought a pair cost 76 dollars. i am so happy i can find the gauge.

keep going in the workshop

today we still keep going our project, we extended the pipe, and i use the exhaust high temperature silicone seal the gasket we made~

new semester coming

after the summer holiday we come back to UNITEC, times goes very fast,we will do the modification today. The modification was done by removing the auxiliary valve, 4 screws, all air valves, brackets, gasket and O-ring. A steel sheet plate has being used with a silicone paste to seal the hole as we only need a throttle lever, butterfly and TPS sensor. The butterfly is located between a 1meter long exhaust pipe and it is control by cable which restricted the flow of gas (air) when the driver releases the accelerator paddle.
