F-Bod LS1 vs. C5 LS1
F-Bod LS1 vs. C5 LS1 What are the principal differences that make them make their power at different RPM and make the C5 LS1 have the slight edge?
And another question...in 2002, roughly 25% of all F-bods got the LS6 motor instead of the LS1 by accident, but with no real performance difference. Why is that? Is the LS6 motor just a reinforced version of the LS1 with a better cam?

not an ls6 motor, and ls6 block and intake. BIG DIFFERENCE! ls6 motor is in the z06. I wish we got that! The Fbodies have a more restrictive exhaust and lid, also GM is dirty and just flat out lied some times about horse power and torque. i have a c5 vert and an SS, and i personally think the SS is faster now that i just put a lid on it. The c5 also has amazing suspension/handling when compared to an fbody. weight also is a factor.
Weights one factor, but the fact that GM could downplay the HP #s to their liking is another. Seems they've started this "lower quoting" # game again, which is kinda cool. I just think to a certian degree that GM wanted to be able to say the Corvette had the "most power" and all that out of those engines, then they could de-tune the Fbodies just a tad, but really make them just as equal in the performance department.

Well that was 98, and a lot has changed since then, but I have to laugh at the Mustang GT numbers! Must have sucked to own a Mustang GT back then..LOL!

I read also, and talked to a few shops, and they say that F-Bodys, actually can launch better with the solid axle when setup right. The Corvette has always been traction limited, with the spinning tire syndrome, plus look how much more performance the Corvette can get with just some different non-runflat tires! At the track I see equal modded corvettes and f-bodies running neck and neck!
But isn't it funny how everyone compares their car to the Corvette! What does that say? Hey my car is faster in the quarter than the Corvette, my suspension out handles a Vette, my top speed is faster than a Vette. It's nice to have the car that everyone wants to compare to yours. In the stands, I always here people booing Vettes, and hoping the other car can beat it! It is a major envy thing, but its funny, cause anyone can just wait and find a garaged older model for $25000 or less. And it don't cost any more to mod the Vette than the F-body!

My dad bought a 1991 L98 coupe brand new after the Gulf War. Its 100% bone stock, and sometimes its funny how some of the ~$30k cars of today cant keep up w/ it.
With equal mods, it'll come down to driver. Of course, everyone who's raced knows that. The power #s swing both ways, i doubt there's 100% conclusive proof that Fbodys mod for mod out-dyno vettes, and the opposite is true. The Gen III family is a stout platform, and obtains great #s no matter what its in be it Fbody, Vette, GTO, Silverado/Sierra, CTS-V and the Holden's.
We all support The General, so its not like we're falling too far away from each other. Be it Corvette, Fbody or whatever you got...lay a lil rubber down, and just keep up the good work!

I just traded my 2001 camaro SS SLP #4204 for a 1998 Corvette C5. In 2001, the LS1 had the LS6 intake manifold, exhaust manifold and block. With 900 miles and a K&N air filter, the Camaro dynoed at 317 rwhp and 323 rwfpt. With the 17% rule that's 370.89 and 377.9 at the flywheel respectively. That SLP package claimed 345 bhp, so that was a good pull.
The Corvette revs to 6500 rpm instead of 6000, and obviously has a weight, and weight distribution advantage. On track days, the Vettes seemed to hold a 0.3 tenths advantage with like mods, but a lot of that depends on drivers. My SS was pretty heavily modded; for how I had it built, it was a Z06 hunter. (And I had a few come try to get some too)
I really enjoyed the SS, but my goal was to have a C5, and I'm VERY happy with it. The LS1 and all LS6. LQ4, etc. are great motors.

I owned a Z28 and now own a Z06, the truth of the matter is there is no comparison!
I am a total gm freak and like and respect pretty much all cars (even 1 or 2 fords) but this car is by far the fastest and has the nicest ride qualities out of any car I have ever owned (I have had 5 Camaro's from early 70's to present) I plan on getting another old Camaro in the future but hope to keep my 02 Z06 for a long time!
Stock vs stock every dyno session I have been to the Y body always pull better #'s than the F bodies-it might be in the drivetrain?

I have heard that T56 cars actually only lose around 13-14% in the driveline to the wheels with stock gears and 10 bolt. Not knocking you at all, because that is still a great pull especially stock. Just sayin its probably more in the range of 364-368 FWHP and 371-375 RWTQ. Which equates to about 50 more than me

A couple differences are,the c5 auto has 2:73 or 3:15 gears,i think the f-body auto has 3:23s..correct me if i'm wrong.
The run flat tires hurt traction for the c5,with normal tires i would say they launch better than f-bodies,at my favorite vette site,theres a whole bunch of 9 second c5 videos,no wheelie bars or parashutes,and very little front lift or rear squat.
And the c5 PCM has a more aggressive program,which can actually hurt,i run 92 octane (highest available here with using the 100 octane "cool blue" at 8.99 a gal)my PCM is always in the low octane tables,21* timing across the rpm range.I have to add octane and pull fuses 16 and 23 to reset when i'm at the track.Then i'm at 28* timing thru the rpm range.Mines an auto with 3:15s,and i have never lost to my buddy's very cherry,99 anniversary car6-speed,long tubes and exhaust,whisper lid and QA-1 full coil overs and sub frame connectors.I have a halltech fresh air intake and gutted cats.
There both great cars,i like f-bodies alot and had one for 9 years,i just like the vette styling better and no rust..Also c5s look awesome slammed,i slammed mine 4" inchs..

My best was 2.1 with run flats,nowere near bogging for me,and thats leaving at idle,if i power brake,i get 2.3 or worse,spins like mad,we can only race at night on a bare track,and to much power brake will kick in the "torque managment",i think it was 1500 rpms with brake applied more than 25%,feels like when the traction control kicks in,i did bog that time due to torque managment,i also have 3:15s..
I haven't been with my zo6 wheels yet.

In actuallity it's a drivers race the only difference is the 01+ F-bodies and vettes are a little stronger from the factory than the earlier LS1 cars.
My 00 SS dynoed 304/325 stock and ran really hard with minimal mods.(12.59@112 with intake,Exhaust,Ported TB,FTRA,ET Streets)
I rarely if ever lost to a similarly modded C5
I now have a 04 C5 coupe that dynoed 317/337 stock
Stock for stock it launches better and would have pulled my SS in a race.
With intake and exjhaust it Dynos 335/353 and is really close to going into the 12's with a 2.1 60ft.(On nittos I think it will go 12.79)
Basicly if I saw a stock F-body racing a stock C5 I would keep my wallet in my back pocket from a betting stand point.(There only as fast as there drivers)
From a braking and handling stand point the vette is the clear winner.
From the bang for the buck stand point nothing beet a f-body from 98-02

The bang for the buck is probably debatable too,as it takes more to get a vette,but you get much more back when you sell also.The c5 is so easy to work on and the trannys are in the rear of the car.
And no one mentioned the c5 doesn't have egr,no throttle cables and is cleaner looking if you into that sort of thing.I love the HUD also..
