1 Kg/Ccm^ = 14.22 PSI

1 Bar = 14.50 PSI

1 ATM = 14.70 PSI

And for those with Blitz controllers:
1.01325 hkPa = 1013.25 hPa = 14.70 psi
1 hkPa = 1000.00 hPa = 14.51 PSI

Seems right, butttt

Im seeing all the way up to 1.1 hkpa, which is about 15 psi on a stock setup. Either the boost gauge is inaccurate, the calculations are incorrect, or there is a problem with the car itself.

All i have is a Apexi GT Catback, BOV is disconnect from airbox also. Is it possible a crack or disconnected vacuum line is the culprit? (maybe the green and pink ones in this diagram? http://home.earthlink.net/~quicksilv...se_diagram.jpg)

 

also, would i hear a beep from the engine bay if I was overboosting? I do not hear one. 1993 rx7 base

 

Attached is my calibration for my Autometer boost gause to Blitz to PFC.
1.1 hkpa/bar = 16PSI boost.

 

n/m.. ignore this..

 

Just went out and drove it, this time I seemed to get a fuel cut, or some sort of hesitation at about 4,000 rpm, could've been the primary turbo tappering off, but it sure did not feel like it. I let off the gas after the hesitation.

Im just baffled how I could be getting this insane boost creep. Any ideas?

 

Well i bought a different boost gauge and hooked it up just to be sure the readings were accurate.

I boost up to 12 psi pretty easily, maybe 3/4 throttle. At 12 psi at about 3900-4000 rpm, I get a fuel cut. One time before I recall the fuel not cutting. Went close to 15 psi.

Again my setup is stock minus the Apexi GT catback...and my bov hose is disconnect from the airbox. The ECU looked stock, although I did not unscrew the cover. What exactly causes boost creep like this? What should I be looking for first?

 

If you are boosting over 12psi on the stock ecu then it will go into fuel cut. If I were you I would purchase a after market ecu like the pettit or m2 or if you want go with the power fc.
