Fuel efficient?

after getting the torry back on the road, I am a little concerned with how much fuel im going through....
Im getting about 6-7km/Litre which is slightly more economical than a 2006 Hummer!!!!
its a red 202 with stage 3 Y/T, 4 Barrell 465, alloy gears, 31/70 cam and mostly standard bottom end with a 3.55.
I have noticed the throttle shaft on the carby is a bit loose and seems to let a bit of air in at high revs which would suck a bit more juice but not THAT much.
So what I want to know....
What is you're fuel economy like?
Let me know your setup and how many K's per litre you are getting and on which fuel.
Cheers all

6-7km/L ~14-17L/100km
Depending on your driving conditions, this sounds about right for your setup(low gearing, large carb etc), you dont mention what the 202 is installed in........which also has an effect on fuel consumption.

To answer your question, my 202 with mild cam, webber ADM carb and extractors used to get arould 10L/100Kms.. i was pretty happy with that! BUT... ( Here's the info that i think might help ya!)..
I took my car to a mechanic with a gas analyser.. He put a probe up the tailpipe and found heaps of unburnt fuel in the mixture.. so he went to town on teh carby re-tuning it for economy as that's what i needed at the time. I lost power but he brought the unburnt fuel down to <.5% and the economy was awesome! I definitely reccomend you go to someone with the skills to play with your carby and ignition setup and get them to gas-analyse your car while its running to get everything spot on!
Good luck!

23L/100km.
That is my average over the last 10 months or so. I write down odometer numbers every refill. Ive been meaning to get a tune for months to see if my consumption drops.

I think this is due to the fact that the setup is turbo and he seems to have a bloody heavy foot...23l/100km??? And thats with SU's!!! Holy Crap!!! You surely can't afford NOT to get a tune up....

Litre8 in turbo 6 guise (running 800 dble pumper Holley) used to get 23.5 mpg (12l/100km) on a trip.

Also, thats not with a super heavy foot. just averagely heavy. I drive it every day almost. I was trying to work out if buying a second car (very fuel efficient, work only) if the cost of rego and insurance of the second work car would work out cheaper than the fuel i would use in the torana going to work and back.

I personally wouldn't be driving anything larger than a mild Holden six on gas as a daily driver... something tells me you'd be blown away by the economy of some vehicles, Mike. And blown away by the lack of performance of the same vehicles hahaha
For the environment's sake, I'd always have my daily driver on LPG (so it's not as harmful) or Diesel (it's harmful, but there's ~30% less of it).
Petrol will be for my weekend cars, but that's just my view on life

I put $50.12 (40.11 L) in on monday, that ran on out Wednesday, put $25 or $30 in Wednesday of PULP, 1/8th of a tank left when I just got home now - that'll definately read zero next time I fire it up.
PULP definately seems to last way way waaaaaaay longer than ULP for me and car runs less like s#@$t, might have to start using it again more frequently.
I did quite a bit of driving this week however (more than usual).
So I'm probably using about $50-60 on average per week which I have confirmed has 60thou overbore and ported/polished heads. 450 Holley (Probably a bit small for it's application - might have been re-jetted, not sure).
Supposedly stroked by the guy I bought it from but not sure I believe that part going by the valves on the head, stock cam.
I'd say I'm doing about 300-350k's of city/suburbia driving to a full 55L - Definately put the boot down to halfway a few times per fill-up (I'm still addicted to making it growl ).
So that's 16-18L/100k's.
For city driving and my driving habits that's not too bad for a 308 I guess!

Mind you, the car hasn't had a full tune yet in its 2000k life so thats why its all up the creek . Dizzy getting re-curved next week then in for full dyno tune to get it operating correctly.
Peace,
