my brake light also flickers under hard cornering, only due to the fact i took out too much fluid (still at max level) when the pads where changed.

Jamie: are you getting one of these?

That's for a K series mate. Also, what Geary doesn't say is that it won't actually help G-force associated oil surge - As i read it, it's a baffle plate that stops the oil getting up to where the crank can churn it into a foam...

Pretty sure it was oil - he was checking the oil level in the pits when he told me.....

This looks like it would do the job nicely, but not sure how much it would be by the time it was shipped from the states.

Still not convined it is really necessary though - not heard of anyone in the UK suffering Yota engine failure that was definitely down to oil starvation.

ANY engine can suffer from it. try doing the banking at rockingham flat out without a baffled sump, then you'll see.

I believe rockingham driver training school bust 3 or 4 elises (k's) before investing in baffled sumps for them

Interesting you quote that, as I've read that Silverstone's 111R's all went back to have Accusumps fitted after they blew up 'several'....

I think it's a problem, just gut feeling, and get the impression that perhaps Lotus are doing their classic 'bury their heads' routine.....

Just IMO, you understand and it's not based on 100% unequivocal proof...

If you want to be sure then a dry sump configuration is the way to go.

i dont think the elise needs a dry sump TBH, nothing like enough G force under normal track conditions to require that. It just adds weight and alot of expense.

The only time its required is on high speed left hand bends that go on for almost 10 seconds. The only ones i can think of are the bankings at rockingham and Pouhon at Spa. A properly designed baffled sump will be ok for that i would think

Yup - agree. In a Caterfield they are useful, because the engine is 90deg out of line with the way it's designed to run. Other worry with the K dry sump I've seen on Caterfields is that it's belt driven (and TBH, looks vulnerable) Throw the belt and the engine would last about 20 seconds before seizing.....

I don't see how you'd overpower a good baffled sump unless you were on a constant banked oval for minutes at a time. Even if you ran the oval at Rockingham, you wouldn't be in a turn for long enough.....

Well, wouldn't be the first time Lotus have done the Ostrich routine, and I hadn't heard of the Silverstone problems before, but on all the web forums (SE, Nyloc, Seloc, Lotus BBS) I don't think I have heard of anyone else blowing up their engine due to oil problems, and given how many 111Rs and Exiges must get tracked every weekend it can't be a common problem. An Accusump or baffled sump must still be the best option just to be sure I guess.

Yup, it was the oil light, just on the 2nd gear chicane approaching the mountain. Also had it once at the chicane at KH and the chicane after the long straight at East Fortune (using 3rd gear made it go away).
No problems for a while, nothing at the ring or Spa.

Cheers,
