Very nice, overall, but your et is a bit high for that mph.
I know, i have traction/launch issues.

Thats typical with bad 60' times due to poor launching, traction issues, lots of top end power with no bottom end torque, centrifugal induction lag, big cams, running on DOT rubber, etc. With a modded LS1 Z28 I'd say its a launching/traction fight on street tires and most likely has a lumpy high RPM cam, etc.
A lumpy cam is a LS1s best friend, but the problem is you are pinched between two constraints. If you launch at a low RPM you bog the engine on that big cam, but if you launch high RPM, you break loose, so finding a comprimise can be challenging.
i have a cam-n-more.
EDIT> There's a mod list and dyno graph floating around here in ATOT somewhere.
My car had a great torque curve but my gearing and suspension setup is less than optimal. My cam also pulls VERY hard in the higher RPM band.

they are not. 11.8 was at 118, i ran a 12.5 or so on the 121mph pass. BAD wheelspin but i stayed in it.

running 100% n/a, cammed, etc. STOCK heads, they've never been off the car or touched. No giggle here.

While that's certainly possible, what could possibly be your point? That his 121 MPH run was achieved on a 12.1 sec. run, perhaps? That his 11.8 sec run was accompanied by a 119 MPH showing?
see above.
I know my et's have ALOT of room for improvement but the car as it sits now just can't launch. Besides, I'm still on a stock 10 bolt with a high stall converter so it's all borrowed time. Either the trans or rear will let go at some point.
EDIT #2> You usually get your lowest MPH on your best ET because your run is more "efficient" at comering the given distance. When you spin/launch poorly, your MPH usually goes up unless you REALLY tank the run.

Not sure if it's in D or M.

Lovin' those curves! :thumbsup:

Good stuff. I've been looking at 2002 Camaros, maybe I'll have one next to my Terminator some day
Is there a big diff between the Z28 and the SS worth paying for? I hear all LS1s are the same.

Not buying it, buddy. Not on just a tweak. Either you got something else in there or you're lying.

Im not sure that info is correct, it ran 1/4mi at low 15s stock. Im not lying. The CD seems wrong too, I thought it was supposed to be like .32. But anywho...I duno what qualifies for a tweak or what else to call it, but Ill admit alot of stuff was done. Im no expert so I cant say for sure what all exactly, engine and transmission work as well as intake and exahuast. Pretty much everything. I managed to get 12.58s on the 1/4 after all was said and done.

Vettes handle well though. Plus on the newer ones, the IRS doesn't take to kindly to 6k clutch dumps.

The Cobra IRS can, with a little help, so I assume the Vette can be beefed up the same way:

Ever seen a 2003 Cobra on slicks do wheel stands on the IRS, crack off some 9s and 10s, change the tires, then drive home? It's beautiful :Q
