Mods to beat a LS1 Trans Am?
 

What type of mods would I need on a stock FD to win over a LS1 TA? One of my friends just got one and he's talking shit. Friendly rivalry and that shit. So what type of mods do I need?

not much... they should be pretty even stock...
is the LS1 stock?

with a few bolt ons you should be able to take him in a straight line, and absolutely slaughter him the the twisties

Very stock. He's test-driving an auto. until Sat. and then he's ordering a 6-speed. Thanks for the quick reply.

as far as i have delt with i just needing to make sure i was in gear before i dumped the clutch off the line.

yah, I recently killed a ws-6. Stock. Well, unless the strut bar powered me a bit ;)

we must have some bad ass ws-6 cars here in mississippi, cause i was dead even with them at the drag strip with ALL of the bolt ons...including an intercooler....maybe my car was a sack of shit.....who knows...

Guys the ones you racing are prob Lt1 which run about like a 3rd gen stock. The ls1 is much faster stock. Get a intake, dp, catback and you'll be set to kill him.....as long as you can drive decent

That's the most important thing besides mods....:cool:

i know the difference b/t the ls1 and the lt1. 10lbs of boost and a dp might keep you up with one on an interstate pull....

they are not god-like cars, but should be given respect. a simple 100shot will keep most fd's in its rear view...

just think about them if you put 4k into one like most of the fd boltons will cost.....mti heads and cams pkg with some super roller rockers and exhaust on any ls1 will run high 11's on motor....

i am not sucking these cars off, just stating that they should not be bashed or understimated for the sake of a forum...

signing out from "F-body" country

I havent seen a lt1 with those mods alone run 11's.....maybe low/mid 12's. Contrary to popular belief its not hard to get a FD into the VERY low 12's. All you need is a intake, full exhaust, PFC with base map runing 12-13psi of boost. Thats what I did anyway, with the rest of the car bone stock and a set of Nitto DR's. As a matter of fast that very race I ran a LT1 with a full exhaust, intake, gears, and either a 100 or 150 shot and he ran a 12.4, with close to the same 60 foot as me.

I know a LS1 with those same mods you mentioned and a s/c with 13lbs of boost and he's running 11.2, without that 13lbs there is no way he would hit 11's.

Not saying it isnt possible cause different parts of the country are different due to weather, ect but I've never seen it here.

STEPHEN

Yeah Firechickens can be pretty fast in a straight line. Thats about all they are good for. :D Watch out for the ones with juice and mods though!

yeah, i am really referring to the ls1 motors. they are strong. i know that the fd's can get into the 12'easy, but i have not seen i tin person. i am one of 2 fd's around here, and there is no local tuning or support. however, i am waiting on RP to get the pfc back in stock. then i will have them tune it. then, i am going to use a set of MT e/t slicks on bogarts for the run. then turbos to your buddy bryan at BNR.....then..............bust that dude in the t/a!

with just intake, y-pipe, dp & cb I can run with an LS1 vette... my buddy and are bout the same driving skill, and he usually takes 2 of 3 from me. the LS1 f-bodies are anther thing... they have less hp and quite a bit more weight (like 3500+ lbs). in the hands of the right driver, a LS1 f-body could take a FD, but I agree with most of you... it is close enough to come down to the driver....

I find this funny coming from a guy who got killed by an E Class Benz cause he forgot to downshift... :D ;)

ok bolt on, any part that can be put on without programming/tuning. so what is non bolt on other than ecu, like injectors and shit?

Dood, be careful man! I have been banned from the kills section for awhile now b/c of that exact same term of endearment :D

Bwaaaak Bwack Bwack :p:

Well i just raced a 2002 ws6 tonite, twice. we hit it from rolling start in first and by the time i shifted into third the front of his car was at my door so i was pulling but not by much. he had jsut dynoed his car too, and did 327 to the ground. i think if we had wound out 3rd gear i would have kept pulling but i was a pretty good race. my mods are as follows intake, dp, mp, cat back, ecu non-seq. he had a computer and thats about it, i believe. so thats my side of the story.

Dang, you got me :D I didnt get killed though, just never downshifted because it aint no race ;)

Hmm. That's weird. I absolutely *raped* a WS6 the other week. It's posted in the kills section (the thread that got me kicked out of kills :) ). That was a highway punch, though.

There aren't many things in life I get more enjoyment out of than sucking the paint off of the doors of the poor unsuspecting Vette, Firebird, SS owners around here. V8s rule Texas, indeed:D

The only 2 experiences with LS1s I've had were
1) I was breaking in my new engine - couldn't run
2) My wife was in the car - couldn't run:mad:

Both LS1s (one was a Z28 and the other a newer WS6) revved and I just sat there looking stupid:mad: - but when they dropped it, they both took off pretty quick. They are fast cars and don't think a stock FD could come close to one. I know LS1s run very low 13s and even a prime stock FD can only run 13.5 at 101 mph.

the only other thing it could be is a friend says he had a 4.10 gear installed, could that have been a problem?

That would make it much quicker. I have a friend at work with a Firehawk limited edition TA. We've run twice. He claims it's bone stock but he's been known to hold back a thing or two. I beat on him a bit. Three to four lengths after a street measured 1/4 mile.

He runs 8.20's in the 1/8. We don't have a 1/4 mile strip within 100 miles. I've seen the timeslips. I haven't run at the track yet. I'm waiting on a clutch at the moment.

My mods at the time,
street port, dp, mp, cb, intake, remapped ecu(13.5psi), short shifter, dbar's non-seq mod.

Oh, he did use ET streets on the 8.20 runs.

He also owns a 2000 Camaro(LS1) that runs 7.30's with lots of mods and he's squeezing.

I can hold my own in my town but what gets me is that every time my friend's race a v8 the v8's never use there 150 shoot of juice, but whin i race them thay always tend to use it. But thats ok, I have been racing them only with a downpip, catback exh. and intake now i got my pfc and fmic on the way.

What are you guys using for shift points? What revs?

What is the best standing start? Hold about 2500 rpms then go?

At a standing start and at a place with good traction i hold at 5000 rmp's, if the place where i race does not have good traction i will hold my rpm's at 3-3500 and i shift at 78-8000rpm's

A stock FD vs a ls1 T/A. The FD is going to take a slight whooping. I raced a 2001 WS6 T/A the other day on the highway. As I could see he had exhuast. We punched it from a 50 mph he jumped in front of me I had to slow down to keep from hitting him so I knew I was pulling on him a little. But this thing never ran out of breath all up to 140mph I only had a car maybe a car and a half. This really suprsised me. I thought that we would just be even, even him pulling on me. The ls1's are nothing to laugh at. They can clock low 13's even some into a very high 12. That vs a stock FD of lets say 13.7. Your going to need mods to beat a ls1.

I have both a 94 rx7 and 98 TA 6 speed.
The RX is stock and the TA has bolt ons.
Off the line the TA wins.
From 80 to 100+ the RX has the advantage.

^^^this is what i have been trying to say, earlier in this thread. i am sorry to say that there is NO DESTROYING a ws-6, especially with a stock FD. maybe a car or two on the interstate pull, but that is not destroying anything.....stock ls-1 cars have seen times as low as 12.7 (ss camaro). this was in a GMHTP mag, and the driver was a pro drag racer....someone like john force. well anyway, the car dynoed @ 327 rwhp, and was BONE STOCK...........i sure wish that i could add a ws-6 friehawk to my garage......

Id love a firehawk. 1 of my favorite domestic cars. An ls1 firehawk stock will knock your socks off.

finally another member who ain't afraid to give'em props. i love that metallic rusty-bronze color......beautiful, and fast. i will say though, they are best for cruising & straight-line runs. not cornering.....unless well equipped...

"On the dragstrip, our Trans Am ripped 0-60 mph in 5.0 seconds and cleaned up the quarter mile in 13.5 seconds at 107.4 mph"

"...by pulling 0.84 g on the skidpad"

I guess the difference was in my shifting.

BTW, those firebirds are quite the machine on the straight line, but I have a little bit of contact with people who have raced them competitively, and if you want to have any handling performance out of them... you better just strip it down and start from the bare body. They do lay quite the strip though haha.

well good now i dont feel as bad about not being able to pull him that hard. he raced a guy with a ss camero 2000 and whopped him last nite so i dont know what he has done to the ws6. i guess its the 4.10 and computer.

this is being discussed on the LS1 forum right now, actually:
here is the link

Hey Street King, where are you in TX. We can get together and admire our cars...

Lets get something straight, all 13brew's run different due to mileage (compression) and maintinance and there are some freak LS1's out there too.

The first week I had my car it had 6k miles on the motor and I ran 2 stock WS6 LS1 TA's on the highway, I put a length on one of them and the other hung right with me.

Stock vs stock I would say they have an edge but if the rotary would have the same milage as the LS1, it would be real close.

Re: Mods to beat a LS1 Trans Am?
 

Well, based on my own street experiences (since some people don't take other's seriously without a timeslip), I would have to say depending on what year the LS1 is and how good a driver he is, also if it's an auto or M6, it would be close. Given both are stock. Keep in mind 01's and 02's have been known to be stronger than earlier year's as well. However, I have raced a few in my time and this one in particular with a muffler and an intake blah, blah, blah wasn't that close. I know what an FD is capable of and believe that with an intake, catback, dp, more boost and ecu, you will be a handful for him.
Don't be surprised if he takes you though with you being stock.;)

We should run sometime for fun. I have only 2 significant mods on mine. So i'm not stock but I can at least cap my cutout.

That car for your avatar kinda looks like the one a friend of mine got the other day. He traded his S2K for it. Supposedly it puts down around 400 to the ground. Haven't raced yet but if it's true, he'll slaughter me.:D
