foam for fuel cells is old old tech by now.
but no, that won't help with oil lol.

so, Maroooohaaaa sell a baffle, similar to skidnation  (what came first?)anyway, again too expensive (probably have to pay extra for a sticker?) for my tastes & I've no need for jdm scene-points  also, the plate in the sump I've got has a piece already welded in, at the rear sorta 4-8'o-clock (if cambelt @ midnight & flywheel @ 6...) unsure if this is standard? it was an an early ~1989 engine if this means anything Rich. |

I assume you just want to keep the oil around the pickup during heavy braking/cornering? Just weld in some plates with holes in, you don’t need anything special, well within your capabilities Rich 😜

Dumb question...
But if plates are welded in to slow the movement of the oil across the sump and away from the pick-up (with/without holes), won't those plates also slow the movement *back* to the pick-up if there's a reeeeeally long corner that means too much oil escapes from the pick-up location?

Yeah, but in that case nothing short of a dry sump will save the bearings anyway. And that corner would probably need to be 1.5g sustained in a circle  |

And that corner would probably need to be 1.5g sustained in a circle now then, I'm actively looking for a 'cheap' external oilpump, preferably 2 stage (1 scavange & 1 pressure) but they can command high prices even needing serious rebuilds making the sump & plumbing is easy, deciding where to put the oiltank would be another thing  Rich. |

Fuel injection pumps used to fitted inside small “sumps” in petrol tanks to prevent the pump running dry, a similar arrangement around the oil pickup strainer, with holes, should de the same.

Rich - Never knowingly choosing the simple route... lol it's been on my 'list' since deciding to go foreward with the engine mods, sorta nice to have & answers all questions  also. theres more to drysump than just surge-protection, running the crancase in a slight vacuum lessens oil leaks & also helps with 'breathing' / pressurising. theres also less oil 'flying' around inside the crankcase & around the crank / rods sl less frictional losses Fuel injection pumps used to fitted inside small “sumps” in petrol tanks to prevent the pump running dry, a similar arrangement around the oil pickup strainer, with holes, should de the same. sorta the idea of baffling the sump..... Rich. |

So just do it, unless you need more ground clearance, in which case a dry sump is your answer.

If I managed to cut a bunch of baffles, like the ones that sit horizontally ( link), who would be interested in one? They would work out cheaper than skidnation ones. Mark interest below and I'll have a chat with a CNC cutting company. |

Genuine question - is there actually any need for a baffled sump on a MK1/2, I've not heard of any having oil pressure issues on track? Not sure if the Ma5da cup cars run one?

Most people don't log oil-pressures. Many who do tend to see oil pressure dips under braking. It probably depends...and a simple flat plate fixes it completely. |
