Outer Limits 4x4 Board

for the comp guys mainly.

how does running straight gas on a TB42 turbo go for the day or weekend? as most comps are away from gas carrying petrol stations. how is the consumption through the event. i dont care about economy just tossing up between converting to EFI turbo or throwing on straight gas and a 150 litre tank and get rid of fuel. are there any reliablility issues to contend with during whinch events with all (Dr. frink voice on)the water and mud and hivon claven.(Dr. Frink voice off)

cheers

Most gas cars ive seen at the comps all run twin tanks..

So if it were me id run a 110L usable or ther abouts underneith and a 75L usable in the backso it doesnt take up as much room.

That should be enough for the weekend id say, but some cars are different to others. May mean a trailer ride in..

150 litres is heaps. I had 4.2 non turbo carbie and 88 usable litres. Use to drive from kilcoy to cruiser, race and then drive back to kilcoy and had only used 60l of gas.

Ludacris

fair enough. might go that way then, i know a turbo may double those figures luda but i will be trailering to comps i think. so it should be all sweet. thanx guys

I have 160 usable litres in mine and that will get me approx 280 to 300 klms in 4 wheel and giving it heaps . but on the highway I can get 500 klms . cheers shane...............

I had a 100L usable LPG on my Dual Fuel Maverick. i got 450-500K's around town and between 700-800 on the freeway.

If you go straight Gas u can get better figures.

if your going straight gas, either get a gas research carby or get an EFI manifold and throttle body and do it that way.

ive got twin tanks, but long distance travel is always a bit of a worry.
I'm thinking of getting spare gas tanks like off the forklifts and changing over tanks, not sure how it will work, but looking into it. There only bout 60lt but could be enough to keep you going.
Thats the only problem with gas, otherwise its great, dosnt cut out on steep angles, which is great. After owning a carby model before hand.

you got a gq now chunder?

Birdys used to be straight gas turbo. Rumour was the only reason he went back to petrol, was range etc for the OBC.

yeah GQ is just easier for the stuff i wanna do jump i know about the gas research setup etc. just after info if it would make a weekend of xtreme winch etc. without having to return to town to fill up.

thanks guys

appreciated.

I got turbo tb42 and i filled up last night and i use 33L per 100k's at this stage but i have been driving it fairly hard

Rick..

I only got 90L useable and i'm worried how i'm going to go anywere as my range would be 270kms

Anyone got sources or sites or anything on those forklift bottle as u can fit one under drivers side and then run another 60L right in the back and then u would be fine for longer trips !

Cheers

Rick..


Maybe everyone needs to put there heads together and try find a source for Forklift Bottles on the cheaper side not brand new ones becuase that might be the key to keep fuel up these thirsty animals..

That's sounds about right ..

When i had my car on dual fuel and it was tunned and all new plugs and everything in that area got 350kms to 90L gas..

Now i get 270kms to tank with the turbo..

Rick.

tis ok mate. u were just about building a patrol with a yota shell before anyways, tis the same reason i sold the bundy.

My petrol turbo 6 gets about 400k's to 100 ltrs which i thought was pretty good. Why go gas if you already got efi If you are going to do comps i think the $10 youll save on fuel would be the least of your worries

Just read your post properly Well if you are not worried about consumption. Go efi

efi engines are getting hard to come by now. and expensive aswell so thats why im leaning towards gas.

The efi heads are a lot better. Not so much flow wise but they dont crack as easy as the carby ones. Apparently they changed the casting

EFI heads also have a very very slight increase in compression. the Carby has 8.3:1 and the EFI had 8.5:1.

As for my patrol getting 450-500 around town and 700-800 on freeway i don't really know how i got it. i had a Sprint gas setup, it had a rather large LPG converter that apparently was more designed for big V8's, ran it pretty low on the gas cause a 4.2L doesn't pull all that much into the engine.

I also had a bit of head work done when it cracked, had new Gas valves installed, all hardened for use with straight gas systems. Added to that i had a Crane Cam Electronic ignition system installed to the dizzy, which gave me alot cleaner spark. Lastly i got extractors and a 2.5" straight though exhaust system.

I now have a Diesel and looking at turboing that baby.
