Hello,

I just sat down and did some calculations for my Blitz boost controller.

If you have a Blitz item you know it doest read in psi, wich is not great. But in there defence they say that hkPA ( there unit wich 1.00 hkpa is a bar ) is more precise that just reading Psi.

Well heres the chart. *

cmHg - hkpa ( EBC ) ( wich is for Bar )
Kpa - Psi ( wolf)


Psi à Kpa
1 à 6.89476

Kpa à Psi
1 à 0.145038

Psi à cmHg
1 à 5.1749

cmHg à Psi
1 à 0.193368

Boost

.10 (hkPa) Pascal = 1.45 PSI
.15 (hkPa) Pascal = 2.175 PSI
.20 (hkPa) Pascal = 2.90 PSI
.25(hkPa) Pascal = 3.625 PSI
.30 (hkPa) Pascal = 4.35 PSI
.35(hkPa) Pascal = 5.075 PSI
.40 (hkPa) Pascal = 5.80 PSI
.45 (hkPa) Pascal = 6.525 PSI
.50 (hkPa) Pascal = 7.26 PSI
.55(hkPa) Pascal = 7.975 PSI
.60 (hkPa) Pascal = 8.71 PSI
.65(hkPa) Pascal = 9.425 PSI
.70 (hkPa) Pascal = 10.16 PSI
.75 (hkPa) Pascal = 10.875 PSI
.80 (hkPA) Pascal = 11.61 PSI
.85 (hkPa) Pascal = 12.325 PSI
.90 (hkPa) Pascal = 13.06 PSI
.95(hkPa) Pascal = 13.775 PSI
1.00 (hkPa) Pascal = 14.50 PSI

Vaccum

10 cmHg à 13 Kpa
20 cmHg à 27 Kpa
30 cmHg à 40 Kpa
35 cmHg à 47 Kpa
40 cmHg à 52 Kpa
45 cmHg à 60 Kpa
50 cmHg à 67 Kpa
55 cmHg à 73 Kpa
60cmHg à 80 Kpa

Hope it helps a few out there.

I am not liable for any mistakes .
