Sounds like you might have a pneumatic leak somewhere. We have been able to hold at max pressure without running the compressors for... 3 months (at least). Looking for that tiny elusive leak might solve the problem of constant compressor running. Either way, I wish we had the commitment to make something that awesome...

Thanks for the comments and I'll try to respond to all of them.
First of all, I should give credit to team 1716 and this for inspiration. We are using 2 tanks for two reasons:
The system is all 2" schedule 40 galvanized steel pipe except for the brass ball valves and the ABS barrel. The 2" ball valves are opened by 1.5" diameter 8" stroke pistons. We could not locate 3" galvanized for the barrel locally and buying it on line was too expensive. Yes we have a leak somewhere in the system. Also, four of the five compressors filling a tank took 15 seconds to reach 120 psi. We had some serious run time regardless of the leak during the game. We are scheduled to be at this Friday's game as well and we are taking measures to improve our performance. We haven't done much driving on the track except straight forward and reverse, it accelerates pretty well (~20ft.). Our best shot was firing both tanks at the same time, one was at 120 psi the other was at 135 psi. I'd say it was about 90 yards with the barrel at a max elevation of 40 degrees. (For those of you wondering, the galvanized is rated for 180 psi and we have pop-safety valves on each tank that vent at 150 psi.)::safety:: |
