my car popped a spring on the seal on the last outing around the track in last few hours, only noticed after we had finished.
but yes all 3 chargers where replacing the seals
mine and andys cars where the only ones still running by end of second day for track use.
liams at the time could keep its silcone pipes on his intercooler that they only fitted before the journey out.
so it would just keep popping off.
i have a more in car footage but its on video and need to get it put on cd first
