Only oil temp data recording device I have is the video and my brain.

Rev limit unchanged, 7.5K.

80k on the engine. I would estimate 2500 track miles, and a lot more general hard driving miles. If I cant use the power I almost always run it in a higher gear around high G corners to reduce engine wear and oiling issues. I also try to warm my oil before I take the revs high. Apparently it wasn't enough.

Yes, I F'ed up not leaving the track immediately. Was kinda struggling to absorb that I just blew my engine (never done that before) and for some inane reason was trying to coast it back to avoid a tow until they meatball flagged me and I gave up. I know that's not a good reason. After I stopped the oil thing immediately occurred to me and I felt like a total douche.

Oh and the gloves... those are go-karting gloves I snagged at the go-kart track in Dubai. Work great lol. I do own a pair of SFI approved but seem silly to wear since I'm not in a suit. Tho unburnt hands would be better than burnt hands.



Back on the subject of the thread, I have been in contact with Brian at Valkryie Autosport and he has been very helpful in working to figure out the best solution for me. Once we have a definite plan I'll update. Thanks for your time so far Brian.


Until then, thanks for the ideas, compliments and the constructive criticism.
For the new build, please install an old-school mechanical oil pressure light switch (32psi should be commonly available) to a big red light in the cabin so if the oil pressure drops 'cos you have surge in the sump, then you can get out of the throttle to drop engine load and hopefully save the engine.

Alternative is AccuSump or Dailey dry-sump (and if Brian says they are 3.5K US I'm getting one - I was quoted 6K US$ 18 months ago, maybe because I am in OZ, I got the special "Export" price).
