Hi all, I did a quick search but couldn't find much on fuel economy so I thought I'd post this up.
I've got an R34 GTT auto with a recently installed Hypergear ATR43SS2 and supporting mods (full list here), currently running 257rwkw.
I always keep track of my fuel expenses and I measure consumpsion by filling up fully every time and noting down the odo reading. Here's an overview:
Completely stock 150rwkw, overall average of 12.2 litres/100km over 8,000 kms
Stock turbo with upped boost and Nistune with supporting mods 199rwkw, overall average of 11.9 litres/100km over 18,000kms
I've only filled up the car the three times since having the Hypergear installed, however the average consumption is currently sitting at 16.4 litres/100km. Granted it's been a lot of city driving but it's still a pretty silly figure.
What kind of economy (litres/100km) are you guys getting out of your 250rwkw+ setups?
