Also were you on level ground or downhill. I've never tried on flat ground (there's none to be had in my area) so I don't know what exactly happens when the speed limiter kicks in. I had it up to 125 last night on a gradual hill and still had plenty pedal left, but since it was night, and I still need a new timing chain, approaching exit, only have S-rated tires, etc, etc, I quit there. After the timing chain I'll find a flat area plus the hill too and try both. I need to get the air filter isolated from the hot engine air too and see how much that helps. Still just running the "increased air intake"not "cold air intake"

So who's been to 130, someone has to have. "quiet TTA drivers"

 

myself since ive had my car ive only had it to about 80 mph. my cousin that i bought the car off from drove it to vegas and back. he said going through new mexico where there was no speed limit he said he was prolly doin 110 to 120. when we had the motor rebuilt at the speed shop the guy who bored it and rebuilt it said it was built to max out at 145. i think that was just a line of **** though.

 

YOU, being the fortunate soul, have the proper facilities (local roads & drivers) that can SAFELY handle high speed.
ME?
I was fortunate to do atleast 90-115MPH racing a Porsche (late model) on Sepulveda Blvd, thru Sepulveda Pass, one day.
We were lucky, it was clear, smooth sailing.
I've been popped/ticketed on that stretch before & I KNOW were everyone of the radar gun cycle cops hide, now.

AND THEY SHOULD keep that stretch of road speed slow.
Been several high speed head ons lately.

I did not notice a speed limiter on my ride, except myself. And I have the 85 mph speedo.
It sucks knowing that when I install the speedo head with the tripometer, my speedo won't wrap around anymore. I may use an old style speedo gear reader (like 120MPH from 1968 Camaro) in this speedo face and create graphics for the face.

 

110 on a gradual uphill incline, had plentt of pedal left tho

 

ive had 125, or so the guy says that i was flying down the highway with, i got off on his exit just to ask him the speed cuz my speedo was clock all the way over! need to get the 140 speedo!

 

I was just ealier today tacking 3900 r's downhill on the 241 tollroad near Irvine, Ca. I only have an 85 mph speedo so I ran some #'s and here's what I came up with-

12.85 tire radius/3.23 rearend /3900 rpm's/ and .70 overdrive gear= On the Equations site reads 131.9 thats downhill though. Flat lands i'm lucky to push 3400 rpm's in fourth(115 mph) without running out of room or taking too long to get up to speed.

I've done this a few times and the speedo needle buries itsself against the trip meter dial. speedo cable is starting to make some faint noises now and then. Ill have to probably replace it soon if it starts to get any worst.

I should also note that I run '87 Iroc rims on this car with Z-rated tires and the suspension is slightly lowered and fully modified as well as the brakes for safety.

 

It is great not worrying about getting pulled over, there are some stretches with like 130kph limits, but for the most part you're free, in fact you can even speed while your friends are throwing back cold ones. No open container law. As long as the driver is sober.

That and the stoplights turn yellow again when going back to green.

sorry I'm tired

 

That and the stoplights turn yellow again when going back to green.

Explain, please.
I think I understand, but....

I do like that toll road.
I've taken it once.
Was nice.

Given the current terrorist stuff going on, I'll bet my secret test track at LAX is closed now.
I don't like appearing on radar flying low.

135+mph is VERY GOOD.
Speaks highly of these little 6's.
I know the best my Wife's 1968 250 cubic inch 6 Cylinder in her Camaro did was about 95mph (after I got my hands on it!).

 

Ive takein mine past the 110 mark to that peg to stop the needle from movieng any more and i was at 6500 RPM WAs haveing fun on the 118 at 3am.

 

My 1992 3.1 liter will only go right at 120 MPH, which is about 195 Km/hr. When my needle just crosses the 120 mark, the speed limiter kicks in and drops you about 3 or 4 MPH. I have done this several times in my younger and more foolish days. There really isn't anywhere around here that you can do that, except maybe on the interstate, and then you run the risk of getting busted and visiting the crossbar inn. I was still gaining speed when I hit the limiter. I imagine my car could get up to 130 or so if it weren't for that.

 

I've had mine up to 115ish until I started going up this big hill. I've only done that once just to see how fast she was, now I usually get up to 65 for saftey reasons. There are lots of old people here that will pull right out infront of you and they will not get on the gas to speed up. :angry:

 

Stoplights over here, green-yellow-red-yellow-green

In the states, green-yellow-red-green

So at least half the time yellow actually does mean 'step on it'.

 

i've been up to about 120 maybe dunno, i wrapped the speedo back around to 20+, (i have the 140km/h speedo)

 

137 mph... I was racing a VW turbo passat in upstate new york, going to a campsite with a buddy. Hell of a race... never saw a car pull like that thing did. (Didn't know it was turbo while we were racing.) When we hit traffic, we slowed down, and my buddy saw him waving a CB microphone at me. I picked up my mike on 19, and we were talking about the race- He said I was the first Firebird that he could beat! So I quickly, to save the face of every other V8 TPI 3rd gen, mentioned I had a V6- and that surprised him. So I asked what he had, and he told me a 4cyl turbo, which suprised the hell outta me. So we were talking about the race, and he said something about speed, so it hit me.. I asked him how fast his speedo went, he said 150 or so, so I asked him how fast we were going the last time we lined up. He said between 135 and 140... My friend and I did the speed limit the rest of the way. Can't believe we did that on 112mph S-rated tires!! I think I skipped the speed limieter by one of two ways... back then, I had the ADS chip in. I also had P255/70r15 rear tires, which lowered my effective gear ratio, and slowed my speedometer down. So for whatever reason, I didn't hit any speed limiter.

I tell ya though, I've never gone that fast again; and don't quite intend to.

 

I dont think the 86 had a speed limiter???? dont know, ive had mine burried for 4-5 miles holding it wide open on the e-way. dont know how fast i was goin but the punk in his z24 was way behind.

Course it why I win most e-way races, Ill holds it wide open for ever if I have too. My wagon is even faster on the e-way, but a big *** slug taking off.

 

He told you a tall tale. My car is geared higher and is in spotless condition inside and out, Lowered areodynamically, and the suspension is rock solid race components. I was going downhill (fairly steep) and the motor would not push the car through the air any faster than 132 Mph! He was B.Sing you. ( I have driven my Vette at 165+. But that puts out 540 hp and gets up to speed and back down before you have a chance to run out of road)

 

I've been pondering getting new tires. I only have S-rated too. After the timing chain I'll probably be driving faster, testing out the top speed, and whatnot. And believe me, everytime I get above 100-110, all I can think is, "damn a blowout would suck right now"

 

I always wondered about that... but I don't know why he'd lie to me.. oh well.

I can't even get higher than S-rated with the rear P275/60r15's. It looks like it's something to do with the aspect ratio... the higher the aspect ratio (height), the slower the tire has to be rated for.

 

awwww you're no fun :lala: :sillylol:

140 and still had more to go

 

Im pretty sure ive hit at least 140 I was accelerating for 5 mins but i was still gaing speed i hit 6500 rpm.

 

My V6 is only my grocery getter! I can break out the heavy artilery for comments like that

 

Wait til my firebird runs the guy shuld be starting the body work tommorw the car has been in his shop over a year he seemd kinda pissed today since i havent talked to him about the car since 6 months ago. IT has a 400 in it and its bone stock right now down to the factory coil everything that was replaced on that car was all AC delco OEM or oer parts. I cant wait to see what that car will do once i get rid of the drum brakes in front.

 

This is intented to help you, not ridicule you;

Print out a copy of what you just posted and then read it 10 yrs frrom now. Do you think that sounds like a wise and accurate thing you just posted. 10 yrs from now you will be embarassed to look back at that comment, I promise you. These motors will not do 6500 rpms. And especially not in fouth gear (stick or auto). You probably wont like me for stating this but you need to realise that you can't bullsh*t the people that have been there. Sorry

 

I dont have to prove anything to any one i know it happend and so did my friend thats all i care. If people dont belive me then let them not as long as i knwo it happend thats all i care.

 

whoah whoah 6500 in WHAT GEAR doing 140??? i was at like 4500-4800(i think, i can't remember, i might not even have been as high as 4800)

 

Had my wife's V6 to about 115... Her motor is dead now. Time for a swap....
Maybe something like mine....
She said I could use it for a project car.... *WEG*

 

i was in drive had the it flored the whoe time

 

I have taken my Camaro to the speed limiter several times. Not sure how fast sence my gauge only goes to 110MPH.

 

O.k. I'll help you compute this one. What year car do you have? And is the Transmission and rear axle stock? Also what size tire do you have (i.e--245/50-16, etc.)? Were you in drive or do you have an overdrive?

 

i have a 91 Camaro with a 3.1. The trans mission has been rebuilt to stock specs. The rear end is stock with 3.23. I have 15 inch rims with 225/60/15

 

Were you in overdrive?

 

drive

 

Wow buddy, you camaro should be in the guiness book of world records-- You were doing 153mph flat!

 

I said 140 because you have to take into consideration wind resestiance. And im more then welling to prove it to i got bashed for this a while back when we had a post like this and like isaid then im welling to prove it jsut as long as no cars are on the freeway when i do it. YEs when i speed i make sure no ones around.

 

So now you are telling me that even though you were turning 6500rpm's the wind slowed you down to 140 and not 153?

You did say you were doing 6500rpm's didn't you?

 

yes i did. I was guessing 140. If our cars were perfectly aarow dynamic and had no wind restence then yes i would be doin 153 but you have to take then your going that fast there will be wind.
Take your car to 70 on a day when its not windy at all roll down the windows what happens you have a wind like effect in your car when the air is blowing at you in your face.

 

Let me explain to you how stupid you sound, I obviously have nothing to do right now and I'm having fun:

When you are doing 6500 rpms in third gear with your set up, the car will do 153mph and thats it, not 145 not 160. Wind has no variable as to speed from rpm. If you were only doing 140 because of wind then you would only be able to turn 5935rpm's.

(I had to stop and laugh at my last sentence. the word ONLY)

Either you were doing 140 or you were doing 6500rpm's. You can't do both.

Conclusion is: You are not certain

Go fu(k with someone else moron.

(turn to the Judge) Your Honor, If it pleases the court, I rest my case.

 

I think i will go do that with my G/F. I Was doing 6500 RPM So then i was doing according to you 153. Im having fun laughing at you cuz i know and saw what i did. I just find it funnythat your arguing over a flippin computer.

 

BTW in A older issue of hot rod they took a new camaro and a new trans am to the track the camaro was slower then the firebird they claimd it was from wind restence and different aarow dynamics.

 

camaros have them wind jammer headlight, which has to really effect top speed. at night i bet a camaro ta/firebid would be about even.

he could be doing 140 at 6500 with TC slip, tranny slip or anything else in the auto slaush system. wind restance could effect an automatic.

 

5935 vs 6500 RPM so we're arguing about 565 rpms?

I swear some people on this board just can't keep their mouth shut. Okay so he is off in the calclations. Ever think he was reading off his original tach (of which is OH SO RELIABLE)? Instead we need to get into some scientific/mathematical pissing contest to see who was right.

Given the fact that you calculate he was going faster than he claims, I'd say let the claim stand.

 

I know for sure if he has the 2.8/3.1 that car was not going uphill! If anything it was going downhill with a huge wind behind it, say 50MPH?
It's very hard to believe. I do believe around 115-120 on level ground or downhill is possible with it. Pushing the engine past that point is just crazy.
Like I said, I used to have fun running over the mountains with my wife in her car, and myself in mine...
She had a hard time getting the car to go over 80 uphill... I would just fly right by her. (That was when I had the 305 in my car too!)
She just would get mad, so I would just back off and let her come close.
The claim of making the 2.8/3.1 go that quick is hard to imagine.
I guess it's possible, but you will need a long straight downhill....
That's my opinion.

 

So now you are telling me he did 140 with mechanical problems?

 

You obviously have a V6 that will do 140 and tach 6000+rpms in a high gear also. Some people are so naive.

Some other people on this board need to learn to keep their frikin mouth shut too.

 

Just a couple of things.... Unless FastRS has done something with the computer, there is no way that car hit 140 MPH. I have a 1992 3.1 Liter automatic, and it will go right about 120, and the speed limiter kicks in. This was verified by a buddy in a Corvette who was behind me. That being said, if he has a chip or been reprogrammed or something, then I believe that it is possible to get the car that fast, especially if he lowered it or has some aerodynamic mods. I can make mine shut off pretty easily, and I believe that gaining another 15 to 20 MPH wouldn't be unachievable, especially if he was running with his foot to the carpet for a while.

I understand what Friggin' is trying to say as well... That the engine couldn't actually be turning that RPM with that gear at that speed. Could have been either the speedo or the tach off, could've been anything. Who knows... I don't think I would be looking at the tach too closely if I was going 140, either.

Can the pissing match now end?????

 

Yes i have a fast chip stage 2. Here are my mods CAI, MSD 6al, MSD coil with MSD wires Rapid fire plugs, High flow cat, Flowmaster Exhaust, Power Pullys, Ported Heads, And a kinda new tranny. I know i have 1 other mod but its not commin to me right now

 

Sometimes it is fun to watch two trains collide

You'll have to give me a ride at the 140 mark.
Is that downhill to Simi!

Thanks for confirming the 118 is my new test track.

I'm to far to drive to LAX test track anymore.
When I upgrade my suspension, I'll try another high speed run.
I just want to mod my 1985 mechaical speedo so it can read to 160 MPH.
Maybe I'll use the speedo guts drive from the left over 1969 Firebird stuff I have!!
I need to find another old 1968-78 Corvette speedo.
They come with factory 160 MPH speedos guts too!

YEAH!!!!!!!!

 

If you do it do it around 3 am if you see a car 99 percent chance it will be a cop so u know to back off. There is a strech between madea to new la ave about 5 miles with no on ramps so if there are no cars go for it also the same in the valley except you have on ramps with the chanch of a cop gettin on. Ill take you for a ride one night and prove it to you.

 

I have only had mine to 110. It was running smooth, and i had pedal left. I only did that once, probably won't it again. Too many things can happen on the road for that to be safe.

 

guess you can consider me your prime example then, VA = I-66 doin 120 before i eased off, still pedal left, and still rpms although i don't know how much...... that was also about 1.3 minutes before the fairfax sergeant pulled me over. what a nice fellow. thankfully, he only gunned me at 87, so that was only 12mph over reckless, and $75 fine and a point or 2 on my lisence later, i've decided to keep it to the track.

i'm assuming there IS a speed limiter for the stickshifts, i didn't feel anything, but you guys have only been talking about autos, so i'm curious......?
