Outer Limits 4x4 Board

I have a GQ with a td42 turbo an intercooled with a 3in exhaust, an on a trip down south it was using about 16L/per 100kms, is this normal?

A mate has given me a 350 chev block with 4 bolt mains ( i have to put heads on it) and was thinking about building this up and putting in the GQ. What kind of fuel wound these normally use in this application? ( nothing to wild with engine mods planned just yet)

Any help ould be greatly appreciated..

Go to marks adaptors site, they have some info on this mod I think.

Their will be lots of people keen on your motor turbo and intercooler

If you replace it

Yeah no worries will keep you informed, its just done 100,000kms.

How ya doin

I have a 350 in an MQ and it is really good on lpg (GAS) I get more km's around town as the motor is not reving as hard, but I would get around 300k (gun it every where ) around town, and about 270k on the hwy (dont know how far, no gauge and I dont want to run out), this is for an 80ltr usable tank. I am about to put 35's on and will have to take note of the difference... Also note as my speedo is already out, the trip meter I would say is out also, this is with 31's. Generally I sit on just above 3k on the hwy at 100km, hopefully the tyres will make a big difference hwy driving.

So around town its less than $40 to fill to do around 300k+ wich I think is good. As it has oooooodlllllleeeeeessssss of grunt every where...
I dont know what it would cost to run on normal unleaded as its not set up for fuel...But would love to try one day, should give it a little more grunt again, lol........

Daniel,
The economy of your TD42 seems a bit high. I'm getting approx 10-11 litre per 100km of highway driving in mine, and approx 12-14 litre per 100km of city driving.

TD42, hi-flowed turbo, bigger fuel pump, 3" exhaust etc. No intercooler though. Bigger fuel pump made a significant improvement to the economy after I hi-flowed the turbo....now sit at 110-120km/hr using 1/4-1/3 of the throttle, instead of 1/2-3/4 throttle. And as mentioned previously, it does overfuel off idle, so economy could be better yet.

Can't help with the Chev economy sorry.

Cheers
Mitch

"350 Chevs" and the word "ecconomy" dont work well in the same sentence !

if you want ecconomy stick with the Turbo Diesel

If on the other hand you want grunt and horses to spare & luuuuve the idea of smokin up 35" BFG's ........ and you have shares in BP / Shell / Mobil etc .....Chevs rock !


To get ecconomy (well savings at the pump so to speak) you'll need to run LPG with the chev.....& probably for the engineers cert too


their still making petrol so I'll keep burning it

Kingy

just do it

Thanks for the info guys , i will keep you informed with whats happening

Kingy, why would you need gas for the engineers cert?

Hey,
I have a GQ with a 305 on sraight gas. Normal Driving I get about about 300km for between 60 and 80 litres. About 20 - 25 per hundred kilometers. I was out 4x4ing on the weekend at colo and it was a lot of uphill rocky low range work. Besides the overheating of the engine a pit I got 220 km and filled up with 77 litres of gas. But with all the power available and the great sound it is worth it.

emissions i believe... gotta pass em ...

AndrewPatrol wrote:Kingy, why would you need gas for the engineers cert?

The engine is older then the car - legally you cannot put an older engine into a newer car, and hence the only legal way to get an old clunky V8 gas guzzler into this car is to convert it to straight LP GAS, as it will have near zero emissions.

AndrewPatrol wrote:Kingy, why would you need gas for the engineers cert?

As the others said ....it will be a nessecary item if ( & I mean IF ) the engine is OLDER than the rig its going into.

It wont have a hope in hell of passing an engineers test if its NOT ON LPG.

There is a way around it tho and its simple ...fit a new 350 chev along with all the polution shyte and ya laughing.

Whats the engine number on the block From that number we can figure out which year it was made, also get the "casting numbers" on the block and the locations of those casting numbers.

With all the numbers we can get right down to which make / model / year it was designated for originally

My 4bolt 350 has a 1971 light commercial truck designation....yet the heads were about 10 years after the block was cast !

Once we know what year it was cast then we can figure out whether it will have to run on LPG or not.

Kingy

Thanks Kingy i will get the numbers together and chase up. What do those gas-research mixes like?

Gas Research systems are kewl

But.....




For real grunt from LPG......



LPG INJECTION

why is that?

can you safely run leaner mixtures without pinging ?

LPG Injection works similar to fuel injection. The injectors are simply fitted to the inlet manifold ( drill hole & tap thread ) and hook up tp puter.

No power loss through the "mixer" or "Carby" setup on traditional LPG conversions

LPG injection is more ecconomical to run, although around an additional grand to fit, it provides more horsepower over a straight petrol setup !!

A mate has it fitted to his GQ and it farken flies on LPG compared to petrol.
The Converter is still fitted as perusual but there's no mixer as such, on his setup its damn near imposiable to see the LPG injectors as they are fitted on the bottom side of the inlet manifold. He gets around 35MPG on LPG and its a LWB GQ and thast usually with a decent load onboard too.

I would love to fit it but the $$$$ are tight ...................... as per ususal

Kingy

What bulltish.
The guys next door did their 1st gas vapour injection to a 3.5 litre Rodeo about 2 weeks ago. The power was within a couple of kilowatts of petrol and economy perhaps a couple of percent worse which is exactly what they were told to expect from the gas system manufacturer Parnell.
This is no way in this world that your mate will ever get 35 mpg on a petrol Patrol motor even if it's going down Everest with the engine on idle

If it's got massive tyres and it's all highway work where the engine is sitting at 1800rpm, then I can quite easily see him getting 8L/100 (35mpg).

It's not that unrealistic - my old car used to get that easy, and sierra's are better then that standard.

My sister's car gets 45mpg stock standard buzz box.

Tuned with the right gearing, you could get a patrol to do that - but it would accelerate so slow

For starters Mick ( the guy who owns the GQ I spoke of ) drives like he has "Miss Daisy" onboard.....
secoundly we live in a small country town so city mileages are something we dont worry about nor impact our "daily driving habits". For both of us its 2 minutes and we're doing 100kph out on the open road ( well 90 for Mick !! )
thirdly Mick spent a huge amount of time on the dyno and setting and resetting the puter and system to obtain optimum ecconomy...he has the gear to do this and the time & skills too.


Then there's Tony.... local fridgie who owns a toyota Crusier ( 96 model I think ) he drives like he IS Miss Daisy.....80kph is fast for Tony and thats on a good day ! He tows a 6x4 trailer everywhere with his work gera in it and he gets some amazing mileage figures from it ( 28mpg to 35mpg ) and I dont even belive he could return such figures but I've seen his log book and it adds up ( the yota is his work rig )

By and large its all about how you set up the system....either for ecconomy OR for power. I set my 350 up for power so I get shyte ecconomy, thats the trade off ya get..... I'd be lucky to get 11MPG from mine but it pulls like a freight train and can easilly top 200kph.

Both Tonys and Micks rigs throttles would never have seen the mat, where as mine has a large dent in the firewall and spends most of its life there.


I did a straight LPG setup to a Mitsubishi Sigma several years back, it was a 2.6 motor with a 5 spd box on std rubber for that model..... it regularly returns 45MPG to this day !, mind you its top sped is 110 kph not the 160+ it could achive prior to the conversion....but thats how the owner wanted it setup.

Build it for ecconomy and drive it for ecconomy and you'll get ecconomy.

Kingy

I'll stand by my original post. 35 miles per gallon = 56 kms per gallon divide by 4.55 to get kms per litre = 12.30 kms per litre.
There ain't no way a petrol/LPG Patrol will ever acheive those sorts of figures particularly as in your original post

its a LWB GQ and thast usually with a decent load onboard too.

So he's hauling around over 2.5 tonnes.
I've talked extensively with Mike next door at Auto Gas Connections about fuel economy on Patrols with LPG and he'll tell you straight out it can't be done and he's spent over $150,000 on the most sophisticated 4 wheel drive dyno you'll ever see plus over 20 years in the LPG business.
Sorry but I'm thinking along the lines of Kerrigan in "The Castle"
"Tell him he's dreaming"
Regards Andrew.

V8 Patrol..the injected LPG system. I this system only applicable to EFI engines. I have a Mav with carby and I am guessing that this is no go. I dont have a computer to start with unless the injected LPG system has an optional setup.


PS I am located on the Mornington Peninsula..any chance of seeing your mates rig or getting pix.

I'll catch up with Mick in around 10 days time .... ( we work opposite shifts ).
I'll get ALL the relevant info then .....
IE:
Where from .....
How much .....
What was involved...

& I might even get some pics ..... problem here is that there is stuff all to "see" as the injectors are UNDER the inlet manifold !


but We'll see

Kingy

hey road nazi you live on the mornington pen do ya me too

V8Patrol I am very interested in the info as well, I have a 92 GQ EFI on gas, but I only get around 14 mpg(4.77 km/ltr) on gas. I would be really happy to get more than 20 mpg. Especially since I have to pay 63 cents/ltr.

I have only had it for a month. (1st 4x4)

1/2 the Nation is keen to see how this miracle happens to...

poll on the GQ forum nobody with a gas/petrol got them figures, or close...

Yeah, I'm with you Bruce.

35 mpg divided by TB42 petrol/LPG
