baffle screws safety wired
Will the screws that hold the baffles in place be drilled for safety wire or will they be self locking? I won't trust Locktite given the high oil temps the Z will see.

I can include drilled bolts. I like the idea of them too... even though the bolts would never fit through the oil pump pickup, and there are countless other non-wired small bolts in the crankcase LOL

P1010949.JPGP1010948.JPGIt is not likely that the baffles would be removed very often so locking fasteners would be good to do the job of safety wire in the instance. Here are pictures of a couple of flange locking bolts that are available.

I ordered some pre-drilled screws to try out that will be here Monday. I wouldnt want to have to drill those little holes in those screws! They dont have the flange in them, my supplier doesnt carry any pre-drilled with flange or locking flange. I will supply the stainless wire for it also. For the screws I went with Black-Oxide alloy steel since its tensile strength (170,000psi) was more than double the prettier stainless variant (80,000psi).
They are 10-32 thread and 1/2" thread length. The prototype baffle top plate was .115" thick but for production I am going .060" to make it a little lighter. Well actually I told the laser cutter to play with it and if the .060" felt flimsy to just use the .115". The thicker plate is 9oz and far more sturdy than necessary, so I figured on going lighter and a few drops more oil capacity with thinner plate as long as its still sturdy... I left it up to him. He plans to cut the baffles tomorrow, so I might have them by tuesday or wednesday. |

I have no idea! I take it to 82-8400 rpm all the time and other than the normal bolt ons and tune, its all stock. 24000 miles on it at this point.

Probably LOL. I will play with it and check it out. Just waiting on the baffle plates. I am on his ***. Dealing with vendors is so frustrating!!!
The wire and the drilled screws are here, and the pans are pretty much done. Just have to start adding the oil drain ports for those customers. I havent done it yet because I am sitting on the fence thinking about using a NPT thread about the same size as the -10ORB because I think it might be better for most customers. I dont generally like NPT threads, but I think customers might like it better for tightening and feeling good about it being tight and leak free.

2 Photos attached... 1 showing the pans are done machining other than oil drains.
Second photo shows the baffle top plate that is being made. I added the vertical wings and positioned them so that they will focus all the oil coming back from the rear of the engine / upper pan area into the sump area. They are positioned to recover most of that. Their exact position will make more sense when I post pictures of it with the upper pan attached from the inside. My thought process on this was lets try and almost take the side wings of the lower pan out of the equation so that oil can recirculate more easily. With oil circulation mostly bypassing the outside wings of the pan, these wings serve just as oil displacement and as surge protection where oil can easily travel from the wing to the sump, but oil can only really get into the wing through oil level, which means there was a surplus of oil to spare for storage in the wing. I hope I am describing this in a way that makes sense. Basically I wanted the baffle system to not be a full time part of oil circulation, but to mostly act as walls and reduce sump area for oil to get away, but then these walls are also check valves to allow stored oil in the wings to enter. |

Its really easy you just connect the 6 bolts together by running the wire through the holes in the bolts, easier than tying your shoes. This way they could never spin out. It actually doesnt even need wire anyway, its just a racey precaution.
