89IrocZ350TPI

This weekend I am meeting up with this kid I know who owns a mint 01 Trans Am WS6. Its all stock with 31K orginal miles on it. I plan on buying one within the next year, so I asked the kid to run me just to see how i stack up. I have an 89 Iroc L98 with exhaust, headers, intake, runners, [both ported], hypertech chip, k&ns, gutted air boxes, 160 thermo, modded maf, air foil, tb bypass, afpr, msd ignition, re-mapped injectors, beefed alternator. My best run so far is a 13.4 at 100 on drs. I think i can pull on him in the 1/8, but after that the im not sure. I am putting down 245rwh and 340rwt on a good day..Thanks

your 1/8 mile might be quicker since your on drag radials and he is on streets. you'll outlaunch him. especially if you catch him sleepin at the tree and get out before him. he might not catch u.

it could be really close tho.. a good driver in the ls1 should do 13.4's and better. but street tires its abit harder to pull that off. if you get him off the line you'll hold out on him more than likely. but he'll be closing hard! lol

from a roll, no chance for you man. lol good luck

if you're runnin mid 13's you might be able to keep up with an auto LS1 or maybe a M6 with an "alrite" driver but if he knows how to drive he'll probably pull you especially after the 1/8

Cali Z

If its an M6 car then he should take you in the 1/4. Pretty much ever stock 01-02 WS6 I have seen run at the track have been in the 13.2-13.5 @ 104-106mph. Most stock autos I have seen have been in the 13.3-13.6 @ 102-104 mph. So ya you will get pulled on the top end, but depending how hard you take him out of the whole, will determine how long it will take him to run you down. Should be a close race imo.

a kid i went to skool with had an 02 TA with the 325 hp motor and a 6 spd...all stock, sept the 18inch rims(UGLY)...he fallowed me outa town one nite and when he went to pass at about 60kmh...i held him there and then started to walk away at about 100-120...and when we stoped and tryed it, it was same result...my moneys on you good luck

imo it all depends on the launch. whoever gets out of the whole the quickest will get it

zz4monte

If you launch it good you should win.My brother and I always went at it.He had a 98z-28 6 speed with pulleys,mti air box and exhaust and I would beat him in the 1/8 for sure but after 80mph we would let off. He ran 13.2 in the 1/4 with his mods and I ran 8.6 in the 1/8 with my zz4.If you race him at the 1/8 mile track you should win.If you race him at the 1/4 use your drag radials and hope he doesn't.That will make a big difference.A totally stock LS1 should run 13.4-13.7.I mean totally stock!!!!!!!!!! If he has any mods you will have problems.I recently raced a 2002 ss with exhaust and it was neck to neck.Those LS1's are Low 13's stock with the right driver.Should be a close race.Good Luck.
Your mph hour tells the top end story in the 1/4.Cali Z is right 102-104mph for the LS1. You need a good 60ft.He will be on your a$$ ready to pass after about 80-85 is my guess.

This is almost like the optimistic poll here: Is the Iroc half losing or half winning ?

Seriously though, if you were at an 1/8th mile track I could see caring. It's like your half way through a fist fight and you had landed more punches before getting knocked out .

ls1s at my track dont trap 102-104. add 4-5mph and u got it. SS with lid/catback went 109 on street tires. in the heat and poor prepped track.

Cali Z

well okay not all trap that high. Mine doesn't and it has exhuast and a few things. I bet you that SS was not auto and was an 01-02 year.

89IrocZ350TPI

Ive seen a few ls1 6-speed cars hit high 12's bone stock. Also my car may or may not have a mild cam in it judging by the way it idles. I'll make sure to post the results.

PHAT89TA

if you could recreated ur best run, i'll say u hold him off in the 1/4 mile, IF the driver of the ws6 has a bad launch. If teh ws6 driver gets a good launch, he's gonna pull u on top.

I drove a bone stock 02 WS6 6 speed at the track a couple of months ago.
The only seat time before my first pass in the car was the 100 feet from the staging lane to the water box.
First pass was a 13.5 @ 105mph since I hit the rev limiter at the top of 3rd.
Second pass was 13.20 @ 108
Third pass was a 13.12 @ 109.
This was on street tires and only getting 2.0 60' times.

If the other guy can drive, he should beat you.

your right...it was an 02 and a M6

zz4monte

That sounds about right.I asked my brother and he said he was doing 105 in the 1/4. I also asked him about the newer 02 ss I ran and I didn't realize they were rated at 320hp stock?His is 305hp.He told me the 02 has the LS6 intake?That might explain why he has several bolt ons and the new 02 just has exhaust and put up a better fight.
Here is the dyno difference between my car and his.

98LS1Z-28 6-speed. catback,pulleys,and mti airbox 3600lb car
308rwhp
332rwtq

87zz4 monte 3300lb car
271rwhp
378rwtq
Those LS1 make awesome hp with a few bolt ons.

01-02s do have the better Ls6 MAF and manifold, but i also heard they have a slightly different cam..something a tad bit weaker.

but all LS1's are in the neighborhood of 340hp. some factory freaks for sure tho, i have heard stories of this one guys auto 2.73 rear end camaro doing 13.2s at 109 stock

CrazyBear

wow so far im the only one saying you win the 1/4. I think you can just good luck.

zz4monte

LS1's make great power.I have raced many LT-1 F-bodys with almost full bolt ons and still out ran most but LS1's respond very well to bolt ons.400hp is easy to get out of an LS1 without even doing intake,cam,heads etc. All you need is full exhaust and computer work and your pushing close to 400hp.
Makes you wonder in 10years what will the power be like in American muscle cars right of the factory floor.Stock V8 Camaro's with 500+HP.Thats sick.
Off topic sorry.

Zepher

The bone stock 02 WS6 I drove at the track dynoed 323RWHP.
what does that come out to at the flywheel, 380HP? F-Body LS1's are very very under rated.

PHAT89TA

98 ls1 have different style heads(perimeter), bigger injectors 28lbs. 00-02 have better exaust manifolds, 01-02 have no egr. 01-02 have ls6 intake, and a slightly smaller cam. Some 01-02 ls1 been produced with the ls6 block. Hey zepher come down to cali and drive my car at the dragstrip.

PHAT89TA

DO u mean 400 flywheel hp or rear wheel hp. I've never seen an ls1 dyno over 400rwhp without touching the cam. Most i've see with stock internals with bolt ons and tune is around mid 360's rwhp

ShiftyCapone

Keep the race short and you could keep it even (assuming you run with your DR's). From a roll you are toast.


Just a few other points.

A stock LS1 on an engine dyno will make 380 to 390 hp.

A full bolt on LS1 (headers, lid) will make in the range of 340 to 360 rwhp and 400 and change at the crank.

If your L98 with full bolt ons made 245 than you have the stock cam.

zz4monte

400 Flywheel HP not Rearwheel.Like Zepher said "very very under rated."
My brothers dynoed 291rwhp stock. I don't think he lost only 14hp to the rearwheels.They are at least 350HP at the flywheel from the factory.

Steal on him at the kick and shut the race down just at 100mph or less. Then just say I saw no reason to keep going on I won!

89IrocZ350TPI

Well apparently he wasnt completlely "stock". When I met up with him this morning I checked out his car, he had an slp air lid, and a cat-back system. I decided to go anyway beacuse there was not money involved. First we go from a dead stop. I get the jump off the line. By 40 I had around 1/2 car on him then at around 70 he begins to walk away. We shut down at 100 where he had about 2 cars on me. After that we decided to go one more time from a stop beacuse there was no way i was going to have a chance in hell from a roll. This time i got the jump yet again out of the hole but held the lead alittle longer to around 75. After that same deal...just seemed like my car ran out of jucie and his car hit the sweetspot. We shut down around 95-100 where he had around 2 cars on me yet again. I'll get him back someday

Nothing a little gas couldn't solve.

I would say that you did pretty darn well. A well driven LS1 should be able to hang with an L98 right off the line and then just walk away from it. Sounds like you have a monster on your hands and there is no shame in this loss

zz4monte

Hell thats pretty good for only 245rwhp.No shame.I would love to run you.I think it would be close.What do you run in the 1/8 mile.

89IrocZ350TPI

R/T .647
60' 1.8
330 5.5
1/8 8.5
mph 79
1000 11.2
1/4 13.4
mph 100

zz4monte

Heres mine

60' 1.98
1/8 8.65
mph 81

I can't find the time slip right now.But thats what it ran.Your times are great for 245rwhp.I ran 271rwhp before we put roller rockers on it and my car only weighs about 3300 race weight.You did really well against that LS1!!!!!!!!!!!!Awesome times!!!!!!!!!!

No LS6 MAF, it's the same 'ol LS1. You're thinking of the intake manifold.

My trap speed was dead on with what you said when I was stock..104-105. Now it's 109 with some bolt ons. I still have no traction but I'll take it for a non stalled auto with some minor bolt ons

That's pretty much how it goes with a L98 vs LSx race. Good run. Do you have a converter or are you running a stock torque converter?

89IrocZ350TPI

i still got the stock tc in there.

TPI-Formula350-

sounds like you did very well againts that LS1

Dano 00TA

Damn, nice runs for you to keep it that close. You have a awesome running car there

Insaniac198

good runs
