Special Oil Systems

[Bowtie Man]

Hey all,
After completely anhialating our gixxer at a local autocross event, i'm wondering how many teams out there have developed a custom oiling system to compensate for the lateral G's a bike doesn't see. I would assume the bikes are designed specifically for leaning on cornering so the oil would push to one side and possibly away from the pickup. So i'm thinking that a swiveling oil pickup may be an idea but I just want to know what has been done out there.
thanks

Luc

We run the F4i with a custom sump, including some heavy baffling. I think this has left us without any oiling problems. Did your car have a stock sump? Or any sort of baffling?

Most teams do one of the following:

Overfill the stock sump
Install a baffle of some sort
Use a swinging pickup (we've done it the last several years, with our own low-height sump)
Use a dry sump system

First step-

Log your oil pressure.

absolutely the first thing you should do! i designed the dry sump for our 05 car and am designing the one for the 06 car. it prevents starving the engine of oil and lowers the COG considerably. be careful if you follow this root that you have NO instant gasket on any sealing faces because the dry sump pump will happily remove it. even if you have filters to protect the pump they will block and you'll seize an engine (lesson learnt!!). our 05 sump was 20mm, and our 06 is going to be a tiny 10mm http://fsae.com/groupee_common/emoticons/icon_biggrin.gif

Denny, you got any pics of your swinging pic up? im curious, thanks!

Should you be concerned with instant gasket period or only with dry sump?

you should generally never use instant gasket, but its ok if your not using a dry sump. the problem with a dry sump is that it creates a vacuum inside the engine in order to scavenge all the oil. if instant gasket is present it will suck that up too!

[Agent4573]

I've seen many sump screens completely clogged with the remnants of instant gasket and RTV sealer. I would highly recommend staying away from it as much as possible in the oiling system.

Just to add to what Dwayne said about our car, initially we just ran the standard sump, overfilled as Denny said and only with minimal baffling. We ran that setup for 3 years no problem. Then we went to a custom shallow sump, when we first got on the track the oil pressure data looked like the lateral g-force data, very scary and surprising we got away with it, but after a few trials of different baffling we managed to get a setup that worked very well. So to answer the initially question in our experience an overfilled standard sump seems to work no problem it's when you start to reduce the oil volume you start to see problems but like Charlie said unless your logging oil pressure your just guessing.

[Bowtie Man]

Thanks for your help, we'll definitely start logging our oil pressure, and likely modify our oilpan with some spring loaded doors to keep the pickup in the oil.

Don't be surprised to be shocked at what you find. We found a pretty consistant &lt;2.5psi under the hard corners before further baffling.
