I'm wanting to squeeze every ounce of gas mileage out of my model A. would replacing the muffler with a straight pipe help?
Short answer: Maybe. Long answer: Maybe not. Sometimes exhaust back pressure can increase engine efficiency in certain rpm ranges.
Tyrone: I'm guessing, and that's all it is is a guess, that the result (if any) would be so minumally small thay you couldn't tell. Snyder's does sell what they call a high performance muffler with less baffeling & back pressure but who knows? Like Tom says some back pressure might be necessary.
Once it's warmed up how far are leaning the mixture rod adjust??Bud.
You will get your best mileage if you tow it on a trailer.
wrong ted. i pull my A on trailer with a 93 bronco 302 that gets maybe 10 mpg on a good day, a tale wind, going down hill.
That 10 mpg is on your truck. I thought you were concerned about the MPG on your A, which under those circumstances would be fantastic.
good point. so if my A gets 20 mpg normal, and an added 10 (trucks mpg) for being hauled, that would mean that the A gets 30 mpg while being hauled. so that is better than the mpg the A gets when being driven. heck fire, i'm just just going to haul the A everywhere.
I read in some old book someplace that at 18 MPH a model A would get 35 MPG, but at 35 it would only get about 18 MPG.
I figure my racer goes X mpg for my whole trip. Now, if I goes halfways, then I'm gettin' X/2 mpg. But then I'm also getting X/2 mpg on the way back. So since I'm back where I started that works out to all of my mpg's and I didn't go nowhere! Stick with me here. Now, if I WAS to go somewheres I'd be getting twice the mpg's, but after I come home I didn't go nowheres again so that's four times my mpg's ... as near as I can figger, the more I drive - the fuller my gas tank will get!
That danged Bruce was always such a show-off with his "the world is flat and I can prove it" routine. I figger if it really is flat, I can drive it but I need a few spots to empty my gas tank on the trip.
Oh yeah. That stupid fly isn't going anywhere if the windows are up. If'n he ain't goin nowheres then he's doing 0 mph ... sheesh ...
garnet. so then do i than surmise based on your calculations, if you were to drive your car backwards, your gas tank will fill and even overflow if you were to drive far enough?
