turbo timers? are they worth it?

[Dave]

Not worth it, only worth it if your car parking space is at the end of a slip road. It's when your on boost for like 30 seconds and shut it off. Being on boost and then just letting the revs back down is enough to stop the turbo speed right down. If you've been spanking it all the way and then shut it off as long as your turbo speed is back down which happens in 2 seconds then wouldn't worry. It's more if you shut it down while on boost damage is done ...
