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.

Good stuff. I've been looking at 2002 Camaros, maybe I'll have one next to my Terminator some day :D

Is there a big diff between the Z28 and the SS worth paying for? I hear all LS1s are the same.

My 05 expedition...probably somewhere around 9 minutes...it would do it faster than that, but I'd have to stop for gas somewhere along the way, and that would slow me down even more...

I was actually playing in manual shift mode today... it was loads of fun let me tell ya. I decided to waste a little extra gas shifting at the more speed optimal RPMs as I got 26.5 mpg at my fill-up yesterday! Pretty good for a car where most people say they get 22-23.

I bet the Altima'd do a bit better if you took a lot of the weight out of it... dang thing's a porker at 3.3k pounds. The real question in my mind is... will the VQ35HRTT (probable engine that the GT-R will use) swap be possible :evil:?

Me and a friend tuned it. It still needs alot of work at part throttle but it's nearly finished.

Power UNDER the curve is what it's all about. HP is just for bragging rights.

I purposefully bought the Z. The only major difference between the Z and SS is the hood, spoiler and price. Besides, the SS's were over produced since everyone knew they were no longer going to make the camaro and everyone wanted to order the "top of the line" car. IMHO, it's harder to find a good Z than an SS.

Not mine, my sister has a 1968 Z28 with a prototype keith black hemi 429 and custom tranny that she does low 9s with. I think she broke into the 8s once or twice. No turbos supers NOS ect...straight up engine.

She also tweaked my car, 96' Chrysler LHS that I can get mid 12s with. Automatic V6, and if Im cruisin I get about 26-28MPG (~65MPH). Tranny runs outa gears at 130-140 but engine is only pushing 3500RPM and redline at 6500. For a 3800lb car not bad.

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.

Although I only get 14.5's @ 96mph on my 1985 vette I have a top speed of 152.

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

im hoping my project will get high 12's
Its a 1990 TA with the LT1/4l60e swap
Mac headers/banks exhaust
Custom Tune
Emissions Delete
3000 Stall
Some weight reduction
Im pretty sure my estimated times on this car are down to earth since it is about 300 pounds less than a 95 z28 with the same motor and some mods

There are beefups for the 'vette IRS, I don't know how well they hold up though.
