Pre-oils on start-up and takes care of any cavitation issues you may have on road and track
I must absolutely totally disagree with using anything but a dry sump on an Ultima. When I first became involved with Ultima's, in about 2006 there where frequent complaints about main bearing problems with cars that were tracked, since then that has greatly diminished. I remember at one point responding to a blogger that basically said all American motors are crap, so what do you expect? My answer was that lots of sprint cars that don't have unlimited budgets will campaign for a season on 2 or 3 small block chevy's 350 cu inch 650 plus H.P. that's 2 or sometimes three nights a week 1 to 4 sessions about 20 minutes each 3 weeks out of 4 for 6 to 8 months. Every, without exception, every one of those motors is dry sumped. Why do you think Chevy went to dry sump on the Corvettes yes originally just the top end models, but now all models are dry sumped. It's not because its cheap. last month in a Q and A with Road and Track magazine the Chief Engineer for Corvette indicated that at 1.04 Gs on the base car that wet sump is not an option. Last time I checked an Ultima will do 1.27 correct me if I am wrong and that's on street tires. So in the end its your decision, but when you come back and say "oh my, the main bearings look like hell and I have no oil pressure.I for one will not be surprised. Lee

Of course dry sump is preferable, but the OP wouldn't be asking about a winged sump if he had the budget for a dry sump system, an Accusump will be a better bet than a winged sump as it is not affected by cornering G force.a four pint system will be good for most applications.
thanks for the replies but I was thinking about this system that I mentioned, to gain performance: I read that the throttle response becomes much more reactive and can gudagnare some horse ...
But I think depends on the engine type.
But now reading your responses I realized that I would have problems installing the semi-slick with my L98 for ig curve, that is more than 1.04 g??
with seeds slick will have even more traction and therefore more g cornering.
do you risk breaking my engine?
and so I should install Accusump??
thanks

i had not good idea semislick on my Gtr... If you are building a car and considering a dry sump isn't there the additional value of creating a car with a lower center of gravity with concomitant performance improvements by locating the engine lower in the chassis? That is, without a large/tall wet sump the engine can be lowered. For that reason alone I would go with a dry sump. Obviously in the case of an existing build, dealing with adding a dry sump to lower the engine might be more problematic.
