I know my old automatic RS could do 130 in overdrive,and I guess it only had 4 gears

 

I have an '86 2.8 MPFI w/5-speed.... My spedo only goes up to 85, but I dont have a trip-odom so Ive gotten that bastard to wrap around to 15mph.....so im guessing thats like 110. Which I guess is kind of fast seeing that I dont have z-rated tires (car was vibrating bad)and the stearing is sloppy. She could have gone faster maybe an other 10-15 mph but I ran out of straight road...that and I didnt want to die...

 

I have an 85' 2.8 5 speed, i was racing a friend on the freeway we where nex to each other and he had his needle bouncing off the trip odometer at 120, so i'd guess we where going about 135 or so.

ive done 140 and the rpms were almost red soooo..145-150 is about top.

Well I've had my 92 5 speed up to 110mph and then it just sat there and bobbed and I just kept getting faster and faster until I redlined 5th gear. So I cant tell ya. All I know is get it up to about 95mph and then shift into 5th gear and feel how much the stick is shaking. Nothing like it

 

I've got a an 85 5speed 2.8. My speedo goes only to 85 but i got it to go back around to 15. i measured the gauge and it comes out to 125. but i noticed that the speed doesnt go any higher, but the RPMs still climb a little more, but not to redline... according to the tech section, if we had the power, we'd be able to get our v6 5speeds to 176MPH. i'd say true top speed was 130. oh and that was with the windows down at night. hehe, payce!

I would imagine the 2.8 is the same as the 3.1, If I can cut my gov then mine I know can do 140ish..at 115 where gov kicks in I stll have 2200 RPMs till red line and I have tipped that red line quite a bt doing burnouts...

 

where are you guys getting your numbers? we all have top-speed governors @ 115. My car can't go over 115. I've had a huge stretch and tried and tried. half way through the 2 1/2 mile strech I was already doing 110. then, 115, but no faster. as soon as I get my fastchip. Then I'll see what it really can do. I have the 145 mph gauges, so I actually know my top speed. no guesstimation here.

what about a 2.8 fully moded out.????everything possible????

 

Nope,not me.

 

Off governor I was told 130ish.....

 

Put it to a this way.. My buddies went to 120 and we were beyond that....

 

i got around up to 153 i was in the red i think around 6500 RPM's

 

153 is the top speed of an LT1 Trans Am. Never will I believe a lightly modded 2.8/3.1 can hit this speed. Realistically something like 125 is what Id be satisfied with in a V6.

I've got a v6 5speed myself and i have to disagree with the 153 top speed. Our cars, even moderatly modified, just cant reach that speed. Drag is an exponential factor and is difficult to overcome. Sorry to say but not many of our v6's are making nearly as much power as the big v8's, and even they have trouble achieving that speed. If you're reading off the speedo, better luck next time because those things are usually off anyway. Your best bet is to ****** a radar gun and spec it yourself... anyway, just my opinion... payce!

GramesFirebird if you really do have one ill take you up on that offer.
Also to all those who say it isnt possible i know my speedo goes to 110 but then you go into RPM's wheel diamater tranny geear ratio and all that and it will give you your speed using RPMS. So grammey if u want to late one night ill prove all these guys wrong

 

i may have to disagree with 153 to because i have a 89 cbr 600f2 honda piped&jetted.that goes 0-60 in 3.0 seconds and my top speed says 200 but drivers race tests only show atop speed of 165 and i my self have had it to 125mph for a short burst and my bike is kicking out 93 horse power.mind you that this bike was used as a race bike 3years ago and then it had different gears for the track
just my opinion. ps that 0-60 in 3 sec is only if you know how to hold on tight and dont miss a gear while shifting.


[This message has been edited by bub (edited April 03, 2001).]

 

do you know your exact tire radius and diameter? Are you sure about the tach reading exactly 6500(shouldnt really be looking at gauges at that speed). Did you type in the right drive ratio? It you biff up one of these #s, then the speed result will be WAY off! Id really like to see this radar checked.

 

Don't forget to add a lil to the tire radius. At that speed, your tires balloon in the middle because of centrifical force. And yes, it does make a difference.

 

Ya i posted this a while ago at first it said i was doin like 180 something then i poseted what i needed for the tire diamater and the gear ratio and figured it out from there. and i glanced at the tach it was on a perfectly strait road. But i know it happend last time i poste dmy top speed i got the same bull**** and its pissin me off

 

Dont get mad FastRS (I still havent heard any times from the track so we have yet to see if your screen name is a lie like your top speed) that we called you on your bull$hit. You are still the hotshot of the v6 board. HAHAHAHA.

 

Dude what ever first off i want to go to the track 1 problem its like a 3 hr drive from were i live. Also i know ive gone that fast and when i was doin 135 on the freeway my frineds 79 z28 with a 140 speedo we were side by side and he even cnfermed that so you know what i dont give a **** what you think i know it happend. Hey why dont u coem to my house and i will show you my speed. Ive done 80 in 2nd gear wait im sure to you that inst possible

 

Ha i found the post look how high tom p's rpms were at 137...
https://www.thirdgen.org/messgboard/...ML/000275.html
Oh and i had the tire diamater wrong 3.1firebird helped me figure it out so i could get it right.

[This message has been edited by FAST RS (edited April 03, 2001).]

 

somethin ain't right, there is no way a v6 is gonna roll 150 mph. you are on crack. think what u want, i'm not callin a flame war here, but that claim is bull, and everyone here knows it. so quit kiddin yourself and admit that v6 cars top at about 130. i don't care what your response is because you can never prove to me that a v6 will go 150. so trash me all u want, but i'm just sayin what no one here had the ***** to say.

Ok what ever i told the truth i know it happend my frineds know it happend thats all i care.

 

I'm not saying anything except I know that MY CAR won't go 150 unless I was goin down a straight mountain road with a tailwind, with lots of weight in the car, and had some magical "no wind resistance" bubble surrounding me.

 

me my dad and my friends grabbed 3 cars from his lot last weekend, a 2000 Trans Am, a 2000 SS and i got stuck with a 1997 3.8L V6 5 spd 30th aniv. adition i hit 150 plus or minus a few and they were gone (we were racing on an open highway with no cars) so i just took an exit and headed back, but it is possible for a V6 to hit 150 cause i know i was at it. again like he said, u can flame that comment all u want, but i saw the speedometer and thats all i need.

im out.. pe@ce

 

Try out http://home.earthlink.net/~jonaa/topspeed.html On the bottom of the page is an Excel file that calculates the top speed. It is kinda neat and seems to be reasonably accurate.

The only problem is that you need to know the drag coefficient and frontal area of your car. Shouldn't be too hard to guess/look up a good number.

yah, but that 97 v6 will run a 15.2 second 1/4 mile and even lower. i know because my friend was lined up in the lane next to me, and with a 1.161 reaction time, he still ran that 15.2. sorry about not capitalizing, my shift key is messed up.

 

I used the topspeed calculator on the board its when you first come to this site under formulas i think

 

The equations section of this site only tells you that at X rpm you are going Y mph. This Excel file calculates how much hp you need at X rpm to get your car to Y mph. The answers are approx only. I would guess the error to be +/-5mph

Sorry for the confusion
Dale

 

'sal good overclock atleast u paid attention to my post lol!

 

I might believe the V6 4th gen thing if I didnt know that a 4th gen V6 speedo only reads up to 125 or so, the Z28s read up to 155. There is no way a V6 car can top out at the same top speed as an even more aero dynamic LT1 car tops out at. The LT1 top speed that I got was reported from motor trend and was radar tested!

 

the night i did it i was allready at 100 or so then i put it in drive and floored it it tok me around 10 miles to get up that high from 100

 

ok, this is gettin out of hand. Responsible drivers shouldnt' be going that fast anyways. Consider it locked.
