Because 800hp and 10.3 sec means ridiculous amounts of g's. It's a common problem mate do a search. In mine with 450hp anything less than 6l it surges.

Did you read this: "Up until 1 month ago, it had standard sump with the oil just filled to the top line on the dipstick, as you would with any car. When we changed the diff ratios, we installed a 9L sump and again filled it to the top line of the dipstick. WE HAVE NEVER OVER FILLED THE ENGINE WITH OIL!" - from Trent @ Mercury Motorsport.

Yea I don't think it's really a problem in a straight line mate, you mite have pump issues or running a oil that's too thin.

Yeah I did read that Trent thanx. Dean do u have an a/m oil pressure gauge ? It might surprise u :)

Yea I do mate, $900 worth of Defi's sitting on my dash, 8k limiter launches on 265 semi slicks........... No surge!

Just filled to the line, I fill it to the hump when i change my oil for trackdays. But general cruising round filled to the line, it takes around 6L because of the oil filter relocation kit and oil cooler, which is emptyed out each oil change.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
