Oil surge on drag launch

Oil surge on drag launch
Here is a log from a 11.5 sec run in my Mirage.
60 ft was 1.69 with full street tyres and normal tyre pressures.
Is this common for Evo's?
I'm running a stock evo6 sump.
Oil level was "full", not overfilled.
I will be overfilling it at the next meet and relogging to see what it does.
Oil surge was not present on a 1.80 60ft.
Cheers, Mike

the pans arent baffled good enough to keep the oil in one place, so ya it can slosh around a lot. Maybe try putting a kiggly HLA regulator on it and retest? or contact Dave Buschur to modify your oil pan with better oil control

I'm running the kiggly HLA at the moment.
Sending my sump to the USA from New Zealand isn't really an option (cost $$).
I was just wondering what other people do, i've seen a lot of 10second (and faster) evo's on this site and wanted to know if they actually modify their sumps.
But in saying that, most people wouldn't log oil pressure so they probably wouldn't know if they are getting surge or not

I'm willing to bet most of those guys have the issue, but like you said will never see it because they dont have the logging equipt to see it. maybe look into a local guy who knows and ask him for some advice. theres gotta be someone there that has modified their pan before.
have you done any testing with and without the kiggly unit? id be very interested to see how much difference it makes

Your data looks similar to what Robert from FP posted a long time ago and why he insisted on running a new oil line (high pressure) to the turbo, rather than the factory line coming off the head. I believe it is a common problem for cars pulling some solid g's. I'd suspect there are plenty of places near you that could help rectify your problem.

yeah there are lots of places here that can help out, my tuner being one of them. I've just never heard of people getting oil surge on such a "slow" car.
My 60ft times are nothing spectacular, imagine how bad it will be with semi slicks on it >.<

here is a log from the weekend.
195/55/15 semi slicks (Advan A048 front and Potenza RE55S rear, 18psi)
11.39 @ 190kph (118mph) with 1.60 60ft.
oil level was overfilled, about 6-7mm above the "full" indent on the stick. Not too bad considering the 60ft time
