I hope I’m going to get more of a response to this question here than on Seloc:
I’ve got the car booked in to Essex Autosport in a couple of weeks time for a baffled sump to be fitted. They have two options available, an in-house option and the Moroso option which is �100 more. Does anyone know what the differences are between the two? While I appreciate that Moroso is meant to be a known brand in this area and obviously I’m trying to achieve the best protection possible, I’ve never heard of them and don’t want to pay �100 more for a product which has no material difference to the cheaper option!
I have no extensive modification plans for the car, I just want added peace of mind for the half a dozen trackdays I do each year. I might go for the CN upgrade in a year or two though, don’t know if that would make a difference.
I would ask to look at both. If the design is similar then go with the cheaper one.
Am not and never have been convinced by the accusump as an option, but each to their own.
I also wouldn’t both with catch cans as they don’t work well.
There is a better unit called an oil separator developed for aircraft which is a far better option.
If you want to do it properly, look at the saikou mitchi twin catch can arrangement. They are actually oil separators.
They allow air to be sucked through them (and are plumbed in so that there is a likely vacuum source under all operating conditions) and draw air through them from the breathers.
The oil droplets suspended in the air are heavier and have too much momentum so they are thrown out and collect on the walls of the can then drip down into a collector. This is fed into the sump through a feed below the oil level (so doesn’t affect airflow through the can). The air is capable of exiting the can through a separate pipe that runs up the axis of the can, but the oil droplets can’t travel through the tortuous path to get out.
It works a treat on forced induction cars, so long as you know how to connect them up.
One can gets its vacuum feed from the inlet manifold when off boost with the throttle mostly closed, the other gets its feed upstream of the charger, so that when on boost it is sucking air through the can.
I know you didn’t ask for all that info but since someone mentioned the oil breather option, I thought it best you were armed with info!
Thanks both. That’s the kind of response I was looking for (or too much info in your case Adam!). I suspect once I start adding catch cans it gets properly expensive and I’d rather spend the money on some ohlins, the CN upgrade, a lighter flywheel etc etc first. A baffled pan should be sufficient for what I’m looking for, it’s never going to have 300HP+ while I own it and it’s only going to see the track half a dozen times a year.
I’ll ask to have a look at both versions on the day and make a decision then.
Beware of moroso,s sump plug , unless it has an insert thesedays the alloy thread quickly disintegrates with a few oil changes .
The G pan is another option .
As for catch cans ??
Hmmm what possible benefit could they bring ?
oil catch cans are a good upgrade on our cars, but don’t forget you need them in pairs like saikou or proalloy ones
As for sumps either will be fine I’m sure I plan on having one fitted to go with my Accusump for a belt and braces approach, but only because I am having a new engine fitted or I would not bother.
Search on Lotus Talk, there’s quite a lot of ‘opinion’ there - take it or leave it.
Personally , I’ve gone with the gPan, there’s now a Mk2, can’t see a huge improvement.Nonetheless, seems to work well. Fairly hassle free self-fit.
While I’d love to ensure it couldn’t happen, my primary concern is to reduce the risk of oil starvation and this seems the most cost effective way of doing it. I’m not racing the car so a dry sump seems unnecessary and I don’t want to spend a grand plus on having an accusump fitted (which from reports doesn’t seem foolproof either).
Unless your continuously doing track days at banked circuits like (old) Monza, your just modding for the sake of modding, there are already baffles in a standard sump, and your just pandering to the manufacturer’s of these items, a waste of money IMHO
Adam I have been preaching the benefits of oil seperators / catch cans that have an oil return to the sump on hear for ages, but nobody really wants to listen.
Everyone would prefer to have a couple of cans buried in a tight engine bay, with no way of telling how much is in them and then have a pain in the arse job trying to empty them out.
So to coin one of Franks sayings “what do I know” hahaha
