These pressure drops is what stopped me from pulling the trigger on one of these. This really make a big difference as seen in the data. Even more results could come in the future with different oil pan/pickup changes. I'm starting to feel good about buying one now. Thanks for all of this!
From everything I have seen this is working wonders. If you're still feeling iffy check out the use with drysump. Apparently it comes pretty close to negating the pressure drops. Some people are saying it's overkill. Edit: I have a gr86 but this is not from personal experience just from everything I've seen and read
@@actseight9358 Dry Sump is needed if you're in the WRC or GT300 etc. Otherwise it's waste of money. They cost a fortune and are only for legit racing applications. No one in the comments needs one. Not even the GR86 Cup uses them.
What's concerning is it shows starvation on right handers even below 1 G. This could be seen in autox too where transitional forces I've seen creep over 1 G but it's more instantaneous than constant.. How did subaru botch the oil return in a motor meant for intro high performance yet Mazda and honda design their engines with + 1.3g capability
Well, I don't know wehere do you live but here in Europe the Subaru engines are legendary due to their ability to seize themselves up in no time. Especially the 2,5 litres in STI's and 2 litre diesels. So it is no surprise for me that they botched up another engine as well.
I am actually surprised this issue hasnt been resolved. People are not thinking physics. If it was just oil pickup, problem would have been solved long ago. The issue in my curiosity in the situation points me to the timing cover. We must think physics. Pump still puts out same. It is a linear pressure drop, so not sucking air. The problem I see? The oil pumps to filter housing on extreme left side. On a higher G right turn? The length of the feed to crank and onto right side of engine has to fight that hydraulic head which coincides with where oil pressure sensors are. Path of least resistance. Oil primarily will follow the left channel return. Want to fix the issue? Need either flow restrictors so fluid needs to keep to the right bank which will still have a head pressure loss or a new timing cover to centralize the oil filter. Third option is if the cover is designed like a manifold so all oil flow out of filter housing goes to a central branch, and then off to left and right ensuring bottom end always has the priority path vs left head priority. Rest is stopgaps to compensate, but doesnt solve the issue.
A big part of it is the engine layout. In a Boxster oil is going side to side, instead of just up and down like a Inline 4. Porsche solved this problem by adding scavenging pumps and pickups that take the excess oil back into the system. That being said Honda and Mazda have their own issues. ND1 trans blows up on the track. Honda still hasn't fixed the overheating issue with the 2.0T, that can cause it to melt internals when pushing hard on the track. GR Corolla has overheating issues too. And you can probably actually blame Toyota, because it was the guy that developed the MKV Supra that was in charge of both Gens of the 86/BRZ. Kind of funny too how when GR races the 86, they put the turbo 3 cyl from the GR Yaris in it. Lmo They don't even want to use the Boxster engine they insisted it had to have.
Bare in mind just because you register a dip in pressure still, it is still helping as the accumulator is continuing oil flow through the engine and pressure gradually falls off as the piston pushes oil volume out. So you're maintaining oil volume as well as pressure.
Thank you. I wonder how Toyota is solving this issue right now in their own GR86s while racing. I also wonder if Toyota and Subaru are working on a solution for the facelift.
@@jackp8022 900brz is gonna be testing multiple different overfills since he got better results with more oil, but the car also had a baffle, so he's gonna do that testing without the baffle in.
Thank you so much for this! Very helpful and detailed. IMO, since the car is new/ stock and under warranty, continue to drive as is and have fun. We as consumers didn't design the engine, and the car is marketed for performance driving, whether you take left or right turns. The only thing that may cause warranty denial, is blaming it on money shifting or low oil, in which we can 100% control.1) Make sure fluids are full, 2) try not to money shift
@@FujiboHeavy The problem with that is you may scuff a bearing, it degrades just slow enough that after your warranty is up it develops a knock and then fails. I understand your logic, but as a research and development engineer for internal combustion engines that seems like a bad idea. You could use their strategy and prevent oil starving thus maintain bearing health and avoid possible large costs of repair in the future.
@@turbobros_online1561 agreed. I would personally use this method for peace of mind if it was dedicated track car. But I would say my view is more for the daily driver but maybe 1-2 track days a year. I see what you mean long term. Who knows, I may end up doing it once I understand the system more. Especially if its something you can turn on/off
I'm glad someone is finally doing a review on this product. I am trying to run this to help with the oil pressure issue. However alot of builders seems to think that this is an added risk. I had one builder explain failure and pushing all the reserve oil into the block...I just need to find a way to set it up, and maintenance for the valve and system....can't wait for the next vid good or bad
This is really good data, and an incredibly POV hotlap. Sorry if you get asked this all the time, but what exhaust setup are you running? The sound gives me goosebumps.
We have a Ace cs400 header and no mufflers. Mid pipe is stock. Intake side we have the charcoal filter removed with a bmc filter and Ansix auto snorkle.
my main concern is adding an accusump MAY solve the oil pressure, but you'll loose the engine warranty. If I don't add it, I'll at least have warranty. It's a loose loose situation.
@@andrikbalderas5628That goes back to the initial warranty claims about the car that blew up because they saw it oversteering. The car comes with a 1yr NASA membership. Subaru was handling warranty issues easily, Toyota was more of a pain but usually honored it.
After clicking the link for the install kit this text is somewhat concerning: "The advantage of the Accusump is the larger capacity over the Moroso, 2 quarts vs 1.5 quarts. The disadvantage of the Accusump is the relief valve on the oil side which can spray oil all over the engine bay and become a fire hazard as well as completely emptying your sump. "
I never had problems measuring the oil on the dip stick on any of my other cars, but for some reason this car’s dip stick measuring is inconsistent. It only shows on one side and I always get different levels from cold to hot and even worse with a cooler. After my 1k mile break in oil change I’ve always put 6 quarts cause of that and have been ever since (I added extra on the cooler install of course) 6 track events back to back hitting high G’s with 200tw.
Great content! If possible can you add an additional comparison with a 1L overfill ? Curious to know how how close this gets you to the Accusump pressures.
ive noticed that most japanese GR86/BRZ tuners are using a very simple PCV catch can setup, the usual very generic ones at that. That should also be effective in allowing the overfill without oil getting into the intake. Although, its likely you will have a full catch can after a track day.
We'd love to see more information. Do you have any logs or any information about the baffle that came with your car? Our car is a 2023 model year and it didn't have anything different compared to the previous model year.
I have watched so many videos on accusumps. I think the hardest information to find is how do I use it in my day to day. Do I have to manually open the valve once I start my car? Do I have to close the valve before turning off my car? If running an electric valve what signal would I want to trigger the valve opening or closing? I have looked everywhere for this info and can never get good answers. Thanks
@@AnsixAuto I seen in the video that you were going to do a video on questions people had so I had to ask. I will keep my fingers crossed for the next video. Maybe it’s a dark art or magical secrets but no one ever addresses my previous question. Every video is installation and driving the car. No one shows the in between. Thanks 🤙🏽
The oil pressure isn't an issue with the WRX and other FA24 engines right ? I know you're still working on a proper answer to the why question but I find it interesting that it's only seen in the track oriented car.
@@AnsixAuto Oh, absolutely, I meant it with sarcasm because it's the one car that actually had to endure high Gs. And hopefully we find out if the WRX doesn't have the same issue, thanks for all the hard work!
Love the data overlay on the video! What are you using to record the telemetry and display things like the oil pressure, steering angle, and brake accumulator?
We use the app RaceChrono logging with a ODBLink MX+ and the Ansix Auto oil pressure sensor kit. All the data on the canbus can be logged and displayed.
When the valve is closed on the Accusump does it just hold oil like a reservoir, or is drained into the main oil circulation when not in use? Because wouldn’t there be some issue when opening the value to have the now cold oil just immediately mix with 200 degree oil? (I have no idea how this stuff works but I am interested in the solution for my GR86)
Good video, but unless you track this street car, does it really matter? And if you track, you end up having to put on other things that the OEM doesn’t include. Do people normally drive like this going to work or the store. No. Just add a 2/3 quart extra oil before you track and remove after you are done.
It would be nice to see a video of a stock car with one of these installed as most baffles on the market look pretty pointless compared to proper baffled sumps on other cars.@@AnsixAuto
Is it possible to still daily the gr/brz with the valve closed or do you still need to open/close procedure? I probably will only see 2-3 track sessions a year.
This was really clean editing. Does anyone know if this voids your warranty on your engine? I imagine it does but I'm just curious if anyone knows for sure.
I don't track my 2022 86, but I do enjoy canyon carving....would that be enough to warrant getting the Accusump ?! I'm just trying to prevent the RTV issue from happening or contribution too it since I know Toyota won't cover it under warranty even though technically they should.....
@@AnsixAuto problem is getting a shop to do it without it voiding the warranty, dealership won't even touch because of a handful of reasons they gave me. They said they've never even heard of the RTV issue, full of crap right?! Couldn't even get them to check my diff plug cuz it was leaking, they said only if I spent 6G for a complete rebuild kit...the car had 6k "soft" miles at the time! I looked at it....loose so I bought a brand new one and diff fluid. but now it's in the system as damaged and void warranty.
I do have a question, I'm not sure if I missed it but what weight of Oil was being run with the vehicle? A lot of people switch to higher weight oils during track use.
@@AnsixAuto got it, and now for my stupid question. Lets say after track day Im done with the 5w40 then drain it to put 0w-20 back in for street use. Can leave the accusump with 5w-40 in it? 😶
@@CrescentBRZ Yah you can leave the 5W40 in there. If wherever you live isn't that cold, you likely don't need to switch back to 0w20 unless you want the minor benefit of better fuel economy.
With the manual valve do you have any oil overfilling problems when entering the pits? I know these cars run with very low oil pressure when idling hot. Im new to accusumps and I want to know how you fill up the canister with oil as well, do you just add an extra 2qt when doing a regular oil change?
We're going to make a video shortly explaining how to setup the Accusump. The idea is, you fill the accusump and close the valve, then you correct the engine oil level. There isn't really an issue with it overfilling, it's just one extra quart in the sump at idle.
It’s interesting that the GR86 cup, TCA BRZ and GR86/BRZ Race in Japan are using stock motors and haven’t seen any blew. Curious as to what they are doing?
Yes and they have been proven (check Element Tuning). First gens oiling problems usually occur when running greater power levels with forced induction, which require extra oil pressure at the rod bearings to maintain the oil wedge. I've killed 2 engines because of this
Band aid IMO. If the pressure has dropped, it's already too late and I suspect this will only work for so long. Either the engine needs to be fixed, or dry sump is the way to go. I really wish dry sump kits were cheaper :(
This issue has been around since the 90's on all of the Subaru performance engines. Its really terrible subaru never did anything to try fix it. The only reliable tracked subarus ive seen all have accusumps or dry sumps. Baffled sumps imo make no difference to these motors.
@@AnsixAuto i think porsche managed to control oil surge by having small scavenge pumps in the heads! But I know some porsche models also suffer from oil surge.
@@AnsixAuto I see, so it is automatically controlling pressure even with just a manual valve? I'm new to these kinds of systems so thanks for letting me know. I'm definitely going to pick one up as soon as I can. I would like a video on a more in depth explanation and setting up if you ever get around to it.
@@burakoshimazakiWe're going to make a video explaining it in the near future. The Accusump behaves like a big balloon in the oiling system. When the pressure it high, it fills up and when the pressure is low, it deflates and supplies the engine with oil.
@@burakoshimazaki The amount of oil being stored is limited. The oil level of the engine is set with the accumulator filled. The accusump should not change whether or not the picup experiences cavitation.
Here's a thought...just let the engine pop and upgrade to a Honda K series engine for more power and endless reliability plus you get the bonus of a great sounding engine. Thank me later.
The pressure drops, and Toyota being c*nty about shelling out for warranty coverage (and neither automaker seeming to be developing a solution on the production side) all pushed me away from this car. And I had a 2015 BRZ from new for years. So I snagged a used 370Z and haven’t looked back.
the fact that you (the consumer) has to fix a design flaw made by the car manufacturer, just confirms that this car is badly made. I am glad I bought a 2020 gt86 with still 2 yrs warranty left instead if this shit box
Well, may be as it is true that it takes energy to refill. My thought on a positive displacement pump what would happen is that oil pressure will drop back to the remaining pressure in the accumulator until refilled, that is up to the tertiary valve. The key a proper discharge and refill rate.
Ty for the input. Subaru should step up and make it stock equipment. They, SUBARU, aren't starving - (they leave that to their vehicle engines) Cars are as much as houses, used to be, not so long ago. Making excuses for not doing the right thing on a RACE INPSIRED INTRODUCTION car, is NOT the way to treat LOYAL customers. As previously stated, It Shouldn't even be an issue. PERIOD.
Just going to say what so many are thinking. This shouldn't even be an issue. Subaru owes everyone a fix. Simple as that. Design flaws should be remedied by the manufacturer, not the consumer. Very disappointed this even a thing.
The only way to fix oil pressure drops is to stop using the boxer engine completely and Subaru probably isn't going to do that. The only mitigation is with special tools like a dry sump, which is what Porsche has done ON VERY SPECIFIC MODELS, specifically the ones meant to be raced. That doesn't make sense for 99.99% of Subaru owners who never see a track, and not even 99% of BRZ owners who never hit the sustained Gs required with the stock tires.

@aesir0784 I don't think people want to pay an extra $500 on every Subaru for a problem that doesn't exist except for literally 5 people who raced their BRZs too hard. The same can be said for Porsche, they aren't starving yet they don't put a dry sump except for special models.

It would not be necessary. We'd recommend cleaning the RTV from the pickup though.
Will pressure drop affect me on curvey roads if i am going fast
On the street you'll likely be fine. I wouldn't be too concerned.
Excellent results! By the way, what is your precharge pressure for the oil accumulator?
Around 8 PSI.
The subaruness of these engines is why I will engine swap if mine dies.
Is this a problem only on a track or the street as well? I'm can only assume that there is no data for regular street driving.
Do you run sump baffles?
Yes we have baffles, watch our previous video to see all the mods on our car.
Is it possible to still daily the gr/brz with the valve closed or do you still need to open/close procedure? I probably will only see 2-3 track sessions a year.
Absolutely, that's what we do. We only have it open on track.
This was really clean editing.
Does anyone know if this voids your warranty on your engine? I imagine it does but I'm just curious if anyone knows for sure.
Are you using RaceChrono and logging OBD2 for your data? Anything special to get that to work? Great video!
why isnt there a class action lawsuit?
May I know what the accusump size you installed?
We have a 2 quart accusump installed.
Are WRXs affected by this, since they also have FA24s?
Where do you plumb the Accusump into? Going to get a Moroso Accumulator for my GR86. Thanks!
It goes into a galley port below the intake elbow.
I don't track my 2022 86, but I do enjoy canyon carving....would that be enough to warrant getting the Accusump ?! I'm just trying to prevent the RTV issue from happening or contribution too it since I know Toyota won't cover it under warranty even though technically they should.....
I wouldn't be too concerned if you're not tracking. I would consider cleaning out the RTV though.
@@AnsixAuto problem is getting a shop to do it without it voiding the warranty, dealership won't even touch because of a handful of reasons they gave me. They said they've never even heard of the RTV issue, full of crap right?! Couldn't even get them to check my diff plug cuz it was leaking, they said only if I spent 6G for a complete rebuild kit...the car had 6k "soft" miles at the time! I looked at it....loose so I bought a brand new one and diff fluid. but now it's in the system as damaged and void warranty.
@@AnsixAuto I'd like too, but apparently no shops wanna touch it at this point and I don't have the resources to do it myself
I do have a question, I'm not sure if I missed it but what weight of Oil was being run with the vehicle?
A lot of people switch to higher weight oils during track use.
We're running 5w40
@@AnsixAuto got it, and now for my stupid question. Lets say after track day Im done with the 5w40 then drain it to put 0w-20 back in for street use. Can leave the accusump with 5w-40 in it? 😶
@@CrescentBRZ Yah you can leave the 5W40 in there. If wherever you live isn't that cold, you likely don't need to switch back to 0w20 unless you want the minor benefit of better fuel economy.
Sorry for the unrelated question but who makes that epic swan neck wing?
It’s a rep Adro wing with endplates we designed in house.
does this void the warranty?
You'll have to ask the dealer!
Will the Accusump work on the first generation?
Yes, it works for any car.
@@AnsixAuto can you ship to South Africa?
@@daniyaalmaneveld3779 Yes we can. Maybe not the Accusump itself though.
With the manual valve do you have any oil overfilling problems when entering the pits? I know these cars run with very low oil pressure when idling hot.
Im new to accusumps and I want to know how you fill up the canister with oil as well, do you just add an extra 2qt when doing a regular oil change?
We're going to make a video shortly explaining how to setup the Accusump. The idea is, you fill the accusump and close the valve, then you correct the engine oil level. There isn't really an issue with it overfilling, it's just one extra quart in the sump at idle.
It’s interesting that the GR86 cup, TCA BRZ and GR86/BRZ Race in Japan are using stock motors and haven’t seen any blew. Curious as to what they are doing?
That's not true. Motors have blown in GR86 Cup and the GR86 and BRZ race in Japan.
If I get this, do you still recommend using a baffle plate and removing excess RTV? Thanks!
I already bought the tomei baffle but didn't install and i dont know if its compatible with the accusump
@donut media could've certainly benefited from this data a handful of months ago - granted, not on an 86, but boxer nonetheless
We'd be more than happy to help them out!
Will Accusump also work with 1st gen FRS/86/BRZ (FA20)?
1st gen doesn't have oil pressure drops on right hand turns.
@@ruturaj47 ah ic well that is good to hear
Yes it would work. The pressure drops aren’t as bad in the first gen but they still exist. Check out @900brz video on the topic.
Yes and they have been proven (check Element Tuning).
First gens oiling problems usually occur when running greater power levels with forced induction, which require extra oil pressure at the rod bearings to maintain the oil wedge. I've killed 2 engines because of this
Band aid IMO. If the pressure has dropped, it's already too late and I suspect this will only work for so long. Either the engine needs to be fixed, or dry sump is the way to go. I really wish dry sump kits were cheaper :(
This issue has been around since the 90's on all of the Subaru performance engines. Its really terrible subaru never did anything to try fix it. The only reliable tracked subarus ive seen all have accusumps or dry sumps. Baffled sumps imo make no difference to these motors.
It's just an inherent problem with the boxer layout unfortunately.
@@AnsixAuto i think porsche managed to control oil surge by having small scavenge pumps in the heads! But I know some porsche models also suffer from oil surge.
At what pressure does your accusump trigger? I'm unsure what pressure control valve to get.
Our setup uses the manual valve so there isn't a trigger pressure. The Accusump will constantly try to stabilize the pressure in the engine.
@@AnsixAuto I see, so it is automatically controlling pressure even with just a manual valve? I'm new to these kinds of systems so thanks for letting me know. I'm definitely going to pick one up as soon as I can. I would like a video on a more in depth explanation and setting up if you ever get around to it.
@@burakoshimazakiWe're going to make a video explaining it in the near future. The Accusump behaves like a big balloon in the oiling system. When the pressure it high, it fills up and when the pressure is low, it deflates and supplies the engine with oil.
@@AnsixAuto thank you for the reply. Is there ever any concern of too much oil being stored and the pickup experiencing cavitation?
@@burakoshimazaki The amount of oil being stored is limited. The oil level of the engine is set with the accumulator filled. The accusump should not change whether or not the picup experiences cavitation.
For all of you saying you will now "consider" buying one lmao good luck trying to find one that isnt marked up.
Yah.. the demand is still high.
Another group did this already and it was still a fail
Which group?
@@LiquidTurbo czcams.com/video/LEin1Z--koA/video.htmlsi=EFCEwFt1tjM5utNH.
The channel is 900BRZ
Here's a thought...just let the engine pop and upgrade to a Honda K series engine for more power and endless reliability plus you get the bonus of a great sounding engine. Thank me later.
Decent plan. We might choose a different motor just to be different.
That thumbnail.
Too ridiculous?
@@AnsixAuto Bit.
The pressure drops, and Toyota being c*nty about shelling out for warranty coverage (and neither automaker seeming to be developing a solution on the production side) all pushed me away from this car. And I had a 2015 BRZ from new for years.
So I snagged a used 370Z and haven’t looked back.
the fact that you (the consumer) has to fix a design flaw made by the car manufacturer, just confirms that this car is badly made.
I am glad I bought a 2020 gt86 with still 2 yrs warranty left instead if this shit box
The accumulator will lower the engine power because it will need to fill the tank right after usage
That's untrue.
Well, may be as it is true that it takes energy to refill. My thought on a positive displacement pump what would happen is that oil pressure will drop back to the remaining pressure in the accumulator until refilled, that is up to the tertiary valve. The key a proper discharge and refill rate.
Now if you could just fix Toyota using other company's engines.
Ty for the input. Subaru should step up and make it stock equipment.
They, SUBARU, aren't starving - (they leave that to their vehicle engines)
Cars are as much as houses, used to be, not so long ago.
Making excuses for not doing the right thing on a RACE INPSIRED INTRODUCTION car, is NOT the way to treat LOYAL customers.
As previously stated, It Shouldn't even be an issue.
PERIOD.
Just going to say what so many are thinking.
This shouldn't even be an issue.
Subaru owes everyone a fix.
Simple as that. Design flaws should be remedied by the manufacturer, not the consumer.
Very disappointed this even a thing.
The only way to fix oil pressure drops is to stop using the boxer engine completely and Subaru probably isn't going to do that. The only mitigation is with special tools like a dry sump, which is what Porsche has done ON VERY SPECIFIC MODELS, specifically the ones meant to be raced. That doesn't make sense for 99.99% of Subaru owners who never see a track, and not even 99% of BRZ owners who never hit the sustained Gs required with the stock tires.

@aesir0784 I don't think people want to pay an extra $500 on every Subaru for a problem that doesn't exist except for literally 5 people who raced their BRZs too hard. The same can be said for Porsche, they aren't starving yet they don't put a dry sump except for special models.
Not even a like in supoort of truth. Too many FANBOI'S I see... 🤣
@aesir0784 that's cuz you're telling people they need to spend $500 on something that's useless to them
