R500 with the sequential box
Discussion
The C400 uses a solid clutch.
The sump pan has not changed, and the move to an external tank was nothing to do with crankcase pressures or volume.
I don't know who was complaining of fottwell temeratures, but I'm surprised - the air duct into the pedal box that's been on there for 2 years now is very effective (if less than elegant). Re-siting the oil tank has also helped.

fair enough stuart 
, it was only the information that I was told
So what is the solid clutch ?
so the dry sump scavenge system hasnt changed this season by manufacturer or design ?
the crankcase ventilation I was refering to was the rod exiting the block.

Drivers were complaining of excessive footwell temps .
I showed them my foil/bubble/foil footwell insulation
that keeps my feet loverly and cool.

Looks like that problem may have resurfaced on the R300 racecar though Stuart? Didn't one of the drivers have to retire in the first Eurocup race?

The two R300's in the E/cup race where both not fully complete when they ran, the idea was to shakedown the cars. I for instance new we had not recieved the heat shielding for my car or the ram air kit for the pedal box but still pressed to run it, I pulled the car in from Race 1 for several reasons, amongst them the heat build up but also I was knackered and had bigger fish to fry that weekend
Team FS & DPR, running the 300's that weekend had worked thru the meeting (despite having much more serious entries to hadle)to finish the cars.....this culminated in a stunning final race with both cars finishing 1st & 2nd overall less than a car lenght apart after 40 mins in crap weather.
It's going to be a great Race car...............

re the cooling under the bonnet, I think Mars was trying to show you all what I have done on my new R500.
Heres the picture:
I also did this on my previous R400 and it really decreased tunnel temps inside the car to an acceptable level.

Ahah, you have to "get the link" rather than copy it from the address bar. Haven't used Webshots before. Oops.Heres the picture:

Yes, this heat reflecting stuff is fabulous. If/when I build another Se7en again, I'll plaster the car in it. It seems even stickier than gaffa tape, previously the holder of the "stickiest stuff ever" award.
Looks really neat on the car. I recall on our run down into Italy in 2003 the cockpit temps got close to 65 degrees and we didn't have black-coated panels. Nige turned up to my house one Summer with his mate as passenger. Both had burns on their legs and the gearbox tunnel had warped from the heat. This sticky stuff completely eliminates that problem.
Nige, we are all getting old, so we will forgive your short term memory loss.
I got it from Nimbus Motorsport of the web thing here:

You can get it in various sizes too.

Footwell temperatures are fine in my car, but I regularly get my left leg burnt by the transmission tunnel
Clutch is a weak link in the C400, and is considered a 'service item'. They are known to pack in on a race start. I regularly see a nice trail of smoke from the centre of the cars in front of me when launching.
Arnie, the ram air kit is literally a 10cm(ish) length piece of 5-7cm guage tube mounted at 90 degrees to the right hand side of the pedal box cover. This then protrudes through a hole in the bonnet which is covered by a simple scoop. It is very crude

Interesting that the race CSR, despite a slightly bigger engine, doesn't suffer from the heat soak problems that initially bugged the C400. I guess the slightly larger chassis provides just enogh extra space and ventilation to prevent the heat build-up.
On the gearbox side, I've been running the quaife sequential in my CSR all season and its pretty bullet proof. There seem to be some performance gains and not just from where you'd expect: yes the clutchless upshifts are worth a bit - someone who's opinion I respect reckoned about a second a lap as Spa - but the important bit for me is the confidence it gives from ultra reliable downshifts so I can focus on the braking without worrying that I'm going to shift from 6th to 2nd instead of 4th or otherwise fumble the change. (Note: messing up the downshift at e.g Paddock/Brands, is quick & certain route into the gravel.) Personally I don't try clutchless downshifts as the risk of unsettling the car or locking the rears is too high.
The new R300 looks to be rather good. Known technology, under-stressed engine so should be straightforward to set up and mechanically bullet-proof. The engine size is the only odd bit: not a problem for one make racing in CC's own series but its going to be uncompetitive in club racing where 170bhp from 2 litres won't cut the mustard in conventional capacity based classes.
