They will be putting the motor into my car in a couple weeks. I have been told to include a track day sump. Anyone know of any reason for or against. Still not even sure what that is, but I keep reading about it.

Thanks,

Jeff

Essential.

As it's a wet sump, the oil gets forced to one side during high speed cornering. Centrifugal forces and all that.

The trackday sump has baffles to prevent *all* the oil dissappearing from one side of the sump and causing starvation, followed by big expensive blow-ups.

The car will only be warrantied on the track if it has the sump. Under extreme conditions there is a danger of the oil not covering the pick-up and thereby starving the top end of black blood. Unless anyone else can can tell me I'm talking sh1t...

For a car pretty much specifically designed for track day usage, why on earth should you have to pay around £1500 extra (ie. for new sump)in order to use that vehicle on track without invalidating your warranty? This is a pretty poor show in my opinion given the pedigree of vehicle we are talking about here.

I don't recall similar work having to be done on TVR's, Porsches, Elises, Evo's etc.before they are fit for track use.

The track day sump should be standard unless someone can teel me of a disadvantage of having it on in normal road use?

Kinetic,

I suppose it's down to the "lack" of Nobles at track days it seems clear that most users don't track them (no - I don't know why either!) - and so I'm sure that those owners like the fact that they pay £1500 less than having it bunged in for standard.

Whilst we all think that everyone that buys a Noble should track them - it's clear as the ownership expands they aren't all mad driving nutters like us lot!

I presume Noble know this and to meet various market price points.

Funny enough it seems a bit widespread - it's apparently the same with some M3's that can benifit from a baffled sump at extra cost according to the BMW Car Club GB's forums - so I wonder how many other wet sumped cars have problems? Obviously anything dry sumped will be fine.

I think most road cars with wet sumps will potentially suffer from oil starvation on track, I use to have a V8 Esprit that cost me a engine rebuild for exactly that reason and Lotus said not designed for track use ! at least Noble offer the option.

that's a bit of a strange attitude from Lotus - I would have thought given their test bed is a track they would have sorted that out!

Live and learn on here every day.

Good point. A disadvantage of it being an option is that (according to at least one insurer I approached), just choosing to have a track day sump fitted gives you the potential to go on track and thus they want a higher premium for the modification, even if you say you don't want to go on track.

IMHO an advantage of NOT fitting one is that reselling a car that hasn't been on the race track is likely to be easier.

I'm sure it was less than £1500 when I got it (at build time) - £500 rings a bell.

Very true, but you have to rely on owners having a little common sense and NOT going on track without the necessary mod.

They must have been mixing this up with the cost for the original 6-speed box?!

I thought it was £1100 + vat as a retro fit option but I'm not absolutely sure since it was about 12 months ago that I enquired. I'm sure it was £1k plus though!

Kinetic,

If you have the sump retro fitted it means cutting the chassis to change unless you pay to have the engine removed, it's cheaper to have it fitted when car in assembly I think it's about £500 + vat.
Suggest you contact Simon at the factory who will quote you properly.
