ive just fitted a psi boost gauge. and might i ad it was very easy.

my question is what should the boost gauge read on full boost???

it goes upto around 15 psi on full boost. is this normal?

my car is a wrx import 95. with no engine mods.

many thanks gaz.

 

i need one ov them where do you get them from ??

are they easy to get hold ov ??

which are the best ones ??

 

stop taking the pi$$

 

if the car is standard than max boost should be 12.7 psi.

 

errrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr


IM NOT !!!!!

i av only ad my car since Dec and i know nothin about scoobies

 

the car is standard. when on full boost the gauge goes to around 14/15 psi.

ive had no engine mods at all. why is it going this far. could the gauge be faulty??

 

sorry m8 i thought you was trying to wind me up. im no expert myself. i got someone that has done it before to show me how to fit it. post a thread in the wanted section im sure someone might have something for you. or try ebay? good luck.

 

does anyone know what 1 bar is in psi?

(not a joke)

stew

 

1 Bar = 14.50378 psi

 

I thought a 95 was meant to go up to 14.7 psi - if so yours is bang on!

14.7psi is 1bar.

 

can someone answer my question please.

if standard is 12.7 why am i getting 14/15 psi on the gauge.

 

De-cat ups the boost a bit. I seem to remember getting 14.7, and I had a MY95 fully de-catted. So perhaps 12.7 is standard, and naturally ups to 14ish if decatted?

 

forgive me for being stupid here. but is that good or bad????

 

thanx i wasnt been funny

hows the black scoob then. still covered in snow.

 

Its fine matey!! In fact its better than fine, as if you were running 12ish psi (which apparently is standard) your car would not be as rapid!

I just did a search for you, and David at API engines said somewhere that you shouldn't go over 1.1 (16psi) bar for long periods (unless you have changed a lot of components etc.).

Yours is 1 bar so no probs.

You don't want to go over 15psi, as the fuel cut on your ecu (Z4) is 15.65psi. Fuel cut is your ecus safety mechanism for restricting boost, and would feel a bit like a rev-limiter kicking in.

So yours is fine.

 

I just re-read your original post though, and you said the car is standard? If it is standard then you should be hitting 12.7max.

However, as I said above, if its been de-catted (or maybe has had a manual boost controller fitted) then it will be higher, but so long as it stays below 15.65 (fuel cut) shouldn't be a problem.

 

i have a 95 wrx import and the standard boost for these cars is 15 psi just over a bar imports get more boost than uk cars. uk cars only get about .8 to .9 ur car is fine

 

your a star m8.

all is as should be then.

thanks for your time

 

no thankfully lol

was lookin good on the rollers this morning

 

so what are you doing to it now. or what have you done to it now.

 

ive done nothin to it yet want some new wheels an maybe a remap

not too sure yet

 

go for the wheels fare cheeper in the long run.

go for remap and you will want more.

 

errr......no i think you find these are the boost pressures:

WRX (1992/1994) ECU's 2C, U8, W6, W9 - 11.47psi held to redline. Fuel-cut 14.57psi
WRX (1995/96) ECU Z4 - 12.71psi, dropping to 11.78psi @ 6600rpm. Fuel-cut 15.65psi.
UK ECU's V7, 7D and 6D - 11.47psi, dropping to 9.47psi at 6600rpm. With Fuel-cut @ 14.87psi
UK Prodive ECU - 13.33psi (peaks to 13.64 @ 5600rpm, drops to 12.71psi @ 6600rpm). Fuel-Cut 15.65psi.
STi RA (1996) ECU 7K - 13.17psi (peaks to 13.64psi @ 5800rpm). Fuel-Cut 15.96psi.
WRX Wagon ECU V9 - 10.55psi dropping to 6.84psi (starts to drop @ 5000rpm). Fuel-Cut 13.79psi

 

what a load of ****e so u know better than the subaru experts then as they are the ones that say it is 15psi standard

 

ha ha ha you are having a laf arnt you? which subaru EXPERT has told you 15 psi?. please tell me?

 

just to ad. i run a 1995 z4 ecu

 

i dont give a **** what u run i was told that from people that know alot more than u david at API told me that wee boy

 

dude, chill out. david built my engine! I think you have mis understood him, or he has his lines crossed. Why dont you ask around a bit more eh!? wee prat

 

dont need to unless ur saying david doesnt know what hes talking about. if u know so much mb u should see david about a job
