Fuel Mileage

[Karhu]

If you are only running 235 75 15 and you want to run a diesel in your tracker. No matter what diesel you pick you`ll have to use a numerically lower gear set. since you tracker comes with either 5:12 if standard or 4:62 is auto. You ll need to drop to 3:62. I belive the sammi third will work.
If you want to get away from re gearing you`ll need to run at least 31`s. That way you ll only need to use the 4:62 auto gears.

MPG will be amazing with the small tires.  I`m guessing 40 plus easy. If you get the pump tuned on the 1.9 with the K14 turbo. You ll get bigger # s then the 1.6 and the same fuel economy.

Now you got me interested......

So it's possible to swap the sammi r&p gears to sidekick/tracker? So the sammi's third will bolt right in?

Now that I am done tweaking the motor to see how many ways I can break something else, I still get about 30 MPG with Dunlop 30X9.5 mudrovers. I am running the 1.6 TD with fuel up boost up repairbills up wife yelling each time I break it and still love it.

I will be turning everything back down as close to stock as I can. I may even go back to stock diameter tires for the everyday driving. As far as off roading and crawling I am fooling myself if I ever think I could keep up with the Formula Toyota Cage buggies out here in the SO Cal Deserts. They average about $20k to build nice and go where the Sammi will never go. Locally going over the common trails with the wife without jumping off cliffs and rocks the 1.6TD will do great at 30 MPG close to stock settings. At first I had a lot more power than the stock motor and got close to 35-37 MPG on the trail or the road. I like that more than scaring the wife and blowing the motor.


Summary stock 1.6TD stock sammi 35-37
1.6TD max fuel flow 15-18 boost 30 MPG on 30 inch tires lots of black smoke on the hills and hard acceleration.

If your getting too much black smoke you can back the fuel off a little until it's still there, but just noticable. The black smoke is incomplete burned carbon.
I cranked my fuel up and had black smoke originally, and there was good power, but my mpg was down. I messed with the fuel until now I barely see the black smoke during the day, and my mpg is up. Power is still acceptable and it isn't as offensive to the guy following me on the trails. At night I still see the smoke in the cars headlights behind me, but it isn't thick like it was.

Sami axle gears are 3.73, was the 3.62 a typo? .1 makes a substantial difference on top end rpm.
ex...  I have a .865 5th at 3000 rpm I run 55ish.
With the early .765 5th at 3000 rpm I'd be at 62ish.
7 mph is substantial when it comes to mpg at the same rpm.

 I was thinking 4:62 when I typed 3:62, my bad.
Most sammi owners are looking for lower gear sets for their sammi when they go bigger tires and usually take the tracker 4:62 and put the 3rd into the sami housing (hybrid). Works fine.
Your case is just the opposite unless you run bigger tires (31s). That way you can just use Stock gears for a tracker. As for what motor, 1.9TD and 1.6TD are physically the same.
If you run the 1.9TD from an early 90 s VW you ll get teh perfect. motor for your use.

I think the 1.9 block is 1" taller than the 1.6.

[AcmeAdapters]

Yep, 5/8 inch taller block and the 1.9 adds a bit more with their intake. 1 inch would be a good number overall

Sammy R&P to Track / Kick Front = yes

Sammy R&P to Track / Kick Rear = no

2-dr 1.6L 16v 4wd 3spd auto Track / Kick  runs a 4.30:1 axle gear which is the lowest stock gear ratio I know of.

As for 1" of height extra... All depends on what year 1.9TD and what you get it out of.. Passats are diff then golfs. European are different again.
So many options. VW has seemingly no ryhme or reason for half of what they do.
