So if I'm reading this right, you should not go on the track without one?

Surely people have?

I don't have a baffled sump, but at Donington have had a few quite dramatic puffs of oil smoke exiting Macleans when going hard. Having said that, the car uses very little oil even on track days, and I have not thought seriously about fitting a baffled sump, at least not before now

I can definetly see the logic in it though.

I'm with Dembo on this one.

As long as the oil is topped up for the day, I can see any issues.

I believe PJLs engine had well over 120k miles on it when it expired.

The trick is to check you oil AFTER the car has been warmed up and just after you turn the ignition off.

This way you will still have the reserve capacity of the oil filter and a nice full sump to prevent starvation.

In other words take some oil to the track day with you

Thing is though Ron, Dembo has a baffled sump fitted according to his sig.

Dembo, You obviously fitted the baffled sump for a reason and I know you do a fair few trackdays; Precautionary?

OldDogmeat,

Most baffled sumps are a stock sump with some pits of metal welded in to prevent surge. These baffles, if badly installed can come loose, block the oil pickup and therefore cause the thing they're supposed to avoid.

I'm not saying don't baffle, but make sure it's a quality, well designed baffle.

And the cause for PJL's failure was probably not a lack of baffle. It probably was probably running the car at red line in 6th for 10 minutes the night before the track day going across wales.

Chilled,

So basically I imagine a Mugen or Spoon sump would be good then?

For the sake of a few hundred quid it'd be good for peace of mind; Not saying I'm quick enough necessarily to ever need it although I suppose you never know as I imagine wild high speed spins can surge the oil and cause momentary starvation

TBH, you should ALWAYS have a litre of oil with you in the car.

And if your car gets through a litre of oil at a track day, you can forget your baffled sump, you are needing a new engine!

As for why Dembo fitted his baffled sump, you'll have to ask him.

However, we all know Chilled will push the car when on track and was running some sticky rubber.

He speaks from experience and experience is good

I believe Dembo's sum failed so he needed to replace it, he replaced it with the spoon baffled sum as it was cheaper than an OEM sump from Honda, but I am sure he will confirm this. As Chilled has correctly mentioned both the spoon and mugen sumps are modified OEM pans, I would suggest that if you do regular track days for peace of mind you should fit it, oil surge is not related to how many miles are on an engine to my limit knowleage. I know many Japanese modifiers stipulate that this is a necessary modification for regular track use on the S, I am not sure what the Americans view on this subject and I don't track my car.
