4 million bar!......

Phinx made 150rwkw on 0.5bar and managed to crack a ring landing at what most consider "very low" boost

Its more about how much power the motor is pushing at a certain pressure more than it is about the boost pressure itself, remember boost pressure is the motor natural inability to "swallow" the amount of air given to it.... little food for thought....

so what you saying is that one should 1st prep the motor before upping the boost? or take certain precausions?

You're looking at buying a fairly old sports car so taking extra precautions is definitely a good idea.

Yes and no... Guys in the UK run 0.8-1.0bar constantly without problems, but they have thicker air, most fit FMIC's prior to doing so, and they have very little problems or none at all...

Here by us (guateng), your turbo won't last long on 1Bar if you can even get 1Bar, then there are guys that say they have been running 1bar for years without problems on a completely stock motor...

It all depends, how your motor was taken care of, and what you are doing to prevent knock... and of course how your turbo copes with the extra load

so by me staying at the coast (Cape Town), it should decrease the problem factor when increasing the boost.
the only people i would consider buying the car from is either an inthusiast or an older lady or man who had the car since new!
