Project: VW Polo 86C with under 3l/100km

[Jack-Lee]

Hi,

the old engine was a "AAV" with monomotronic.
The new one get a sequential Multipoint injection, controlled with a "Trijekt".
Here the engine tuning-thread : http://ecomodder.com/forum/showthrea...1-a-26353.html


This red Polo is my second. My first had a AAU Engine. No changes, full stock.
Best result -> 3,8l/100km (from tank full to empty)
Best result with the "new" one -> 3,3l/100km over 1250km (Highway)

No chance with this old diesel.

And now the reworked version

Without a true-length X-ray look in the side elevation view,it appears that the diffuser angle might be a bit steep.
The lowest drag versions are no more that 2.5-degrees,and the higher drag version is limited to 4-degrees.
I constructed a 'fast' diffuser for Bonneville,based upon a Mustang GT of the 1980s,only to discover that it produced unwanted drag,which was resolved in the short term with cardboard and duct tape.
Closing the opening down,and relaxing the up-swept angle allowed a speed record and mileage above 60 mpg from this single modification.

Hi,

the angle of the difusor on the picture are 14°. To much :/
The new angle (read in "Hucho") about 5°, but i test 2,5° on monday.
Thx

That's a pretty impressive result for a spark-ignited engine
