Dieselboy getting his goal with his heavy SUV!

Some foto's of my car drifting, I never knew that it does that so wel

The official numbers are in.
I came from a far end and getting a lot better now


Fuel use 2011: + 10l/100km + 23.5mpg
Fuel use 2012: + 8l/100km + 29.4mpg
Fuel use 2013: 6,9l/100km 34.1mpg
Fuel use 2014: 6,2l/100km 38mpg

Target 2015: + 6l/100km + 39.2mpg
Target 2016: + 5,9l/100km + 39.9mpg

In my garage you will find for 2013, 2014, 2015 and from 2013 until now a fuel log

smashing MPG! good job!

Looking for coroplast to make the belly smoother. So far no luck of finding it in my little european country...

How much effect has changing gearbox and differential oil to lower viscositie?

[oldtamiyaphile]

I think the general consensus is that you won't be able to detect a difference against background noise, but as you get into 6L territory, even tiny gains tend to be magnified.

Check your manual and see if they specify different oils for different climates. If they have a one oil fits all policy then going thinner would be a good idea.

At the moment I aim researching the idea of an engine oil pan heater, transmission oil pan heater, (and for winter times) a window defroster/cabin heater.

Specifications:
engine oil pan heater: 12V 100W 8,3A
transmission oil pan heater: 12V 100W 8,3A
cabin heater: 12V 200W 16,7A

These heaters are triggerd 15 minutes before departure, hopefully with an remote control, so i can chose if i need the defroster or not.

Total amp drawing: 33,3A (12V -> 400W)
@15minutes => 8,3Ah @ 12V

Thats not an massive amount of energy
So i was thinking of putting a battery in the trunk, power all those things from there so i dont empty my starting battery.

After the engine runs and the alt is charging the starting battery, the heaters change over to the alt.

Hopefully i can charge the battery in the trunk to.

But i got stuck on the charging times of battery's.
There are only 2 kinds of accu's that can be recharged in 30 minutes :O
Lipo's or lifepo4's!

Or aim i missing a battery?

Here in the states, I am used to seeing plug in heaters that plug into grid power. This would have the advantage of less added weight as you don’t need a battery, with the disadvantage of only being able to plug in when you have a plug.

One thing about using high end batteries like that is that you would probably need to use a DC-DC charge controller on them to ensure you didn’t shorten their lifespan. Many newer battery technologies are very sensitive to charging power quality. My suggestion if you wanted to use batteries would be to repurpose a battery from something else with similar power requirements an established charging setup, like an old laptop, cordless drill, RC Plane, etcetera.

Supercapacitors would be an option, but might not be practical.

The idea would be to use the same battery of the vehicle to provide power for those starting aids, just like a stock glowplug or grid-heater setup.

Yes. The first stage is to use a few heaters dirctly of the alternator. Only starts to heat a few seconds after enginge start up. If i see gains and warm up time can be even shorter if i use preheating the engine before start up. Then I will invest in a battery so it wont drain the starteraccu or shorten its life.

I orderd the first 120W oil pan heater. And a relais (30Amps).
This week was nice hot. But just not to hot so i didnt need to remove the upper grill blok.

I tooked some temperature measurements.
Fuel filter: 45°C
Metal fuel line direcly before injector: 60°C
(Had no time to measure the temp of the fuel rail, beacuse then i needed to remove the plastic engine cover)
Engine oil pan: 65°C
Gearbox oil pan: 50°C

Next week, I work at night, so comming home in colder temperatues. I go measure again, and probably would see the biggest different of temperature at the gearbox.

With this data, I can choose where to place oil pan heaters to help heat up the oil.
