People please post you quarter mile times for STOCK LS1...Auto and manual...third gen camaro and trans am...thanks

 

You'd better start by defining that. From what I've seen lounging around here, there aren't many (if any) 3rd gen LS1 swaps that stay completely stock.

Mine is stock internally, but has long tube headers and LS6 intake. Would that still meet your definition of "stock"?

 

Also depends on how much was removed from the swap car when the new engine went in. Alot of weight can come out

Gears play a big factor. Mild to wild swaps on here have had 2.73(mine) to 4.10s. HUGE difference irrespective to the engine

Next, what parts are allowed on this stock swap? LS6 intake? What type of Y-pipe? Cats? Intake tract?

Lots left on the table that noone follows the same path with

 

Good points. I also deleted EGR (comes naturally with the LS6 intake) and A.I.R., have 4.10 gears, and have dual exhaust in the works.

 

For reference my 2.73 geared auto 99 trans am full weight non ws6 went 13.4 at 104 in summer heat. Thats stock everything but has MTI lid and had some crappy glasspack that was less than 2" id diameter!! Thirdgen being much lighter would go bottom 13's.

6spd with better gears is high 12's all day. If you get different exhaust and a tune, thats mid high 12's easily. auto cars can be high 12's witih exhaust tune as well but may need more gear like 3.73's.

Lots of variables here.

 

I have a small cam in mine, ported heads, stock LS1 intake, stock manifolds, but will be running a 2.5" Ypipe to 3" single catback. 4" CAI, stock tranny and stall, 2.73's in the stock 10 bolt. I did get rid of all the spare tire junk, all the emissions equipment and all the A/C equipment. Honestly I am hoping for mid to low 13's, which I am sure I can attain as long as I can get this motor to actually run (month 14 of the swap so far lmao). I have no idea what it will actually run, I am just hoping at least a 13.5 or below, I'd rather be pessimistic and be happily surprised later. I am going to need new tires though because my current ones have a good amount of tread left but they seem like they are made of hard plastic, no traction at all. I almost thought my 305 was powerful because I could leave 2 big long patches with it even.

 

yes guys im mean stock engines...not bored,stroked or cammed...stock 5.7L LS1..cold air intake and exhaust is a must for all of our third gens..so those two i could care less about...if running a auto, just post times using the stock torque convertor..stock injectors, cam, heads (no porting)....LS1 or LS6 intake (intakes dont matter to me)...egr and a/c doesnt matter either...just post what you got and post the results..thanks

 

I would guess that a stock 01-02 LS1/T56 3.42 geared 3rd gen would easily be in the 12's at 110mph.
I drove my buddys bone stock 02 WS6 6 speed car at the track a few years ago and was able to get a 13.2 @ 109mph after driving the car only 4 times, which were the 4 passes I ran at the track. His car was about 225lbs heavier than my Formula.

 

I have wondered also, but didnt want to ask.


Is there a registry of LS swapped cars, and times?

 

No registry, you're lucky to know whos got a swap by browsing the post pictures threads. You can imagine theres tons that dont post

 

12.8 last year with a 6-speed and 3.70 rear.. stock ls1 right down to the manifolds.. maybe I cant drive

 

I'm handicapped with a track at 5800' elevation, which adds a second to a 13-sec sea level car. I don't mind so much, though, as it's a level playing field. I just need to convert my numbers when discussing my results with low-landers.

(FWIW, my DD Berlinetta #1 with ZZ4-like 350 and computer q-jet, 2500 stall in a TH700, 3.23 gears out runs stock automatic LS1's up here.)

 

very nice there 88 350 tpi formula..im hopin mine would be around there..1989 Pontiac Trans am GTA..stock LS1 with stock 4l60e and stock convertor also stock exhaust manifolds...3.27 gears, full interior with A/C and heater, daily driver..

 

those here that just take info from what others have done
a registry would be nice though, i'll make a post about it.

 

From speartech.com (Note this car does have a very small cam which was probably negated by the fact that they retained the restrictive stock TPI air induction):

The following list of modifications were made to the car during the engine retrofit.
2001 LS1 engine w/4L60E transmission
ASP underdrive crank pulley
MAC mid-legnth headers
BMR control arm relocation brackets
Comp Cams cam .566-.566 lift; 222/222 duration @.050; 114LSA
Yank Thruster Pro 4400 torque converter
Weld Draglite 15x8 rear wheels with Hoosier Quick Time Pro 27x10.5x15 D.O.T. drag tires


I took the LS1 91 Z28 to Muncie Dragway on July 10, 2002, for some baseline runs.



I made 5 passes total.
#1) 12.060 115.25 MPH 1.800 60'.
#2) 12.151 115.06 MPH 1.873 60'.
#3) 11.920 115.14 MPH 1.729 60'.
#4) 11.926 115.35 MPH 1.754 60'.
#5) 11.921 115.36 MPH 1.741 60'.

 

222 with mid .560's lift isnt a very small cam. That aint too far off average DD type cams. Those cams still make 40 whp over bolt on only cars. Thats a big difference.

 

Roy Fender who used to ( or still does i dont recall ) formerly a third gen specialty shop owner ran 12.8 through there shops LS1/t56 swapped car. its was completely stock through maniflods and 3.42 gears iirc

It may have been even quicker but i definitely recall it was 12.x something.

Anyways as an aside who the heck would ever want to go through all the work of swapping an LSx into a third gen and the leave it stock? Makes no sense to me as a grand or three of go fast parts on top of swap costs can turn it into an mid 11 second monster that barely gives up anything in terms of fuel mileage or diveability.

 

Cam, stall and slicks though.

 

Having a TR224 myself, I thought it was a mid sized cam but according to today's LSX standards and tuning capabilities, it's considered a small cam. My 224 is a great cam and makes great power under the curve but I could have sacrificed some street manners for a larger cam to put me close to 440rwhp.

You guys have to remember Speartech's build was back in 2002 before HAWKS longtube headers (-15-rwhp) and Speartech established that the stock TPI duct was restricting power by about 10-15 rwhp. Slap the stock cam back in there and fix the above restrictions and you easily have the same low 12 sec 3rd gen LS1.

Stock Internal 4th gen are deep into the 11's, its not so hard to believe that the same or better can be attained w/our lighter cars.


OP didn't say anything about slicks? Who runs at the track w/o decent tires?

 

I pulled Berlinetta #1 on the track last Saturday on a whim (because my son was out there with his S10, and I can get into test & tune free this year). Just my normal highway 235-60x14 TA's (normally run 26-9.50x14 Hoosier QTP DOT's when I'm racing for real). I only lost .6 in 60' and 1.2 seconds in the 1320.

I'm just not into the thrill of seeing what a car will do in full street trim. It'll be tires for me for sure.

 

Just saying on stock heads, you dont need a big cam to make good numbers. I cant tell you how many times i've seen 237 deg+ cams on stock head ls1's only make 410-420whp when a milder 222-228 cam has made 400-410. Much more hp under the curve and you dont have to rev to the moon. Hell the stock LS6 heads with LS6 cam will do 400whp with full bolt ons and idle stock. Just something to think about.

On aftermarket or ported heads with good bottom end the sky is the limit. Those 230+ cams will come alive and make 450+whp. But I've seen good heads and mild cams also make 430-450whp. Thats a great combination.

But this thread is about stock motors in our lighter cars. Like i said, my heavy 99 TA went 13.4 at 104 with crap gears/stock converter. A decent thirdgen should be high 12's on weight and slightly better gears.

mild converter and slicks is mid high 12's all day long.

 

But for alot, it exactly the opposite. I have no desire to run a car with non DOT equipment. Its my driver, so why run it with open headers, and slicks, and race gas, etc.... Itll never be in that condition on the street. I want to know what the car can do, as it sits. Not how it will do after a couple hours of preparation.

And while I agree, if you are on a tighter budget, its better to swap, and then mod. And I like to keep things simple. I dont want to have to chase a bunch of gremlins that I think are from the swap, only to find out its one of the mods I decided to add. I want to swap it first, then start improving it.

 

Oh, my tires say "DOT" on them, for sure. . .

 

i was able to manage a 8.1 at the 1/8 mile on my stock ls1 / t56 set up
full 4th gen interior. complete a/c, stock cross member, 18 z06 replicas up front and some ets out back.

i had weak 60 foot times disregarding stock hp range and old shocks.
2.0 60s and a 89 mph.

i tried messing with my tire pressure & i noticed i was trapping lower speeds but better times.
my last run i launched at 3200 and i busted my rear end.
i have to go back with a right set up, better shocks for the weight transfer issue, launch a bit higher on a new stronger rear end set up c what it can do.

im looking towards the 1/4 mile

 

Yeah 1/8 mile is very boring. Its over too quick. 1/4 mile is much better.

 

those 4th gens are probably stripped and much lighter than our cars.

 

You don't need hours of preparation these days, the beauty of late model performance:

Electric cut-out = open headers.
Drag Radials = street slicks.
A good tune = Race gas
LS1 w/small cam = SBC w/ big heads/cam (w/o the surging and bad MPG)
LS1 w/ cam + nitrous = BBC performance (w/o horrible MPG and can be street driven)

Also, most people don't have all the parts for the swap so instead of buying OEM stock parts, they buy aftermarket performance parts(injectors, LS6 or Fast intake, cold air intakes, clutches etc.) which would eventually be replaced in the future.

 

True, but stock parts are a lot cheaper. LS1 intakes are like $40 on LS1Tech, stock cams are cheap too. (I needed a cam when I got my motor)

 

Dont get me wrong; I want sticky tires, high-flow exhaust, and a good tune.

Drag radials, 4" exhaust, and a good tune are okay with me, and street legal. And I like the aftermarket stuff too. Im in love with the Fast intakes and fuel rails, MSD coils, long tubes, and all the go fast stuff. Ive just never liked the idea of slicks. And cutouts arent my thing either.

Some guys like to squeeze every tenth out. Id rather lose .5 second, and know its in its street configuration. Drive in, run the numbers, drive out. Plus at the local track, the street fights dont allow slicks, and thats okay with me. Fewer oil downs.

Didnt mean to highjack, sorry. So mostly stock LS in a base bird should be low 13s, high 12s.

 

Same reasoning I used for my swap and why Ive got the 2.73s, manifolds, LS1 intake and stock LM7 cam. I knocked the rev limiter down to 5400 even though several guys are safely spinning them to well past 6300. I cant afford the down time for a potential problem so Ill leave some on the table in exchange for peace of mind with longevity

 

haven't even experienced the 1/4 yet.

??

 

13.22@112 2.3 60' bad tires full bolt ons, t56, 9" 4.11's 3120 pounds

112=low 12's with traction.

 

well...i'd tell you what i ran, but i had a small cam, converter, gears, and full bolt-ons with minimal tuning...

 

yeah some of your guys might say its crazy not to build these motors when doin a swap..i on the other hand, have already had a muscle car that i built up (carb, ill never go back) tuning was the name of the game..constantly tuning all the time, **** go old real quick..So i have this 89 GTA that my dad bought of the show room floor in 89..i build the tpi motor back stock, love drivin it around, but the car had no *****, 14.9 at orlando speedway proved that..I still want a daily driver, just something with some *****..so now that Ive got my completly stock (214 heads LS1..with roughly about 100h.p. over the tpi motor, ill know ill be impressed and no worring if the damn thing is going to stall out in traffic at five on friday..Plus that I can rev this motor past 6 grand is way better than spinning only to 4500 and thats it (TPI)..something about a motor when its around 6 or 7 grand thats just amazing...then again these are my opinions...to each his own..proud owner of a stock LS1 third gen

 

At Bristol, during the week, they run on Tuesdays and Thursdays. It has to be a street car, in street trim. No slicks, open headers, etc...

Alot of the rice burners complain because they say they cant go fast on drag radials, because they are made for heavy cars. So, the sandy vaginas are always crying. Its a safety issue, really. Those guys will neutral drop a stock trans, spraying a 150 shot of nitrous, just for the fun. They stopped allowing slicks a few years ago, when every other FWD car left fluids on the track.

No slicks now, and hardly ever an oildown. If you want to run slicks and open headers, then you have to run on Fridays, which is test and tune.
