Very little blowby this time filled my catch can about 1/3 full in the whole day. The car ran really well with water temps peak around 82-90 all day, ait around 10-15 and boost held steady at 1.2bar without the random fluctuations I sometimes get on hot days.
I've proper killed my brakes though, they sound like someone rubbing steel across concrete. That's 3 trackdays and less than than 2k miles on £600 worth of new discs, pads fluid the lot. I am now going to look at different options as this is no good to me.
