Stagea Fuel Economy

[rb26stagea]

Ok - did the experiment, and drove for about 1/2 of my weeks use on high boost (normally only do maybe 15kms in high boost - and use low boost most of the time when cruising), and refilled after 3/4 tank. extrapolating the use, I would have gotaround 510 km from this last tank - 100km more than running on just low boost. Also, I never knew the actual tank capacity, so have been basing everything on a 60L tank.

I filled up today, so will try a whole weeks' worth of driving using only high boost...

When are transmission services usually due?

Once a year. I'd highly recommend you dont ignore it. Its as important as servicing your engine IMO.

Be aware some places will say they do "transmission servicing" but all they do is change the fluids. To get a proper service done, take it to an auto trans specialist. They will actually open it up and inspect it/tighten bands as needed etc. as well as changing the fluids. You get a more thorough job done if you take it to an auto transmission specialist. Average cost is about $130-150.

Since driving my new manual Stagea I've noticed my fuel efficiency has gone up from 17L/100km to 14L/100km. This is just from initial observations, but looks good

do you mean has gone DOWN from 17L/100KM to 14L/100km?

Sold... I'll book in MV Automatics Blackwood and get the shift kit too.

I think he means fuel efficiency has gone up, as opposed to fuel consumption going down

I drove down to Newcastle from the Gold Coast last week and achieved 9.3k/lt or 30mpg. 460k's from 43ltrs I am pretty happy with that cruising on 110kph.

Exactly

jesus thats awesome economy !!!

i get 320 to the tank on my cedric

my stagea still only gets around 200km

but hopefully that will change by next weekend

[rb26stagea]

Ok - I can now categorically state that high boost is NOT the most efficient setting on the highway - only got about 400km this tank, and did more hwy km's than average..... So, high boost for hills and round town (just not stop/start), and low boost for traffic jams and hwy....

Next weeks episode: I am going to change boost settings depending on road conditions, and see if I can get more than 600km out of the tank!

After now owning our S2 for six months, I have found that city driving is VERY different to going on a country run. Around the city, driving what I call "Normally" (which includes blowing the odd shithead away from the lights or stopping them cutting me off). I find I can only get about 360kms per tank. If I can go a whole tankful and not put my foot down I can get 420km, on a run at a constant 110kph, we can manage 525km.

So I wouldn't mind betting that it's the same with guys. But I didn't buy a performance wagon, just to watch how slowly the gauge goes down. I have a falcon on gas, if I want around town economy. With the Stag I really think that it is the short runs, (traffic lights and constant acceleration) that kill the economy. I am still working on that method of being able to earn money faster than I can spend it..... in this regard the Stagea hasn't helped!!

Pretty much exactly the same as you. Do you have many mods on the car?

I've also found different fuels (98ron Shell, BP, Mobil - in that order) give different mileage too.

Thats exactly the economy my series 2 gets. I earthed the boost solenoid last week, so am interested in how that affects economy. I have a theory (untested) that having higher boost coming on early will assist in moving the weight of the Stag up to cruising speeds easier, so therefore the fuel consumption my even out, or even be slightly better. I will let you know how it goes. It certainly helps the driveability, and means I dont have to sink the right foot as hard as before.

I havent done a trip in the car since getting it a year ago. I was hoping to come up for the skyline show & shine, but had to miss that in favour of the rugby test.

I would love to do a tour (if anyone is interested) from Canberra to Moss Vale & meet up with some of the Sydney guys - then drive down through macquarie pass to Wolllongong, down the coast to Nowra, then up Kangaroo Valley, back to Moss Vale then farewell each other at the highway. I will put up a separate post to see how much interest there is. There are some fantastic roads for the Stag to enjoy there.

Very interested on seeing how this goes with consumption. Keep us up to date. My only worry is that the boost will come on too early while cruising on the highway (110kms @ 2500rpm) which might be detrimental to the solenoid or something else maybe? Why else would they have done a 2 stage boost as stock?

[Appealing]

I earthed out the boost once, just before going to the drags, only to have a really bad misfire come on. I must admit that I also put in about $20 of 95 octane, and at first thought that it might be shit petrol.

But it ended up being spark plugs. I just can't help wondering if using higher boost at lower revs had anything to do with the plugs stuffing up though. I only did one run on high boost at the drags, then pulled the wire out, but the 2nd run was just as bad. Then gave up and went home.

My car BTW doesn't have any serious mods, only an exhaust (& turbo timer!!), and to be honest I am not sure of the extent of the mod to that, as I cant get under the thing 'cos of the body kit. I'll get it up on a hoist soon!

[Silverback]

I havent had any problems whatsoever with the solenoid mod. The car runs great, and taps into the torque a bit earlier because of the slightly higher boost. I have a split dump pipe, full 3" highflow exhaust with hi-flo Cat as the only mod. I only use Premium unleaded to refill & use Mobil 1 synthetic oil.

In relation to solenoid performance, I cant see a problem there. The solenoid is an electrical component with no moving parts, and is not likely to suffer from "wear & tear". I do ensure that I stay off the noise pedal when the Stag is cold, but that is actually easier now that boost comes on quicker.

In relation to highway performance, I would consider it an advantage. For overtaking, you have the boost in the optimum range earlier in the revs, and its not like the car is sitting on full boost at 2,500 - 2,700 revs and cruising. Only when you put the foot down does the turbo spool up a bit quicker. In any case, its not like I am getting into the unsafe/unreliable range of the ceramic turbo, as it never goes past 9psi in any case.

I am halfway through the tank, & will post up results soon.

what are your gas prices like to care THAT much about every little ounce of gas mileage

I pay 143 yen a litre of gas

68 liters

and i get 350 on the cedric last tank

and i think its good!!!

the stag gets like 230 on a good day

horrilbe

but seriously, what is yalls gas prices. and how do you get upwards of 400KM a tank?

are you stock or modified alot?

Stock S2.

At the moment, about AU$1.30-$1.35 for 98 ron fuel in Adelaide.

[leetom]

i have a manual bc set at 10psi and consistantly get 500km to a tank (full ces system)
