I honestly thought it would be no higher then 9L/100km with a 4k... guess not :(

what kind of carbie?

 

 

I used to get about the same with a carb needing a rebuild.

 

Now with my 4k+ rebuilt 3k carb + extractors I usually get about 9L/100km

 

I'm running a 32/36 which was dyno tuned to the car less then 4 months ago. I should of also stated I have a company vehicle so I may tend to be a little happy on acceleration because I hate sitting behind traffic. Even when driving sensibly I would get around 10L/100km though.

 

On another note what fuel are people using? 91/95/98 octaine?

I found some old fuel economy figures from when I was running a 4k.

 

Car: ke15 with a 4k (270 deg cam, portwork, 9.85:1 CR) + 5 speed running a 28/36 dcd Weber.

 

At the time I was doing some delivery driving in around the suburbs south of Brisbane. I did 1302 km for 101 liters of fuel. 7.76 l/100km or 12.89 km/l. On the cruise it was better. Not bad for a thing that would easily outrun your average 6 cyl falcadore.

Wow felix that's pretty bloody good.

 

I run 98 octane, that's a must for me because the comp is high, I have been forced to run Caltex 95 this week and damn does it ping a lot.

second that i too have to run 98 too otherwise my corolla will ping its tits off.. I have twin 40 dellortos on my 4age and ill get only 350-(400 if I'm feeling lucky)km a tank but I'm in majour need of a tune. Once i get a tune it will be a different story though

does any one have any figures from a sr20det in a rolla?

about 80% what an sr20det would be in a s13.
