With the speed limiter moved or disabled, what do you guess think it would be??? I had the WS6 to 170 with only a catback and think there is a small cam in it. I had the 99 slap the speed limiter bone stock which is 161-ish. I know a 3.42 gear(t-56) in 5th tops out at around 185, I know it won't reach that unless it's down hill with the wind pushing ya maybe and a road long enough. I don't know it has me thinking. Has anyone done it or know?

well stock speed limiter is 162, i think maybe 172-175 stock

keep in mind, speedometers are only so accurate. I remember reading years ago in a bike magazine, testing the stock speedo's, they were all measuring way on the high side, not even close to accurate. I'm not sure about these cars, but better off to find out with a gps or calibrated radar gun if you know a cop maybe...

Mine went 158 GPS .Bone Stock auto at the time.

Shooter_Jay

out of curiousity, any idea what the speedo said when the gps said 158?

Shooter_Jay

oh wait it only goes to 145 or whatever my bad ha

Its weird, I remember when I was going to vegas I was doing around 80, and on the speed signs it read 84?

I would have a hard time believing one would do 175 stock. In fact, I don't believe it at all. The 2001 Z06's would top out 5th at 171, and they're a good bit more aerodynamically suited to the task. It takes a LOT of power to push an F-Body over the 165 threshold.
I've done a lot of top end "banzai runs" in my day, and you can get up to about 160 without much doing, but after that your car fights for every mile per hour, as aerodynamics really come in to play.

Z06's went 171mph and the Coupes(targa's) went 175mph top speed. Something about the drag coefficient is better or soemthing~Cole~

When I was doing my runs I only took rpm and applied it to the gear calculator which you would have to do on a fbody because the speedo only goes to 155 anyway regardless if it's right or wrong.
I already know it can go 170 with some mods without a problem and still could have gone faster, did that 2 weeks ago. Only reason I slowed down was I had missed my exit and got off at the next one.

Not saying it would do 200 or anything but could have pushed more out.

i gps'd 155 mph in my 2001 camaro SS back when it was bone stock

I stopped my speedo in 5th gear around 5500 or so, then drive to 5,800 or 5,900 in my 98z28, mine never came with any speed limiter. I would hit mid 160's, limited by power at the time, switching to 6th gear it dropped the rpm a lot but it wouldn't pull at all.

6th is way to tall to push unless you have some serious (700+whp) power

As far as speedo accuracy, i know mine is dead on. Gps reads 75 at 75 and 110 at 110. Ive only pushed my car to 145 stock, but it had more in it. After the longtubes, 3 inch td exh. and small cam, i know it will push 160, but, i dont know if i trust its stability at those speeds.

The higher the RPM's go, the larger the difference between vehicle speed and what the speedometer reads. Just food for thought.

5% error is legal, do the math. That can be a big error especially over triple digits.

Z28*Reborn*

I got to 150 really easily bone stock, i wouldnt doubt if someone said they hit 170 on a runway but i dont think you could get past that. with enough power im sure 6th gear could get over 200, wouldnt want to see it though

I have a ctvs and I will never know. I am 46 and 150 doesn't sound good to me anymore. I think 125 to 130 will suffice for me. I just want it to get there fast. Priorites change with age. My mods will be around getting there faster. I don't think 160 sounds good to me without a cage and harness. You younger guys can take care of the top end stuff.

Back when I was crazy I could bounce my WS6 off the speed limiter (162 mph) bone stock. Took a little while to get there. Without the speed limiter it revs out to 167. With the turbos I can barely pull 6th after I top out 5th, but I've only done it once. Made it to 170. Takes a LOT of power up that high to pull anything.

Interesting note, I couldn't hit the speed limiter w/ the T-Tops off.
