I'd guess the ethanol didn't hurt Van's mileage as much as his heavy foot did!!!!
From what I recall......Devek quoted at 200mph the white car got 9mpg.....George got 5.6mpg for the 90 miles he averaged 180mph and hit 219.....on race fuel I think?
My racer at its lowly 265whp burned around 10 gallons per hour which ends up around 9mpg...I think the current GT3 racers at 500+whp burn 20 gallons per hour....the lemons racer at its impressive 215whp was around 7.5 gallons per hour..or an impressive 11.5mpg

Regarding fuel consumption...going over my records for the trip I realized that when I had to use fuel with ethanol ( 10%) my mileage dropped a bit. Not sure if Nate or Jim experienced the same thing. I didn't want to use fuel with ethanol but sometimes when it's all you can get ...
It's ****ty gas and it pollutes more than the dino fuel. BTW I don't drive thinking of what my mileage will be. On my way home I was driving as hard as I could from station to station. This is big freakin' country.

Vans car is a dream on wheels!
I would like to build a car like the 718 GT4 in a 928 S shell. State of the art mechanics in a moosgrün body with patina.
The car should be historical correct, so I can drive with H license plate. Modification should be invisible for TÜV.
Most Germans don‘t like visible success, so I‘m the crazy farmer with the „housewife Porsches“. So I must drive this 924 thing for the rest of my life!
In my village live 3.300 citizens, it‘s countryside with open roads.

Karsten, it looks like you are not too fond of TüV?

I use Google translation for the rules for H license plates
If you have the H license plate you pay 191 € taxes per year, without for an S without cats 1000 € more.
Prerequisite for H license plates: the original condition
For example, a classic car may only have paint finishes that were available in its year of manufacture. Likewise, a defective motor may only be replaced with a motor of the same series. Only add-on parts that were common in the first 10 years after initial registration are permitted. Major conversions must be at least 30 years old. The H license plate is also not assigned if there is severe rust or accident damage such as large dents. Another reason for rejection: built-in spare parts that are not the same as the originals.
The vehicle owner must have the original condition confirmed in the form of a classic car appraisal by a recognized expert - such as TÜV or DEKRA. The Vehicle Registration Ordinance only vaguely specifies which structural requirements a classic car must meet for registration with an H license plate. The appraiser therefore always has a certain scope for evaluation.
In any case, the classic car must be roadworthy. It must pass the main inspection "taking into account the technology of the time without any recognizable defects".
Environmental zones may also be entered without a catalytic converter and without a green sticker. Because you can retrofit a cat, but you don't have to do it because of the originality.

Karsten, it is typically German to have complicated rules for many things.
Here in Sweden we have no H-license plates (H=historical) but for vehicles model year 1989 or older there is no requirement for a catalytic converter, which I think is very good. Once the vehicle has reached the age of thirty years, it becomes tax-exempt and inspection is changed to every two years (normally annually).
When the vehicle reaches an age of fifty years, the inspection requirement disappears and then it will be possible to modify the vehicle as much as you desire.
Old rare cars like the 928 are usually unknown to younger inspection technicians, which means that they do not see or overlook many modifications made to the vehicle.

It sounds like the perfect 928, for "H" classification, would be an '84 to '86 Euro S, with one of my 5.8 liter combinations inside of the original engine block. Stock externals, with all the "good stuff" neatly installed inside. Update the fuel injection to '87on (visually the same) to be able to have knock sensors and simple tuning.
400 hp, in an early car, is almost more fun than a human should be allowed to have!

My 87 does'nt seem to have the oil consumption issues. It is our long didstance trip car and I recently returned from a quick 3 day 900 round trip from Houston to OKla. City. Took a couple of side road detours, varying speeds up to 110. My last oild change was 10 months, 4100 miles ago and my level is just barely below the full mark. I wonder if my long time use of Marvel mystery oil in both fuel and oil ( 1.3 quarts per oil change, 2 oz avg fuel fill up) I also have GB's fuel lines, PK tensioner, Black Sea torq tube, hardned ECU, and do average 19-21 mpg depending on speed, temperature and driving conditions.
I have been using MMO in all 6 of my cars and vintage Goldwings since ownership. Comments?

I have 4 good heads and a barn full of other stuff.
We should talk about whole process via pm. I have good connections if you need something rare 928 related.
