I was digging through my collection of VW material and came across this. Figured I would share. The second article reminds me of a recent TV show where they took an old Rabbit and tried to get better mileage by dropping in a TDI. Enjoy.
I'm a bit

there is not more change in the 1/4 times.
It does not appear that they made any boost-dependent fueling compensation, so your increase in power will be limited. They also talk about 7-9 pounds of boost pressure; that's under stock 1.6TD levels.
Ahhhhh....this was just about the time I bought my first Wabbit.
How I long for simplier times.
Now, this mpg figure was calculated on their local loop and NOT on the trip....right?

?
Because I struggle to buy the mileage figure they quoted (as far as real world traveling) (especially considering the trip west of Denver).
However, the highest mileage I ever did (consistently) achieve was in that first '78 1500 I had.
The car died when my wife ran it into a concrete wall (yes, I DID divorace her!!!!!).
So was the 10 gallon aux fuel tank an option? And the digital clock on the shifter?
1200 bucks for the BAE turbo kit!!!!!
