Oil Surge & Accusumps

[vern]

Do any teams use them or any other oil accumulators to prevent oil surge? I understand that a nice tidy way to prevent oil surge would be to run a dry sump system but that is impossible at this late stage in the build. Initially we were going to simply insert some baffles in the original sump but I am doubtful of usefulness. I have been looking at Accusumps (http://www.accusump.com/) because quite a few kit car enthusiasts use them as a cheaper method of reducing surge when they bolt a motorcycle engine into a 4 wheeler. However I am having trouble:

a) Finding reliable information on their effectiveness
b) Selecting the right spec ( eg is an electric controller valve worth the extra money)
c) Finding more than one supplier in the UK to make sure we're not getting ripped off

Any thoughts would be appreciated,

Good friend of mine has one. They are worth it if you can't go dry sump. Cheaper than a blown engine during the endurance event. http://fsae.com/groupee_common/emoticons/icon_wink.gif As for the electric solenoid....get it. Anytime you leave something up to the driver to do during teh middle of a turn....it won't get done. You can buy them from Pegasus Auto Racing's website. They WON'T rip you off. I think you cna also buy them from Canton (the manufacturer) directly. Hope that helps!!!

OK, thanks, and the electric solenoid valve is a bit more trick as well rather than a mechanical valve http://fsae.com/groupee_common/emoticons/icon_wink.gif.
However i'm from Cardiff in the UK and shipping costs and delivery time is an issue from the US. Any UK teams run Accusumps?

I've considered several methods to take care of the oiling issues, and of course my preference would be to dry sump. There's not enough time or support to do it at this stage of the game, so my second choice is to try some pan baffling. I, too, am skeptic its effectiveness; however, the lightest accusump type setup that I could find was 8 pounds for the system. When we're working to lose ounces on so many parts, it's EXTREMELY hard to justify 8 pounds if it isn't absolutely necessary.

The F4i has improved top end oiling compared to our old F4 top end we had problems with, and I hope that coupled with some pan baffling will help to remedy the oiling issue. I'll find out soon enough how it really works.http://fsae.com/groupee_common/emoticons/icon_wink.gif

a) Tons of autocrossers use the accusump without issue, I suspect the one quart setup would be more than adequate for our engine size.

b) Electric valve would be a requisite for me, otherwise it's another thing for the driver to forget and the team to worry about when prepping the car.

c) Can't help you with UK suppliers, but there are a ton of places here in the US that sell them. Canton is just as competitive as any others I've seen.
