fuel economy from 2052cc with twin 44s

Post by ernie » Fri Nov 14, 2014 5:44 pm

Hi all,

interested in a 2052cc engine fitted with twin 44 carbs for my bus.

I've got a DC gearbox code (type 3 I think), so think the gearing would be ok.

What sort of mpg do you think I would be likely to get out of this, say around town and also cruising at about 70?

Just wondered if the carbs were a bit big to get any kind of fuel consumption.

thanks

around time…and 70 both equal low MPG figures…..sit at 55 and it'll be reasonably acceptable

but yeah…70 in a brick is gonna be low 20's I reckon

Worse probably. Our 1915 in the bug gulps fuel down. My 911 is way more frugal. 8O

The 1915 in the '57 with Devon interior returns 28+mpg fully loaded and cruising at a genuine 65-70mph. Don't know what the g/box but prob got a 3.88 diff. I set it up on 36DRLA Dells with 28mm venturis and jetted accordingly.
I think your bug can't be set up right if you're getting such low mpg....the fact that the 911 is better kinda supports that fact.

Jen's 2110cc used to give low 20's when on carb's and she has a very digital driving style... ;-)

EFI has made that high 20's.

Cruising in my 1914cc does 30-35, less obviously when pushing it more.

It was set up on a rolling road by a porsche tuning expert, albeit a number of years ago now...

Jim - what sort of AFR can the engine tolerate at 70mph cruise? I've completely forgotten what mine is set to but wondered whether it needed overfuelling for cooling or acceptable ignition.
