Donks get good gas mileage, right?

I mean, those big ass wheels, turning over so slowly lugging that small block chevy at low RPMs..... they gotta get at LEAST high 20's, no matter what kind of car it is.

polar moment of inertia probably disagrees with you, but who knows. The age and condition of most of the donor vehicles likely counts against it, too

hmmm, wouldn't THAT be an interesting take on an economy car... Needs more diesel...

I should assume so.

Kinja'd!!!

Big gas burning dually's from the 80's and 90's had smaller wheels and revved lower. They did not get good gas mileage. The wheels kill the gas mileage, they are heavy as shit and have more rotating mass.

Not sure if you were serious.

there's a lot... A LOT! of Nissan Altima SLABs in Houston. I'm sure it is at least ok. You loose torque having those giant wheels and the stock brakes (which they all have) must get worked hard

Ive wondered about that myself. In town driving fuel mileage probably suffers. But on the highway, they may do ok. Most of those cars come with 2.73-2.42 gearing. Then throw on those tall tires. And they gotta be doing something like 1200 rpm at 80 mph. Unless they swap gear sets and recalibrate the speedo, I'm guessing the shift points are all kinds of wacky too.

Yah but I want a box Caprice or a Cutlass or something.... a 2bbl 305/307 could theoretically get 30mpg if driven correctly. Right?

I wonder.... but for the majority that end up on Craigslist I doubt driveline modifications are made beyond the lift and wheels. S'why they're so cheap.

Hmm... how about a donk diesel Oldsmobile?

I've seen a few with some dollars spent under the hood.... but mostly it seems to be spent on chrome accessories.

But once they get rolling..... my drive is all highway, and when I put bigger tires on my Subaru my mileage actually got betterish.

So THATS why they only buy $5 worth of gas at a time! I've always thought they spent all their money on the wheels.

fact :]

600 RPM's at highway speeds.

you keep typing...I'll keep fapping.

But seriously yes that is a brilliant idea... Can it be a Diesel Donk Oldsmobile Vista Cruiser?

No no no, bigger wheels=higher rpm. It will result in poorer gas mileage. And not always by small margins.

EHHH, wrong. Larger wheels/tires have less distance to travel to cover a certain amount of road, therefore turning the engine slower.

Read up, yes it will lower your RPM, I was wrong. But it will not help gas mileage, there is a reason economy cars like the Prius and other hybrids have small skinny tires. It takes less torque to turn them. It might turn less RPM's, but remember that your max power and torque are still at the same RPM and you will have to compensate for the loss.

Those cars have no torque to begin with, whereas most donks built on old small block V8 platforms have low revving torquey engines.... and theoretically since I go mostly highway driving, unless I get stuck n stop and go traffic once I got up to speed I'd be lugging around at idle. Maybe.

I google'd "Do donks get good mileage" and surprisingly there were ZERO results.

As someone with a vehicle with larger tires, it does not help gas mileage at all. Where on stock tires I should be able to get 15-16 mpg, I get 12-13. That is not speeding either.
