accumulators are nice, especially in drag vehicles, you can "pre-oil" them before cranking over that high compression engine. The only down side to it in this application would be that if you lost enough pressure (i.e. your oil level some how got really low) and you didn't notice RIGHT AWAY it would only give you an extra minute or so of safety. In the drag racing world that's plenty long seeing as most cars that run this type of setup are only running for about 8 seconds or less at full throttle (haven't seen too many of these on "slower" cars but a few people still run them for insurance, even then your talking like 11 seconds or faster). Now if you could make the reserve a bit bigger and run an LED "shift" light that's bright enough to really warn you whenever the system had to be activated, that would work. I'd just be worried that your flying around the track, it goes off and you don't realize it in time so it doesn't really help.
