It really depends on the track and car, but I've found that at Le Mans, 1 PR point is approximately 1 second. But I think for some cars, upgrading grip-related parts can improve the car's feel (how easy it is to tell where the limit of grip is and how easy it is to control when you overcook it). The Superfast is incredibly twitchy without upgrades, so it's possible that the improvement was from the car becoming easier to handle just as much as from being technically quicker.
