rtm4676 Posted March 20, 2009 Posted March 20, 2009 I have been told that if you run slicks you should also baffle the sump as the extra cornering force will cause the oil to surge to one side of the sump away from the pickup, leading to oil starvation is this true. We're talking about KH here also (not the ring..) anyone??
JohnSt Posted March 20, 2009 Posted March 20, 2009 (edited) Really depends on how well setup your car is, but realistically, I would certainly be thinking about it Edited March 20, 2009 by JohnSt

~ ~ Cal ~~ Posted March 20, 2009 Posted March 20, 2009 bear in mind that KH is all about a relatively quick sucession of right hand corners. The ring is more punishing on the suspension I'd say. Long straights a mix of varied corners at ring means that I'd be less concerned about oil starvation. Better to be safe than sorry though
braveheart Posted March 21, 2009 Posted March 21, 2009 I am running a cosworth sump with baffel plate as people, has advised it to stop oil surge and your engine deciding not to play anymore, would only suggest to replace it if you intending to do alot of track and alot of twisties are near you it give me piece of mind when on the track.. hope this helps .

I'll not hold you to the penny..
braveheart Posted March 21, 2009 Posted March 21, 2009 what sort of money are they to buy and have fitted? I'll not hold you to the penny.. This is what i put on mines and the prices, dont know if you can get them cheaper. I had trouble with the sump trying to get them to fit around the aftermarket headers but SW motorsport sorted that problem.. and if you want some 1 to do the work then use him.. COSWORTH BIGWING SUMP PAN £393 COSWORTH BAFFLE PLATE £149. Regards Chris
TrackScotland Posted March 22, 2009 Posted March 22, 2009 that cosworth baffle plate doesnt really stop oil movig around.... it prevents it getting sucked up the breathers and into inlet/catch tank. Ideally with the standard sump you want a baffle tray with trap doors or such like. Anyone know of off the shelf kits like that?
TrackScotland Posted March 22, 2009 Posted March 22, 2009 ok, the cosworth one isnt as bad as i thought http://www.zenperformance.co.uk/p/product/en Cosworth Oil Sump Baffle PlateAll Subaru Applications £161.62 +vat Engineered with diverters to control oil returning from the cylinder heads to the oil pan directing it away from the crankshaft. Additionally, one-way valves prevent oil from reentering the upper crankcase chamber thereby limiting blow by and preventing oil starvation during hard driving.
rtm4676 Posted March 22, 2009 Author Posted March 22, 2009 ok, the cosworth one isnt as bad as i thoughthttp://www.zenperformance.co.uk/p/product/en Thats more like it price wise, the chap who paid around £500 must have been feeling flush or is there something special there?
JohnSt Posted March 22, 2009 Posted March 22, 2009 That Baffle plate is more of a windage tray really, whilst a good idea, it'll not prevent surge on it's own. You need a properly baffled sump for that. If I get a minute I'll take a pic of my Lateral Performance Baffle setup. Did a whole season last year without so much as a sniff of oil surge with this on the car. These things aint cheap, but if you consider the relative cost to replacing an engine then it is a sound investment. ---john---
TrackScotland Posted March 22, 2009 Posted March 22, 2009 Any details on that would be perfect John I'm not convinced with the cosworth one....
JohnSt Posted March 22, 2009 Posted March 22, 2009 Andy uses a Cosworth Sump and Baffle plate and is still seeing some surge, however his application is a little different to our cars I think I'm sure they are both a good product. I have an Alloy Big Winged Arc sump in the garage and I wouldn't p1ss in it as I'd probably get wet feet, it's Sh!t. ---john---
TrackScotland Posted March 22, 2009 Posted March 22, 2009 I have a baffled sump in the skyline but have still taken out a set of bearings with starvation. I think it was more high revs, high capacity oil pump, and oil pooling at the back of the head. Now have a restrictor into the head, enlarged drains down, and an external oil drain at the back of the head to the sump. Next step after that would be a big winged sump... but i'm not keen on them as they sit very low. Too low for comfort and kerbs on track!! I need to address the Impreza before sorting out its susp and slicks.

I need to address the Impreza before sorting out its susp and slicks. Obviously the only way to be sure, is to dry sump it, this will be happening on my car sometime soon. With a wet sump you can only do the best you can. Sounds like you've done everything humanly possible for the Skyline Adam. Zen have a dry sump solution in the pipeline, not far away timewise either. Pennine Subaru, I 'believe' are also developing a system
TrackScotland Posted March 22, 2009 Posted March 22, 2009 yup... drysumping is a bit costly for the 'budget' impreza So... apart from a replacement baffled sump, are there drop in baffle trays on the market. With vertical trap doors to pool the oil around the pickup (not horizontal like cosworth)
sma01 Posted March 25, 2009 Posted March 25, 2009 yup... drysumping is a bit costly for the 'budget' impreza So... apart from a replacement baffled sump, are there drop in baffle trays on the market. With vertical trap doors to pool the oil around the pickup (not horizontal like cosworth) had been having a look around for something like this but couldnt find anything, 1 of the boys i know does work on some subaru rally cars and asked about a baffled sump from 1 of them but it was going to be too costly....saying that, spending a lot of cash then i would guess dry sump the way to go. whats the expected cost of kits??
cullenmin Posted March 25, 2009 Posted March 25, 2009 whats the expected cost of kits?? http://www.sumopower.com/product.php/2556/...25_dry_sump_kit Not cheap
JohnSt Posted March 25, 2009 Posted March 25, 2009 Wouldn't buy the Cossie one, it uses normal location pressure pump
RA Dunk Posted March 25, 2009 Posted March 25, 2009 does chy have a website john? cant seem to find anything on the net
JohnSt Posted March 25, 2009 Posted March 25, 2009 Funny you should ask, one of my collegues is building a site for him right now There's a holding page up there for now www.penninesubaru.com or .co.uk for that matter
sma01 Posted March 26, 2009 Posted March 26, 2009 http://www.sumopower.com/product.php/2556/...25_dry_sump_kitNot cheap ouch, that aint cheap at all...
