Only other accessory running off the crank is the AC and alternator, neither of which I intend to delete (I'm a big baby when it comes to sweating  )
This discussion nearly makes me want to add some lead weights to the flywheel to see how it goes. |
Well considering metrompg gained 10% mpg from 70 to 77 in deleting his alternator, you could be hopeful that power steering robs a lot as well. This is an easy test as well cuz you can simply take the power steering pump off, the problem is if you don't loop the PS lines, it will be much harder to drive, but if you just do a small test then it shouldn't be so bad.
i'm in the same boat as you, I LOVE AC and won't be without it, I know it robs MPG probably a bunch more than this heavier or lighter flywheel thing would help or hurt, but its not a sacrifice I will make.
