Congrats Dad!!!! Hhahaha bet you didnt know I had a user name on here did ya??? I didnt either till I clicked on your link and I was signed in hahaha. The car looks awesome!!! and WOW I cant believe 74 mpgs!!!!! Maybe I can take it for a little cruise on memorial day??? I hope some one posts a link to that vid I really want to see that
i just want to point out that the 74mpg is not realistic to normal driving because of it just being one drive for an hour not 2 weeks worth of everyday driving sitting in traffic (not that i'm saying there wasn't any). but i once took my rabbit auto diesel and did the same thing, i filled up then drove for an hour and filled up again at the same pump, and i think i got like 60-65 mpg. not that what you have done is nothing, because i am certainly a fan of anything with a vw diesel in it, especially a 356.

This is a competition, and everybody was driving in extreme conservation mode, that is using "driving with load", and "pulse and glide" techniques. In "dwl" you try to accelerate slowly and conserve momentum at all times, you allow speed to fall on upgades and coast the downgrades. That's the plan I use, along with watching my EGT as an indication of how much work the engine doing. In "pulse and glide", the driver continually accelerates slowly from a chosen minimum speed (say 45mph) to a chosen maximum (say 60), and then coasts back to minimum. Repeat ad nauseum -- Not the most fun type of driving maybe, but challenging and rewarding. The accuracy of the filling technique is another factor of course. This event uses the "first click fill" method -- that is you fill at a given pump at a given station, you run the course and return to the same pump. With the car in the same position, you fill again -- doing everything (nozzle position, amount of "squeeze", etc) the same, stopping again at the "first click" of the pump. I think that's not the most accurate way of doing this, especially with a relatively short course of only 80 miles. I'm working now on a funnel/float gauge that I hope will give more accurate and repeatable results, we'll see --
Great project. thanks for the engine pics,.. the engine doesn't have much lean to it.Is there a kit for matching our engine up to that trany?
I remembered this when I saw your VNT controller. It inspired parts of mine.Can't remember if your vanes are closed at idle,..encoraging the turbo whine?My VNT15 is loud at idle, when the vanes are open and gasses go around the impeller. Pretty loud without a muffler?
I was not aware of certain tactics on achieving such high mileage. All I did was the speed limit (at most 62 mph), coasted when I could and was very easy on acceleration. Unlike your trip, I was stuck in rush hour traffic quite a few times. Not using the 'one click' method, for I prefer filling up my tank to the lip of the filler neck (which can take a bit of time),
I averaged my 89 1.6 NA at 55.9 mpg. I also got a lot of the famous NY 'one fingered waves' and I was in the right lane.
74 mpg is awesome. Again, congratulations.Stay safe, stay well. Jimmy.
