Aren't you a little worried about your tires flying off at those speeds? I saw that happen (on the news of course) to a stolen superduty that was involved in a chase near calgary a few years ago. I'm scared to go past 85.

The tires I am running are over 230 each last spring, if they fly off I will have someones behind wrapped around my boot toe.
Besides, the Dodge boys would never be able to stand the "My Ford went so fast I ran the tires off it" story.
Since my speedo stops at 85, the 2003 3500 Ram Cummins I was playing with told me we were at 102 MPH before he started pulling ahead of me.
I have since installed a set of Stage 1 injectors, we are going to have to play again, soon.
You all have no idea how much fun I have with my old Ford.

Actually I was wondering if there is a maximum safe speed for tires that are not rated for the strip, but I guess its all subjective, and also way off the official record
. My f150 has an AOD tranny but I've never been past 85 with it for fear of loosing a tire (definitely not $230 tires).

You guys are a bunch of WUSSIES!
I've had mine over 85 several times, and I'm running a set used tires I only paid $100 for (all 4). Of course they are 10-ply Goodyear MTRs - but they have only about 30% of their original tread left.
Exactly how far over 85 I was going I can't say - I didn't happen to have my GPS with me at the time. All I know for sure it that the speedo was pegged and my foot wasn't all the way to the floor yet

Hey! who are you calling a wussy? I'll have you know that I routinely hit 85 if I feel like ramping up before a steep hill. I've just never tried to go faster.
In case you haven't noticed, I just might be a lttle full of it
.
I have to admit, I was quite suprised when I first opened mine up to see what it could do, but I never actually floored it ot see how fast it could go. I got the feeling that I would have hit the governor before I ran out of hp. My tires are also used, but I have no idea what brand they are-I was desperate.
Why does the speedo have to peg at 85 anyway.
I knew a guy who had a 1976 f250 with a built up 460 in it, I'm not sure, but I think in that year of truck the numbers would max at 100 (my dad had a 1975 that did), and he was able to spin the needle all the way around to zero and beyond. Hmmm.....maybe I am a wussy after all

Remember in the late 70's and early 80's the feds were pushing a 55 MPH speed limit on everyone everywhere.
85 was 30 MPH over the speed limit, reckless driving, wasting natural resources or several other charges were added to the speeding on the ticket.
Also with 3.55 gears and the stock transmissions of the day, 85 MPH was max speed anyway at 3300 RPM.
