Club Member's Fuel Economy Thread
« on: 20 February, 2013, 09:19:56 PM »
As much as making power is fun, in a weird way I find trying to get the best fuel economy satisfying too. There doesn't seem to be a thread for this so I thought I might start one.

Might as well follow a template of some sort:

Chassis: p11 wagon
Engine: sr20ve
Transmission: RS5F32V FM41
Tyre Pressure: 38/38
Performance/Economy mods:  nil yet
Driving Style: Economical, occasional blat, sit at/above speed limit
Urban Fuel (L/100km) 9.18L/100km - pre-daughterboard Manual
Highway Fuel (L/100km)  CVT = 8L/100km. Pre-daughterboard manual = 8.7L/100km. Post Daughterboard manual = 6.24L/100km (careful driving)

If you have actual figures (not like $50 lasts me a week type thing - thats useless) then please post up!

Well I never record mine, but with a rich tune and stop start small trips around town I don't get much more than 500km out of tank before the petrol light comes on.

Open road is waaayyyy better.

Chassis: P11 Autech 4WD Wagon
Engine: SR20DE
Transmission: Manual
Tyre Pressure: 38/38
Performance/Economy mods:  High flow panel filter
Driving Style: Open road cruise
Urban Fuel (L/100km) Round 10km/L (best (unmeasured))
Highway Fuel (L/100km) 7.81L/100km (12.87km/L)

This test was when i first brought car i drove it from Porirua (wellington) to Mercer (south of Auckland) between full ups.
Since fitted a SR20VE head but haven't done any testing as im to poor to fill car to top then refill after test to get exact usage (only way to actually test your economy).  Hoping to crack 13.5km/L once tuned.

Chassis: 2000 Y11 Wingroad ZV
Engine: SR20VE
Transmission: Hyper CVT
Tyre Pressure: 38/38
Performance/Economy mods:  Nothing
Driving Style: Open road cruise
Urban Fuel (L/100km)
Highway Fuel (L/100km) 7.84L/100km (12.75km/L)

Open road test done only.  I feel this car with the Hyper CVT could be made very very economical as it sits at 2200rpm @100km/h. 
If i wasn't selling car to buy a house id fit SR16VE cams and tune it.  (im sure it can be tuned while keeping the CVT) id expect round 14-15km/L from this after thats been done.

Updated, got open road down to 6.24L/100km. Definitely more in it as that was cruising fast. Being a grandad would save maybe 5-10%

Just thought id add that we should put wheel sizes / tyre profile
Smaller wheels/tyres will show higher speeds, and higher mileage and vice versa for bigger wheels/tyres
