Hey Guys.. Sorry bout so many questions.... But... My good friend has a 1995 Camaro Z28 Auto. It has DynaTech LT Headers, 3"exhaust, No cats, Hooker Aerochamber Muffler, TB bypass, CAI, 3.73's. He thinks this thing is God... I love the car.... have nothing bad to say about it, and its fast as hell. How bad is this thing gonna beat me? Traffic light race? 1/4mile? I KNOW hes gonna smoke me at speed, but will i be able to keep up with him from a stop. (Pretend im a good driver) I just want to keep up for a little while.... Any imput is great . The Vette is a stock 91 L98 6-spd, with 3.45s

I've beaten a LT1 Z28 like that one at the quarter mile more than once. On the highway you can hold them off to about 135mph or so, then they will sloooooowly pull by you.

Lose your mufflers (replace them with Ansa Resonator Tips), cut a hole in your airbox, remove the MAF screens and see how it wakes up your car. It might be down to driver technique at that point. (And you can do all of that for less than $100.

THEN drop in a 100 horse shot of squeeze. :lol:

Anyone esle?

I've been to the track a couple times with my buddy who has a '94 Z28 (auto). He has a borla cat-back, k&n filtercharger, and some sort of an aftermarket throttle body. Every time we've raced it has been extremely close, but I routinely beat him by .10 to .20 I usually get him pretty good out of the hole and he can't quite make it up in the 1/4. His best at the track is 14.0x and mine is 13.89 although he usually has a higher trap speed by 2 to 3mph (my 98-99mph vs. his 101-102 mph). With your buddies mods he'll prob. get you, but it should be a good race.

I don't think you should have a problem. As long as you get a good take off, you should be able to beat him. My girlfriend has a 95 Z28 auto, and I raced her couple of times. No contest. Her car doesn't have much, except for cold air intake and flowmaster exhaust. Even though, she thinks she won one time. When we took off, I was even with her for a little while, but I was going sideways with my tires spinning. I still can't convince her that I didn't have any traction :boxing but, oh well. After 2 months she's still giving me a hard time about that :smash:

His gears will help him alot, especially outa the hole and from a slow roll. His exhaust sounds like a good setup and would probally net him a solid 25hp cai is worth 0.10 also. It'll be close. Dont be surprised if you lose but it shouldnt be by much.

StealDads67

There is a big difference between an LT4 with mods and an L98 stock.... And wat are Asna tips or whatever you are talking about?

65Z01

Since you have a 6-speed with 3.45s you might run high 13s bone stock.

But why race his mods with your stock Vette?? Lose the "frisbee", install a 160 deg stat, a K&N and cut air filter lid, unplug your A/C pressure line sw to keep the fans on, lose the spare and jack and go to the gun fight with 1/4-1/3 tank of gas. You should gain 20-30 hp and even the playing field.

Then you'll have to learn to launch, learn the best shift points and to power shift; if not his A4 will eat you.

You've got mail with some ideas on mods.

My friend had a 95 auto with similar mods (same but w/o the gears and but had a cold air intake). His car ran 13.5@103. It looks like he might beat you. I would practice my launches off the line (no tire spinnning), you might be able to keep up with him to 0-60.

They're a set of exhaust tips with a baffle in them. They're a very inexpensive way to lose the weight/inefficiencies of the mufflers and still retain SOME control over resonance. Be forwarned, going cheap on your exhaust may give you some interior resonance at some RPM ranges....I didn't have to worry about it too much as I've got a convertible. Have a muffler shop make a reversible modification (remove the stock muffler, use clamps to attache the pipe/ANSA tips, then you'll be out a minimum if you find you can't live with it.)
It DOES make the vette sound like it oughta. :smash:

vader86

you can beat him, youll just have to launch correctly

blk90rdstr

A 1/4 mile race will be closer than you think. If you add the same money to your car that he did. You win. :cheers:

StealDads67

Do you guys really think its gonna be close... even with all the mods he has? I think he would cry if i won.... It would be great. ( I dont see it happening)

blk90rdstr

YES. His 3.73 is gonna lower his MPH in the 1/4. My friends LS1 T/A was faster with 3.42's than with 3.73's although the burnouts were nice with 3.73 but thats why people THINK its fast. Have you done the cheap/easy mods they may be the tenth you need to be a winner. If your car is healthy in good tune with basic mods and you drive perfect I predict Corvette 13.70 Z28 13.85 in good weather. :p:

The gears alone should be enough to make him walk you from a dead stop. It's really best not to race an auto from a dead stop, but rather from about 30-45 mph. Auto's have really large "dead zones" where they can't accelerate worth a damn. Most of them with that type gears have that dead spot right at 30 mph. Get him from there and you'll walk him. Get him from a dead stop and you'll be seeing tail lights. It's very hard to beat an auto out of the hole.

As an example of the auto "dead spot" I raced a friend of mine with a 98 Z-28 with a high stall converter and 3.73 gears, along with heads and cam, etc. This car dyno's 406 horsepower to my 336 and he run's 11.70's to my 12.80's. From 30 mph he could not pull on me an inch and we ran it all the way up to 100 mph, where he probably would have started to pull me again. He gets his huge advantage out of the hole. If he puts 2 car lengths on me at the light, sure he can't pull me anymore, but he's already ahead so it's all over for me. If you're already moving and you get up beside him, chances are he is not gonna have the right gear he needs while you have 6 choices :)

Honestly I don't think you can beat him. No flames intended at all, but look at the math. You will do very well to get high 13's out of your car if you can drive it right. That Z-28 should run high 13's completely stock, gears do wonders for auto's at the drag strip, they are consistent as hell. To be honest he's in low 13 high 12 territory if he can get a good launch. Now if he can't drive you might have a prayer, but it's a whole lot harder for him to screw up. If he gets a good launch all he has to do is keep it pointed straight, you've got a few more things to worry about even if you do have a good launch.

hey guys-
the mystery person is me :seeya
you guys may have gotten the wrong impression
me and kev aren't sworn enemies- :mad
were actually damn good friends :cheers:- his dad does all the work in my car i can't do myself :conehead

as far as the ls1 with 3.73- someone can't launch:rolleyes:
either that or its because the LS1 is all top end and the way his gears/shift points lined up in the 1/4 weren't optimal (he had to shift with 1 sec left)

mine however will work nicely- :D
i'll be about 500rpms off my redline when i cross the line @about ehh 106

I am a frequent poster at camaroZ28.com
:jester
from what I see, i should be able to run very low 13's or high 12's with this setup. :eek:
Right now he'd prob beat me though b/c i need to get the PCM fixed- i'm bouncing off the rev limiter with the gears- which is normal from what i've read
while i'm at it 180 thermo and leaning it out at WOT too- (PCMs for less GP- if u guys want in let me know via email)

I forgot this- i don't know if kev mentioned this but i'm also racing on mickey tompson sportmans :)
low gas (I NEVER HAVE GAS! I HAVE NO MONEY :() and wieght reduction
(!rear seats, 5th speaker, !front sway bar, no winshield washer fluid, floor mats, !airpump, - bah this list goes on-and all the usual crap... it all adds up though man

Now if only you didn't lose my freaking cut out kev!!!!! :mad:

But in all honesty-
We help each other out- boucing ideas around:cheers:<--and that- were not competitve against each other as much as we are against the clock :boxing

later guys

LPDesRoche

Its very possible that you can win, some of the L98's are very strong. Just remove the "Frisbee", bump up the timing, K&N filter, cut the air lid open, and a good tune up. You shoud fair pretty well. The trick is to launch the car good, and don't over rev it when shifting. Shift at 4800-5000 no higher. I could get consistent 13.70's out of the 90 before the mods got serious.

TreyZ28

yeah but don't forget- he paid $9750 for his car
I paid $5700 :p:
so i got a $4k head start
I love his car and I havn't even seen it yet- its perfect for him
This kid's camaro pulled- what .83 g's? and everytime that wheel turned u bet your butt you were grabbing ahold of that "ohh poopie handle" and feeling .83g's. vette should suit him perfectly
he's also all about low end and making every last horse run its behind off!

good luck with vette kev
can't wait to show u my 12 sec slip when i see it next monday !:cheers:

With my 1988 Corvette I beat a Z28 White with Orange Racing Stripes (I think this was 97??).

I think he had an auto.

Anyways My car just pulled away slowly at a 50mph punch.
My vette was an auto.

But he is modified so I think he would probably pull on you.

I was always told that the newest version Fbody is always one step behind the newest vette. I.E- L98 Camaro = L83 Vette, LT1 Camaro = L98 Vette. I dont know if this is true, but that is what I have always been told.
