A fair few more than 150amps mate....
The 150amp fuse will not blow until it reaches around double its rated load....
The pic you linked to was based on a small engined Vauxhall, the best advice would be for you to check the stock battery specs for your car...Take note of the batteries CCA rating, this gives an indication....
The initial burst only lasts for a short time, once the engine is spinning the draw drops markedly....
It's good practice to start the car with the clutch depressed, this eases the load considerably....
I would suggest you consider a circuit breaker fitted at the battery in place of the fuse, if using 4awg cable, (battery to engine bay), then treat 150amp as a maximum, if using 0awg then 250amp maximum....
