Iirc correctly Fred the car boiled itself at that race but he couldn't be sure of temps due to dodgy sensors etc then it spat a rod next time out, more than likely the oil taken a roasting didnt help that.
I think its unfair to say a car doesn't need one Tony when your running one of a different type.
Thermostatic plate and you'll never have to worry IMO.
nope, it did the oulton park race after donnington, then a full day round the ring, then spat a rod after half a day at spa
