I do think thats the issue as its fairly repeatable.

Fensport installed it because fankly getting the old sump off is a ball ache. Dave put in 5.4 liters on the dot. I'll top it off and do some more testing.

Cheers

I'd fill with another 0.2 litres and see what happens. Should hopefully be enough to allow oil drainage to keep the level at the pickup.

Did you get a chance to have a look at the pan and baffle setup?

Yeah it looks decent. The top baffle is the one that will actually do anything. The lower one isnt sealed against the sump so it will have less of an effect.

If theres an issue returning oil to the sump under hard acceleration I hope that doesn't translate to cornering! Its fine under braking.

Good job I have a pressure gauge!

Well to say I am pissed off is an understatement. The Moroso baffle is junk. I added 0.4 litres of oil and went for a drive.

I was able to observe a pressure drop under hard acceleration throught the gears AND under heavy braking after a long period of acceleration.

Serves me right for fitting something with no data to back up the claims.

I will be calling Mark and Adrian to let them know my findings.

You're at the high oil mark?

Sure was. I found a load of it inside the radiator too.

I was at the half mark to begin with. The extra 0.4 liters would be over the max. Total oil added since it was fitted yestersay is 5.8 liters.

Where are you reading pressure from? And is there a chance the sensor could be touching something in the engine bay causing the intermittent fault?

I have one waiting to go on, your post makes me think to leave it out...

Hi Lee,

Im measuring pressure at the top gallery next to the ac. Its been fitted for quite a while.

I have considered what could be causing the issue but its so repeatable. 40mph foot down... When I reach about 80-90mph I get a suddend drop then recovery like an oscillation in oil pressure. Obviously I back off and it stabilises. I can make it happen under braking after acceleration too. The guage seems to be working fine and ive done a few track days.

My suspicion is that oil is pooling at the top plate and not returning to the bottom of the sump.

I will talk to Adrian tomorrow. At this point im looking for a refund tbh.

Let me know how you get on.
I have a racersX sump at home aswell but doubt it will clear my manifold.

The stock setup has no need for extra baffling under any reasonable or realistic set of conditions. especially not under street conditions. It is well-designed and sufficiently baffled.

I suspect if you remove that Moroso baffle, your issues will vanish.

I think I might remember hearing a piece of wisdom on this subject a few hundred thousand times... It starts off "if it ain't broke....

I'm still waiting for somebody to throw up numbers on that Reimax pump. I never heard back from Element on how that went... I've been on the road for a while now, and If I ever make it home and finish moving, I might be forced to get the numbers myself. I'll admit though, I'm losing interest in trying to save the stock engine and transmission. Every once in a while I think I hear a nearby dumpster calling for my FA20, and that F*cking Aisin box it's bolted to.

An oil pan baffle won't fix pressure problems for massive power,. It might help people running a stock engine with aero and slicks. Sounds like the baffle he got ain't so hot.

I prefer the car with stock or close to stock power and enjoy the easy limits and control of stock tires.

I was planning on fitting semi slicks to my track day rims, and potentially downforce in the future.

[ajc209]

Fensport are looking into the issue.
