Yes. I aim fully buzzy with aerodinamic mods. But most mods are not allowed on the road where i live. So need to be careful with the things i do.

Something that realy works is changing gear ratio's.
I run 2350rpm at 100km/h.
With is high for a 2l turbo diesel.

I was planning on changing gear ratios.
Placing the 5th gear where the 4th gear is. And then let someone make a new 2end, 3th and 5th gear.

The only problem is that the person who i contacted can only make straith cut gears.
Those make that wind you hear in rally and race cars. But is this also this loud in a normal car? In a diesel that does not run 7000rpm or higher?

I do run sometimes 3500rpm or 4000rpm... On the german autobahn! But with a higher 5th gear. Those rpms are going to be lower

Price: 1100 a 1200 euro.

Gain in milage: 4 to 20% (wiki reported)
so lets say a 8% increase.
With prices now and a bump in the future: 150 000 a 200 000km
I realy think the gain can be bigger then this. My highway consumption is higher at 100km/h then when i drive the backroads at 70km/h ( 1650rpm). Even 50km/h (1150rpm) i drive in biggest gear.

If i gain 12%: 100 000 a 150 000km payback

The car has 120 000km on it.
I drive 25 000 to 30 000km a year.
I plan to drive it until 300 000km.
So another big 6 years

I should do this. But i dont know if the sound is to loud for me or not...
Lucky i may drive with the car of his sun. A big jeep with has a strait cut final gear change for lower consumption.

I keep you updated!
