I swapped the Caterham 6-speed gearbox with a Sadev in winter, and so happy about it. Smooth and lightning fast shifts, no issues anymore to get any gear in - it just works.
Also I'm really happy about the latest cooling modifications - the ambient temperature in the video was around 27°C and you can see 85-88°C water at engine outlet (left instrument) and 95-100°C oil on engine inlet (right instrument) and I didnt really take it easy on the engine. This is about 10°C lower oil temperatures compared to last year, even though a really hot track day will probably push it a little bit further.
My current setup on the k-series is: Radtec cooler with rover oem PRRT, deleted bypass, autobleed banjo in radiator, the large laminova oil-water cooler ECD54-182 in engine outlet before radiator inlet. You just fill the system up and it works, no bleeding necessary. :)
