If you don't consider SLP Firehawks stock then a stripper (1LE) 92 Z28. 92 motors had the hightest HP rating. I understand a 305 1LE with 5spd is pretty close to the 350 auto 1LE. Depends on the driver I'd guess.

The fastest road test i've ever seen was of a 1990 L98 IROC. I believe it ran a 14.4 at around 98mph. I also remember Car Craft wringing some great times out of an '89 or '90 IROC 1LE car. If you where to line all the different models up I really don't know what would come out on top. It would probably come down to the 1990 IROC's and the 1990 Formula 350's. Just my opinion.

I'd have to say a 91-92 Firehawk. Those are BEASTS

Jasper89ROC

Any one ever heard of the 12 made LT9 '89 IROC's, fastest stock 3rd gen i know of.
Oh yeah 450 hp I believe, and may be of 9 made I cant remember.

I've never heard of that before. There are many L98 Third Gens out there running 14.1-14.2, usually IROC-Z's and the Z28's.

I remember reading about a limited production run of Camaros, made in either 91 or 92. These cars had a miniram style intake, I guess that would be the LT1, and Corvette ZF 6 speed transmission, plus all the 1LE suspension goodies too. Horsepower was way up there too, a helluva lot more than a stock LT1. Apparently Chevy built these cars to showcase its ability to build a sportscar that could compete with the finest in the world. Too bad they never sold any of them to the public. FYE, most of these cars, like other test mules, were sent to the crusher.

Wouldn't the TTA be one of the fastest stock 3rd gens ?

Guest

If you dont want to count the TTA, why even ask?

HAHAHAHAHAAH Oh my, thats funny.

Ions91Z28

He may be looking for car he can afford... those tend to be a little higher in price. Or maybe he likes the sound of a V8. Either way, I'll stick with most any L98. SD Version. Most will pull a 96-98 MPH trap speed.

The 91-92 Firehawks were by far the fastest. The Stage 3 option Firehawks with the aluminum block and heads were top dogs. Second were the 89 Turbo Trans Ams....

Jasper89ROC

Alright dumbass my buddy used to own one, just cause u never heard of it doesnt mean it never existed.

nblanchard

I was told the fastest thirdgen from factory was the TTA.... I don't know if I would consider firehawks factory, just cause it has SLP stuff on there.. the TTA had everything from GM... I dunno, maybe I am blowing wind out of my a$$... but I was always told the TTA was the fastest F-Body made.

Earl 87gta

He said other then then the TTA the TTA is the 89 Turbo TA. But I think I remeber reading of a gm project car that had a big block in it in a mag once but dont remeber much abought it.

Guest

Really? Give me proof besides your friend of a friend story. Pictures, documentation, etc. I've been into F-bodies probably longer than you have been alive and have heard more BS stories about wild 'factory stock' cars than I can count.

Jasper89ROC

I well get that stuff for you, I can get proof that will shut you up. I just talked to my buddy that had the car. Hes got pictures, documentation and possibly even the window sticker
HA I win!!!

Guest

We will see about that. Dealer add ons dont count.

Jasper89ROC

I didnt see ne thing about dealer addons not counting?? When I get the stuff I will make a new post incase this one isnt here any more. It will take me a few days, my buddy lives a while away from me. But you cant deny it soon. LT9 H.O.w/ 400 some odd hp

Since when is a car that is modified after it leaves the factory stock?

2QUIK6

Anybody know what the 91-92 Firehawks run stock and how many built?
FYI, the TTA wasn't finished at a GM plant, but rather PAS did the motor/tanny install, 1555 total built. Also, if you look hard enough, you can find 80k+ mile TTA for less than $10k, hell I got mine for $15k and it only had 5300 miles on it. It ran 13.3's all night stock.

How about the SLP performance package cars you could have gotten back in 91/92, I think it was a dealer install option that you could have ordered that came with SLP's cat back, headers, chip, and runners.

HM Murdock

Yup, I know a guy personally with a 91 FOrmula SLP 350, ordered with the SLP T-Ram from the dealer...He lives in Florida, and is a constant poster on SLP's message board(he also owns 2 Firehawks..a 99 and an '02...

I think Jester is talking about the Firefox. They had IRS and all sorts of other fun stuff... and i think they were around 400 HP with twin turbos. They never came to be but would have been the basdest thirdgen out there . I believe the TTA was the final product from the research. No one owns one... they are locked up safe and sound at GM

ploegi

At one time, GM built an LT5 Camaro. (yeah, a 32 valve V-8 in a third gen...... damn....) There was only one, and I think it did the car show circuit for a couple months in 91. Then it was "retired"......

Now THAT would be an interesting ride.

91-ZZ4-Z28

Jasper89ROC I think your friend is full of ****

CraZ-28

The LT-5 Z-28 is still around. I saw it this year at the Super Chevy Show. One bad Z with One bad price tag...............if it had one!

JAYDUBB

Actually, I think the car youre refering to is the "never to be built" 25th anniversary Camaro. White with black stripes. More than 300 hp (350 maybe?). ZF 6 speed. I think it was a low 13 or high 12 car (dont remember). They didnt want to buid anything faster than the 'Vette (well, thats what I think) so they cited "cost" issues and never built it. Those dumb asses know that the damn car would've sold like hot cakes. The Impala sold! Hell... the ZR1 sold! And the IROC sold (they were supposed to be limited production too).

88irocz28

Yes that is the car I was talking about. I couldn't remember then but now that you mention it it was the never made 25th Anniversary Camaro. Man, what a blast that ride would have been. 350 hp, 6 speed, plus all the suspension goodies and one mad motor. It was available only in white and the rims were black crosslace rims originally offered on the GTA.

2QUIK6

Not sure if that was the reason or not, heck they built the GNX and TTA which were faster than the Vettes of those years, but they advertised the hp rating lower when it really wasn't....I don't know what GM is smokin, notice how they pulled those TA TV ads a few years ago...think they were afraid it would start selling good and out sell the Crustangs, then heaven forbid GM could not convert the f-body factories to make SUV for some a$$ to drive around with their cell phone crammed in their ear.....
Just letting off a little steam....this in is fact one other example of how GM isn't even trying to sell sport cars and compete with Ford, oh well, it'll make the Ford boys happy because the Mustang will soon be the "fastest" in its class because there will be no other cars in its class to complete

Yes but the Vette did have the B2K twin turbo as a factory option(Callaway) in 89 that was on par with the GNX and TTA.

on par with them?i don't recall chevy ever having a deal with callaway cars to produce tt vettes.especially in 89 since the zr1 was in it's first year.everybody knows or should know th fastest factory tuner car even today was the corvette callaway sledgehammer(1989)254.76mph/10.01 in 1/4.the fastest factory 3rd gen(factory meaning right from the assm. line was the 89 1le 350 auto,14.17@96.56mph.all others were produced or tweaked elsewhere(89tta-asc mcClaren)(firehawk-slp)etc.

67 Camaro 88

What about this? Never heard of this think till I saw it looking around for some GTA stuff.

Its the Firefox at the bottom with the pic. Ran a tested (which is usually low right?) 13.38 Qmile. 4.10's ... says in that little text part there that it was actually faster than the TTA "(and in some cases, surpassing)"

Just thought Id throw that out I bet you cant find one either tho lol

it is a tuner car,the base platform was developed by gm,then a performannce outlet put their mods on it.you couldn't go to your local gm dealer and order a firefox.you could order a firehawk though,but the mods done to the car were performed at slp's shop in Tom's River,NJ.

Acceld Z

RPO B2K was offered by Chev from 1987(?)-1990. I think it was sort of the same deal GM had with SLP. The first year the ZR-1 was available to the public was 1990. The SledgeHammer was a monster Callaway has an article on the car at www.callawaycars.com if anyone wants to see this thing. Those numbers Pete quoted are not a misprint

poorboy8

FYI: My 91 GTA completely stock ran a best of 14.3 @ 96mph!

91-ZZ4-Z28

PETE:
PRO B2K was from 1987-1989 and was a 19,995$ option on a car with a 21,500$ base price, they were built in the normal Bowling Green KY plant and then shipped to Callaway in Old Lyme CT for the turbo install and tuning then to the showroom. They made 350HP in 87, 382HP in 88-89 and the option went to 25,895$. A TH400 auto was a 6500$ option and made it a 53,895$ car in 88. But it did go 177mph. They made about 450 of them over the three years.

nblanchard

I don't see any info on the PRO B2K in the callaway website... can someone point me to some more info on this car?

Bill's86Vette

I wanted to suggest something I read some years back about the anniversary/or special editions Camaros that never made production.They were rated at 275 HP,not 300-350.And was there was a 6 speed planned.

I read this in Car Craft or one of them magazines some years back and the reason GM pulled the plug on them is because the economy was very slow and the price tag was very high and they predicted they wouldnt sell those cars enough to justify the cost.
So you got stuck with badges and stickers instead.
I was working at a Chevy dealer back in 90-91 and sales were so bad we had very little work in the shops too.Not too many young people could afford them cars and the insurance.(like me)
I wanted a 5.7 Camaro/or GTA and my payments alone on the insurance wouldve killed me.
DId GM learn anything? No..and with the increasing prices of the 4th gens,they stopped selling and pulled the plug.
Ahh it was nice to dream eh?

No5.0

My 88 formula was a very fast example of the 305 tpi 5 spd/3.45 ws6 variety. In my opinion the gearing/trans combination would give a big advantage over most of the other f bodies(including l98's). I personally enjoy manual shifting cars, gear ratio is one of the most important aspects of rolling down the road.
BTW the 89 TTA was the fastests fbody from 73-97 with only big block 400's, lt4 and ls1 able to compete.

question, WTF is a LT9 H.O. engine

Grim Reaper

A schoolboy's fable. No such engine from GM.

Raptor Pilot

First off, the LT9 does not exist except to the people that make up their own engine code designations, and them slap a sticker saying LT9 on the fenders. The TTA and the Firehawk, in that order, were the fastest 3rd Gen cars out of the box. The Firefox was built by TDM Technologies in Livonia, Michigan, and put out 328 HP and ran the 1/4 only 2 tenths slower than the 91/92 Hawks. The first Firefox was Black with Twin Turbos and the last one was a 91/92 with Jade Green Metallic paint and A/C delete with a Corvette IRS and 17" BBS wheels.

Second, I hate how people always reply on boards or write articles in the major auto mags and always refer to the "Camaro" an not the Firebird models...example "what's the fastest 3rd Gen?" answer-" the 92 Z28 Camaro." Hello!!!!! How about saying "The 91/92 L98 3rd Gens" or "The 19XX Bird/Camaro" I understand that some have loyalties to one car or the other most of the time, hence they are your preference, but you can't always leave the other car out. this happens 9 out of 10 times, and it is a pet peeve of mine. I just want equal recognition.

I would say besides the TTA and SLP T-Rammed Firehawk, (which are both very hard to find, trust me) then the fastest would be SPeed Density 91-92 L98 1LE camaro/firebird because they are lighter (NO AC and NO power accessories, plus better suspension and brakes). The 1LE's are capable of high 13's bone stock in GOOD condition.

Folks, this is just a little fuel on this fire.

The original post is "Fastest third-gen"--- not quickest. There is a difference.

Does the '89 TTA have a built in speed limiter of somewhere around 130 mph? I am not sure of this.

The L98 cars (at least most of them) will run near 145 to 150 mph.

As far as the 1LE/B4C RSs or Formulas (lighter than the Z's or T/As), weight does not matter nearly as much on a "fast" car as it does on a "quick" car.

If you carry the "fastest" line of thinking a little bit farther, with the better aerodynamics of the T/As or GTAs, perhaps an L98 version of one of these cars would be the "fastest" third-gen.

As far as the Firehawk debate, well, at the time, you could order one and finance it through your Pontiac dealership.

I'm enjoying the debate and just wanted to stir it up a little.

86TpiTransAm

I hear ya man... I hate when people don't recognize that there are TWO thirdgens. The Camaro AND the firedbird. I didn't hear anyone mention the 91/92 GTA which was easily just as fast as the Z28.

Actually "most" of the L98 cars have a limiter of 120mph. However, in my opinion, if you have a good enough engine to get your car up to 120mph during a 1/4 mile run then chances are you also have a good enough engine to require at least an aftermarket chip and most of them have the top speed fuel cutoff (limiter) disabled.

jms

iTrader: (1)

I was under the impression any L98 with the 16" wheels (didn't they all have the 16" wheels?) had no (realistic) top speed limiter (unless you count the TPI unit itself!). Sometimes the overdrive part throttle kick-down can effectively limit the high-speed cruising.

At least my '88 GTA doesn't. 140 plus mph, easily.

I'm still not sure on the TTA speed limiter. Maybe the GNs had the limiter at about 130. Anyone know?
jms

86TpiTransAm

There is no REV limter on the L98's... they'll rev all the way to 1,000 rpm if they could. The STOCK computer chip, however, DOES have a SPEED limiter. It's called the "top speed fuel cutoff". At the set top speed set in the programming (usually 120mph in the L98s), the ECM cuts off all fuel to the engine and prevents it from going any faster. The ECM uses the Vehicle speed sensor to determine how fast the car is going in order to limit the speed. Therefore if A. the speedo is non functional or B. the VSS is non function (which will cause the speedo not to work), then the ECM has no idea how fast you're going and is unable to limit your speed at all. I have actually heard of people hooking up a toggle switch to their VSS and when at the track or during a street race they flip the toggle to disable the VSS so the ECM doesn't know how fast they're going. Of course, they also lose their speedo for that short time but once the race is over a flip of the switch makes it operational again.
