How fast? Is the Quistion

How fast can u guys get your birds going give it a post if u think its worth posting!

I can get my 67 about 163mph and i can get the 95 going 154mph the 02 i have been told is EG at 155 but not sure

after i put my 400 in it,itll be going pretty gosh darned fast lol

My top speed is said to be around 168 MPH.

My fastest......about 130, right at the top of 4th.

I have a '77 with a 100 mph speedometer, i've had the needle come back around to about 5, i dont even know if the speedometer is still accurate at the speed, but if it is that should be somewhere around 150 or more.

If anyone knows how fast that really is please let me know.

135 here, and rock solid all the way through, no shakes or rattles... oh yeah :)

The fastest I've ever had my 97 was 145, felt solid but I'd still rather not do it again.

the first day i got my 76 home me an my dad took it out and i had it at like 130 until i seen the smokey so i had to let off the gas haha... that was its first time runnin since it was sittin for 6 years on a farm

Wow thats fast guys.Good thing no grandmas with shopping carts stepped in the path

174 according to my friends grxr750 it took a while for me to get there and i will do it again. this car will be the death of me. thats why im getting the roll cage

my 79 ta has been clocked at 230 on interstate 40 but she did the what lane dance on me and i back out the throttle at about 5000rpm with a limiter at 7000 i have a little more. oh yeah the cop let me go

um...im calling BS on the 230 cause radar doesnt even go up that high on metro police cars or highway patrol cruisers.Sounds like a bunch of guessin to me.Do any of you guys have proof,not to call anybody a liar but common dude 230?What motor and rear ratio?Thats like federal mogul speed/I spend a lot of time at race tracks and have worked at a few,and currently have VIP pass to several and you cant just say"yeah man im driving a funny car on the street",and people believe you

pfff... yeah guys, once in my bat mobile id did mach II...... but that was only with the after burners going and because i put the NOZ on her.... it was just like they say.... once youve gone bat... ya aint goin back...

I don't want to offened anybody, but for the record. I never said in a quarter mile. my car takes a minute to get goin'. With a custom geared richmond 6-speed tranny and 2.42 rear gear with a 30 inch diameter tire all pushed by 502 flywheel horses it goes. By the way there are a number of radar systems out there that are capable of reading up to 999 mph. such as the KUSTOM HR-12, KUSTOM Pro-1000DS, DECATUR GENISIS 1, and not to mention the entire line of MPH Radar systems.And as for drivin' around town i only do that once maybe twice a year, she lives on a trailer most of the year.

November, 1979. '77 T/A, 403 with some "enhancements", 2.42 gears, TH350, 2.55/60-15 Radial T/As, 6,400 RPM. Works out to around 180 MPH. We were on I-15 going to Vegas. A Ferrari (like Magnum's) wanted to play. Ferrari driver backed out first!

the stock gearing on an m6 lt1-ls1 will get you to 255. you just need the power to get there. i think you need a little over 800 whp with stock aero's

164= factory top speed of lt1 in 5th gear (road and track)
160= top speed of ls1 in 5th (speed limiter)(friends car)

I didn't hit 180, probably 150-160 at most over the course of the trip; this was later on, on the I-40.

I also played with a bunch of cars, only two that went the distance were a '96 BMW M3 and a 2000 Firebird T/A. Countless amounts of Mustangs and Grand Prixs.

"Enhancements" were no form of emmisions equipment and an exaust unattached after the headers.

hear is the gear website. its kind of neat to see what little things like tire size and rev limiter increase will do for your ride

LT1 guys...156ish is your stock limiter
LS1 guys is 163mph.

I know...I used HPTuners to remove mine. 300 mph :grinno:

But seriously, in NV, I had my car going well over 160. When the scanner and speedo said 160 for a few seconds after I let off the gas and then started coming back down...we knew we were haulin'....of course the 750 bike didn't like it when he thought he would walk me and didn't. :biggrin:

Well I've heard those numbers before they sound believable

But what about Mr. 230 mph on page 1? He says he can go almost twice as fast as you.

I would love to see the super-duper tires he has on this car to withstand those speeds.

230mph eh? I hope that bird has landing gear because when it starts flying in the air you're going to have to come down sometime. I'm not saying it's impossible..but that would be some kind of record. Not to mention if you get pulled over going 230mph..they're not going to let you go. Not to mention they'd 'catch you' like 5 miles down the road. Because they'd be at a stop..and you'd be going 230mph past them. And that's just if you decided to stop. You could easily keep going and they'd never catch you. I'm reaching for my BS flag...

LT1 guys...156ish is your stock limiter
LS1 guys is 163mph.

93-95 cars with non z rated tires and an older PCM calibration were limited to 108 MPH and received a 110 speedo.

94 and 95 cars had a newer calibration from GM which raised the limit to 118 MPH.

93-95 Z-rated cars all had the speed limiter set to 255 MPH.

96-02 F cars with non z-rated tires all had 118 MPH speed limiters.

96-02 F cars with Z rated tires were all limited to 160 MPH.

thier is no 154 speed limiter

In theory, you could go 2xx in a TA...but you'd better be pushing some crazy HP....a few Thousand should do. Or drop it off a 1/4 mile cliff.

People like that crack me up :rolleyes:

thier is no 154 speed limiter

Z Rated tired cars were 15x(LT1s) and 163 LS1s(this is fact from all the programming I have done on the 98 cars)

I didn't talk about non-Z rated tires. I know some were 108..but not sure about the others.

NO way that GM allowed the zrated tired cars in 93-95 a 255mph speed limiter.

it wasnt in a firebird, but I have got clocked at 143mph in my 95 camaro (V6) last year, i dont know what the top end it tho my spedometer doesn't register past 120, i was slowing down when he clocked me...that ticket sucked...
-Dustin (NC)

I would love to see the list of mods you had done to that v6 to reach 140+. I wouldn't post um in the forum though you might cause the sight to crash.

Or was it some kind of rear end gear swapping? 0-60 in 3 mins?

Or maybe its because you haven't realized yet that there is actually an Lt1 in that camaro.

I'm not trying to blast you but I've been behind the wheel of the 3.4 and 3.8, and in the highest gear they are struggling past 110.

I've been told by a person or 2 with 95s (OBD1) and they said when they looked at the limit in the PCM it was set to 255, which is the highest value you can set it to because the PCM uses 8-bits to hold the data which gives it a range of 0 - 255.

here is the only 255mph car ive seen lately.Not calling anybody a liar or nothing,but a federal mogul dragster is the only thing your going to be catching hanging out at 255mph.This is a picture from last seasons federal mogul bracket races here in oklahoma at thunder valley.As you can see i had a pretty good seat to the show.

there is no way 230 the cop would of busted your @$$ in a second my freind got a tickket goin 150 in his custom talon and lost his licence

I had my freinds 6 speed 94 going 155.

yeah, a "few mods" if you wanna know what all is done to it then email me, i'd be happy to send you back a list of everything that is done... and if that isnt enough then i will gladly photocopy the ticket that i got and send it to you, i hate being called out like that...and i never said that i got to 143 in a quarter mile...and no - there is no LT1, its not a Z28, or SS... its a 3.4...with a "simple" 4L60 trany behind it...

Neither am I when I use the tuner kit from www.hptuners.com and download the values(all the values) to every table known to man in the LS1 PCM, you can say I know better then another website. I've only done 1 LT1 and it was his LT1Edit program and cable and he already did his top speed/gear/tire changes, so I did not have to get into it.

Nice pic! I'll be heading through OKC in about 2 weeks and isn't thunder valley near Norman?

hey my 95 3.4 with little work has no trouble sending the speedo past 115 witch is the highest it will read fastest ever clock was 90 so dont know exact i fig. on a good day with about a mile of road i could get about 120 out of it but dont trust the tire vibration i get at over 110 only maxed it once got scared no land speed record but i think is pretty fast for a 3.4 with stock drivetrain an wallmart tires

the tires a great for this thoughttp://files.automotiveforums.com/gallery/watermark.php?file=/501/280513post-med.JPG

hey 86ta just interested in some good mods what is yer email

Exit 108A in norman, (Hwy 9 east) 5 miles. Take Hwy 77 South to Noble, go through Noble (watch speed limits). 2 miles south of Noble turn right on 48th Street. This dead ends into the track.http://files.automotiveforums.com/gallery/watermark.php?file=/500/260330thunder_map.jpg

If you stand at the very end of the track and watch those cars exit a quarter mile doing 255 MPH,as you watch them pass by you will know you havent gone that fast in a street car.

My email is [email protected], if oyu got aim my sn is momma goose140...

hey 86ta just interested in some good mods what is yer email

This is my 79 Firebird... shes got an olds 403 with a holley performer 4 bbl carb, and a turbo 350 automatic tranny. I think... I dont know much about the car cause I got it from a police auction with no history... but I do know shes fast... Ive had her up to a guestimated 140 something, the spedo goes to 120 and it was buiried pretty nice.. I thought i was going to die though... the car sounded like it was going to blow apart at any second... I'll probably do it again anyway :smokin:

look at firebird v6 .com
