Basic :
Increase tires pressure from 35 (2,4) to 44 (3.0) PSI (Bar)
Idle speed down to 650 rpm starting from 850 rpm (tolerated by my engine due to low internal aerodynamic cylinder to cylinder dispersion
Expected FE benefits (simulation) : -10% (0,5 l/100 km) for free (tuning only). Forecasted Application date 07/2014
1st Step :
Change tires dimension from Michelin 135/70R13 to Toyo NanoEnergy 3 155/80R13
Expected FE benefits (simulation) : -10% (0.45 l/100 km) - Cost average : 160 € (4 tires)
Impact on Gear Ratio 1000rpm speed (km/h)
I : 8,22 (previous 7.38)
II : 15.52 (previous 13.94)
III : 24.87 (previous 22.33)
IV : 34.5 (previous 30.98)
Forecasted Application date 10/2014
2nd Step :
Change GearBox Ratio from MA4 to MA5/O (from Peugeot 208 DV4C HDI stock model) - Expected FE benefits (simulation) : -10% (0.4 l/100 km) - Cost average : 150 € (DIY)
Impact on Gear Ratio 1000rpm speed (km/h)
I : 8.62 (previous 8,22)
II : 16.28 (previous 15.52)
III : 25.13 (previous 24.87)
IV : 34.51 (previous 34.5)
V : 43.27
Forecasted Application date 02/2015
3rd step :
Lean Burn operation modifying Weber Carburator 32ISBH16 with Panda Fire 750cc carburator inner parts. Spark plugs modification from standard ones to double thin Iridium to avoid knocking
- Expected FE benefits (simulation) : -15 % (0,55 l/100 km) -Cost average : 50 € (DIY)
Forecasted Application date 04/2015
4th step : Aero drag reduction :
Under bonnet cover
right miror suppress
Expected FE benefits (simulation) : -5% (0,15l/100 km) -Cost average : 20 € (DIY)
Forecasted Application date 06/2015
Total targeted Fuel consumption : 3 l/100 km (starting from 4,9 l/100 km)
Additional mods in case of target non reached:
Oil change from 15w40 to 0w20 (I'm fear durability concerns with this mods)
Gearbox oil change with low friction one
Increase Tires pressure up to 50 PSI
