CSR Dry Sump

[Trackdayguy]

What a horrid system this is. In principle it's a great idea, in practice it's a disaster and can lead to massive engine failure. As a general rule all engine oil lines that run externally in an engine bay are union fittings. Not on the CSR, push fitting O Rings. If one of those O rings fails out drains the oil and engine removal is the only way to fix it.

The current CSR we have is getting its oil pipes re engineered. Stuart from Premier Power Engines has done a great mod, which removes the bell housing system and places a tank in the engine bay. His system also increases the ground clearance by 40mm by using a special sump. The quality of his work is top of the line. What we plan to do is replace the dreadful O ring design with unions, hopefully no more oil leaks.

This sound exactly like the the early R400D dry sump before the Raceline sump became the norm. This ditched the 'through sump' pipes and used standard -12 fittings and external tank. It is very good and adds quite a lot of additional cooling, if not clearance.

So are Caterham using a Raceline system ?

None of that is new, the CSR system on the race cars was changed to an external tank years ago. The "Raceline" was also introduced a long time ago and can be fitted to all Duratec engines.

Thanks for the mention Terry,

Terry is right that this set up has been installed on a couple of CSRs which we believe has an over engineered oil system and that not only causes ground clearance issues, but it's also not very user friendly when it comes to checking the oil level.

Our installation uses the Raceline dry sump kit as used by Caterham, but we use a different bellhousing so you don't end up with a big step under the car that's venerable over kerbs. This also means you can run the car lower should you wish. As part of this we also offer a smaller diameter flywheel which is a slightly lighter version of our Duratec ultralight flywheel, 2.8 kgs lighter than the Caterham fitted flywheel. This means improved throttle response which not only improves gear shifts but also promotes better handling in corners when on track. The oil tank can either be the standard Caterham triangular oil tank that mounts in front of the engine or an easi clean tank that fits in place of the passenger footwell extension. The oil tanks are anodized black and feature a glass sight tube meaning the oil level can easily be checked.

There are various options available here depending upon what customers have on their cars already.
