my car in sig and his car is bone but a flow master. who would win? oh yea for the time being till i have the money my car is one wheel peel or before track opens back.

 

im liking the ls1 for this one

 

Drivers race in anything less then the 1/4 anything after that he'll likely pull on you.

 

what about if i put a posi back in it?

 

If you don't have a posi, you're wasting your time. With one, I say it's too close to call..

 

at my home track, an bone stock auto ls1 trans am on drag radials runs 12.70 dial in..

 

1998's were slower, and drag radials can make a big difference...

 

is the trans am a WS6? auto or stick? what gears are you running with the open diff?

your not too far from me so avg height above sea level is about the same. a couple of my friends have LS1 T/A's (98 and 02) and they run low 13's with full exhaust and CAI. id say that if its not a WS6 and you can hook up well, you will win from a stop but from a roll the LS1 will get you.

 

1/4 mile race he might edge you out but I think you have this race.

 

LS1 wins

 

not ws6 and auto. open i have the 4.10. but the fastest ls1 motor car at the track i have seen is 13.4 and that was an 2002 ss with no bolt ons but exhaust.

 

Unless it's a factory freak you'll have this one. Contrary to popular believe not every LS1 runs 12's from the factory

 

well if you can consistently cut that 12.9x in your sig, i would put my money on you. the non WS6 LS1 T/A's have 2.73 gears which is what i think will give you the edge...

fwiw, my friend with the 98 T/A is a non WS6 auto car. first time at the track he ran a 14.4. after 3.42 gears, CAI, and pacesetter LT's to an X-pipe, he cut it down to a 13.2. my other friend with an 02 WS6 T/A with CAI, pacesetter LT's to an SLP Loudmouth catback, and 3.23 gears runs consistent 13.1's. i think he may have pulled a 13 flat or a 12.9 on a really good day with cold weather.

 

Either you're at a high elevation, your track sucks or your friends can't drive worth a damn.

 

With your E.T., it would honestly be a drivers race. a 12.9 is about the limit to a Stock MANUAL LS1 in my opinion.(everyone here is going to tell you a different time that LS1's can run stock, and im NOT saying everyone else is wrong either) But if i had to lay down my bet, Id give the W to the LS1 because IMHO, Its got newer efficent technology and a better geared Tranny.
However if you ran your posted 12.9 quarter time with an Open Diff, You would take the Win with your Posi installed, cause i know your prolly gettin wheel spin bad with them 4.10 gears. But hey who knows??? alot of it is how you drive your car and if u can get that launch.

 

true but most of the friday cars still trap at least what hes trapping. If he comes on a tire, its gonna be a drivers race.

 

low elevation, "House of Hook" not a crappy track, and friend with 98 T/A cant drive and friend with 02 is not bad but not the best.

 

hey ls cars with a standard driver is a 13 sec car contrary to popular beleif..... notice he said dead stock with a slowmaster muffler....

if you ran your best of a 12.9 with an open it will be dead even should be drivers race for sure.

i'd get me a posi and d/r should pull you a low 12 then i'd bet lol.

 

All i can say is get it on film, it will be a close one.

 

i had a posi but broke it the last test and tune of last yr. kinda made me sick so i aint put any money in it. but i will before the track opens back.

 

I would give you the win. The 98 LS1 is a strong car but like someone else said on here they got stronger with the revised cam, intake, and actually differences in the block. The LS1s are great cars and with normal drivers they are pulling higher 13s but a good driver will get it in the mid-low 13s no problem, and with drag radials they have been known to dip 12s without any issues at all.

It will be close but I am taking you for the win. LSX cars come in to their own when you get closer to triple digits. That is when they take off.

Good luck and get it on film. Should be one hell of a race!

 

what mods are on the ls1? my friend has 00 TA auto with a lid and a cutout and drag radials and he cut a 13.2 @103mph. this was 68 feet above sea level. and my car while it was stock besides slp lid and k&n filter ran a 13.32 @ 108mph with a 2.24 60' and this was my first car with a manual. From the looks from ur sig, u will edge him out in the 1/4 mile but the ls will eventually pull u on top. make sure to video tape the race

 

this ls1 has nothing done but a flowmaster and its AUTO NON WS6! the guy just got it three weeks ago. i have rode in it dont seen vary fast. and it spin really bad. i dont think ill have a problem beting him.

 

here at ATLANTA DRAGWAY IS A CRAPPY TRACK ON FRIDAY NIGHT

 

STOP TALKING, START RACING!!!!!!!!

 

I know I know the one thats in front when you get to the finish line...naaa I would say you should prob win but thats why we race

 

SS/z28/ws6/ really doesnt make that much difference power wise. If he runs you on street tires i hand you the win. However basing off what an average auto ls1 traps, you put a tire on it and it will be a close race and i would expect the ls1 to pull you up top

 

Lot of misinformation about LS1s in this thread. Nevertheless, if you are pulling the times in your sig, I think you may have this one.

 

like what if i may ask?

 

With your trap speed in your signature, it should be about even going across the traps, but it looks like you can 60' better than most bonestock street tire 98's. You should have him as long as you get that posi fixed. Of course if it has 2.73's, your at an advantage already. Good luck! Tell him he needs a pair of Drag Radials and a 3600 stall to dip into the 12s!

 

i agree to an extent. they trap the same and obviously his car hooks pretty well so he SHOULD have the advantage. However, i dont agree the ls1 car would need a huge converter to "dip" into the 12s. We took a stock ls1 car and with a good hook and a converter of that size and it went 12.25s all day @109 on a 1.6 60'. Bfg drag radials at that.

I have also seen a exhaust only 00 b4c with 160k miles on a good hook go 12.80@111 with the stock converter. same bfg drag radials.

NOW i do agree that the margin of ls1 cars that run 12s out of the box is slim, but they are out there. My exhaust only SS on a 2.2 60' went 13.18@109 and on a tire that couldve easily been 12.70s or so. But around here the slow ls1 friday cars still trap around 104-105 area in an auto and a couple mph faster with a t56.

obviously the leave is where this race will be won, or lost.

 

well... on average you don't see a bonestock '98 ls1 with only a a converter and a tire doing 12.25. That is a bit on the quick side. I'm only referring to average times. I know how fast they can be, but not everyone can do that with them.

 

agreed, but just lowering the 60 foot times on these cars and its a good possibility that you can "dip" into the 12s with no converter at all

 

Low enough 60' with an LS1 car will blow out the stock rear, many owners don't launch them to full potential for that reason

 

only if you get some traction. we have people at the local track launching from 4k all day long, all they do is light up the tires and run mid 13's to 14's.

 

did the race even happen?

 

Fair enough, but mid 13s - 14s are not impressive for near stock LS1. They run better times with a softer launch with traction rather than with launch wth bad wheelspin

If I race any LS1 f-bodys I hope its from a dig

 

dead even at the 1/4 mi mark. but he pull on me hard after that. my car is in need of a tune up been driving it to work. oh and he add slp lid to his car.

 

changed the plugs car was still running bad. number 8 plug was fouled. so check spark frist thing and find my problem number 8 spark plug wire stop firing. i changed it and it fixed it.
