Dear all, another successful day at Croft Circuit track day yesterday. Driving there - setting off at 05:00 on M62 over Pennines - raining all the way there and about 10-15'C outside temp - the water temp sat at 75'C. Average around 70mph. Giving it a good go on the track - when doing silly speeds the water temp went down to about 65'C, but on the out lap comes up immediately to about 80'C. When stationary in the garage the heat from the compressor and the engine oil (possibly a gearbox as well) bring the fan on again. It runs a bit longer than before but it brings the temp down. I think it needs better extraction of the hot air from the nose cone over the top cut out. An additional fan (or two - another one for the intercooler) might be on cards. I would wire them with the main one and as my car does not have a heater, I have a two step switch available on the dash. As far as the track day goes - I've managed to get a set of ZZS just in time, put them on, and it was a blast. Anything less then 24PSI and they were sliding around. Once proper pressure in, very stable. Journey home with stable temps without dramas. A cracker of a day.
