Honestly thought after all this time an ew12 expert would have surfaced. Has anyone removed balancing shafts on one and had the gear wheel cut out then balanced the crank. From experience the vibration with out the  balance shaft is very very noticeable.

And the oil feed to the balance shafts must be blocked to prevent the oil pressure light coming on

I've been talking to AT Power and Pug1Off about making a kit similar to their XU unit for the EW engines.

They're keen, but want to know how much of a market there is.

So, I talked about it, and they made it.

 

Dry Sump kit for all EW engines, including EW10 and EW12.

https://peugeot-tuning-parts.co.uk/~cn49882a/ew10-dry-sump-kit-206-gti-baffled-sump-ew10j4s-peugeot-rc.html

 

They're fitting the test unit up now, planning on availability at the end of 2018.

 

So far from the documents and pictures I've seen it should be pretty good unit. It also involves relocating the oil filter off the front of the block, which should make filter changes a bit easier.

Not cheap of course, but no dry sump seems to be.

 

I've had my car out on track a couple of times recently. I've found with 1G of braking force the stock oil pickup starves, and I get oil pressure spikes down to as low as 27psi.

Now there's a chance this is just an issue because I now have comprehensive data logging, which I didn't before. But even so, it's a worrying level.

I haven't yet taken it to the track here in Melbourne that has killed a few XU engines with it's long fast left hander (Phillip Island). I'm booked for later in November so we'll see how the baffled sump deals with that.

 

In any case, I'm obviously on the pre-order list for one of these dry sumps, because better safe than sorry.

Strangely, we don't have any problems with EW engine loosing pressure in this car. Still stock sump with custom baffle.

That's cool. Are you willing to share more info on the specs of that engine? Revving it out to 8500?

 

The corner that is notorious for killing XU (and other brands) engines at Phillip Island is turn 11 and 12. You can see it here from 3:20. Full throttle, with two high G left turns in a row.

With my baffled sump, I don't seem to be having any cornering issues. My issue is still with braking.

 

I get an oil pressure warning at turn 4 and turn 10 if I brake late and hard. See 2:30 and 3:13 for those corners. It seems like it's uncovering the pickup, maybe even pushing oil up the return hose from the catch can.

It's very brief, and generally with not much throttle, although I am usually trying to blip the throttle to rev-match on the downshift, so still pretty high RPM.
