To reiterate the question in more simple terms, how handily will a 3.92 geared Hemi blow the doors off a 3.21 geared Hemi?
Apparently...it won't.
Wow!
To say I’m surprised would be an understatement!
Thank you for that!
Can’t imagine the tires making that much difference. They must just work as good with the higher gears!
That’s because the 3.92 truck had larger diameter tires. So in the end the ratios were very close.
Running a quick gear ratio calculator, the little bump in tire size doesn't make up for the big difference in ratio. Picking top gear at 2200rpms is about 16mph difference, with the different diameters.
Plus looking at the results a little closer, the 3.92 /bigger tires pulled a bit quicker towing, which tells me it actually should be quicker empty.
I'm now surmising the results were from 2wd launches/traction control doing its thing, inconsistent data or inconsistent runs.
