Interesting stuff. I like hearing about it, thanks.

My next mods on this van will be in the performance dept. and both are ones I have some experience w in this van as well as on other platforms—not that this vans a slouch in anyway! Future perf mods: 11mm injection pump redux and propane fumigation.
this gets into the tech weeds right away so skip the rest of this message if need be. My plan is to put the 11mm injection pump back on there that I pulled off this past winter at a timing belt service interval and replaced w the stock 10mm one, as a test to see if my mpgs would get a decent bump—they did not, no gains noticeable (stock AHU IP has a 10mm plunger; but the decrease in power was noticeable! It had an 11mm IP from a a later tdi eng the ALH w A/T ?modded to fit an AHU eng on there for the last 80k miles and I swapped?it out this past winter for the mpg test.
The other mod I’ve got on the horizon is a LPG fumigation mod and something I’ve played around with on a T3 Vanagon also w a MK3 Tdi eng conversion some years ago (decades now:). That was a nice and relatively easy mod that gave a noticeable power bump as well as a slight (2-3mpg) bump, and I like to think a cleaner burn of the diesel fuel—smelled cleaner anyhow. It involves—brace yourselves—plumbing a line from the propane take to the air intake and introducing lpg into the combustion chamber. “Fumigating” a combustible had lpg into the motor via the intake air. Not something for the faint of heart. Lots more info online about this so do your research for more info. I only know diesels and obviously there are very few diesel EVs in NA. Anyhow I’ll keep the list posted on these mods and remember YMMV ;-)
I’m realizing I just hijacked my my own thread—sorry! ?
