Oil surge

[paros]

I must confess to be frightened by the idea of foam for all the reasons stated.
For my S4, and complying with FIA regs etc I use a QED wet baffled sump. No problems although I do overfill by half a pint - still misses the crank.
Last weekend at Greek circuit which is very tight in some parts and fastre open corners elsewhere, the car was on pole in front of 911's, GT40, Fords, lafas etc and as we use slicks it was pulling plenty of 'g' and also outbraking the bigger braked cars. No surge or loss of pressure [ when I dared to look ]. Traditionally I would go for dry sumping but now find myself wondering just how much bhp loss there is with a wet sump as it is so easy and cost effective.
My advice to the original question is a baffled sump, problem solved.

I would like to baffle my sump (another excuse to use my welder!!), has anyone got a picture or drawing I could use?

(PS thanks for the replies, some interesting points!)

Richard - didn't you have a letter published in the Club lotus mag a while ago saying that you'd discovered that the oil-surge resulted from under-filling the sump owing to the the dipstick having recessed into its holder?

Sorry - duplicated posting.

I have posted some photos of the baffling arrangements I use in the pictures section of the Yahoo Elanmods groups. If you want, send me a PM and I can send a more complete set of photos.

One way keep the heat to a minimum would be to fun alum hardlines with insulators ( aeroquip firesleve ) inside the sills with the sill pannels on and install the tank in the trunk - I don't like the long line runs vs the short ones I have ( have often wondered if leaving the tubes bare and venting the sill would cool the oil ala porsches loop cooler )

Interesting. This thought had crossed my mind though in slightly a different form. I'm planning on running a side intrusion bar tube from the front of the footwell, through the side sill under the corner of the roll loop. I was thinking I could either run the oil tube through that or if I can work out how to seal the side tube, use the tube itself. Time to go do some measuring and thinking...

thanks,
