Top speed isn't all it's cracked up to be.  The worn suspension and brakes on an 18 year old car are much scarier at speeds of 80+.

Si, but like Ifix said you may want to make the car ready for that kind of speed before actually achieving that speed.  I'd also recommend mayhaps doing ridiculous speeds on a track on a test & tune day where you are legally allowed to do so.

Unless you have serious mods you arn't going to hit thw 120mph speed governer on these cars by the end of the 1/4.

I hit 325 mph before the 60ft mark with no speed governor.

A Stang computer will not work on a SO Tbird engine... You HAVE to do a HO upgrade first...

The governor is set at 182 KM/H or about 112-113 MPH. You aint doing that by the end of a 1/4 either :)

Pffffft, that ain't nothin'...with my Allison V12 powered tricycle, i can hit 750 mph in 10 feet...;)

quicksilver, is this your first car?

yep first car, but my govenor is set at 85 mph, not 112-113.

Hmmm? I think you might be looking for the Bondocougar mod. I'll try to find it for you.

EDIT: I can't seem to find it right now. I'm pretty sure the governor is at 182 KM/H - I've tripped it many times. When the governor engages the engine just goes back to an idle even though you have it at WOT.

You have the digital speedo, right? and it stops at 85 mph? but the car keeps accelerating beyond that.

If you want the speedo to read beyond 85 MPH you will have to do the Bondocougar mod. The gest of this mod it that there is a spot on the speedo circuit board marked W2. If you solder a jumper in that place the speedo will measure beyond 85 MPH.

Yes, Paul is right.  The car only reads up to 85 but it will hit higher speeds than that.  Though it's not really safe to go too much faster.

When I engaged the governor, the car was only a year or two old.
 
With the worn springs, shocks, frontend, etc. I don't think I'd try it today.

Do you have a digital or buttstuffog dash cluster?

I did the mod on my speedo.The jumper wire is an easy job,you just have to be VERY careful not to solder anything else,as the two points on the circuit board are very close to each other.I got mine up to 144 so far.We'll see what happens after the new ported and polished heads are installed.I do the conversion on the standard speedos and put them on E-bay for $20 -$25.You have to disassemble the gauge cluster,remove the screws in the back of the cluster to remove the speedo module,and unplug the tiny harness that connects it to the rest of the cluster,then,disassemble the speedo by removing the "green screen" as i call it,and gently popping the little whit plastic retainers apart that hold the circuit boards together.You must be careful,or you're screwed.On the circuit board,you'll see a tiny little "W2.Next to it are two small "solder dots".Connect a little jumper wire between them and then the gauge can read up to 199 mph.I should've taken pics.I think there's a tech write up on the cool Cats tech center.I'll try to find the site for you.

It will go past 85mph. When you are going down the road and hit 85 push teh E/M button on the dash. The numbers keep going. You need to do the mod to make it read past 85 as stated in a prvious post. This (http://"http://www.coolcats.net/tech/advanced/199speedo.html") should help.

geesh I got 55mph and i get pulled over.... 140! 110!  i wish i lived where u guys do.

If your car is stalling and messing around after 85 u may have another problem?

I-35 runs through the center of Oklahoma from Texas to Kansas.LOTS of straight highway.Not many Highway Patrol.It doesn't take long to get the speed up then shut it down.Very cool,and a little scary with my stock suspension......but cool.Anybody with the standard gauge clust REALLY needs to do the 199mph mod.It's very easy,takes about 15 or 20 minutes if you take your time.Worth it.

Not a single one of these cars "stall out" at 85mph. My 3.8L did better than that.

Racing struts but stock springs? New front end and stock springs? I think someone is full of it.
