Hey guys today I went to the track with my basically stock 98 z28, I only got 2 runs, my best time was 8.7 at 81mph my 60 ft was 1.8 on those two runs I smoked an 04 Cobra bad, he first ran a flat 9.0 then a 9.4 he had pretty bad tire spin. Also I ran last season 3 times in one day and in those 3 times I ran the same 8.8 at 81mph. So my question to yall is how much horsepower do yall think I have and also how can I increase my mph without much modifications???

Well I run like 8.6 sec. 1/8th mile wise, and I run low 13's, so you've got like a mid 13 sec. car. Sounds like the Cobra owner sucks at driving to me.

yes I know the Cobra owner sucks at driving but I doubt he would beat me really bad, but anyways i got 2.73 gears, would a ls6 intake lower my e.t and higher mph. Also how fast is an 04 Cobra with a good driver at the 1/8 mile. Supposely the guy i raced said that he has gone 8.3

Anybody, maybe somebody can move this thread to kill stories or external engine, maybe there i would get more posts.

if you're concerned about dropping your ET and increasing your MPH, get a stall (research for what speed) and LONGTUBE HEADERS. those mods will kick that car in the *** and then light a fire under it (compared to stock).

just get new gears man, stall and sticky tires. you will be flying after that

I'd keep the stock gearing if you want to keep the gas mileage at where it is. If you start adding gears it's not gonna shave that much time from your 1/4 mile. A stall converter will make a huge difference.

The LS6 intake manifold is useful. You'll add between 5-10whp with it. It's when you start modding that the gains are more significant with it.

Honestly it doesn't seem like your car is doing all that bad getting off the line, with a 1.8 sec. 60'. Sounds to me like you need more power then anything, as your car is charging hard out of the hole. You sure your car doesn't already have a stall converter? Anyways, get some long tube headers, lid, catback and a tune, and you'll be making 335-345whp. You shouldn't have any problem snarfing stock cobras even with good drivers then.

A stock Cobra, with a good driver, could run a 8.4 sec. 1/8th mile IMHO. He'd have to be pretty good at driving though. Sounds to me like that guy is full of it, and most likely just posting what some other person got for times.

well he sure as hell didn't 8.3 then did he! what color was it? can you describe the guy driving it( a friend's buddy was suppose to go to the track that day also) they are suppose to run mid to low 8's in the 1/8 but that is with a good driver! get the stall,long tubes,true dual's and tune and you will whoop his and any others even with mods(as long as it's not a turbo)*** everytime at the track and thats with a BIG GULP in your hand takin' a drink while your racing!

It was a track in Dallas tx, he had a grey 04 Cobra, and also im also impressed with the 60ft myself, maybe because I got new tires on my 18' c5 wheels, so my next modifications would be an ls6 intake with a good ported throttle body, peasseater headers, cam, stall, should that get me into the 7's in the 1/8

If a cobra can drop his 60' to 2.0-2.1 he can still ran mid to high 12s stock. Personally I've seen couple of them runnin low 12s with only filter and catback.

I bought a 04 cobra on a thursday had it a the local 1/8 mile track friday running 8.1's @ 89 w/ 1.9 60ft's all day long. This was a car with just 100 miles on it.

you got a good running one! where are you located?

Brad02Z06

Huntsville, AL.. I have a 02 Z06 now. It has 505rwhp h/c stock bottom end. I have yet to put it on the track. I mounted my slicks and skinny's up on it today and took it for a spin damn does it feel good.

are you one of those vegeance racing dynamo's? TFS215 heads VRX1 cam fast 90/90 etc.....

I have a 2.73 car as well, and it ran 13.2 with a loudmouth. And a 8.55 1/8. Get a stall and you will have a chance with the cobra on the street, otherwise that guy will rape your ***, especially from a roll (unless he really can't drive and misses gears).
It just depends on what type of racing you want to do. If you race 1/8 more often I would change the gear or rearend for that matter to a 3.42, or 3.73 (not too darastic), and go with a good stall too. If you want to do more 1/4 mile, I'd keep the gear, but still go with the stall to help out the 60ft.

Oh, and the cobra wouldn't beat you alittle, it would rape you!!!! There freakin fast on the street, and I don't plan on waisting anymore gas trying too keep up with em'. When I get a stall, I'll be looking for the two that made me look like an idiot back at home..... I can beat them at the track all day long, but when it comes to street racing, their fast!

Brad02Z06

Yep! TFS, vengeance custom cam, 90/90.. Whenever the next nice sunday is I'm heading to the 1/4 mile. I'm looking for 128mph++.

I aint planning on a stall anytime soon till I get a cam and a 12 bolt, in the meanwhile i'm going to try to get and ls6 intake and headers.

with a 2.0 60', thanks to Nitto 555Rs. I ran a 8.520 @ 86 mph when I was bone stock.. That cobra would smoke you stock for stock. Really... , the Cobra can acheive 8.3s or better bone stock, if a pro drove it....

Oh Im a 6 speed 2002 Z28 FYI

Yep, i'm a lousy driver :p

Actually I would probably do better if I didn't listen to everyone telling me my 10 bolt is gonna self destruct at the track. It makes me worried, which takes me off of my game plan. I'll run again on February 10. I'm also not at sea level, so I dunno what my times would be corrected.
