lol that will be great, after the race pop the hood and see the confused look on his face

 

^^I'll just say it's a 5.3l with a LS2 Intake..

The LS1's do breathe extremely well..that is how you get your power to stay in the higher RPMs. Choke it out a little bit, and you have power now in the lower RPM's. A good example of this is the L98..meaty Torque, but hits a Brick wall at 5000RPM's.

 

my car had the stock converter so the m6 had the advantage....and the 60fts were the same...

and the times were close to the same every pass...no driver error either....both of us have over 10 years of racing experience.....

the point i was tryin to make was that when evenly modded the ls1 will still make more power....

like burnzilla said the lt1s were choked down from the factory...hell the worst flowing ls1 heads{97_98} flow 205cc ....

another example my car bone stock dirty paper air filter dirty mass air and worn plugs and wire ran .5 faster than another buddis 96 z a4 both cars had 2.73s and his car was in better running shape{low mileage car}

what i cant figure out is the lt1 and ls1 had very similar trap speeds and my et was.5 better....kinda weird.....

i dont know why these threads blow up every time....

 

Welp I might not have mah running as soon as I thought, but I know where Longview is now, I used to take 20 on the way to Palestine all the time.
LT1>LS1 *puts on flamesuit*

 

No, there are NO slow terminators out there.

 

I should just sell my LS1 and buy an LT1 if all it takes is intake/exhaust to out-run ls1s.

 

Out run? No.
Run with? Maybe

It really depends on what cars youre comparing.
You take an 02 M6 LS1 Vs. a 93 A4 2.73, which favors the LS1 as much as possible, its going to be an ***-whoopin.

You take a 95-97 M6 LT1 Vs. a 98-00 LS1 A4 2.73, you got yourself a race.
Especially when you add a CAI and Catback on a car thats choked out anyways.
If you can't swallow that, I don't know what else to say.
I think part of the reason LT1's have great ET's but lower traps is because they are 1/8 monsters, while the LS1's top end poise takes over after high speeds.

Fwiw, my 95 A4 pulled a 13.89 @ 99 mph when it was bone stock. ( besides new GTII Tires and Mobil 1 )
I don't think thats too bad for a 12 year old, 115K mile 2.73 A4 LT1.
( Well, at the time it had 88K )

The edge will always be for the LS1, however don't twist this into something its not because your upset. This is about the cars running with/close to one another, not total beatdowns.

 

Why are you comparing the worst version to the best version in each of your comparisons?

I have ran a cammed M6 LT1 and it was dead even and i'm lid/exhaust. I've ran other m6 LT1's with unknown mods, probably just exhaust and taken them down pretty easily. About how I would take down a 99-04 GT.

Actually when my L98 third gen was bolt-ons only I was hanging with LT1's, and it was only like running 14 flats approximately. At the 1/8 mile I beat them pretty much everytime in my L98 back when it was running 8.9's.

How are LT1's low-end monsters? I've driven a few LT1s in my day and it doesn't really feel much different than an LS1, except slower at WOT.

You guys have seriously got to be running some dogged *** LS1s, 2.73's with 200k miles on them and traction control on. I've never even had trouble with an LT1, except from a dig one time cuz I spun all the way through first and halfway through 2nd then proceeded to just roll on by him.

 

To compare them.

Sounds about right.
Cams don't do **** compared to what they do for LS1's.

There was a vid/kill story of a Full bolt on LT1 racing a cam only LS1... race was very close.

What is your Et?
Did you race from a dig?
Highway kills would be much easier for your LS1, but from a dig you might have your hands full.
I have drove and raced a 2V GT, and it surprised me, but my A4 walked by it pretty good from a slow roll.

Listen, I don't want to go back in forth, you are right that an intake/exhaust LT1 will most of the time lose to an LS1, but if you only have an intake/exhaust a full bolt on LT1 is enough to run with/maybe walk you from a dig.
A strong, good running M6 LT1 with an intake/exhaust may just surprise you.

 

Don't get me wrong, I was actually considering buying an LT1 before this car. I was in the same position when I only had my L98 with the LT1 guys telling me I could never run with them with only bolt-ons. Well I out-ran them with bolt-ons.

I've just seen too many LT1 guys(not saying you) say that they beat LS1s easily with only intake/exhaust. It just simply does not happen, unless LT1s are different elsewhere...full bolt-ons is a different story, I can see that happening.

 

I'm pretty sure there are quite a few stock LTx cars running that good or better stock... that's 99-04 2V GT territory.

 

Not at my track... try 9.0-9.2 for lt1's, 9.2-9.5 for 2v gt's

 

Here's a link to a little photoshoot of me and my older bro's car. He loves 3rd gens.

https://ls1tech.com/forums/multimedia-exchange/723954-20th-ann-l98-iroc-z-lt1-camaro-pics.html

It has Twin K&N's, Duals and a JetChip.
He can run with me till about 70 mph, then after that I start pullin like a train.
By 110mph he's pretty far back...
Torque'y sumbitch's they are though... I love the GTA's.

Its cool man.
Well, the stock exhaust manifolds are bricks for LT1's. Basically the entire intake and full exhaust system is terrible.
Like I said, its not an excuse, but an LT1 with a CAI, Headers (even shorties...ANYTHING but the stock manifolds) and Catback, with gears will run with a stock and lid/catback LS1.

I have seen it alot.

 

That's pretty shittay... I ran a 9.3 in my '98 GT (exhaust) first time at the track...

 

It probably would happen, I just am unsure about the mods of the all the different LT1's i've raced. I would ask them but usually they just mean-mug with their windows up or turn off and give me the finger. One of them asked me if my car had an LT1 too??

Well i'm already saving up for a tr224/ported 243 combo so I won't have to worry about that anymore, but i'll probably get headers/new catback before I do any of that. I'm also considering some different gears than my 3.42's.

 

my friends 96 GT with xpipe and exhaust runs 9.7's Lot of them run 10's

 

Damn... you must have a REALLY high DA at your track. My stock Integra ran a 9.7 @ 74mph

 

Just for comparison's sake, at my track here in cali I've never seen a bolt on LS1 trap better than 108, and the fastest bolt on LT1 I've seen here is mine at 105.6, that was with headers/cai/tune, I feel there was more in it but I've got heads on it now..

There are a ton of factors to determining what is faster than what. What it largely comes down to (after displacement of course), is intake/head/exhaust flow, when talking about bolt on cars.

LS1 intakes and heads flow much better (stock vs. stock), and we've already established their better exhaust. Although if you fix a couple of those things LT1s are pretty close. It's not uncommon to see LT/CAI/Tune LT1 cars putting down 295ish rwhp and running 12s with tires.

Once heads/cam swaps get involved though, whoever brought more money usually wins.

 

yeah if your ever in the area let me know and ill let you know whats going on, last few times ive come up to DFW havent been in my car but i plan on bringing the car up there some later this summer need to get some locals to show me around .... i dont know how much longer its going to take to get mine running either got to figure out what the problem with mine is first hopefully its something pretty simple

 

From an LT1 guy, I can't see an LT1 beatin or only losing by a car w/ just intake/exhaust on the LT1. From my experience and general consensus of most LT1 guys at camaroz28.com. Here is what it takes for an LT1 to hang with and maby pull a car on an LS1..Given perfect driving by both parties.

LT1(95-97): M6 CAI,Headers,catback,cutout,1.6rr's,PCM tune. This setup should put an my lt1 near 300 rwhp. Right on par w/ an ls1. Now come 120+ mph I can see the LS1 pulling away still. On the street I'd say an A4 would need a stall.

I used to own a 93 a4 formula and now have a 96 m6 and from owning them both at the same time for a month. The 96 pulls soo much harder. Then again the 93 had 100k and the 96 only 30k.
