I was wondering if the "newer" ls1 cars were really faster or if it was just a myth. Both seem to dyno the same.

"Beginning in 2001, the LS1 received the higher-flowing intake from the LS6 and a milder camshaft to keep power at the same level"
Also the fastest ls1 car I could find was a 99 camaro and it ran 12.8.

Get a 99+ the PCM is better for tunning. The 98 PCM has issues that the 99+ did not.

Interesting. I already got a ws6 and am not in the market for another one. From what I have seen the 98-02 all seem to dyno in the 300-325 hp range stock. Best I have seen was 321 from a 99 camaro Z28.

My friend's bone stock (except boxed LCA's and relocation brackets) 02 SS w/ the 335hp package ran a 12.64. Very impressive. It's the fastest stock LS1 that I've seen thusfar. If I had read it like you are reading it, I would call B.S. but I saw him run it and I drive the car frequently. That time was with the stock lid, air filter, etc. That factory LS6 intake does pretty nice things...
edit. He's also an exceptional driver. On that particular run, he pulled a 1.7 60' on Firestone Wide Ovals. Those are drag radial times.

Thats nuts damn. No doubt the ls6 intake is better, but I read the 98-00 had a better cam to keep the power the same. Need an ls1 expert to explain cuz im confused. My friend is tryin to tell me an ls1 is an ls1. His 99 SS put down 340 with just an exhaust, air lid and tune. Maybe it was just a happy dyno. But I did see the sheets.

I've never heard that cam theory. I heard they were running out of LS1 manifolds, but they had loads of LS6's so that's what they got. Also, 01-02's with the LS6's had no EGR. There is no provision for it on the LS6 manifold.

MikeWS6

There is a thread on here with every ls1 fact known to man lol. I read it on there. I believe its a sticky.

the cam is a tad bigger.. it matters aboout as much as an ls6 intake..

ls6 intake on a bone stock car is only good for around 10rwhp max (and i mean nothing changed but the intake)..

now if your telling me that makes a difference, they are faster.. if not then you have my answer..

an ls1 is an ls1 is an ls1.. i ran just as good, same as, and some that had better times as me when i was stock.. regardless of year or trans am/camaro, ram air models or not..
when i had a lid and LM exhaust otherwise one stock (full weight to the spare) i ran 8.4@84.. thats in a 98 base model trans am a4.. i have seen worse, as good, and better times from many other years and models..

i have raced quite a few of other years.. m6 and a4.. base models and performance packages.. etc etc etc.. ive never lost a race to another fbody/gto/vette..

an ls1 is an ls1 is an ls1.. that is in a stickey somewhere around here.. misinformed people will disagree with this..

MikeWS6

I thought the ls6 was only good for 5rwh. Yeah I agree an ls1 is an ls1 thats why i voted for it. Unless someone has soild proof my mind will not change.

nah, they should be good for almost 10.. but thats it... on a H/C car you could see around 14-17rwhp... but thats pushing it..

now if you ask... **SHOULD** 01-02s be faster.... in theory, yes...

are they.. no..


no one will change my mind, period..

just like 01 zo6s are supposed to be "slow" compared to other years.. should they be? yes.. are they? usually not..

MikeWS6

Well in theory I would say they shouldnt be cuz of the smaller cam. Not an expert but it seems they level each other off..

An LS1 is an LS1

This has been gone over so many times that is should be the header at the top of the Site.

DCsLS1

an ls1 is an ls1 whats better about 01-02 is everyone is going to get an ls6 manifold anyway so its nice to already have it. Although there is a video of two brothers on here that both have ls1's with the same mods but one has an ls6 mani and the other an ls1 and on the races they were about dead even but the ls6 guy would always start to pull away up top.

the cam specs are so close its stupid.. just like an ls6 not really mattering on a stock car..

you could take that ls6 off and swap it though and i bet the outcome would be the same..

MikeWS6

Yeah probably. Some are just faster than others from the factory. Or one could just have a more experienced driver.

the lower rotating assembly is essentially the same from 98-02. only difference is that 01's and 02's had the ls6 intake manifold giving it an extra 10 hp as stated on the window sticker.

99-02's had a better pcm than the 98
98's had a much more lobier cam
heads flowed practically the same with only minimal differences

i would not say 01's and 02's had a better engine. the difference between 305hp and 315hp shouldnt sway anyone from buying one car over the other.

MikeWS6

98-00 ws6/ss models were actually 320 and 01-02 were rated at 325.

ram air does not make an engine 'better'. it may add 5-10 real hp at 120mph, but it sure as hell isnt going to make your engine 'better.'

MikeWS6

Did I say it did? No I told you what it was "rated" at. Which they all probably should have been rated around 350bhp. All the ls1 ratings were bs for the 98-02 f bodies.

Yes the older LS1 have larger cams but the newer Ls1 cam out with 241 heads and LS6 Intake but ofcourse the smaller cam. But If you ver plan on upgrading cams on the newer cars it will be off a better platform. Better flowing heads and intake
