now i know there is an equation for this but i dont know it and i suck at math. where can i find a table or something so i can just look it up if i need to. i know stock evo boost is like 1.35 or so kpa. mine was holding steady boost at 1.42 today with this spiking *** profec B. just want to know what about 1.42 is in psi so i know if this was too much. i know its cool to go up to about 20.5-21 psi for a second but then it should drop back down to about 20 to be safe. i cant dial it in well enough with the profec b to stop it from doing that. i have an HKS EVC V just havent installed yet. anyway what is 1.42KPA in psi???

I believe your seeing 1.35 bar.

Where 1 bar = 10^5 Pascals and
1 PSI is 6894.76 Pascals so

(bar*10^5) / 6894.76 = PSI

Where you just plug your value in for "bar" in the equation above to get PSI (the ^ is a exponent).

So 1.35 bar would be 19.58 PSI.

1.42 * 14.5 = 20.6 PSI

MasterTLT

Thus 1.42 bar is 20.595 PSI (kpa would be kilo pascals, or a thousand pascals, bar is actually 100,000 pascals).

ok thanks a lot guys, thats not as hard as i thought it was. i suppose holding 20.6psi isnt so bad but could be a shade lower. it held that boost when i punched it in 5th gear. if i keep the same settings on my profec B II and start hard off the line, i wont even push stock boost. hows that for inconsistency from a boost controller??

try playing with it a bit... i know how you feel though, my profec b is seriously retarded.
