What's up with your V6's, why so slow??

No flames!!

Now i used to have a Pontiac Firebird V6 (dearly departed ( ). When i bought it two years ago, it was in MINT condition, so i never even bothered doing anything to it. Hardly ever even popped the hood. I assumed it was bone stock, just by looking at the exhaust and the engine.

The car was quick! My kill list included a brand spankin' new 5-speed Celica GT and Ford Lightning (by a bumper), plus a late 80's Mustang GT.

As hard as it is to believe about the lightning, i dunno. I couldn't see the guy cuz he had tinted windows and it was nighttime. But he was definately going for it, we both took off hard at the light and just floored it from the roll (at least i floored it). It was a short race up to about 45 mph. On a cold night, with only a pint of gas in the tank, amazing things can happen.

But my car could hit 30 in the low 2's. I see all your times all in the low-mid 3's at best, with all sorts of mods. But after 40 the car was a dog. It still hit 60 in under 9. I'm sure i coulda hit HIGH-7s if i emptied the gas and took it out on a cold night.

Now don't get me wrong, I'm not trying to dog on your cars. But was my car by any chance possessed??? What kind of mods could the car have that i couldn't see? Thermo? Chip? Cam? Ignition? Hiked Fuel Pressure? Another thing i noticed, my car had the cleanest start i've ever seen. Better than many of the luxury cars i've driven at work. Even a quick flick of the wrist was too long. Definately didn't have gears.

Then i figured i was hallucinating, so soon after i got a chance to drive someone else's V6 with all sorts of exhaust mods. The car was excruciatingly slow. I dunno, it's really confusing.

BTW, if it helps. My gas milage sucked. As low as 8 mpg (very rare) i averaged about 13 mpg. But on long road trips averaging 85 mph, i could get about 27.

Well, considering you said it died after like 40, you coulda had a lower gear in the rear. That would increase your 0-60 times. What year was yours. Cam work, MPFI porting, Chip, aftermarket exhaust, anything could have increased your times.

Next time, try naming your post a lil different. I'm going to keep this open, but if it starts to turn into ANY type of flame war, it's locked.

Yeah, i thought about that after i posted. Shoulda been "What's up with my V6, why so fast?"

Mine was a '91

Car: 85' Firebird (Project), 92' RS
Engine: 2.8L, LS1
Transmission: 700R4, 4L60E
Axle/Gears: 3.42 Open , 10 Bolt (ukn)
actually, i think that 91's had slower gears, 3.23 vs. our older 3.42's. My car is pretty quick, well, peppy for a v6, it'll get up and go when i want it to, unfortunately now it only has 2 gears but anyway. NOw with my old 2.8L i was able to hang with 305's running on 7 cyls or 8 weak cyls (please no flames) made a decent run against a 350 El Camino once, from a standstill-he beat me by a door it was nice, well actually the guy only said it was a 350 but judging by the 10in. tires on the rear, the candle apple paint, and the "phat79" lisence plate, not to mention a really nice sounding exaust note with dual pipes, i'm assuming it was either a 350 or a beefed up 305. I'll go ahead and post my kill list, but just last week, i raced a v6 RS, he held with me at first, but when my car hit 3100 RPM's I left him in dust, ended up pulling nearly 3 car lenghts on him by the middle of second gear (55mph) then i stopped it. Anyway, some cars come off the assembly line faster, some cars are well-kept, some cars are dogged by the original owner, My father was the original owner of my car, so i know all the stories of what it's gone through, and the upkeep he did. Anway, i'll end this now. bye.

A SVT Ford F-150 Lightning??? That is REAL hard to swollow! Don't get me wrong, I love my '89 Camaro V6 to death, but I've had the pleasure of driving one of these trucks and it could kick the **** out of my car. I'm not sure on any stats, but it is one fast *** truck. 0-60 in a blink of an eye! I normally hate Fords, but after driving this, I was extremely impressed.

yep, zero to sixty in less than six. Maybe he was a crappy driver. I know the guy in the celica gt missed a shift, but it didn't matter cause i heard from about three cars ahead of him anywayz.

Yeah, I tried a Ford Lightning a few years ago when my 'bird was in prime shape. I kept up til he realized I was trying...

Personally, I've stopped messing with chassis that are larger then mine, cause after the SOB stomped me like two lights in a row and I was just having fun and passing time on the way to my grandma's by even trying, he literally tried to run me off the road. Sore winner...

As for low end, yeah, sounds like you had some killer gears out back, low gas mileage, ***** up to 40, was it a real high revver on the highway at 60 or 70 do you remember?

Ok, I just checked. With me (200lbs) a 50lb floor jack, and other crap in my car, on a full tank of gas, with the AC on, and spinnin my tires, I ran 0-30 in 3.12, and 0-60 in 9.21. Also keep in mind my car has 156000 miles on it, so I assume that's ok.

No it wasn't a high revver on the freeway. 2000 rpms was about cruising speed. That's why i'm pretty sure there were no gears, but i did notice that i could crack 6k rpms easily on launch, it only took a split second to get all the way up there.

I have a friend who owns a little 2.8 crossfire injection camaro. Its a scraming little suker. "and its pink" he took me for a ride when he got it, the little 2.8 went 115 in a little over a qmile. he actualy beat my 82firebird 305 before i made some $$$$ mods. but he did kill a few ponies. i think they would die if they knew they got dusted by a 2.8.

Actually, my parents had an 89 Celebrity (2.8), i use to drive when I was 16, and I know what your talking about, it was the strangest when you started it up, you could let off the key after cranking it for 2 seconds, and 2-3 seconds later it would suddenly be running.

I had two friends, one was driving a 79 Ford LTD (302) and the other had an 87 Pontiac Pressiane(305) (spelling?)

We raced to about 60-70Km/h, and ever time I would toast them, I had to race the pontiac 3 times, the first two times he had excuses, and the third time he gave in and said I won fair. Mind you those two cars could do a very nice one wheel burn out, while the Celebrity was a small chirp...

Sigh...SUPER, what's the matter with you? There's gotta be some foolery happening with that car. The crossfire injection system was only available in 1982 and 83 models. And only the 305, to boot. What did the air intake system look like on the car? Also, the crossfire injection system is nothing more than an ordinary TBI system in which the injectors feed the opposite engine side as to which they are on. The stock 82 CFI 305 only cranked out 165 horseys at 4200 RPM. While it did push a respectable 240 lb-ft or torque, it would not have been able to hit 115 in the quarter, given those stats. Next time you see your friends car, count how many spark plugs he has on that thing. I'd love to see how someone could have bolted a V8 CFI manifold onto a V6.

Agreed. There is no way that the 2.8 your friend had was crossfire injection. The 82-84 2.8's were ALL Rochester E2SE 2bbl carberuators. The 85-92 2.8/3.1 motors were ALL multiport injection.

Your friend had a sticker.

hmmmm If I had a z28 and has rs badges on it I'd say "this is my Z28. I put newer ground effects on it from a '91 rs, so it would look cooler." or something to that effect. otherwise I'd just pop of the rs badges and put the z/28 badges where they belong.

i just thought of something. i can say my '88 v6 is a z/28 then. "yup this is my '83z z/28-'87 IROC-'86 IROC-'92 z/28 - 88 sport coupe. my '83 z/28 hood, '86 iroc gauges and tailights, '87 IROC foglights and drivers side fender, and '92 bowtie grille must make my v6 so fast that it's faster than all those aforementioned cars since it's got a bit of all of em' on it.

Shoot, if I had a V8, I'd put V6 badgings all over it and race like that cuz when other people with 8's in there cars think they're about to blow a 6 off the line they'd get on heck of a suprise instore for them.

When I junked my V-6 I left the badges on. Too bad it's obvious that I have a V-8. That damn thing sticks out of the hood 3-1/2 inches. I know what you guys are saying about the 6's being so slow. Mine was hurt when I bought the car and I kept thinking the moped riders were laughing at me.
