Vw pickup MAX mpg build!

If you can find them and they are not stupid expensive, go for it.
Wheel bearing if properly setup really don't create much friction to start with. Plus wheel bearings are operated at relatively low speed, usually turning less than 900rpms at 60mph. But that all depends on tire size and actual speed.

I prolly won't do it then, I read all the propaganda from the ceramic companies lol and I want to take it to the MAX! so I was a little more easily influenced by some of there bs, but this is why I am running this by the ecomodder community to point out some of the holes I can't see my self . Thanks for the knowledge

Tires with less rolling resistance most likely have more benefit then those bearings

the Mk2 big bumper covers from around 1991-92 can be morphed onto a Mk1. I've seen it done. Might be worth it to do a little google searching on that and project sipster that has been mentioned. Take what they did, make a aero bed, low RR tires, moon hub caps and I bet you could beat them.

Oil, use Shell rotella T6 synthetic 5W40. If you go too thin, bad things happen to VW motors. You might be able to use Redline MTL in the trans to cut down on lube drag there.

IDI motors do not respond well to propane injection from what I hear.

Injectors: A good set of balanced injectors with proper new heat shields is probably the best way to go.If you are already talking with or going to go with Giles, he can sort that all out. I've had 3 injection pumps done by Giles. I wonder if he still posts the video he did with my 1.6 TD pump? I was the first in E TN with a Giles pump. After the local shops drove my cars, they now send their pumps they want done right to him. It costs some $$$$ but they are spot on, install it and forget it. He is best one to discuss and set up your needs for fuel economy with the injection system.

You do know about the VW GTD forum? VWDiesel.net The IDI, TDI, and mTDI source.

Look at the techtonics tuning downpipe and exhaust. Uses the stock 2 hole cast iron manifold with a decent sized piping. Not too big to ruin exhaust velocity hurting torque, but a bit better flow to not choke the motor. most 4 into 1 or try Y headers for VW are aimed at top end HP. you want torque and efficiency.

What exact transmission code do you have? You have tons of gear ratios to choose from. How high would you like to gear it? Trans from 1975 to 1998 and beyond will bolt into the Mk1. The later you go, the harder to get the linkage and clutch sorted out but it can be done.

There is almost too much info to dump onto you all in one post. I wish you luck in the project. I have a TDi into a 1981 Scirocco S project that is floundering from too many other projects.

Ted thanks for the detailed information, I have lots of friends in Knox, I went to Nashville auto diesel college, you live in a beautiful state. But as far has 4-2-1 headers go I have seen some that are 1.25 in diameter but I have not found one with very good build quality yet. I will find out what my trans code is today and post it. I still need to go over some of the information you posted and check out that forum .

That is what everyone says about IDI motors and propane.
Mine ran fine on propane, but I was only trying to run about 10,000 to 12,000 BTU/hr (not really that much) on a 389 cubic inch diesel.
Don't worry about finding small headers, that is a gas motor thing. The diesel will do fine on 1.625 or 1.75 inch headers.
Big exhaust doesn't hurt fuel milage on a diesel engine like it does on a gas motor.
The more air you can get in and out of them the better. Where with a gas engine, the more air that goes into it, you need the same proportional amount of fuel to go in there too. Diesels only burn the fuel they need, stuff all the air you want into them, it will only further increase power and fuel mileage.

You should get a turbocharger. On my current engine when I turbo charged it I picked up 2 to 2.5mpg when I added the second turbo charger it increased fuel economy form 0 to 0.5mpg. I do not believe adding the second turbo and intercooler hurt fuel mileage.
Now that doesn't sound like much. But I was only getting 17 to 19 mpg with out the turbo.

I would recommend that you GOOGLE ultra-low-drag bearings/tribology.
There are some fine articles about micro-finishing and synthetic lubes vs efficiency-economy.
You may decide that the ceramic bearings would provide savings lost in the signal-to-noise ratio of testing.Only lab testing could convince an onlooker that a savings could be realized.

I can not find online where my transmission code is located and I don't see it in my Bentley services manual there is a good layer of grime all over the transmission so I can't find it with a flash light if someone could tell me the location I would be very grateful

Found it it's FF

I have a gift of information to those that read this thread on the alternator delete one negative is the aero penalty when putting conventional solar panels on the roof ,, well now they have boat solar panels that are just a few mm thick and are strong enough to walk on. A 50 watt 20 amp panel is 150 , number to is the heavy deep cycle batteries that put off dangerous gasses and there cost is high, the cell phone towers have lithium ion batteries get replaced every two year new they are over 700 bucks but you can find them used from 15-100 bucks they are 1/3 the size and weight of a deep cycle and you guys know other the other benefits of lithium
