After recently buying my S3 I am now started to sort things out with regards getting a good basis to improve the power to Stage 2.
Started things off today by giving the injectors a once over so here is the process :
Initial ultra sonic cleaning to remove all the "gunk"
Into the next ultra sonic cleaner after all the initial dirt has been removed
All hooked up to the tester to visually observe the spray pattern which was pretty good
Next was a leak test which I forgot to photograph but no leaks were found up to 7bar.
The injectors were then fired for 15 seconds to observe if they all emitted an equal and correct amount of fuel
For some reason the next few photos failed to capture properly but the results showed that 2 injectors were down and 2 were good. this process was repeated a further 2 times to ensure it was correct. Again the same 2 were confirmed down. Filter baskets were then removed and placed into a Third ultrasonic cleaner and electrical connectors which cycled the injectors to ensure all fluid was passed through the injector body and nozzle. This process was repeated several times with the injectors being retested until an acceptable result was achieved with all injectors producing the same volume of fuel.
The new filter baskets and seals were then installed
Finally, all done and ready to be re installed
Now I know the injectors will not be causing any problems soon
