G40 boost preasure

[budunt121]

i get 9/10 psi with a standard charger that needs a rebuild and running a 65mm pulley with jabba chip and g60 style belts and the gt inlet

i get the same 0.9-1bar near red line with a 65mm pulley,r1 charger,standard v belts with beltslip spray on them

[budunt121]

i would have thought you would get more with the r1 charger , i dont know if i should rebuild mine or go for the r1!

[poloandyb]

their all about same to be honest from what i can tell,my mates got a full blend and he's running about the same.

Don't forget that if you've got ported bits your boost may drop relative to others.

[PeteG40]

theres a big difference from 9psi to 0.9 bar - 1 bar is 16psi.

You see about 0.2 bar difference with a ported charger

[dub-disaster]

I thought one bar was 14.7 psi  ?

[Jezza-7]

I thought it was 14.5?

14.5...ish

Sorry Pete!

Normally 1 bar is seen as the pressure of the earths atmosphere at sea level, which is 14.7 psi, but 1 bar actually equates to 14.5psi.

Justin - you're confusing bar with atmospheres. Bar is an SI unit, so its definition doesn't change, atmospheric pressure at sea level is about 1013mBar.

[Justin14100]

Yes, and 1atm is 14.7psi - which is why people think 1 bar is 14.7psi - because 1bar usually is just accepted as the pressure of the atmosphere. hence the misconception.

[PeteG40]

my bad - 14. whatever.

even so... 9 psi wth a 65 is low

[scotsjohn]

Would 1225 Torr sound better? lol.

[budunt121]

i thought it was i may just rebuild this standard one unless i find a cheap r1/full blend
