Excessive white smoke on full boost?????
When putting my foot down am getting a puff of white smoke which I assume is coolant however I've checked the coolant level and it seems to be normal.
It only seems to happen under full boost.
E.g driving along slowly and then planting my foot down puff of smoke under heavy load. However once am up to speed theres no issues?

It only does it on full boost under heavy load a big puff of white smoke covers the rear wind screen and then it clears up and is fine after 1st and 2nd gear.
Thanks for all the help guys on new years days

It's certainly can't be counted out that it's the turbo but unlikely.
You have to remember that the heat an exhaust will see is worlds apart when stood still reving to when being driven under load up the road,if you haven't already I would take it for a good long drive ie 50+ miles and see if the smoke is still there,if so I would looking to take the down pipe of to see if there is any signs of water/oil there.

Unburnt fuel is also white. (eg: hot exhaust and not enough spark energy - i.e flooded)
But you have to dump a serious amount into the exhaust for that to happen (like what Classic scoobs do on a winter cold start).
Its only black smoke through combustion with a lack of air (rich but good spark - not flooded).
It is quite dense though, denser than steam, but not as dense as oil smoke, and if you sniff the tail pipe, it'll stink of petrol.

The car has a slight hesitation as tho theres sh't load of fuel being dumped in.
