this is an update on a post i made a long time ago, this z-28 that was always talked about by my friends as being so fast. he had full exshaust a shift kit, cold air induction. then for christmass he got headers and a pully , this is all on a 96 z-28 auto. ther was alot of shit talked at first but then things cooled down and i shut my mouth when he got the stuff for christmas. our best friend is always saying quit bitching and race . but for the longest time i had no mbc adjustment screw!! so finally i got that damn thing, and tonight he came up to my work with one of our bigger friends. there was no talk of raceing but as we were leaving at close, we came to a double left turn with a red light. so i gave up the launch, we came around the turn , he was on the inside, and i staye din first incase he wanted to go. we got on the straight away and he punched it, i saw his lights raise, and just as we get even i go wot. i instantly gain 1/4 car then i shift to 2nd and gain another 1/4 length to put his bumber at about my rear tire. BAM, i hit feul cut , and shift to 3rd, he gained just a little from my shift and he stays right behind my door till i hit feul cut again and shut it down! i figure that from a roll with out the other guy in his car we would be pretty even , maybe even him edging me out. but from a stop, ha, it would be all over, now the shit talking has finnally come to a close and questions have been answered. too bad im getting a couple more mods with in the next month, o yeah. oh by the way my mods are

92 tsi 5 speed, 92 octane gas
act 2600
pvc custom intake pipe
k&n intake
full 3" exshaust, straight through, no cat
mbc set to 15, but i get really bad boost creep
mildly ported head, 3 angle valve job
ported 2nd gen exshaust manifold
ported o2 housing
boost gauge

i think thats all
yeah i know i need a feul pump , i actually have anothe post going right now on what mods i should do, check it out and give me your opinion.

p.s.
i just heard that the guy with the camaro told the big(fat) guy that if he ever raced again with him in the car he is gonna kick his fat ass out first! ha, he had no idea the power of dsm!

sorry for any runons, its late and my body achs from adrenaline and working out!

good kill

Good job man, sounds like you really need that fuel pump. I think it probably would of been pretty even if the "fat guy" wasn't in the car. But from a roll i'm sure you would waste him :D
NE way keep up the good work.
:D

hmm

Why do you think you are hitting fuel cut?
I dont hit fuel cut until I I boost to 20 psi and then still only in cold weather.
Have you hogged out your MAS?
If not that should be your next step.

LT1's have to have a lot of work done to them before they really wake up. My buddy from high school has a 96 Z28 6sp and stock it ran 14.5. Intake and Exhaust took it to 14.1, after a vortech supercharger and all supporting mods he was running 13.0's. I'm not impressed. On the other hand my other friend has a 2000 SS Auto...stock it ran 13.2, borla exhaust and K&N took it to 12.7's...NOW I'm impressed. Those LS1 engined cars respond to mods almost like a turbocharged car does.

What are you talking about? These are 280 hp 3500lb cars. How fast do you think they have to be? That is within resonable quartermile time for lt1's.
My 94 TA with absolutely no mods ran 14.0. and that one had 275 hp. Trap speeds tell more about a car than ET. Best trap speed on the 94 was 99.7 with just a K&N Filter. Best on my WS6 before new motor was 104. My WS6 just had K&N Filter, Borla, and pullies. LT-1s aren't dogs now ;)

As BAD 97 said, a more reasonable time is closer to 14 flat. 14.5 is definately on the lower end of the spectrum, which usually means a lack of driver skill. It's like a bone stock GSX running a 15.7

I ran 14.1 Stock...first run ever at the track. First time ever at a track. 2months after I got the car with 74,000 miles on it!. ;) Driver Skill? Naaah (Modest ;) ) Car? Hell yeah

Those of you with LT1 powered cars posting 14.1 sec times for your cars bone stock remember one thing...you (at least the last poster) have an auto tranny...which makes staging and launching easier. There is less shock to the tires and makes getting off the line less of a tire spinning affair than does a 6sp...my buddy had a 6sp and was running on radials.

i remember seeing a REALLY chitty time for the first f-body with the lt1 motor. Something like 14.5 was the best for the first year of the lt1.
Was that 94?
93 Was the first year for the LT1 in a F-Body. 93-95 had single cat exhausts, and 96-97 had dual cats (some 95's had dual cats). 98 Was the LS1's curtain call...and when I cheesed in my pants over a V8 all over again since I had my 69 Camaro.

hey guys,

i already have my lower honycomb out, i am thinking of taking out my mass today and open up the lower half alittle more. i think the reason i keep getting feul cut is cause i have been getting boost creep really bad. bu that will all be solved within 2-3 weeks, im getting a bigger turbo,feul pump, ic sprayer, pocketlogger, and port the hell out of my 02 housing. by the way about that guys z-28, he races all the time and so far he is one of the fastest 1t-1 around hear, not saying he is super fast, im just saying that there arent many fast 1t-1 around here. he is gonna put gears in real soon , but im not to worried:D also all of my friends are in shock that i beat him, my one friend was trying to make all excuses for why i won.

An auto with full exhaust, and intake will pull low 13's all day. try looking at camaroz28.com.

Your buddie is the worst driver I have ever heard of....

I mean holy shit, in an auto, green light...step on gas run 13.
Its hard to screw that up.


I ran 12.9's @ 108 w/ 2.0 60' time on cheap radials with full exhaust, intake, chip, and pullies. This was in a 93 Z A4.


You must have one fast ass stock turboed 1G to beat a car like that from a roll......

Man, you haven't been out in the real world for a while. When I pulled 14.2 in tsi all day I used to mess lt1's real bad all day long. Ls1's are the only chalenge for me because they are the ONLY real fast STOCK F bodies. That is just a point of refferece I mean if I pull low 14's and you cant beat me u must be slower.I have videos of lt1's barelly pulling low 14's and I am talking about at least 10 cars in one day at the track. According to you MOST camaros have bad drivers( if they don't pull 14 or lower). That seems to be the #1 excuse for anybody when a camaro gets smoked.

I can't believe an LT1 Z-28 can only run a 14.5 with a driver that can drive the car even a little. Everyone knows how much faster the LT1's were/are compared to the L-98's. I bought one of the first 5.7l IROCS when they first came out. I took it to the track without even breaking the motor in and ran 14.357, 14.357, and 14.339 on the three passes I made that day all at a little over 96 mph. There's no way that car had a chance against an LT1 car but according to the times posted I was faster. I've just seen too many stock LT1's running 14.0's on radials and mid 13's with good tires and a good driver. Even faster still with mods.
 
#20 · (Edited)
Let me get in here and clean house stock times here.
LT1 around 14.1-14.4
LS1 Ive seen everything from 13.9-13.2
and as for those old ass IROC hillbilly mobiles 14.5 and up.

yank thats lower honeycomb and no more fuel cut. when i had the same mods as you i was a fuel cuttin fool. i pulled that lower honeycomb and bye bye fuel cut
:D
I pulled mine and now I got knock. Maybe its because my turbo isn't spinning? hopefully anyways. No problem with fuel cut. Only time I got that was when my car was badly (actually not ven) tuned.

Nice win over the LT1. Those things clocked quicker in Motor Trend with auto tranny's than the manuals. But since you guys raced from a roll, it probably hurt performance. Like they said taking the lower honeycomb out helps delay fuel cut but I'm debating taking a side one out b/c if its in the 20s I can still get FC at 18 or 19 psi.

Be careful when pulling out that honeycomb. Better have an Air/Fuel gauge and EGT. That is air that the computer isn't seeing. Therefore it isn't richining the mixture. That can lead to some bad stuff. My 2 cents.

OK guys, here is one of my many "Kill Stories". I was cruising down Avenue F in Del Rio in my 1989 Chevrolet S-10. This guy pulled up to me in a Z-28 with the LT-1. He wanted to go, so when the light turned green I floored it and beat him by about 2 and a half car lengths by the next light... OK now, if this story sounds REALLY retarded to you, then you know what I feels like when I read some of your posts. The really really sad part is, that I did used to race Eclipses and Talons all the time. I can safetly say that I was never beaten by one of those turbo charged dual overhead cam FOUR cylinders. All I have is a stock 4.3L V-6, and I never lost to an Eclipse. The worst thing about Talons are the people who drive them. For some reason, as soon as people buy a Talon, they think they have a race car. Another thing, it is spelled FUEL, not FEUL! And finally, 92 Octane gas is NOT a MOD. Hahahaha. If it were, I could go to the local Texaco and fill my tank with some high performance mod! I am tired. I will think of more stuff later. Bye friends!!

Oh yeah, and here are the MODS on my truck:

92 Octane Gasoline
Fully inflated tires
A fresh oil change
I lightened my truck by washing it yesterday and removing my stereo antenna.

That is all I can think of right now, I will add more as they come to me.

"The worst thing about Talons are the people that drive them." Man, I'm glad I drive an Eclipse and am not included in that broad, misinformed insult. (6'2" 330 lbs by the way) And I must say that you were indeed fortunate to never get beat by one of these awful people in an Eclipse or Talon because most of them will make a stock 4.3 liter S10 look silly. Keep racing them. You'll find out what I'm talking about soon enough.

first of all i was typing fast and my whole post was filled with miss spellings and all lower case letters. plus im pretty sure i said please exsuse that due to the fact that my adrenaline was rushing and my whole body was sore from working out.
secondly i posted that i was useing 92 octane, not because i thought it was a mod , but inorder to let pople know i WASNT useing race gas.i guess if we all followed your logic i also listed my car as a mod, and what do ya know my transmission is a mod too.
just because you raced some stock 1.8 liter dsms and maybe a few stock turbo dsms doesnt mean anything, besides your car is slow if you are even worried about raceing them in the first place. why would someone such as yourself post on this board if you have so much against our cars and 4cylinders in general?
you obviously have something up your @$$, maybe your mom hid the keys to your super cool and really fast truck? i wish you lived near me, i would show you how fast your truck is, maybe we could race for titles , but then again i dont want that slow hunk of metal you call a car in my driveway.

and again sorry for not taking typing class in highschool!
