hey guys....i got a quick question...this morning i traded in my 1996 Acura integra (winter car), and bought a 1998 trans am! i still have my sweet :hail: thirdgen. but i want to know which would win in a race. the t/a the ls1 6 spd. but is completely stock. my mods on my maro are in my sig. i was thinking that the trans am will take it but i havent driven the t/a all that much so im gonna get my good buddy who also owns a thirdgen to drive my maro(and yes he can drive) anyways about an hour out of town there is an abondoned air strip where we usually like to play around with our cars. if we run who will win?and by how much? thanks alot its much appreciated.

 

From what I seen, most stock Ls1's are around mid 13's. It will be close, but my moneys on the 3rd gen.

 

84' L69 HO
5 spd 3.73's
heddmen headers
3"exhaust "X" pipe
to flowmasters (no cat)
plugs and wires
k&n air filter
XE 256H cam
best time at track= 13.3@104.6

Huh? What else is done to your car thats got you running low 13's? By looking at your sig one would come to the conclusion that you have little more than a cam and headers in/on an otherwise stock 305 (No intake, heads, n2o, motor swap).

If your 1/4 time is real than I guess whoever's willing to push their car the hardest is going to win.

 

i dont see how you hit 13.3 on those mods...im barely there and i have considerably more mods. but i guess if you add in the factor that i cant drive, then i guess thats about right...

 

Thats bs. 104 mph even spraying I would be skeptical.

 

I was thinking the same thing. Those mods don't seem to add up. If the 3rd gen is not putting 300 to the wheels then say goodnight, because the TA will own that 3rd gen bad. Even if your ET is a bit quicker that LS1 will run you down fast past 100mph.

 

that does sound pretty fishy.....a stock L69 runs 15's flat....but it seems you would have to have some pretty descent mods to dip down into the 13's...

 

13.3 @ 104 might beat the LS1 out of the hole, but the LS1 will start pulling hard once you get to the 2nd 1/8 mile. Should be a driver's race.

My 98 w/ nothing but an airlid and catback for "power" mods ran 13.5 @ 109 MPH. The 13.5 isn't that impressive, it was on stock RS-A tires and bad track prep (2.3-2.5 60's all day). But 109 MPH is enough for mid 12's w/ traction. Also, the 109 mph is w/ a 280 lbs driver and the spare and jack still in. You take the spare and jack out and have a 180 lbs driver instead of me, and it is around 110.5 mph. Not bad for 2 very simple mods.

 

if your LS1 doesn't hit low low 13s stock their is something wrong. i say if you run 13.3's in the 3rd gen, the 4th gen should take it, expesialy from a roll.

 

That is the best thing you could have done. I bet its big change going from that 4 banger to that T/A. I have always loved the 4th gen T/A. Good trade though.

 

You're either sandbagging with the mods or lying poorly. There's no way you're trapping 104mph on untouched 305 heads. Maybe 94mph, although I'm not sure that's attainable without spray. So with that in mind, a 6 speed LS1 car will absolutely destroy you.

 

Just going by what mods you have posted, that LS1 will tear you apart. And if we were to go by your 1/4 time, maybe you forgot a few mods to post, even then you might lose. Maybe up to 70 you would hang with your low 13sec timing, but after that the LS1 will slip away.

Its a loss either way, especially if those are the only mods you have.

 

I run 13.1's at 109 with the mods in my sig and I BARELY beat LS1's from a roll. From a stop, if I can get them out of the hole, its usually up to 2 lengths depending on the driver.


*Edit* Realized my sig doesnt have the mods anymore.

LT4 H/I/Hotcam
1.6 rockers
Heddman shorties
MSD ignition
3.42 gears

 

And all you'll need to do is an exhaust, lid, and some sticky tires...

I ran 13.0 @ 111 on a 2.1 60' with those mods. Once I actually heat up the drag radials, it'll be 12.70's or so

 

this is kind of off the topic but starting in 1990, the IROC's *then the Z28's from 91-92 with the 5.7 TPI's) came stock with 345 lbs of torque....and the stock 5.7 LS1's came stock with 340 lbs. Why is it that the TPI's have more torque? Just curious...hope it's not a dumb question....

 

I love that you traded that ***** for a REAL car, good job!!! As far as the race goes, well let's see I think it would probably come down to who the better driver is/was!!!

 

Well, to put that in perspective...

I dyno'd 329 ft/lbs at the wheels STOCK with 87K miles.

I'm not sure what a stock L98 is going to put down, but something tells me it's not going to hit almost 330 at the wheels.

 

then how come in the specs it says so? is it because it's not listed as on the rear wheels....?

 

No car has ever been rated at the rear wheels. The numbers you are looking at are at the flywheel.

You can compare numbers all you want, but a L98 against a LS1 isn't much of a match after the LS1 hooks up.

 

The L98 gets about 214HP/312TQ.

 

Not bad at all.

One thing to consider...

Although the Z28 is rated at 310/340, we all know that's conservative. The vette is 350/375, so my dyno of 306/329 is right about where it should have been stock. +15% driveline loss is 352/378... I say that's pretty damn close

 

I realize that....

 

sorry about that guys i thought i had updated my sig. a long time ago.haha sorry. the other mods on the thirdgen are as follows:750 cfm,holley alum high rise dual plane intake, world products ported S/R torquer heads, manely valves,elgin valve springs,new badger pistons and rings,elgin lifters,push rods, and rockers my own version of "ram air", some nice sticky tires i lent, and a adjustable 100 shot of n2o.
and might i add damn!....having that 6spd in the t/a is sooo nice!

 

I'd say that makes a difference....lol

 

I'd say it could go either way. If you're runnin 13.3's and the TA should run right there also.....it'll be a tossup.

Try running a couple times and it'll prolly go both ways.

Oh yeah, Way to go getting the TA

 

it will be a good race, untill you mod the :hail: LS1. i read over on the LS1 forums and i saw that... this guy had; a 6-speed 99 WS6 w/ cut-out, K&N, and a SLP lid. he whent, get this, on NITTOS 11.97 in the 1/4 mile.


i'm not saying the LS1s are better, but they have major potential. so good job geting a LS1.

 

with thoes times, 100% dirvers race. Ive seen LS1's run the gambit from 12.7 to 14.5. Average will run low to mid 13's. Box stock 98 might run more twards the mid to high 13's. All depends on miles and so forth. Im gunna give the third gen the nod on the win, but it could go either way.
congrats on the buy too! How much was it? I know later 4th gens are becoming cheaper and cheaper. I wish it was the case for insurance rates.

 

That is the biggest load of I've ever heard. Either he meant 12.97 or he has a cam/gears that he's not listing... They have potential, but not that much!

 

Ill end this right now...my dad has a 2001 T/A WS^ and he ran againsta an 89 Gta and sad to say, Gta at Dust...The 4th gen just blows past 100 w/o blinking..


Not related but for fun my dad raced my bro's 91 t-bird..it was a laughing matter...T/A hit 145 and T-Bird hit 115 on the highway..not real drag i guess..


-1-MEAN-T/A

 

Maybe he just had a good run with perfect conditions. There are numerous guys running around 12.2 or less with similar mods. Most have headers though with the cut-out and all of them had drag radials.

 

belive what u what, but it happened, their are slips at the LS1 forums...

http://www.ls1.com/forums/index.html

go to:

LS1.com Forum > Performance/drag strip/AutoX > 1/4 & 1/8 Mile Times & Dyno Information > WOW! Car just keeps getting faster without any new mods.

(WOW! Car just keeps getting faster without any new mods.) should be near top of page 2 of the (1/4 & 1/8 Mile Times & Dyno Information) page................ THANK YOU.

 

well, back on topic, did the race go down???

 

Here's a better LS1.com link, one I created just for you

The truth

 

Yeah, as much as I love LS1's there aint no way they're gonna go 11's with the mods we're talking....unless alot of weight was stripped out of the car.

 

What do you expect? The GTA runs about 95mph and the TA 105mph or better...

 

the last year of the lt1 was 97 so you have an ls1 but i would choose the camero

 

I don't know if you mean engine mods only but a friend of mine that is a member of kyfbodies.org said there was a guy with a LS1 Camaro that had a throttle body, 4.11's, torque arm, relocated LCA's, slicks, and some other chassis mods go mid 11's. The engine was otherwise stock, but the chassis was highly modded. If the interior had been stripped he didn't mention it.

 

You know i go to the track and see them run and they just dont run as fast as they do on the internet....

 

ok sorry it took so long to post the results....we ran twice last night out at the old air strip. once with the spray and once without. i was driving the t/a and my buddy the classic 3rd gen.
i had a friend start us off, right off the line the 3rd gen took me!he pulled about half a car length until i hit mid second gear, i started to pull on him and by the end of the race i beat him by just about 3 car lengths...that run was without the n2o. i was having troubles getting traction so the second race we went from like a walking pace roll, almost immediatley i pulled on him it wasnt until 3rd gear he pulled hard on me til the end...with the thirdgen spraying in the second race by the end, he beat me by 1/2 a car length.
it was 2 good races!.....either way im living the life i dreamed of. lol i cant wait to mod the ls1!but long live the :hail: thirdgen!
does anyone have advice on what to do next?!
thanks again.

 

Next?

Lid, catback, subframes, and drag radials. That should keep you happy for a little.

 

Sounds like some good races, as far as mods for the ls1 check my sig. They're keeping me happy.....for now at least

 

Nice 84'Camaroboy.

As for LS1 mods, a lid and cutout and/or catback are a BARE MINIMUM for these cars. And I think a good shifter, such as Pro 5.0 or Ripper are a MUST for an M6 as well. Also recommend 4.10 gears w/ the M6 (probably my next mod). The 3.42's just don't seem like enough for the stock motor. Drag radials will help you get off the line. This should be plenty for 12's. After that, longtube headers. I think LS1's beg for cam swaps too, at least a 224/224 Should keep ya busy for awhile.

TPI motors create more torque due to the intake runner lengths. when mathced correctly with a cam, considerable amounts of torque can be achieved. the longer the intake runners the more torque is possible. thats if no other component in the motor hinders the torque. to get more in depth, the longer the runners, the faster the air will move through the curve. faster air, with correct timming and fuel mix will get lots of fun...
