Community Q&A Question: RPM at highway speed

Asking About: Mustang Ford Performance 4.10 Gear Kit for 8.8" Rear End (10-14)


RPM at highway speed

Could you tell me what rpm my 2014 V6 auto would be making at 70 mph with the 4,10's? I have the FP6 package which came with the P235/50 ZR 18 97W tire/wheel combo. Thanks in advance.

Accepted Answer
At 70mph in 6th gear with the 4.10 gears in your 2014 V6. you'd be right at 2400 RPM.

Actually, I made a mistake. I used the GT 6th ratio of 0.65 when I made my calculation. The V6 uses a 0.70 6th gear ratio, and that would get you closer to 2550rpm at 70mph. - Jonathan 4 years ago

Thanks Jonathan. I was hoping to stay under 2,500 rpm's. Guess I will think about it a little more. :-)
