Poor Fuel Economy Gtr

[gtrzilla]

im going to try a different fuel i think

ive just filled up with Mobil Synergy 8000 or whatever it is, we will see how that goes

also, cos its been so hot lately, ive been using my A/C heaps

im going to see if out of a tank i dont use it at all and see what difference that makes

^^LOL! Nah bro!

The Stock boost gauge is measured at -0.7 / 0 / +0.7 Bar.

So +0.7 Bar = 10.5 psi

N1 GTR's are the one that run 1 bar.

"Yah bro!"

Its mm of mercury...

Trust

Me

I have a HKS Boost Gauge

The pointer goes only up to where I have circled, which I believe is +0.7 Bar = 10.1 Psi.

Just help me clarify this cuz Iam interested to know...

Thanks!

[gtrzilla]

yeah thats right

im just sayin that +7mmHg = 1 bar = 14.7psi

you originally wrote that the gauge read +7 bar = 98 psi

^^Ah ok!

LOL! Yeah I tried to clarify that in my 2nd post... But any way, Cheers!

[gtrzilla]

anyways

we have gotten totally off topic

but yeah , without the air con my car is getting heaps better k's

Also, don't bother saying how many KMs you get to a tank. The best way to work it out is:

1. Fill up to a full tank

2. Reset trip meter

3. Drive

4. Fill up, note how many litres it takes

5. Do this calc: Litres divided by KMs ... then times that figure by 100 = Litres per 100 KMs

The reason this is a better comparison is that one mans "empty" is different to another persons. For example, I normally get 320kms out of a tank... but I never take mine to RIGHT on the E mark, and I put 42-46L in it.... so around 13 - 14 L per 100kms, which is around normal for a mildly modified GTR IMO.

yeah thats why i said removing the restrictor makes you run 14.7 psi

not saying that is a good idea

what im saying is that the gauge is in mmHG not bar

7 mmHg = 1 bar

May i ask, where is the restrictor that you remove to get full boost?

May i ask, where is the restrictor that you remove to get full boost?

I was told, it is where I have circled...

[GT-R 32]

my 32gtr is pullin 400km's for full tank. all i had done was injectors cleaned, changed air filters, o2's,

i give it a fair bit of push around suburbs.

but yer my injector is now leaking out fuel i assume this time round i wont be gettin 400k's.. what is it i need to replace .. O-rings for it? and is it hard to replace?

i just got a power fc installed + car tuned.

driving sensibly im now getting around 420 to a full tank round town.

i've been giving it a hard time this tank and it looks like it will hopefully still be around the 320 - 350 mark.

car is almost stock - 222rwkw @ 12 psi.

hope this helps.

also, check your comp - is it standard? my old cpu was the main cause of my previous poor economy (around 300 to a full tank barely hitting boost).
