I am purchasing the hka boost gauge but it is measured in this stuff called KPA and the gauge only goes to 1.5 if my car is gonna run like 16 pounds of boost how will i no if it does go that hight does like 1.5 mean 15 pounds of boost i am confused some one please explain this to me before i get it
The gauge is probably calibrated in "bars". 1 Bar = 100 kilopascals (kPa). 1 pound (pound per square inch or psi) of pressure = 6.895 kPa.
So the maximum reading of 1.5 bars (150 kPa) converts to 21.75 psi.
Check with hka to be sure it's graduated in bars.
weindan has got it right. hks does a lot of its stuff in kpas because the rest of the world uses the metric system and we stupid americans can't accept that it's better. my suggestion, don't get something unless you can get it in psi.
boost, i didnt want a guage in bars had hard time finding a small guage in psi, so my fix was i bought the subaru replacement console for the clock without the guages for like 45 bucks made my own face plate installed a auto meter guage and clock in it, works great looks good, IM me if you want a picture.
