limit is 86% of 93 psi = 86/100 x 93 psi ≈ 79.98 psi As the psi is measured to the nearest 0.1 psi, the safe limit is a measured 79.9 psi.
Formula: psi x 6.895 = kPa
10 psi.
Inches of water x 0.03613 = psi
Use this formula: psi x 0.07031 = kg/cm2
145 hp and 195 ft-lb torque from factory at 7 psi boost.
The 87 turbo z was 6.7 stock, but when they get older they could lose boost do to age. It could also be your stock boost gage not reading the correct boost. You should buy a after market boost gage and a boost controler, with a high performance exhaust, intake from K&N and a boost controler you should get huge horsepower gains. Just make sure you dont go over 11 psi without an intercooler and run high octane gas. If you want to go over 8 psi, you will have to remove the stock pop off valve.
There is no direct conversion between horsepower and psi as they are not equivalent units. Horsepower is a measure of power, while psi (pounds per square inch) is a measure of pressure. They represent different physical quantities.
the normal boost is 5-12 psi. the normal vac is about 18-20 psi
The total pressure at sea level is approximately 14.7 psi (standard atmospheric pressure). With a boost of 8 psi from the turbocharger, the total pressure being fed into the engine would be 22.7 psi (14.7 psi + 8 psi).
Boost level is controlled by the wastegate on the turbo. The wastegate should start to open at 15 psi and fully open at 20 psi. This is to keep from over boost that was set by the factory.
HP is not determined by PSI.
Boost refers to the forced air induction, the greater the boost the greater the PSI of air being forced into the cylinder.
39 PSI according to my Chilton book
12 psi in both ranges
0.524 kg/cm2, or about 7.5 psi
14.7 psi
