GR86 Oil starvation

[Beans]

Yeah it's a bummer that this particular baffle didn't help. Someone on yt saw some improvement with Tomei one but it wasn't very significant improvement [emoji20]

I've been following it too and was disappointed to hear the prototype killerb one hasn't helped. I'm sure they'll keep working at it though. That or Toyota/Subaru address it to restore some confidence in this otherwise awesome platform!

We learn that the problem "starvation" doesn't relate to the oil pan. We don't have any measurements of the standard setup (with oil/water cooler), nobody knows, everybody is confused. My recommendation: Just forget any modification. Keep the system standard (be sure, it's adequate) and use recommended oil. If something fails you'll have Toyota to pay for.

Bye for now Fred

It seems to be that the majority of observed failures and most of the GR86 crashes occur in the USA? Could that be because they can't escape the 'Fast & Furious' mentality regarding Japanese cars or is it because of something else? The GR86, despite what Toyota publicity material would have us believe, is not really a car built for the track; it seems to be more of a focussed road car. My local track (Knockhill) in Fife is only a few miles up the road but knowing how many vehicles have 'come a cropper' on its harsh inclines and diverse cambers I'm never likely to expose the GR86 to such an environment. I don't have deep enough pockets that's for sure!

I did a track experience at Knockhill I thought it was nice, although quite short. My local track at Croft is exactly 4 miles away. I've done a track day there and Oulton Park (courtesy of Toyota) when I had my GT86. Also took it to the 'ring (where it was a lot of fun).

They have 50x the number of cars, and also got them before the UK

The climate is also a lot hotter than here. At least from what I have seen. Most tracks like willow springs, Laguna Seca etc are all in the hot south.

If people are that worried about it though but would like to go on track Blyton Park is a small anticlock wise track so mostly left turns and apart from the first left hander it basically all flat. You also do not get a lot of speed like Donny or Snetterton so is mostly bad on brakes and tyres.

If you are going to track your car then an oil cooler, baffle and high viscosity oil would be wise. Otherwise for normal road use/spirited driving, my only thought about this is that if it is true that right hand bends are the cause of low oil pressure then the UK with all it's roundabouts might cause higher engine wear and possibly failures. If this is the case then perhaps the baffle is a sensible upgrade.

Well I'm one of the earliest cars, am smashing on the mileage and drive it properly so wait till I go pop then buy one

The US chaps tested a baffle from killerb motorsport and saw that drops were still occurring so I don't think this one will work either.
It may be that the solution is to use an accusump setup

Cusco one is completely different design compared to this KillerB joke. It's closer in design to Tomei one which showed to (slightly) improve oil pressure.
Baffle vs no baffle (Tomei)

 

[Mick]

The KillerB setup makes the oil pressure wrose.

Its just a baffle that sits where pickup goes and the stupid pre filter cage.

 

[Cubone]

Somebody has posted a video here of a canyon run with an oil pressure sensor fitted. The pressure doesn't dip massively compared to the track video, so that does give me some confidence that moderately spirited driving on normal roads doesn't cause drastic pressure drops when compared to the track video. It would be good to see similar tests done on completely stock cars, as both videos are on cars with oil coolers.

 

[AdamST205]

Everything is almost pointing to the actual pan not being big enough due to something to do with the design of the engine preventing oil to get back to the sump. A large capacity sump with proper baffles in it should solve the issue.

Does a larger capacity sump generally mean
a lower underground clearance?

 

[MrSkubi]

Not really. Larger sumps are often longer/wider in the first place. Noone wants to sacrifice ground clearance unless there is no other way to get more oil in. Second of all it will be rather hard to find market for sump that makes fitting undertray harder or even impossible.

Most of them are larger width ways and made to fit into the car correctly. The other benefit of having an increased capacity oil pan is keeping the oil cooler as well for longer. My quite limited search seems to be that there is very little available on the aftermarket for the old GT86? I guess this issue wasn't a problem in the 2.0 or more than likely the speeds were a lot slower compared to the new chassis and engine combo of the 2.4.

When my delivery arrives I might even look into getting one made up.

The GT86 definitely had issues with oil starvation and oil temperature issues. If you're tracking it's advised you get a baffle plate and oil cooler, but that's normal for most cars tbh

I had a Mk1 XR2 in '88 and on long right handers the oil light flickered on... I was on a technicians course in the RAF at the time so when we covered engines I brought the car in and dropped the sump... The previous owner had obviously tw*tted it and replaced the pan but not the bent pickup...

New one fitted and it was sweet...

This looks like it might do the trick. Although not sure about clearance issues with the standard manifold and are the 2.0 sumps interchangeable with the 2.4?

Would be a very low cost solution to ragging it on track.

900BRZ’s latest video went up today, looks like he’s going a for a custom baffle setup to reduce sloshing.

 

[Mick]

A 12 minutes video to tell you he's removing the KillerB baffle and fitting another one he can't tell you about, oh also give him money to fund his track days
