Talking to Adam the car was still making power and on previous runs was still making power over 8,000rpm and believes had he been able rev it to 8,000 on the 27psi run it would have made at least 480kw

Bit of and update

I had an issue where every time I’d boot the car it would trip the engine protection and throw an oil pressure code, we thought maybe the engine protection was set a bit aggressive. 

we took the car for a drive with a data logger going and fair enough it was losing oil pressure rapidly, put an extra liter of oil in it and presto all fixed. Which shows the protection was doing it’s job perfectly.

Lesson learned that even with a baffle in the sump it’s still not good enough, something better is on the cards at a later time

Great to hear that the oil pressure warning was doing it's job.

What sump, baffles and oil pump, what is the oil breathing setup, and was anything done around block oil returns or cam cover baffles?

Only oil mods are a tomei baffle in the stock sump and cam cover baffles and a catch can that vents to atmosphere. Everything else is stock cause it’s still a stock unopened r33 engine 

yeah that's exactly why I was wondering.

stock pump and not happening under sustained high revs means it is unlikely to be a "too much oil in the head" issue, just a "oil shifting in the sump under high g" issue....it obviously goes ok :) overfilling should be fine until you have a reason to open the engine

That’s what I’ll be doing, yes it goes very alright lol. Once i put it on high boost and gave it a boot in second I had to start grabbing lock to make sure it didn’t hit a gutter or tree or fence.

need to find some rear end grip or make the 4wd keep up with the car or both :/ 

Have you binned the Hicraps system yet? Like properly bin it with a full kit where you remove the Hicraps ball joints.

That made a massive difference, and also dialling in the traction rods.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
