ok so ((2psi/14.7)+1)x8.5:1=9.656:1 that dose not seem correct but owhell.
So what i was thinking now is if I wanted to add boost I could run a system using my O2 tank from scuba diving that runs at 3500psi and has 100Cu.ft and rework an old regulator to give me as much boost as a want the only trick is setting it for different trottle possitions to open. When I dive with a tank at 3000-2800psi and 80Cu.ft it lasts me about 45min breathing 35psi at atleast 2-3x atmospheric pressure and never running lower than 600psi. So I figure running 10psi or so at arround half throttle would last 3-4hrs at that possition if not longer and more with the larger tank.
I think this would be fun to try some time the tank only weighs 30lbs for the 100 or 35 for the 120 and a fill is only $5 I would rather do this than just spray since i could feather the boost in by a vlave and run it for a week or more depending on how i feel like driving.
Now that i am finished rambeling any thoughts would be good.
