To crush a small to mid size car it takes roughly 2300 psi. If you want to crush a big truck, SUV, or bigger vehicle you will need more than 2400 psi.
The wolf jaw can produce 3,200 psi pressure which inables it to crush bones and such.
The total amount required is measured in PSI, which is about 35 PSI. Therefore, the amount you need is calculated by using the following formula: Required PSI = 35 PSI - Actual PSI
14 to 18 psi in all of the cooling system
* 1 vertical foot = 0.433 pounds per square inch (psi) * 1 psi = 2.31 vertical feet
350cfm how much psi 350cfm how much psi
Depends on the car and you should fill to the correct PSI level if you do not have a totally empty system.
