sum thing to think about

I have a weber conversion and pace setter header i went down to Longview WA. today from Marysville.
I had filled up in Marysville just befor the trip then drove all the way down & back on one tank 336 miles on 12 gallons thats 28 mph what do u get?

friggin fantastic..lol

wow awesome

thats great wish i got that kind of mpg

ive done the same with my oem carb. sometimes have even hit 30!
how fast were you going and what size rims and tires? all that matters as well. mine was rolling 14s with 185/60 rubber, running at 70 on the speedo.

So your tires were undersized,doing more revolutions per minute,therefore making your milage higher.

im completely stock, 93 so its EFI. i pretty much get 30mpg

that's pretty respectable. Carbed ones aren't so great.

yeah i try to keep it under 70mph usually around 65mph, i find if you over that the milage really starts to drop. but 55mph get the best mileage.

I used to do LOTS of highway driving with mine,usually around 100-120kmh. Had to take the 400 to work every day. Mileage wasn't that great. usually 370-420km.
