this thread needed resurection, must get all the facts of new edge vs ls1 out on a regular basis.


antonio, he just said it was actually an LT1 (i guess a 97 or earlier, not an 01 afterall)

I wish i could find a stock LT1 or LS1 to race.. the only LS1s i see at the track are modded 'vettes, no camaros/trans ams..

 

doesn't matter too much, those vettes are running te same times an F-body would run with the given mods.... on average there is really no difference at all between a C5 corvettes track times and a LS1 trans-am's/camaro's

 

Odd that. Seems like the better drag coefficient and weight should make at least some difference.

 

yeah.. they should be a bit faster since they are a few hundred lbs less according to the internets.

what i meant was the only LS1 i have been to the track with was a modded 'vette (heads/cam/exhaust) I think it ran a mid 11. seemed like a nice guy, he talked to me a bit in the staging lanes, it was my first time out.

 

I've seen a stock C5 auto do a 13.8 @ 103. 2.0 60'.

I saw a stock C5 Z06 out there. 12.6 ET, not sure about trap or 60' on him.

Sadly our track pretty much sucks for street cars. It's 75-80% built up dragsters out there and that's it. :/

 

You got that backwards....the more fast cars out there the better the track prep is. 99% of the time anyway.

 

I agree with this too, but oddly enough both cars run the exact same times usually... low-mid 13's seem to be the norm from both stock

I've been stumped as to why for awhile... the only two factors I can think of is that the curb weights are off from the factory (while the vette doesn't have any backseats and is lighter from a cabin standpoint it also has IRS which weighs more than a SRA setup... so it COULD equal out in all reality... I don't know for sure though, just a shot in the dark

the other thing is based on the IRS as well.... the F-bodies may be easier to launch at the drag strip with the SRA making the hole shot easier to accomplish evening out the aero/weight disadvantage... making the vetter shine up top a bit better and the F0body shine from a stop a bit better... thus equaling this out as well

but this is just two theories I've thought of as to why, nothing to really take to heart

also... all in all... I really don't think the aerodynamic advantage is THAT much more.... better? yes but not enough to show a huge pull IMO

 

Makes sense to me. I'm guessing that maybe the aero advantage isn't as big of a deal on a 1/4 mile strip. As things move over 130+ it probably becomes more of an issue.

I've heard before that corvettes aren't "set up for drag racing" and are harder to launch.

 

I was thinking the exact same thing. On paper, the C5 should be much faster, but it isn't. I wonder if the Vettes torque tube thing has any negative effects as well.

 

Nailed it.. this just came up on another forum.

C5 Curb 3230lbs
My car 3440lbs

IRS vs SRA takes some of the weight advantage away (testing done back to back always showed the SRA car making a bit more rwhp) but ultimately the C5 still holds the best times. The aero advantage of the C5 doesn't really help until 120+ (seen it first hand... what is a side by side run to the 100 mark becomes defeat as speeds rise).. It's also said a stock C5 can reach 177mph while an F-body will barely crest the 170mph mark (limiter removed). Ultimately assuming everything is equal (60ft and driver) the C5 should end up 1 ~ 2 tenths quicker and 1 ~ 2 mph faster.

C5 Stats... Published stats for the C5 were .29 and 20.7 frontal with a 6.003 Cda.

Camaro stats are a guess at best... GM didn't tunnel test the LS1 designed 4th gen... all we know is that an LT1 4th gen (with it's sqaure headlights and hood vents) is .34 with a 22ft frontal and 7.48 Cda. It's been speculated that the LS1 is .33 with a 22ft frontal and 7.26 Cda (not that it matters either way).

The only way the f-body comes close is if you race the C5 at night and he is forced to pop his headlights up otherwise the advantage is pretty large.

One that that I always find interesting when this comes up...
F-body .34 x 22ft = 7.48
C6 Z06 .34 x 21.9ft = 7.446

I can never tell if our cars were really **** aerodynamically (always overshadowed by the C5) or if there weren't really that bad. Ultimate I think there is more to aeros than just these basic numbers and I need to go back to mowing lawns instead of trying to make sense of it.
