I have never been over 70 in my Fiero. However,..I did go 143 MPH in my 88 Cavalier Z24 once. It has a digital spedo and cluster. Damn near threw a rod doing that. Redline at 143 in third gear. (automatic) The cool thing is that when the VSS started going out in it, it would read totally random speeds while driving. One second-57 mph, the next-583 mph. ect. ect. It was great when it got stuck on 236 mph on the freeway once. Gosh I wish I had a digital camera then. Would have been a great pic. Just a note: My high speed was a one time deal. I was going down hill, on a very long stretch of road with no cross traffic or turnouts. It was at night in clear weather and no wind. At the time I felt totally safe. But now that I think of it..I sure as heck wasn't. If I would have thrown the rod, it would have killed me. If the rod didn't hit me, I would have lost the car. Either way, the thing wasn't made to go that fast and I shouldn't have taken it nearly that fast. I am normally a law biding man but I had to see what the limits were to this vehicle. I did, and now I have my bragging rights. I know a guy who owns a Hyabusa motorcycle. He took the thing 200 mph once and he damn near crapped his pants doing it. The slightest wind and he would have been a goner. Even though that bike is made to do well over 200 mph. Point is...don't speed like that on roads that aren't meant for stuff like that. Go to a track. had to add a pic of the Z24

3071 lbs car. Were you giving me a convertible? how nice of you orief. There is a limiter, cuts fuel after about 4000 rpms in 5th gear. That's another 10 mph easy. But like I said, you can magazine top end, I'll do it on the highway.
81? Wtf? I can do 81 in 3rd gear.
[This message has been edited by BlackStang95 (edited 01-09-2002).]
I had the Fiero to 5600Rpm in 4th , which is around 138mph or so with the tire correction taken into acct.
I don't want to flame any of you , but do you have any idea how innaccurate your speedos get the faster you go?/
A 6cyl stang hitting 130mph , your pushing too much air and don't have the right gears to keep it in the Torque curve. My guess is that if my 95 5.0ltr pulls off 130 , with the same rear gears , and an overdrive tranny in which I can hold the tranny out of OD (Ie in the torque curve) than your 6cyl probably pulls off high teens low 20's top speed.
It's all about torque , gearing and wind resistance when it comes to top speeds. Don't look at your speedo and think it's correct. Take the engine RPM , and the tire diameter and use that. Speedo's are very innacurate at high speeds. Even Ferrari's have been tested as being 10mph optimistic in the top end.
This wasn't to flame anyone (Blackstang) Just pointing out a few things.
If anyone wants a few formulas to play around with to get proper top speeds let me know and I will post them
As for my personal tops (not driving) In the vette we wound it out to 162 corrected mph ( the digital read out was displaying 170) , and the 911RS..well... a lot faster

143mph in a 1994 Caprice I didn't even have the pedal all the way down . And the car felt unbelieveably stable on the road. It was an old police car, and it had a fresh rebuild with some performance mods. The only things I know of for sure were the headers and the exhaust. I don't know what my dad did to the internals though. I suspect it would of topped out at around 150-155.
My 88GT, somewhere between 120-130. My 87GT, around 85mph. I'm afraid it'll blow up if I go any faster.

I'm not exactly sure, but I would guess it's been well over 200 MPH, maybe even 3 or 4 hundred. I was a passenger in a boeing 747 Felt a lot slower though.

About 123 - 124 MPH (just about 200kph) in my '87 GT. This was right at the needle on a flat stretch of highway (don't know about wind). I had no cat and this was before my engine rebuild (it had 175,000 kms on it then, or about 110,000 miles).
I haven't tried since going to a 3.1 with perf cam and headers.
The older I get the more scary it gets.

Had to bale my cousin out of jail for speeding and reckless driving when he got his 89/90 Dodge Spirit R/T up to 167 mph in Corpus Christi, Texas. I got arrested for doing 156mph in my Dad's 93 F150 with a 302 running a bi-fuel setup. And yes I know 93's were supposed to have governors on them but tell that to the judge for me
If you want a Ford F150 try to get one of the premiere editions of 97, they were sold in 96 and had 315 hp 4.2 v6. Which they weren't supposed to have. The lucky pre editions did not have fuel cutoffs and ran 15 quarters stock. My brother bought one december of 96, xl with a 5spd. after hitting 145 in 4th at Alamo Dragway they had him dyno it. Truck never hit top speed that we know of. Too bad it met the wrong side of a retaining wall while racing a cobra at the track He has the documentation somewhere for it, I'd post it if I could find it.

The needle hits the pin at about 4100 rpm in 5th, took it to 5700 rpm already, and it was stil pulling.
My V8, no clue, 85 mph speedo in that. But I did have it to the point where turning the steering wheel didnt change the direction of the car....... havent done that again, needs hood vents in a BAD way.

This car never had a governor and never will. The 1988 Chevy Cavalier Z24 of this year has no governor. If you look closely, you will see the 2.8 l emblem on the side of the car. I have since replaced the engine with a 3.0 that has been bored out to about 3.8. I know of no governor because I inspected the tranny myself looking for wear when the engine came out. Other mods are a two inch drop on a Lotus suspension, 17 inch rims with 215 45 17 Yokohama tires, giant headers (that I admit have been milled one to many times), high pressure oil pump, high flow K&N oil filter, Hoki ignition, K&N air filter, four wheel vented disk brakes, tinted windows, a performance stereo with only the latest technology of Fosgate and Clarion, and One, count it ONE sticker. A small Chevy sticker with an American flag in it. I call this car..."The Mustang Ruster"

I've only had my Fiero up to 100MPH, but I know there is more, and didn't want to push the engine too hard after just breaking it in. On the other hand I drove a Mazda RX4 to the red line and the speedo said I was doing 150MPH.

Just incase you may have thought that it was the vss telling me that the car was going 143, it went out before I even got the new engine. I replaced it before I went that fast. Besides, a guy at my work won the state lotto (about 29 mill) 5 years ago and took me for a spin in his Lambo. We went 136 mph in that on the 101 between Ventura and Santa Barbara. That was fast but it was daytime and that freeway has too many turns to go any faster. My Cavalier was going faster. Big diff 7 mph does to your pants. lol

The mustang ruster? What is it with everyone going after us? Oh well, bring it
You might stand a chance against my v-6 but youd get smoked by a v-8. There's a guy in my auto class with a late model (2000 or so) cavalier that he as i call it, "lexusized"...real hid lights, all chevy badges pulled off, body kit, big chrome rims, low profile tires, fully riced out interior, etc. We went at it on a 55 mph semi-residential road with quite a few curves in it and he was always behind me. You sound like a domestic ricer to me. Only a ricer would list a damn OIL FILTER is a performance mod. Does that add 20 hp? Thats just an extra 8 bucks you could save every oil change...

Yes, 1988 Z-24's with the 2.8L 5 spd, and autos did have a Speed limiter built in the ECM. It is set for 170kph, or 113mph.
If your car does not have a speed limiter, it either has an aftermarket ECM or Eprom.
I know the 92's with the 3.1 will hit 190kph before being speed limited

Nothing against you balckstang, but my car has been mistaken for a Mustang too many times for me to admit. The oil filter really does help the car stay cool and boost performance. I have dusted a few mid to late 90's mustangs on the freeway but I have yet to really line up a race to a V8. Don't pay any attention to the newer Z24s. I have raced the "ricer" or "import killerz" Z24s and killed them all. The J body Z24 was the superior of the Cavaliers. The newer ones are just junk in my opinion. I don't hate the Mustang. I actually like the new Mustang body style. But its still Ford in my mind. I have worked with Fords and Mustangs and they have a weak point where the crank meets the piston. The trannys are no good in Fords either. I know this because my work has about 50 units in it's fleet and all of them are Fords. Ranging from Broncos, Mustangs, Taurus, Ranger, and the F150. And after about 80 thousand miles..all of them have tranny problems. Not to mention the cooling problems inherit to Fords. Also performance parts are way too expensive for Fords. Especially Mustangs. I personally like the 65 Ford Falcon Futura with the 302. Good looking car. I just don't like it when everyone I meet at the beach says to me.."Is that a Mustang?"

That could explain why the glove compatment was ripped out of the car when I got it. It was so bad in that area, I had to get a new case for the heater core.Besides, have you ever had a bigger engine installed on a car you didn't replace the ECM?

Well, down here in Louisiana there is a town called Holden. It is hwere the Hood boys live (Parents own a company that makes Log Cabin homes) Anyway one races rally type racing he owns an Original Cobra the other one has a Late model Trans-Am with a 455/454? SD Anyway I went with them one late night out on the interstate for one of there constant on going battles to see who is the fastest. Topped out at 181 before they backed off, it was quit an experience to say the least. the line markers on the road all become one solid line.

Broke my 140 mph speedo by exceeding its limits too many times. (in a 67 Sunbeam Tiger) Over 100mph in a 78 Landcruiser. Chickened out, But it felt Stable. Smart to back out, not smart to be there in the first place.

No flame here, you did state that " The 1988 Chevy Cavalier Z24 of this year has no governor." Thats what I was correcting on.
Also a carbed engine swap doesn't require an ECM.

I've been a passanger in a 2001 mustang V6 rental car. Was doing 110mph and it still had some good pull left in it (this was an auto also). With simple mods I'd beleave a 130mph+ top speed. It was a pretty quick car.
The guys with 3800 fbodys claim 145+ top speeds with minor mods. But the fbodys are a bid faster then the stangs.

whatever 87fierogtx, go get a $10 oil filter and youll gain 40 hp and 20 mph in your top speed!
tranny problems? 130,000 miles and counting on my t-5. Cooling problems? Never past the O on the NORMAL gague (reads from left to right). Performance parts too expensive? Nope, comparable to other domestics and still well cheaper than the imports. Later
Originally posted by ejayerik: I have since replaced the engine with a 3.0 that has been bored out to about 3.8.
Wow! What kind of engine did you start with? I've never heard of one that could be bored out that much. Did you stroke it too?
quote
I know of no governor because I inspected the tranny myself looking for wear when the engine came out.
Speed limiter would be programmed in the ECM, no attached to the tranny. But you later said you had a different ECM, so that answers that question.
quote
Other mods are a two inch drop on a Lotus suspension,
Tell me about the Lotus suspension? What's it include? Did it come off a Lotus, was it designed by Lotus? I like the old J-bodies, but hadn't heard of this mod before.
quote
giant headers (that I admit have been milled one to many times)
What do you mean by "milled" headers?
Sorry for all the questions. I really like the late 80's-early 90's J-bodies. I'd love to find a Sunbird with the 3.1V6 and a 5-speed, preferable a convertible! Tell me all you can about your mods. I'm very interested.

Thats cool. I know the Z-24 that I owned had a digital dash as well but had a speed limiter in the prom chip of 113. Had PLENTY of power left but would not go over the 113 mark. It was an 88 5 speed. Kicking little car.
The fastest I have gone on the street was 147 as a passenger on a Yamaha XS1100 back when I was 21 or so and living in Va Beach. We were cruising up 64 towards Chesapeake. I was wondering why we were zipping past cars so fast, had to fight the wind to get a glimpse of the speedometer. Needless to say it was one of those " Hey, slow down! I wanna live!" Moments
"Raced That, Wrecked Better" 
. And the car felt unbelieveably stable on the road. It was an old police car, and it had a fresh rebuild with some performance mods. The only things I know of for sure were the headers and the exhaust. I don't know what my dad did to the internals though. I suspect it would of topped out at around 150-155.
