I'm with this guy. Even some of you guys' estimates of 3 or more seconds seems outlandish to me. 1 or 2 seconds at most, and probably not even 1 second. A full second is quite a bit of time, and the only real difference here is what, 200ish lbs? That's not going to give an entire SECOND to the C5. I could see it being true perhaps if stock C5s consistently ran 1/4 times at least .75 seconds or more faster than stock F-bodies but that is just not the case. Going from 105ish to 125 doesn't take that much longer so just imagine going just a bit farther than the 1/4 trap. No way more than 2 seconds AT MOST would separate the two.

In 2001 I bought a brand new Ws6 and my dad bought a new Z51 Vette. Both 6-speeds. When we lined them up I had around 8k miles he had around 5k miles, both bone stock. It was a real close race to 80-90, above that the faster we went the harder he pulled. I'd say to 125 it was only a 2-3 second difference. Thats bone stock, same year, roughly same miles, same gears, tranny and similar driving skill... apples to apples. A couple simple bolt-ons later and my car was just as fast in not faster than his to 130-140ish, above that he'd still pull.

i think what we've learned from this entire thread is to watch out for 95 Cobras wee doggy the new Z06 can do 0-130 almost three times before the 95 Cobra can do it once...hahahaha

I'm gonna say a difference of about 1-2 seconds. 3 seconds is a hell of a distance when going 100+ mph. I would lean toward the 1 second side of my guesstimate.

That sounds about right to me too, with my car stock I can run 13.4 at 107 fairly consistently. It’s an 02 M6 TA.

They're on crack. It's only about a second difference.

My question was about the LS1 Cars!

A4 C5 with 3.15 axle vs. A4 F-Body with 3.23 axle

A4 C5 with 2.73 axle vs. A4 F-Body with 2.73 axle

M6 C5 with 3.42 axle vs. M6 F-Body with 3.42 axle

Funny too that the german Corvetteowners think that an LS1 F-Body needs 6.9 sec to 62mph

Those people are on drugs. Tell them to seak help, like rehab. There is nowhere near a 7 second difference to 125mph between the LS1 C5 and the LS1 F-body, trans type for trans type.

And nearly 7 seconds to 62mph??? Now THAT is funny. Maybe on ice.

I will show this people this thread and then we see what happend.
One test in a german magazin stoped an Z28 with only 6.9 sec to 62mph and the people trust them..............

Do the fbodies in German have their nuts pulled off before they are sold to the public???? I don't know what they do to the engines over there, but over here iln the states, the fbodies make pretty much the same horsepower as a standard c5 Corvette. They advertise them differently, but there is no truth to GM's "official" hp levels on the LS1 fbods.

100% correct.

id say 1 second at most is reasonable

a vette has independent suspension, the fbody has solid, you loose more through the vetts setup. I'm not saying that makes the fbody faster. but being the vette has the weight advantage, wouldn't having a solid axle be the fbody's advantage? I drove a A4 c5 once, it was fast don't get me wrong but i sure am impressed with the performance of my WS6. I'd say it'd be very close, i'm not giving any time quotes

The EU- LS1 Modells from the Z28 are only rated at 288 PS and 434 Nm. The only difference is the single exhaust i think.
