well, still better than my LX 3.8 that couldnt even get that far up, lol
I'm looking at 77.29 mph in 5th gear at 2000 rpms with stock 26.6 inch tires.
He's even slower at 115.93 (116) if you use 26.6 inches as the tire diameter.
Something in my head is sticking that a speedo only has to be within 6 mph to be considered gov't accurate? I have no proof, but it feels like I read it years ago. Time to research.
Either way, I'd rather be 3 mph lower than speedo than over.
Edit: Is this viable court defense?

By asking for the speedo and radar calibrations of the officer issuing a citation, if they don't have it, they can't support their claim of your offending mph?
Edit #2: Called a speedo shop. No federal regulation, just that manufacturers have their own. 2-3% is the norm. Also, he mentioned that as you go faster, your tire gets larger a tad so basing it on tire hieght x RPMs can be off. Also, how accurate is your tach?
