How to get better fuel economy on a R32?

[ScarifieR]

hey

just wondering whats the best way to get better fuel economy

i put a bov on the other day and since then i get 45k's to 10 bucks and i hardly give it the boot but i could feel it had more power

now taking it off im back to my 10 bucks to 100k's but can i get even better?

also the bov i used was a gfb basic

would a gfb hybrid or turbosmart dual port be more fuel economic?

need some tips n tricks!

since i got the car ive done these things (the car is fully stock standard)

changed oil (crap valvoline xld in it FFS!) to pennzoil gt performance 10-40 semi synth (gotta change every 5thou k's or 3 months so im not going expensive stuff cause $40 for 5ltrs is enuff)

put a jamex sports panel filter in (felt a touch more power from changing the stock paper 1 to that)

and changed fuel filter

now if there is anything i can do in these regards

A: get more power but keep the fuel economy near the same

or

B: get better economy full stop how it is

thanks for inputerers

change fuel filter

get injectors cleaned

get an aftermarket fuel controller to change fuel curve

drive off-boost

externally venting bov wll use more fuel cause of air going past afm and not into engine...

makes cool backfire noises to go with the woosh tho..

who ever said these cars were suposed to be practical?!?!

Always use the factory Nissan BOV the after market ones are for noise only.We have some very big Hp cars still on factory BOVs

one is 400rwhp.

retard timing, reduce boost, and use std unleaded....

or you could drive a Hyundai - probably equates to about the same thing

your could do what adam said earlier while sticking with the stock bov

ie drive off boost as much as possible and get a SAFC or SAFC 2 or similar fuel controller.

i get have an average fuel consumption of 9.6L/100km. granted the majority of my driving is cruising up and down the freeway.

hmm i think i need to do something to my car, i go up the freeway from rocko everyday like you sykyzer and can only get about 8km/L, tried a tank of normal unleaded too without any messing about and still got the same.

you can't really complain, you buy a skyline you live with the consequences

I cannot beleive that people do this to their cars...

Scarifier, do not try this. Not under any circumstances. not even a little bit.

[RadiuM]

bah, that was the only time i did it and it was to see if U98 actually does increase fuel economy as it says on their brochure.

but it still ran fine... not a sign of knocking/pinging at all. It was all granny driving that week as I was seeing if i could beat my ~430km/tank, but no luck

you would definitely NOT do it during summer though.

[adam 32]

you can use std unleaded if you retard the timing... as long as it doesnt ping then itll be fine. i dont recommend filling up a tank of unleaded and then going on a night cruise or anything

i cruise up and down the freeway too.. I get 500km to a tank, that's like 7.6L/100km. I'm going to granny it all week and see wat I can get... fear the 600km limit!!

me thinks we have written this wrong kym.

kym

500km/65ltr = 7.6km per litre

Me

600-620km/65ltr = 9.6km per litre

as i said

i could feel it had more power cause my standard bov doesnt hold boost!

it only sits at 5 or so

never locks to 7

(on dash guage)

but the after market 1 did

thats the reason why i changed but the fuel economy just put me right off

[quink]

mmm.. i just had my R32 for about 2 months now.. haven't been able to get it under 13L/100kms!!!.. i've tried to granny it.. but i can't help goin on boost for a lil bit.. but from the sounds of things mines using too much fuel? what the... i dont have a boost gauge but the lil crappy stock thing points just below 7 on full boost.... (so has the boost been upped?)

[ScarifieR]

well i just worked out

i went to perth n back

did 520k's

cost me 50 to fill up there

49 to fill up when back

that equaled out to 10.27k's a litre

and i gave it a bit of curry in perth but not full on

so beat that

[caminperth]

me got over 600kms last time i went down south.. and that was long extended periods at a decent speed.. ie 4000 to 4500rpm in 5th gear.. i was quite suprised.. seems the engine either likes these sort of rev or thats the only rev point at which my fuel map is sorted..

methinks the second one..

[ScarifieR]

mm

i sit at 2900rpm going 110-115

with overdrive on

off prolly 4500+

[R34]

On Holidays down south I managed 720kms to a tankful with my old 33.

im luck to get 350 Kms from a full tank in my 32 and its not even turbo

u want a performance car u have to be prepared for the concequences

more power = more fuel

simple as that
