Was wondering if anyone had any track times on these as of yet. Im intrested in buying one as a beater car within the next week or so. What mods are out for them aswell? pullies? nitrous kits?

Good luck with that. There is only 1 person who claims to have one on this site (and that hasn't been verified yet).

So no, no one has 1/4 times yet. but they will be between 14.5 and 14.9.

THE_SLEEPER

Zero to 60 mph: 6.1 sec *other magazines have shown 5.8
Zero to 100 mph: 16.0 sec *other magazines have shown 15.1
Standing 1/4-mile: 14.7 sec @ 97 mph *other magazines have tested this car at 14.2
Top speed (drag limited): 140 mph

* I'd like to see these "other magazines" you speak of, do they have names. 14.2 is quite fast. The best i've seen in a mag is 14.5. other than that was a 14.7 with the ion RL in SCC. all other mags i've seen used GM #'s.

MikeSS

Car and driver did a RL Ion in 6.1 and 14.7, which happens to be GM's numbers. I figure I can get a 14.4 at least beacuse It is cold in Toronto and we have low altitude.

THE SLEEPER might have quoted a Canadian car mag up here, times are usually lower in those mags for reason stated above.

Tooleman

0 to 100 in 16 secs
but 0 to 97 in 14.7.. so it take over a second to go from 97 to 100..

MikeSS

Yup, once you get up around the 100MPH mark, wind resistance becomes quite a bitch. There might have been a gear change there too. But here are some other examples

Ford Fivehundred
0-90MPH = 17.2
0-100MPH = 22.7
Thats over A second every 2 MPH

BMW Z4
1/4 Mile = 14.7 @ 96MPH
0-100MPH = 16.0
Funny thing is that car and driver re-tested this car at the 40 000 mile mark and the times changed as can be seen
1/4 Mile = 14.3 @ 98MPH
0-100MPH = 14.9

So even with the car broken in, it still took .6 seconds to finish the last 2MPH, so over a second for a new car to get from 97-100 is not too bad.

Hmm that is preety impressive. As of right now I am embetween this car, or an SRT-4, so the Supercharged cobalt, isn't even out yet or what? I have really no info as of right now.

newcomer81

it's hitting (a very few) lots this week from what i have found, there is one on ebay for sale. i'm in the same boat as you, but also looking at the wrx as well as the other two. RX8 owners had thier cars on the dyno the day they came out, but i believe mazda did a better job of getting thier cars out to dealers that what chevy is doing with this one. i'm awaiting numbers from actual owners despite the fact that track times really depend on the driver and not the car.

UR2L8

RX8 in my opinion is way too much money. Thats just me though. For 33k msrp (atleast where I am located) You could buy a brand new GTO, or mustang for that much around here. But thats just my opinion. Im basiclly looking for something quick, good on gas, and is fun to drive, I already have one quick car . check sig.

ss xtreme

u can get a rx8 for about 28g not 33 will depends where u live i guess

UR2L8

Everything around where I am is way too damn much money.

osmose

Personally i'd rather have an RX-8 than a 'stang, there are too many around, i like to be different.
GTO may be a diff story, i'd have to test them both first.

ss xtreme

ya i know theres to many stangs i would have a rx8 because there so nice and good looking and u can buy a body kit for that car from the dealer after u buy the car or w ith it. don't get me wrong the stangs are a good looking car but in about a year or two theres going to be alot of stangs on the road for some odd reason then it wont be fun looking at your car that another person have. but one of my friends said that what counts is under the hood that the other person has on that stang then u do u might be pushing over 500hp with something if u know what i mean. then that other guy with the stangs that is stock because u cant tell

I hope to run high 13's this spring after a couple small mods.

MikeSS

I thought you didn't get an SS S/C? Because I hate to burst your bubble, but unless one of these "small" mods is a full out Turbo install, you will be no where near the 13's.

I live somewhere were cars make fast times due to cold weather and low altitude, and here are some of the times cars get.

3400 V6 Grand Am GT with catback exhaust and CAI - 14.98 - fastest non-boost grand am in our club
3400 V6 Grand Am GT Supercharged, throttle body, CAI, exhaust, etc - 14.38
Pontiac Fiero with 3400 V6 engine swap with exhaust and intake - 14.198
3800 V6S/C Grand Prix GTP.....too many mods to list, around 300-325HP - 13.28 to 13.55 depending on day
2.2L Ecotec Oldsmobile Alero (5-Speed) CAI, Cat Back exhaust - 15.21
2.3L QUAD4 H.O. 1993 Pontiac Grand Am (175HP) - 15.10

So unless you are dumping into $1000's into a turbo, and planning to void all warrenties, it will be tough. But good luck to you.

The guy with the grand am that ran the 14.98 is planning a full rebuild of his motor including blue print, cams, lifters, TB, ECU upgrade, etc etc. Basically upgrading every part you can in an enigne. He wants to achieve 13's in a non-boost 3400 grand am, just to see if he can. And after all the work done to his engine, he is still Hoping he can make it.

rm25x

I don't plan on running any boost either. Just lots of juice.
You have to remember how much ligher my car is too compared to the cars you posted.

Weight*/HP difference:

05 Cobalt 2.2 Ecotech (2900 lbs**, 145hp)
97-2003 Grand Prix GTP (3400 lbs, 240hp)
92-98 Grand AM GT 3.4 (3050 lbs, 160 hp)
92-98 Grand AM quad 4 (3000 lbs, 120 hp)
99-03 Alero 2.2 Ecotec (3050 lbs, 140hp)

*Assuming all cars are 2 doors, 4 doors add about 150-200 lbs.

**My car might even be ligher then that because I don't have ABS, or any power options, or side airbags, etc. I have a bone basic coupe.

Also have to take in account:

Auto Trans= 88.0 to 91.5 % Eff
Std Trans = 93.0 to 96.0 % Eff

as dyno proven.

MikeSS

My 2003 Alero weighed in at 2888lbs from the factory. Had no power anything other then locks, no ABS, no Traction control, no sunroof etc.

It was a 2 door and a 5-speed manual. The 5HP difference between my car and your car was all in the intake set up, and since I had a CAI, that voided any difference between them.

I had the fastest ecotec car in our club by far, this includes Grand ams and Cavaliers and the best I could do was 15.21 (on a bloody cold day)

All I am saying is don't be upset when your car barely cracks the 15's stock and 14's modded

And let me adjust what the REAL horsepower of these modded cars was closer to and there correct stock HP and weights

---05 Cobalt 2.2 Ecotech (2900 lbs**, 145hp)
---97-2003 Grand Prix GTP (3400 lbs, 240hp) -> 300HP
---Umm, the 3400 was only available from 99-03. Not available from 92-98 . The 99-03Grand AM GT 3.4 (3050lbs, 160 hp and it is 175HP stock BTW) ->200HP
---92-93 Grand AM quad 4 (2800lbs, 120 hp???? It is 175HP stock BTW? Not 120??? maybe in a base base model, look up what a QUAD4 made) -> 190HP
---99-03 Alero 2.2 Ecotec (3050 lbs, 140hp) -> 170HP? (everyone said my was a factory freak)

Here is even a power to weight ratio for you

05 Cobalt base = 20lbs/HP
97-03 GTP = 14lbs/HP stock, 11.33lbs/HP modified
99-03 Grand Am GT= 17.43lbs/HP stock, 15.25HP modified
92-93 Grand Am H.O. = 16lbs/HP stock, 14.74lbs/HP modified
99-03 Ecotec Alero = 20.63lbs/HP stock, 16.99lbs/HP modified.

So the only car there that made the 13's was a modified GTP with an Automatci tranny which loses some HP through the Transmission. So lets say you need an even 12lbs/HP to reach the 13's. Your cobalt will then need 241.67 unboost HP to achieve that. Good luck added 100HP naturally!

rm25x

No the 100hp is coming from a wet nitrous kit and a couple other small things.

And there is no way a quad 4 made 190 hp, and your alero made 170hp with just a intake.

Can't wait to hit the track and pull some numbers so we can see if any of this works.

MikeSS

OK, nitrious makes sense, that could deff help, but I am thinking after 14.2

And a QUAD4 (not the 2.4L you're thinking of, the original Quad4 of the early 90's) Made 170HP in stock form, and 175HP in H.O. form. The W41 in the Oldsmobile Calias made 180HP and I think there was alimited run around 190HP (correct me someone who knows the quad4's)

And like I said, my alero was a freak. I was running 15.2 while the quad 4's with 175HP were running 15.1's and had the exact same mods (cat back and CAI) were running 15.1's. So it is just a guess.

osmose

you will need to be running a 200 shot to get a 16 sec car into the 13's. And then your engine wil not handle it.

MikeSS

Well the engine might blow across the line (seperated from the car) in 13 seconds!

rm25x

I had a '91 Grand Am with the Quad 4 and it didn't make that kind of power, thats why I am questioning you. Any sites or links that can back that up?

rm25x

Um no. A 100 shot wet would bump the car to 245hp in theory. That would push it to the 13's easily. I plan on pulling some dyno pulls when the car is done to see what its really putting down at the wheels, both on and off the bottle. I have friends who run 9's with camaros and mustangs on the bottle, and they have lots of experiance with nitrous.

MikeSS

There were 3 versions of the 4 cyl in 1991

OHV = 120HP
SOHC 2.3L Quad 4 = 155HP
DOHC 2.3L Quad 4 H.O. = 170-180HP
