yet another oil tank thread, vellios vs oe Options

[blabla914]

I'm purely interested in the oil control of these two tanks under high cornering loads.

I have a vellios tank purchased from patrick motorsports about 3 years ago. I understand some of the EARLY vellios aluminum tanks had oil control problems, but it was fixed quite some time before I bought mine.

However, at the last autocross I caught my oil pressure gauge jumping around. As I came off a medium speed (about 4000rpm in second) corner I saw the oil pressure gauge make a BIG wiggle. I took it a bit easier the rest of the run and I didn't see it do it again. The car had been idling for at least 15-20 min and had roughly 170F oil temp. I also ran the motor at like 2000rpm in staging a bit to make sure the scavenge pump had a chance to empty the case. I verified the level after the run and it was overfull. I can't get the hang of adding oil to this thing to save my life. It's usually a little low when I show up at autocrosses (it's generally the only time I check it, but I autocross quite a bit) and I always add too much. I'm worried it's doing this when I'm not looking, which is normally the case when I'm trying to look where I'm going. I've been trying to keep an eye on it, but it can be tough to push the car real hard when you're looking at the dash, and it seems it doesn't do if unless I push real hard. Know what I mean?

I am further worried by a tech response I saw a while back in the panorama where a guy wrote in saying he had popped his -6 at the glen. The first question the tech guy asked was if his car had the factory -6 tank. He didn't necessarily ask if the tank was a vellios, but he say that the factory -6 tank should be adequate for what he was doing.

My car has a pretty standard setup with an aluminum tank, no front cooler and -12 aeroquip lines. It's hooked up to a '69 2.0L motor that is mostly E spec. and I use a 7k rpm rev limiter, but shift at 6500 rpm.

I'd be interested to hear from you guys who are running on the track or autocross with the aluminum tank that fits in the stock location. Any pickup problems? Any tricks I should know?

Thanks for your help.
