with the old na 2.8 i belive it toped at 115 auto trans with 3:42 gears,it took forever was out on the nj turnpike.i dont thinkt he 2.8s had a govener function in the ecm just no power to go anyfaster.iirc the 3.1 dosent hve one either but dont quote me on thta one i never really looked into the 3.1 speed density code

My old 2.8 would top out at 110 (I only had S rated tires and I didn't want to push them), it had a 5 speed and 3.42 gears. Its top speed was higher than my mostly stock drive train IROC Z28.
I could sware my 2.8 all ways felt like it was built to do 80+ in 5th.
The 2.8 didn't have a speed limiter, I guess they figured it was "just a V6".

The Z28 tops out at about 100 because if you give it more than 1/3 throttle it down shifts out of OD into 3rd gear and pulls about 6000rpm, where it seems like it makes no power.

Really, If I'm on the on the highway doing around 85 and I punch it, my little 2.8 pulls pretty damn hard in 3rd, I had it around 115-120 and it didnt take more then 2-3 minutes max, it deffinatly had more just not the time or place.

I've buried my 115mph speedo before. I don't know what you guys are talking about. Might be a fun data log. I'll see if I can get it going and post some results.

Dale

iTrader: (12)

Fastest that I know my old v6 went was 96mph. Clocked in a 55 zone. It was the first drive I took the car outta the neighborhood after installing the 3.4 block.

Id say similar speed to that in my v8 car.

the 3.1 does have a speed limiter on it. I forget what its set at.


The GTP I have had at 129 several times. It really starts to "float"...

IROCtheThird

iTrader: (15)

I think firebird1992 is just curious to how other 60*s performed, like i said 115-120 at 3500 rpm with more left. Also that would be a fun data log, I would like to see that.
Dale, was that a grand prix GTP? I had a 95 GTP with a 3.4 DOHC that shut off at 115 and even there it would float bad.

Blue1989RS

Ah. Then I'll hook it up. I think my computer knows how fast I'm going. My speedo has been way off since the 4.11's. Lol. Its about 15% off. I go about 75 to do 60.

firebird1992

i see there alot of people out there that push there v6 mmmm nice to know these engines can take that kind of beating i cant wait to pop a 75 shot of NOS and that it on NJ turnpike or 1&9 express and open her up again lol still try to post the video its like 10mins long lol

Dale

iTrader: (12)

IROCZ, yes that is a 99 GTP with a few mods but nothing major. Forgot to turn on the siggy.

It gets up to 100 easy. It takes a little bit of work to get that extra 29.

Blaze of Glory

I've hit 115mph before and I have the speeding ticket to prove it.

iTrader: (1)

yall fawkers make me want to go find a nice stretch of road and see what my car tops out now with the turbo and new motor.theres just really no place around me except the parkway and the only area to do that is down near the shore.not a smart idea in the summer months cops everywere. im willing to bet i could bury the 145mph speedo

project89

iTrader: (1)

actually quick math shows 134 mph with the 4:10 gears @ 7000 rpms in 3rdgear, so thats were the car would top out unless i put the 3:42 gears back in max speed would be 160 mph with 3.42's @ 7k rpms in 3rdgear.


hmm i really wonder if the car would pull it, to bad u cant go wot in overdrive,well u can butit would burn up 4th gear in a hurry

firebird1992

mmm i wonder if a firebird or a z28 iroc would hold up at 145 even 130,
i know my car was screaming and so was everyone on the road that night

COME ON MORE STORIES TAKE IT TO THE LIMIT

bl85c

iTrader: (2)

I've got 3.23's and no rev limiter w/ my '165 ecm, I might have to do a datalog on the highway to find out what my limit is.

Picolini

I just hit ~112mph the other day, fastest I've gone in my Camaro yet. It was in about a 1 mile distance (starting at a 70mph roll, 0-70mph in about 1/2 a mile), 90% throttle... don't see how it took 8 miles to get to 119, I could have kept pulling a little bit more but the road was going slightly up hill, into a sweeping left turn with an on ramp at the right. Too much risk of other cars and possibly police at that point.

Kevman

175 km/h, 4th gear, windows down, my buddy in the back seat couldn't keep his hat on...

IROCtheThird

iTrader: (15)

I've had my IROC at 120 sumtin and it felt like I was doing 70, but 115-120 in the Sport Coupe felt the same, the IROC just felt "heavier". The Car and Driver article I think it was, topped out the 87 IROC L98 at 149 and change. But back to the important stuff, in a few months when the little beast is done I'll update you on a v6 top out run.

firebird1992

idk why but around 90-97mph it just lose all power and no matter how much u floor it , it just sits at 4400 rpm and after about 3 miles it pop in or out of gear and went to 119 no problem maybe i have a engine problem

IROCtheThird

iTrader: (15)

You have an auto I take it? Put in the Drive selection with out the big O around it, thats drive w/o overdrive (in other words 3 speeds) and you'll notice a big difference, mine got to 115ish no problem, and had plenty left. Forget about performance in overdrive, all overdrive is good for is gas mileage.

firebird1992

mmmmm never try going all the way over a 100 in 3 gear mm sound like a plan but if i buy that bypass so the trans goings in to 4th gear will that burn it out or something i had my friend tell me if i force it with a bypass i can kiss O/D good bye ooo

and MORE STORIES COME ON TAKE IT TO THE LIMIT LOL U ALL KNOW THE SONG

IROCtheThird

iTrader: (15)

Not at all, there is a reason you have the option, its for more "power" like if we had s-10's and were towing something, you wouldnt want to use overdrive, I wouldnt worry about it, youll just get crappy gas mileage. Dont neutral bomb it or do to many rollbacks and your tranny will be fine, especially with the minute power we have stock.

firebird1992

ok then i will try 3rd gear next time i just hate to redline my engine since i have no rev limiter but these cast iron bricks are pretty strong so idk i hope its strong anyway im about to put NOS on it in the next month

IROCtheThird

iTrader: (15)

You shouldnt have to redline it, redline is 130something in the 3rd, maybe higher, I was doing around 115ish at 3400rpm in the 3rd, thats with 3.42's, I think you have 3.23's so you should be fine. But yes these little 60*s can take a serious beating. Can you take a video of you doing a WOT pull on the highway?

forkvoid

iTrader: (1)

I topped at 122 coming across I-40 in New Mexico. Had to use a TI-83 calculator to get the speed(had my passenger time between mile markers over a five mile stretch and average it out). This was in a 170k 2.8 with auto and 3.42.

ScottieB

the 2.8 in my 89' governed out at 119 mph... took it there many times

project89

iTrader: (1)

2.8s dont have speed limiters they are set to 255mph in the ecm prolly just no more power to go anyfaster

firebird1992

Im trying to post the video but its to big for youtube but im going to try again this saturday at night to make a shorter one wish me luck

project89

iTrader: (1)

to big for youtube? youtube lets u upload to 100 mb, if u have windows xp open windows movie maker and load the video and then save the movie file u can shrink a 200mb video down to about 20mb and still have good quality

Picolini

I'll try and get a video of a pull up to about 110mph, probably Saturday since I'm off.
I got my cat taken off yesterday, so you should be able to hear the engine over the rush of wind now

oxrabidus

i dont know how fast i was going or how accurate the speedo is after the may speed which nine is the 85 mph speedo... but one time i got it to go all the way around back to about 15 mph... but i dont know how fast i was really going also my speedo does not have the thing to stop it from going around again... all i know is that is the fastest i have ever gone... and it was FAST... i would guess like 110 or something... but considering i dont go very fast alot it seemed really fast...

enswrob

had mine to 115 and a 1/4 peddle left.. bah..

zs&tas

had my 92 auto hit limiter loads - still pulling it was like hitting a wall, once it gets there............................................. its all very quiet and cruising feels like doing 30 haha

my current 88 manual feels much faster dosnt pull as well though

KBcobra

My v6 broke 110mph before I ran out of road. It did 100 in less than a mile. With 3.42s it was about 4500rpms @ 110mph in 4th gear. It was a year ago. It doesn't take long to break 100. Also it was quite stable at 100mph.

grimmcs

iTrader: (1)

Ive done 65mph in a 65mph area before


I see no need to do anything like that on the street and possibly lose my car...or anything else that could F up my future (ie. Hit other cars//people//lose control and get hurt)

Just not worth it IMO on the street.

forkvoid

iTrader: (1)

100% agree. I was younger when I did that and it was incredibly stupid of me. It's rare that I'm even five over the speed limit now.

oxrabidus

that is true...i was younger when i did that...well not that is not so true it was a year ago (i was 18...), but i had just gotten my car and i was cocky (you all know how a guy gets when he gets his FIRST car, with HIS own money, and in HIS name, with HIS own insurance policy...haha) and i raced a Camry, just BARELY beat him...so i figured out REALLY quick that... "DAMN...my is not so fast at all..." but ever since then the fastest i go is maybe ten over...and thats when i am rushed...

KBcobra

When I was 16 I was the same way but now since Im 17 its not that much fun as it use to be and gas kind of kills the fun. Though Im more than happy to ride in my friends T-61 Supra .

chevyracingrox

my friend let me drive his stock 89. i took it to 103 and backed off because that thing was scaring me. i was holding the steering wheel way to the right, and it was sloppy response so I didn't push it. I've gone 108 in my cavalier and my all time top speed is 137 in a 06 cadillac STS. I would have gone faster in the cadillac but there was a truck coming. it would've buried the 160 speedo easily.

92RS3.1

5.768mph on my John Deere Riding Lawnmower
42mph in my cousins Porsche 944 (damn conservative drivers)
97mph in a Chevrolet Colorado I-5
112mph in my 92 camaro 3.1 (rev limit)
116mph in my and my friends Jeep Cherokees 4.0 H.O. (rev limit)
118mph in a 94 Ford Windstar MINIVAN
132mph in my Moms 07 Toyota Camry I-4 (too fast for a plastic car)
184mph in my cousins 94 Ford Mustang in 4th gear

Thats my top speed history. I hate to admit it but, the best was the 94 mustang. 5-speed, diff rear end, and lotsa work on the 4.6.

I've never really experienced whiplash from a motorized vehicle before or since that majestic ride down one thin *** and bumpy as hell country highway.

Friguy

Yeah I got a 89 firebird 2.8L and I topped out at 116mph on the freeway. I let off because the car was shaking and it was in mid day.
with a loud *** exhaust I think its an imitation of flowmaster.

that was the only time I taken it that high, most of the time I only hit 85 to 90 on the streets. some back road.

my bird needs a radiator. major leak, I don't know if I can weld it or not, the water just pours out all over the cylinders. what a mess. oh plus I have to smog it, which wont pass.and tags and insurance, car sits, but I start it up every 2 or 3 days. so it don't drain the battery. oh and I also need new front tires and breaks and rotors. also I had to rebuild the trans, had a shiftkit on it.


the trans works fine now, so once I get all the other things fixed I am gonna do another speed run.

because I know at the time I maxed out the tires were kinda wearing out and it was before the trans rebuild. and I had problems.

and once I do that, next year I will save money and do a swap I want to do an LS3 motor swap. I was thinking an ls1 and then an ls2 but I am not sure.I want to try something different.

89t-top_maro

OK my camaro shakes, rattles, and DUMPS RAW FUEL out of my tail pipe bad enough that mesquitos have no chance around me. If the pollution does not kill them the loud rattles will drive them to fly in front of a Semi and commit suicide. But with that out of the way I hit around 100 at a desperate attempt to get beside one of the new challengers. It was scary and my seat is now brown.

My car just hit 67'000 mph. yep thats right 67 thou, and it felt pretty solid too, glued to the road, and i wasnt wearing my seat belt LOL

well thats the speed the earth moves around the sun

iTrader: (16)

^ Earth speed? We no need no stinking earth speed! We just hit the 88-mph mark with our newly installed flux capacitor....

zs&tas

HAHA Awsome dood ! u win i bow to the flux everytime

crytical point

137mph in my old pontiac fiero with a 2.8 and 3spd auto
160+ in my old 83 z28 with aid of a 250 shot and 450hp motor build 700r4
140 in my old 85 rx7 that had ALOT of work into it and a 9500 rev limit
about 120 ish in the 88 firebird with 3.4 but I was just seeing what she could do before performance mods.
And the fastes I have ever been on 4 wheels is in a 03 VW R32 that had a turbo, AWD, 6spd, full body kit and I went 200+ on I95 from daytona FL to Miami transporting the car for the audi dealership I worked for. Nothing shifts like a german car and haveing a 600+hp out of a v6 is really nice with AWD and being able to dump the cluch and burning out all 4 tires is nice.

firebird1992

CAPTAIN!!! SHE CAN'T TAKE NO MORE !

OK so i ran in 3rd gear this weekend and hit 110 np but she had more to give so i floored 113-117-118-126 omg and then boom i broken my transmission mount -.- guess no NOS no her this week

IROCtheThird

iTrader: (15)

I told you 3rd would give you better results I dont know why you broke your tranny mount, it was probably on its way out, when I changed mine I broke a bolt on each side of the crossmember, now I have 2 bolts on in my crossmember and 2/3 holding the mount itself in, luckily its only a 2.8, drove it like that for a while with no problems, no its off the road so I guess it doesnt matter right now, well anyway, when you fix the tranny mount, round 3, you should video tape it

firebird1992

I'm try to get the video but its hard holding a video cam when going 100+ around people and almost all my friend are afraid to sit in the car with me going that fast and the Tran mount was rotting a way -.- Im going to change that tonight and then pop that NOS kit in there 100 wet shot OOOO YEA

136 MPH in 4th @ 6500 RPM and have the datalogs..






Too bad i was on the dyno

I could have ran 5th up to about 190 but i wasn't sure how well my 140K tranny would hold up.
