It does kinda suck on the highway (3000 rpm @ 65 or so). I actually don't really know how fast im going cuz i didn't adjust the speedo. I estimate my speed by 3.42x(speedo)/4.10 or just multiply my speed times .834, so if my speed says 100 im really doing 83... Im running through the traps at 114mph @ 5000rpm so im guessing 120 top end at 6000rpm.

One time I had to drive to the opposite side of michigan for a concert, on the way home I just wanted to get back quickly (it was like a 4 hour drive one way) The road was clear, so I gunned it, I started off going about 90 and before I knew it, I burried my needle, I was quite surprised, didnt really even feel that fast, but yeah, it felt like I was floating, really cool sensation. I was going probably 150? I still had some power left but it was stretching it out pretty far.
In my friends mazda speed protege we got up to 140 faster than flys on ****. that was hot.

Going 150mph is pretty impressive. Your car must have more than a stock motor to do that. With the right gears i think 250hp is capable of 150....

Just a crate goodwrench 350 with headers and thats about it, poorly tuned ccqjet and bad timing, haha. Pretty much stock as far as the upper end goes, but the 350 is probably why I was able to go that fast 
cant wait till I get a better job to get myself a nice new intake manifold/carb and maybe a new cam.
I dont know which rear end gears I have, when I bought the car the guy figured they were stock.

Yeah, i bet you could get 150 out of it with the long legged highway gears. Thats kinda scary though. My car feels like the space shuttle on re-entry when i go over 115. My car is set up for maximum 1/4 mile. It would be cool to set up a third gen for top speed. One mag i read says the third gen is one of the most areodynamic production cars ever made. They said 200 mph is achievable with like 450hp and 2.?? gears and a 6 speed manual. we got too many hills and curves around here to go that fast...

200mph haha thats friggen insane, but yeah, it felt solid and didnt shake at all, i was probably going with the wind and it was a straight away when i was gunning it. My old cars would shake going past 100 but mine didnt so thats why I kept going further, I forgot to mention that, thats what surprised me the most.

man your engine bay looks so clean especially for 140k miles. I have 147 on mine but only 40k on the engine and trans. I want to get nos, but I have to save up some money first for the intake and ****.

I have nothing bad to say about the spray. Everyone said i was gonna blow that stock motor up shooting 150 HP through it.... That has been 5 years ago and 21 refills on the bottle... I don't even retard the timing, i may be retarded for not doing it....
I think it would be cool to spray a 150 shot on a car with tall gears and see how hard it pulls from a 100 mph.

I think its kinda crazy to go faster than 120 on the street anyway. If you got the space like in Montana it would be cool. I got stock brakes with drums in the back

I bet you 30 dollars that you can reach 120 as long as your ecu doesnt cut you out. my sisters cavalier can reach 110, and would still go but the ecu cuts out *BAD CAR COMPANYS, BAD!"
I've gone 120 on streets before, not something im proud of or anything, but if I ever do anything stupid like that I make sure there is NO traffic either way, and I turn my brights on just for good measure.
oh yeah, yesterday... wow...
srt-4, at the light, right in front of me, he's reving his engine, must have had an aftermarket wastegate, HOLY CHICKEN SHI T THAT SOUNDED SO NICE, like orgasmic or something. Well anyways I rev my engine a little bit, light turns green, he doesnt take off TOO fast but just enough to get ahead of the traffic next to him so i can get up there with him. Once im next to him we both gun it and he is SLOWLY pulling away. I was like WHAT THE HELL WHY IS HE SLOWLY PULLING AWAY I AM NOT SUPPOSE TO DO THAT HE IS SUPPOSE TO GO FLYING PAST ME. I got next to him at the next light and hes like damn man what do you go in there, and im just like eh, its just a 350 with headers. He's like yeah I did a lot of work to mine so far, im surprised you kept up the way you did. Im like yeah thanks, and then hes like "where do you buy those kits to make flames shoot out your tailpipes" and im like hahaha, my timing is too far advanced, and hes like oh haha and yeah then i turned and he went on his way.
In fact since a timing gun at autozone is 30 dollars and it costs 35 at the local shop to get my timing done, im going up today. Hopefully ill see a performance increase with the proper timing and better gas mileage.

I hit the wall at like almost 115, at 4500 rpm in 3rd, and again at less than 3000 rpm in overdrive... didnt get to disable that damn speed limiter before it got wrecked. but cmon guys, 170? thats hard to believe. I mean I know that we have very aerodynamic bodies, but no stock thirdgen is gonna be stable at those speeds. I doubt it would be stable much over 155. cruising at a buck 35 would be nice though... Anyone have a car thats set up for high speed runs? what gears do you use? what tranny?

I was on the 118 Freeway, coming right off the 210, early last Memorial Day morning and the freeway was clear, so I decided to lean into it and see how fast I could go before hitting "cop alley" (ie the part after the Interstate 5 interchange).
By the time I hit the 5 I was up around 115 MPH (I was playing it safe and listening for any signs of problems, so I didn't accelerate that fast), and the engine was only around 3500 RPM. Still had power, but I didn't want to have to explain to the friendly neighborhood CHP officer why I was doing 120+ in a 65 zone (ow).
Of course right now the engine is slightly detuned for performance and more tuned for economy (damn fuel prices), so I don't really punch it much. I really should get a set of 2.73s and find some lonely, straight road out in the middle of nowhere I can test it out on. It's kind of annoying that my gearing right now means that I'm going about 3000@90MPH.

damn, whtas inside that talon to make it run 11's in a quarter mile, thats really really quick.
Just a T3/T04B turbo, an intercooler from an Isuzu delivery truck, 3" exhaust, fuel support, tuning, and 23 psi, that's the basics anyway. It's AWD also, I was getting 1.7x 60's spinning all 4 through first on worn out 225/45/17 Dunlop's. Otherwise it's still a bone stock 2.0 from intake mani to oil pan.
11's aren't all that out of the ordinary anymore, really. There are plenty of street cars around in the 11's these days. :/ It does make my slightly modded IROC feel really slow though.
There was a clean black LS1 Z28 that day that I saw run an 11.1, then I saw him drive it out of there.
Didn't get to talk to him because I was so busy with my car, unfortunately.

hahaha where the hell did that come from? again, for no reason, the Vette guys get bashed. so, according to you guys, i was a ***** cause i didnt break the speed limit every chance i got during my 6 years of Corvette ownershipoh wait, there was this one time i had my old 89' Vette up to 124mph. ONCE. scared the **** out of me. never again. could you imagine if a deer walked out in front of you at that speed? waaaaay to dangerous. but maybe youll guys will understand when you mature a bit

Its not just you, but seriously, anyone who owns a vette drives so *** damn perfect its sick, I NEVER SEE ONE GET IT ON. well except for once when I had my sisters 03 cavalier and I was ****ing with him, those ecotechs are pretty peppy, but in no way compairable to a vette.. But seriously, I've seen more vipers nailing it than I have vettes. That has got to say something in itself.

Why purchase a machine that is capable of so much if you are only driving it so you look cool/rich/whatever. Fast cars are made to go fast, even if its just flooring it to the speed limit once and a while to feel some pull.
Its not like all of us drive around at like were racing every day.

To the guy with the V6 Mustang, it doesn't really matter what size motor a car has. I've gotten all of the Acuras I've owned up to 130mph.

if anyone is still bent on Vettes not street racing, please feel free to visit this site. there are plenty of Vette owners here willing to run: www.corvettekillstories.com

115 till the ECM cut out. Traffic moves 90MPH all the time here if you know where to look. I was already doing ~95 and wanted to know if my car had the speed limiter. Now I know. Felt strange when it kicked in. Engine got really loud and the tach jumped up about a grand. Engine still had a decent amount of power right up until the ECM cut it. I'd say 135 is probably my limit for any normal stretch of road. It's just a slightly modified L03 w/700R4 & 2.73s.
I've driven my bosses Mercedes E500 and I must say *!YARGA!*
One thing: I've heard that fourth gens have a speed limiter, but that it won't bring the engine back up until you key off/on from a stop. Is this true?

its possible but he needs alot more power and a better tranny, then some some gears, I know there are guys going for 300mph in an late 3rdgen firebird, but nothing is stock and they are playing with the body length to try to get it to go faster.
If he has a camaro, then he has the upper end advantage since the intake is more of a ram air style. If he has a firebird he doesn't gain any high speed highpower do to the airbox.
