after a couple of months of planning and parts collecting i have finally started my transzilla build. it will using a normal 914 side shift trans, with a few up grades, i will be dialing in the ring and pinion back to spec with this build also.
i laid all the parts out on my assembly table to give you guys an idea of all the parts installed. (IMG:http://www.914world.com/bbs2/uploads_offsite/i722.photobucket.com-12492-1362881754.1.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/i722.photobucket.com-12492-1362881754.2.jpg) |

now for testing. because i dont have a lot of fluid dynamic experience i needed to see how my calculation worked out. i wanted to put it all together and bench test it. once it is installed in the trans i wont be able to see what its doing so i needed a good visual and take some load measurements.
heres the setup (IMG:http://www.914world.com/bbs2/uploads_offsite/i722.photobucket.com-12492-1363359997.1.jpg) the inrush current is 9.5 amps and the run current was right at 8 amps. (IMG:http://www.914world.com/bbs2/uploads_offsite/i722.photobucket.com-12492-1363359998.2.jpg) i needed to see the difference in spray patterns. this is the flow for a rounded pattern. (IMG:http://www.914world.com/bbs2/uploads_offsite/i722.photobucket.com-12492-1363359998.3.jpg) and this is for a more of a fan type spray. (IMG:http://www.914world.com/bbs2/uploads_offsite/i722.photobucket.com-12492-1363359998.4.jpg) i decided to go with the cut off rounded style for a couple of reasons. because i want more oil flow and dont really need it to shoot any distance. i want to flood the areas with cool oil to absorb as much heat as possible. and with the crimped fan like pattern the pump pulled two more run amps. since the pump will be on when ever the ignition key is on (via a relay) i want any unnecessary load on the pump so it have a long life. |

i dont have a lot of fluid dynamic experience i needed to see how my calculation worked out. hehe, Doug, bench test looks good to me!! (IMG:style_emoticons/default/biggrin.gif) and i have taken fluid dynamics, two sections of it and the lab! your hands on experiment matches with the theory too, smaller atmospheric exit diameter creates a larger exit pressure, requiring more load on the pump, all the while ejecting the fluid a larger distance from the exit tube. Good job Doug, test successful! What kind of preliminary calculations did you do?? were you basing the system on a specified cycle time of your liking to calculate the rest (flow rate)? Love this thread man, looks awesome, and very informative for those of us who dont know much about the internals of the trannys, even what they look like.... Besides the HB gear you have in there (which you may switch) are all the other gears stock sizes? |
