the first nobles ran the standard ford ST200/ST220 sump... but there were failures especially on track and the factory came out with an upgrade called
the 'Track day sump' lol
Most nobles now run the TDS, as did I, but when i fitted the motel ECU it because clear to me and another friend (who had the same ecu) that there was
an issue in a specific type of long sweeping corner where oil pressure dropped a little under throttle so my friend developed a bolt in trap door
arrangement that solved the issue completely.
The noble TDS holds just under 10 litres of oil and is just a modified ST220 ford sump with extra sheet metal welded to make it big wing... the new
trap doors are litteraly 4 hinged rectangles around the pickup (which is extended around 1inch longer) to reach the bottom of the larger sump.

Ahh OK, I have seen the tds, strange looking affair, 10 litres is a hell of an additional amount, I will try and modify my existing sump to suit my
proposed application, rallying, no different from track day really, new tig for Xmas I think !!, the noble forums are a mine of information.

complete heads along with new chains new forged rods, new pistons and rings etc etc along with a second hand block and crank (complete engine
basically mostly new) for just over £1k.
Bloody hell I wish I'd seen that lot for sale before rebuilding mine

I went to a dry sump set up on mine after issues with getting sumps to clear my crossmember and also concerns about oil surge etc. Mines also in a
rally car

On mine, i used the standard size st220 sump and made some gated baffles around pick up to stop surge (my engine is longitudinal unlike the Noble
though so probably a bit less likely to have an issue).
As for oil jets, i used bmw valved jets which don't open below around 25 - 30psi and they're drilled/fitted at an angle. I didn't
like the idea of a simple hole/oil bleed like the Noble used. I've seen people use mig welding tips as jets, but it's still just an oil
pressure leak at idle.

Ian,
Any chance of a picture of your gated sections

I didn't take any pictures sorry, but basically it was a box with hinged flaps around the pickup, welded underneath the tin splash plate screwed
into the sump.

Which is exactly what the noble one is like

I have found a firm called g15 engineering, they make baffled gated sumps for cossies etc, I have been in touch with them but they won't sell
me the lower gated box separately, so I will buy an rs 2000 one and modify it to fit, they look good quality so might be of interest to someone else.
