  1. Wasn't so much about spinning or centifugal forces. I probably shouldn't have used the word rifling. More about breaking up the uniformity of the hole by having a channel to one side of it. If you pour oil down it, the majority will go down the larger portion of that hole and air will come up the channel. So the theory is to promote this action and perhaps have faster oil return.. I'll have to find a youtube on it to explain it better.. but yes, you're right at the end of the day probably too hard to pull off vs the benefit.
  2. No you wouldn't.. you'd dry sump it. Look within - you know you would. Just a completely side question for the engineers here. Has anyone thought about 'rifling' the oil drains? Essentially like making a keyway down that hole? May not be easy to do I am not machinist. But I have a faint memory from physics days that this may actually be more effective than drilling out by breaking the surface tension and allowing a pathway for air to travel up alongside the oil trying to get back down.. ? having a perfectly round hole promotes the oil to keep the hole 'blocked' so to speak. Thoughts? Or am I talking rubbish?
  3. You will almost certainly have oil surge problems doing 61's at Barbagallo in my opinion. Even with all of the Wet Sump mods in these preceding pages. Maybe consider adding an Accumulator as a band-aid.
  4. I'm at 500kw at the hubs and use for circuit, and Tarmac Rally. I'm in Perth too. If you go to Collie (and you definitely should) it will be all left handers. Come do a Rally Sprint and watch your oil logs go nuts even with all the wet sump mods. If you're building a serious time attack car go dry sump and don't stuff around ever again with it.
  5. I can't say I have done it - but I am of the same opinion - I wouldn't do something that weakens the block. An external drain is attempting to get the same result - just like a jerry can has a breather.
  6. Question! Who has used a TurboSmart replacement BOV that fits in the OEM position? And if so has anyone actually noted a difference? There appears to be a suggestion the factory one may leak - but I don't know if that's true or not. I don't see how I can measure either - so the only way to find out is replace and see (which is an expensive experiment if it does nothing) And Turbosmart appear to offer two variants: https://turbosource.com/products/turbosmart-kompact-shortie-plumb-back-efr-bov-upgrade https://turbosource.com/products/turbosmart-kompact-shortie-dual-port-efr-bov-upgrade Any feedback ?
  7. Wow really? I don't think I would like a sump resting on, or chafing on, the subframe like that. Ironic that you would put a dry sump in for ultimate reliability in oil supply, and then let something like this through.
  8. And made a little more room for center scavenge.
  9. Had same issue - but did something about it.
  10. Well.... everyone’s being trying to stop transmission of late so...
  11. The 4.375? Nope - still got front and rears (the rear includes a full GT-R diff housing, but no diff).
  12. If nothing gets in my way (and plenty is trying to) I should have a result this weekend.
  13. Yeah have to say I had similar with my 8374 a few years ago and was also disappointed with little casting dags on my 8474... They could be better finished given they are the premiere models in Borg Warner’s line up..
  14. Good grief... you're right. Problem is that if you google "Matchbot" using Chrome in Australia, the first link takes you to this 'old' one. BW need to take that down.. would take 2 mins to do. I even have a response on FB messenger from them apologizing but they don't know when the new turbos would be up on matchbot (that was 12/12/19, so only 4 weeks ago.. ) If their own people don't know its up........... : /
