It's ... not great. I try not to even calculate it, other than smiles per mile. I think when I did do it, it was around 22mpg. I do have a dragging front brake, which doesn't help. Once I fix that I would imagine it would be around 25.

Anyway, small update:

Welcome to air-cooled world. Remember: antifreeze is poisonous to puppies and kittens. Consider this:

Hot VWs magazine took a Beetle from 28 to 39.9mpg with their Mileage Motor build.

It was based on work by Jon Karcey, described in a seven page The Samba thread here: https://www.thesamba.com/vw/forum/vi...er=asc&start=0



The work was carried forward by Jake Raby into the Type IV (912) world: Raby Aircooled Technology – The Most Advanced Aircooled Engines for Vintage VW and Porsche cars.

The Hot VWs series was at CB Performance but now it 404s: https://www.thesamba.com/vw/forum/viewtopic.php?t=97269. Maybe try Internet Archive.

TLDR; square bore/stroke, high reciprocating mass, Hall effect ignition, air dam, Jet-a-Vator, low-friction lubricants, 145s on the front, etc, & etc.

If you don't want to go Type IV, then the Emorys cut flat sixes down into DOHC flat fours. https://www.emorymotorsports.com/the-engine/



Best mileage I ever got with my 1971 Superbeetle was 38mpg over 1300 miles, running through Eastern Oregon in the middle of the night at 45mph, on the way to Bonneville.

Cool project. I hope your user name reflects your bank account.

I started a similar project about 20 years ago on a 1972 914. I was in a front end collision and decided to use the insurance money to to the build I wanted. What I found out in that the Porsche logo adds at least a zero to everything. I started a spreadsheet, priced out what I wanted to do - saw that it was $15,000 - and sold the car.

I kinda wish I had that car today - especially now that they went from black sheep of the Porsche family to red hot appreciation. It is crazy to see them selling for $20 - $30,000 now.

Nope, student loans keep me pretty freakin' poor until I"m about ready to retire. Hence why I am doing everything I can myself.

Updates: This video is honestly more of a comedy; the fact is the fan SHOULD have slipped off the alternator....but it refused to do so.

7:22 ... ... lots of patience went into that effort. 4 days?

+1 for saving and restoring the original hardware. I like the salvage approach most.

Small update: Drilled out my engine bar to make an RSR style engine bar... rennline sells these for $250. I spent... $20 on some hole saws or so.



Pretty simple stuff, using the paper template is my only protip on this one.

Modest weight reduction there. How much?

I removed 8 ounces from the engine bar, and 3 ounces from the intake runners. :P

Alright... the most expensive part of my project so far, because i farmed it out: A transmission rebuild. This trans is magnesium case, so a weight savings of 30lbs over the aluminum versions (super rare and desirable!).

I go over the basics of a 915 transaxle, a cross section showing how they work, and some of the upgrades I sprung for during the rebuild.
