Baffled sumps?
Discussion
I have a Fiesta ST, have done one track day in it at Anglesey and came away wanting more but decided that the brakes werent up to the job, so have ordered an EBC 330 mm and going to order some AR1s rather than killing the PS5s that are on it.
The other mod before the next TD (not booked yet) was a baffled sump so will fit that when I do the oil change, I did pick up on a comment on another forum that said can do more harm than good in a Daily Driven car, it doesnt do many miles and eventually will become mainly a track day car but can anyone expand on that or is it just someone spouting nonsense ? Said unless regularly pulling 1.2 G in the corners its not needed and will do more harm than good ?
But guess with a set of AR1s on, its probably best to have it fitted ?

The baffles in the sump are designed to keep oil around the pick up tube under high-g scenarios. Whether you're tearing arsing around a track flat out or pottering to the shops, oil near the pick up is a good thing. I'm struggling to see any situation where a baffled sump would be a deficit. Nonsense as far as I'm aware.

This, having a properly baffled sump is not a bad thing under any circumstance as far as i'm aware. I've seen instances previously where poorly-installed baffles have come loose from the sump, thereby cracking some of the weld used to secure it, and the weld fragments have then been sucked up through the oil pick up - this small instance aside I would get one for track use.

I would be asking for an explanation of this as all a baffled sump does is help to keep oil around the pick-up tube so it will make no difference to a daily.I have one on my TVR too.
The old Rover V8 engine doesn't like oil starvation, and on track days and sticky tyres there are a lot of higher than normal G forces in every direction.
Road conditions wouldn't cause a problem, the baffles are there to stop all the oil ending up in one part of the sump away from the pickup in extreme conditions.

There's more to this than just pressure and dry sump is the definitive solution. If oil is sloshing about in the sump there's a risk of the crank dipping into it and whipping air bubbles into the oil - which is a bad thing, because the oil pump will pump aerated oil into places that need 100% liquid oil.
