I was recommended by some friends to get a greddy or apexi boost gauge instead of autometer if I wasn't pinching pennies, so I went ahead and ordered the greddy boost gauge... on the website it's really hard to get a close look at the boost gauge... is my gauge the one everyone receives?... the gauge only goes up to 2.0 and is in kg/cm2 (squared) units... I was expecting lbs/in2. Are all greddy gauges like this??? do any of the greddy boost gauges come in psi units? Also, what is the conversion. how many psi of boost is 0.5 kg/cm2.... 1.0 kg/cm2.... 1.5 or 2.0 kg/cm2? Should I keep this gauge, or send it back? I guess this is probably a newbee question, but I would appreciate any help you guys can give me...

Thanks in Advance,
Zack

 

Yes. I believe none of them are in psi. It's cool you know, but when it comes to tuning and looking for advice, it just takes another step to convert it.

I have the AutoMeter Boost gauge and it works really well, showing up to 20 psi of boost and 30 thingies of vaccum.

 

1bar is 14.5psi....

 

Here ya go pretty simple enough:

.4Bar (5.8psi), .6Bar (8.7psi), .7Bar (10.2psi), .8Bar (11.6psi) .9Bar (13.1psi), 1.0Bar (14.5psi), 1.1Bar (16.0psi)

 

Thanks a lot guys... I just looked on Apexi's website and it says you can get their Mechanical boost meters are available in PSI and KPA... which are better, mechanical or electronic? Also, does Greddy also offer in PSI and KPA for mechanical? what is your guys opinion on this?

 

i use a mechanical, because i heard it was easier to install, but i don't know anything about the electrical, so i guess im lost there.

 

Actually to get technical 1 bar = atmospheric pressure = 14.7 psi

 

is there a BIG difference in what kind gauge company it is? in my opinion, they are all the same, work the same....just different looks. i got carbon fiber autometer gauges and they lookin tyte in tha nite.

 

.1bar = 1.422334331psi

its not that bad once you use it.. pressure won't jump all over the place.. readings in bar matches standart wasteage spring setting anyway..

 

Greddy boost gauge is not in BAR it is Kg/cm2 1=14.22

Same thing bro

 

Nope, not that it is big deal but a BAR is 14.7 psi while kg/cm2 is 14.22psi

 

you make a good point. nearly exactly the same tho I am very suprised that they are indeed not the same

 

LOL! sorry not trying to be ****! But every tenth counts especially on stock bottom end KABOOOOM!

 

thats a good point.. although i used kg/cm2 which i though was the same as bar..

so its .1 kg/cm2 = 1.422334331 psi
