Hi,
took the 5gt for a track session and all was going very well up to the point we had a quite sudden failure at speed.
first sign was expansion bottle blowing water up through the side of the bonnet at which point we immediately slowed and stopped.
a large plume of white smoke from the rear of the car followed.
car still starts and runs - turbo seems ok.
it's breathing a bit from the engine and its blowing a LOT of water vapour (white smoke) from the exhaust.
so are we talking head gasket or worse cracked liners?
we were running about 15 or 16 psi carb base (fuelling spot on though - professionally rolling road set up)
we hadn't had this GT long so were never sure about the head and gasket in the car.
engine ran very sweet though.
now-a-days what head gasket do people run for high psi?
what other mods does anyone recomend for head or liners?
the planned future spec is to build to allow circa 20psi @ carb base and it will receive mostly track abuse.
we look after our car but we push pretty hard on track too.:)
we need to rebuild so it is as tough as we can make it within reason, the budget is NOT unlimited but we want to do it right.
PS: we took some scalps on track so still came away smiling. :D
