What are your RPMs at 80?

So on my latest road trip, I found myself at a bit over 2,000 RPMs when at 80 in 6th (only when passing of course )

Just wondering what you guys are all seeing at that speed? I know gearing is the main factor here, so I think my 2.73 gears have something to do with this low number. What about SS, ZL1 guys?

Ok, so you have 2 more cylinders and 3.45 gears (correct me if I'm wrong) so that seems to make sense at the moment

Wheel size also comes into play here.

I'm somewhere in the 2K range at 80mph, probably at least 2300 or more. I have 3.70 gears.

These numbers are for my '13 1LS M6 with 18" wheels. Change out the bold numbers for your own and recalculate.

The math...

KNOWNS
A = Vehicle Speed (in mph)
B = Wheel Radius (in inches) measured from the wheel center to the ground
C = Rear Differential Ratio (ie 3.27)
D = Transmission Gear Ratio (ie .84)

VEHICLE - Convert MPH to in/min
(80mi/1hr) x (5280ft/1mi) x (12in/1ft) x (1hr/60min) = 84,480 in/min

WHEEL - Convert radius to circumference
C = 2πr = (2) x (π) x (13.75in) = 86.39 in = 86.39 in/1 rev

WHEEL - Convert in/rev to RPM
(84,480in/1rev) x (1rev/86.39in) = 977.89 RPM (at the wheel)

RPMs - Work it backwards through the drivetrain
(Wheel RPM) x (Differential Ratio) x (Transmission Gear Ratio) = Engine RPM
(977.89) x (3.27) x (.84) = 2,686 RPM

Wow, that's really useful! It reminds me of AP Physics though
Thanks

Yeah, no prob. I also have a spreadsheet that I whipped up one day when I was bored that tells me the vehicle speed for any given combination of engine rpm and gear.

Wow! What program is this, or did you make it completely yourself? Very neat

(Oh and I only said the passing thing so I wouldn't get flak from people for cruising at that speed, but I do )

I think I am right in between 2-2.1k @ 80mph.
