How much psi can a bicycle foot pump produce?

Question

I just want to know beacause I'm going to try to upgrade my water gun lolz. I know this sounds really dumb but yeah. Or i was thinking like my own weird water gun battle armor lolz. Something like Iron Man i was shooting around the idea but I really don't know much about water systems and psi >.< So can ya help me out folks? I'm just another kid with another weird idea. ;]

Answer 1

If it has to fill up high performance road touring bicycle tires (in addition to off-road mountain bike type tires), then it can produce in excess of 100 psi.

(My tires take 90 psi -- tour-de-France class bikes sometimes operate as high as 120 psi).

But, keep in mind that at 100 psi, the volume of air per &quot;step&quot; of the pump, is tiny.

Answer 2

My Joe Blow pump goes to 165psi.  You can try a Crank Brothers mountain bike fork pump if you need more pressure they go up to 300psi

Answer 3

The pressure of air (14.7 lb at sea level) multiplied by the compression ratio of the pump.

Can&#039;t get closer than that because of the very great range of pumps available. Maybe if you describe your pump, I maybe able to help (or you could buy a calculator).
