thats a metric guage called Bar

here is a website to convert all sorts of pressures and things

http://www.convertworld.com/en/

most drivers prefer imperial i know i do imperial = PSI

0.5 = 7psi

1.0 = 15 psi (technically its 14.7 but for the sake of easiness)

that website says 1 bar = 14.5 PSI :(

Some say its 14.5, others say 14.7. Who bloody knows. I still round it off to 15 though haha

Just to be an anus I'll clarify this 1 :(

14.7 PSI is equal to 1 Atmosphere of pressure

14.5 PSI is equal to 1 Bar of pressure

I used to think Atmosphere & Bar were the same like many other people probably do, but this is not the case.

Thanks for the claification Jazza. Infact anyone with an AVCR, it reads in kg/cm2 which is less again at 14.2psi. So I was running less boost than I thought!

Yeah I hadn't even bothered to find that one out yet, good to know though. I actually like the fact the Japs use all metric measurement (although mmHg was a bit of an odd measurement for boost, thanks Nissan), it's less confusing, I'm just not used to it. Would be good if we all followed suit.

For me I like it because everything is easier to calculate with metric stuff. With imperial you have to use coefficients all the time to convert from 1 set of measurements to another, it's old fashioned & out of datem & absolutely mad to still be using it IMO. An example is converting CC's to Litres; divide by 1000, piece of cake. Now try & do the same thing converting cubic inches to Gallons.......

This is only the tip of the iceburg when it comes to how logical the metric system is. The only reason we're not all metric with this stuff is the bloody YANKS & to a lesser degree the POMS, who still cling on to some imperial stuff.

Just about every other country primarily uses metric now days.

but really wether ur boost guage says 14psi or 1 bar you dont sit there converting it if it says 14psi

if mine read 1 bar i would want to know how many psi it is

cause for turbos PSI seems more accurate of how much boost you can make and should tune your turbo to

me ive never been into weather so barimetric pressure means nothing :laugh:

just to help clear things up for PRO AERO

The units of measure are: "bar"= Barometric pressure units.

1 Bar = 14.7psi (or so)

psi = "pounds per square inch."

so if a car is running at 0.8 bar, its doing around say 11psi or so but im no good at maths

    • The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.
    • Sounds like the oil pressure light is wired into the oil temp sensor... As it warms up, resistance on temp sensor reduces, hence more current can flow and the dash light gets brighter.
    • Got the front subframe and suspension in.    
    • If it's cold in summer, then no issue. If it's cutting out every few seconds and you're not reaching your target temp, then there's an issue. One could be the pressure switch and the other issue could be the temp probe inside the evaporator.
