Last week I was on a road trip which involved about 2000 kms of driving. The outside temps were about 30-35 degrees celcius, very dry. My a/c doesn't work, so that was never on, just my vent. The drive involved long steep inclines, and I was hestitant to stay in much boost for too long. Guess i'm scared of blowing something up. For a car my age, 1988, with probably the stock turbo and 174,000kms, is it ok to put your foot to the floor and keep it in boost for lets say a minute or two?
