ummm no a 86+ and most 85's 22r and 22re block are 100% the same. You are thinking of the diffeence between a pre 85 block and post 85 22r/22re block.

After I put 32's on I don't even bother with the math to find my mileage

it's too depressing lol

 

Oh thats right.

 

I got 18 mpg out of mine the other day hauling 800# of rock (60 mph on interstate)

 

1985 22R with weber carb
31 inch all terrains
stock height, no gearing
I recalibrated the carb the other day and on a 6 hour round trip (80% hwy) and got 22 mpg with camping gear in the back.

 

Ya, thats what I like about the weber carbs, easy to calibrate. What jet sizes are you using?

 

1990 Pickup 4x2 Base

22R, 4 speed, Weber 32/36

I got 26MPG the other day on a road trip.. mostly highway driving around 60-70MPH.

 

I posted earlier - with my weber carb 32/36 I got 22.5 on a road trip last weekend. Stock gears, 31's, 22R. I know a little bit about these carbs from online research. I calibrated it based on directions from the web and I'm stoked to get that gas mileage with 31's. I plan on 32 or 33 inch tires and gearing it with 4.88's...I'm sure I'll keep similar gas mileage, but have a better, more capable rig.

 

UPDATE:

'93 3.0 X-cab, with a K&N CAI and AEM filter, 5spd, 80% highway @ 60mph and shifting on the street @ 1,750rpm got me to 17.7mpg.

Just removed my 2.5" Magnaflow exhaust from the cat-back, and installed all new 2.5" piping with an Aero Turbine AT-2525 muffler. Sounds much better, and I will post my mileage increase at the next fill-up.

 

1985YOTA4x4, What particular jet sizes are you using? I'd be interested in comparing with mine and maybe get some idea's.

 

1994 4runner 3.0l auto with 225/75's 205k 60% highway 40% city I got 22mpg before the head gasket blew and I haven't drove it since i blew

 

Another UPDATE:

So, My freeway mileage has increased significantly. Previous 60mph mileage was a true 16mpg. Now I'm @ 20mpg at 65mph. The only thing I have changed was my muffler. I'm now using an Aero Turbine 2525 instead of a Magnaflow 10416.

Mods to the truck are in my sig, but I've also turned the MVAF cog 2 clicks lean before the muffler change and saw a 1.5 mpg increase on the street and 2 mpg on the highway before the muffler change.

 

Don't forget guys, that half of you have ZERO aerodynamics due to modifying or removing your front bumpers, or have aftermarket tube bumpers. I mean, our trucks ARE shaped like bricks already, but this bumper effect is probably hurting our gas mileage even more.

Just a thought.

 

1997 4runner 4wd 5spd. 285 75 16 pro comp xterrains. 488 gears 3.4 supercharged 2.2pulley
11.5-11.6 no matter how I drive that's 60/40. City/highway I think I got 12 on the highway last week nd going to temecula oh yea 91 only lol

 

Awesome info, thanks!

Can you elaborate on "all new piping" in your original post?

How's it sound? I found this, but think his Jeep has more sound deadening than my 4Runner does.

Doesn't sound that good with the camera at the back of the truck, but sounds reasonable inside?

Whatever is on mine now is annoying on a trip from SoCal to Moab and makes talking to the person next to you difficult on short trips. It has to go.

 

And a valid thought at that. I have the stock bumper, plus 70#'s of custom bumper construction. But agreed, our rigs aren't the most aerodynamic things on the road these days.

 

Just need to take some notes from this guy lol. It says he gained 28% on his highway gas mileage with some body mods

Umm, yea...
