Has this gone down yet? lol

my 323 geared a4 Z28 has a K&N intake, flowmaster muffler, airfoil, and freemods. I raced a 99 trans am, k &n filter, catback, and i walked him hard from anything from a 0-25 roll, and still walked him from a 40. Our longest race went from 15 to 95ish, i pulled extremely hard pulling probably 4 0r 5 cars (no joke) by the time 80 mph came around he was pulling on me hard, and by 95 was only about 1 1/2 cars back. So i believe you could definitly have him the 1/8th . good luck

What's it take to beat a LS1.. a bigger displacement LS1...

jesus guys its only half to 3/4 of a second difference between an lt1 and an ls1 stock, remember we arent driving 3rdgen 305 tbi cars or anything, get a good set of gears, nice set of DR's a little breathability through exhaust and intake and stock ls1's deffinetly shouldnt be a problem. coming from a non biased point of view, i love the ls1 but its very over rated,i have driven them, raced them bought/sold them so i can honestly say i love them not its really not that far out of range. My one buddy in his blue 04 a4 ls1 GTO would get worked by my other buddy in his 93 Zlt1 3.23 a4 car with nothing more than the moroso CAI and an airfoil......think he had an underdrive pully to on the Z. It was never a flukey thing, they ran several times usually from a dig to 100 and the GTO would never get past the back of the door on its closest run

That's cause the LS1 GTO's are dogs..on top of that they are 4200lbs.
The 6.0l LS2 ones however got some guts to them, they can run..

i don't understand everyone saying how the lt1 is so torquey and gets off the line faster than an ls1? the lt1s torque at any given point isn't enough to propel the car 3-4 lengths out on an ls1. and it's first gear...1st gear doesn't take long at all to go through with either vehicle.

i did not meet a comparable lt1 that could get me off the line...or any lt1 for that matter...and i'm in the racing capital of the world.

I beg to differ on that one.. I ran my friends LS6 Z06, both of us with Drag Radials, and I pulled 4 cars on him in first gear. He had to shift, but still I was out ahead. They do catch up though..he was on me real quick..
We were both modded, so it wasn't me vs. a stock car.
Stock for Stock, the LT1 has a little more in the low-end.

lol ya merv 4 cars out of 1st is quite the impossible jump. off the line to 100 stock for stock is most likely a drivers race when referring to 2 equally compareable f bodies. No one said the lt1 is stronger off the line but the LS1 certainly isnt stronger. Ls1 shines over lt1 at 95MPH+, i am not talking about what other people do on the internet, i mean i have witnessed and could witness anytime i feel like calling my buddy out for a few drinks with his 99 SS M6. I mean after my head work or whatever on my DD94 i doubt hed even pull me at 100 usually i can hold a nose length until my speed limiter kicks in. I also just got MT ET streets and a 373 rear end we havent ran since those 2 mods. I think with the new DR's and gears i might dart like a car ahead out of 1st lol but certainly not 4 cars......like 4 cars is almost like a buslength, i just dont see that

I have raced 3 lt1's first one was stock...i had exhaust and intak, needless to say it was not a race i raped him outa the hole on a low pressure street tire and drug his *** all theway down the 1320....second time was my buddy with full exhaust elbow thingy cia pulley and him on mickies....we came outa the whole with me ahead by about a car and i finished by quiet a bit....last time was my same friend but now with slicks, skinnies, a smaller cam lift around .590 duration in the 228s i believe with mods above with new rockers and valvetrain etc....I went 12.504 at the track with lid, full exhaust and he went 13.0 with all mentioned above....my buddie wants to race me with his bolt on lt1 with him spraying 100 shot....i may spot him out a car or two but thats it and i have no fear of losing. lt1's where great a long time ago but times have changed and with a lil traction outa the whole you will not compare on top end.

He might of spun or something.. I know he got right up my *** real quick after. I probably hit second, I wasn't really paying attention to when it shifted. I will say that the LT1 has the off the line grunt..

what is your 330'? that will tell the holeshot story. we can compare cars of almost identical peak whp/wtq numbers, only difference being lt1/ls1 and the addition of ~200 lbs on my vehicle. if i had to guess, i'd say you have yet to crack 5.0 with your 330' time. mine was in the 4.8 area.

hmmmm good point I would have to pull some slips to see where i was at to be quiet honest.....

Traction plays quiet a bit of a roll i beat a procharged vette on the street....no granted there was a huge trail of smoke behind him lol but i still won lol....now if he hooked??? ya i would have had my doors blown off but the driver mod counts for quiet a bit!!! specially in the M6 cars

well ive seen on several websites that the 98Z28 runs 13.9, i believe it was the same sight that had the 93 Z28 running 14.0. So they are more like 1/10-3/4 of a second behind.

erickeown

there are videos comparing the two. I believe its streetfire.net that has a race between a stock ls1 trans am and a stock lt1 trans am. Even though the ls1 jumped him off the line its clear to see that the lt1 passes him. The times at the end were 13.6 for the ls1, and 14.2 for the lt1. It does make sense the lt1 meets maximum torque at 2000 rpms, you only see that in first gear at launch. The lt1 makes about just as much torque as the ls1

i thnk its based more on the driver..i ran my car a few weeks ago and i ran 13.5s all nite..in a 94 lt1 a4 with cai,air foil and exhaust..my friend ran my car the same nite and ran 14.0s

Nikon02

The numbers for that stock 98 must have been with a poor driver becasue i can get my impalla (stock so far) in that range and i have no traction compared to rear wheal drive and all the numbers i have seen are low 13s with some freak high 12s with ls1s. The lt1s i have seen run low 14s stock. I personally have not seen any lt1 go faster then 14 stock. I am sure it has happened but not as often as the ls1s.


I like LT1s and LS1s but after seing dyno charts and seeing drivers that can drive there cars to the stock limit, LT1s do not have that much more tq. The LS1, on all dyno charts i have seen for stock, is still pulling a higher amount of tq from about 2500 on up, and at 2000 it is only like 10 or 15 ftlbs in favor of the LT1, not making that big of a diffrence since the lt1 cars weigh a little more.

As said above it all comes down to the driver mod.

LT1's feel a little torqy but not much. It's mostly because they don't have much top end, so all you feel is down low. Usually the LT1 jumps ahead a little out of the hole because of traction. That's based on gear ratio's a what not. The LS1 can easily spin from a stop. Every race is different, but ls1 will get the win in the end.

I raced a ls6 zo6 aswell, and he had a bumper -maybe half a car on me. He had a catback, while I had everything listed minus the stall & gears. It was from a roll at around 20 to 80mph. Also, my friend beat or tied another ls6 in his ls1 SS with only longtube headers. But this is a different argument.

BTW, aren't we supposed to refrain from ls1-lt1 arguments?

I don't have a current 330' time for this Engine, all I have is my old times. I will let you know in a couple of weeks though. My anorexic car does have a good advantage with how light it is. I will be gaining a little bit in the swap though..

Easy with that stuff...this is just a mere discussion.
