The OP's C6 driver and the one the other poster beat in the C5Z suck at driving. My C6 bone stock pulled a few lenghts on a bone stock GT500 from 50-140MPH. These C6s are no joke, but , unfortunately, some of the drivers are. Realistically, a H/C setup and good tune and intake, and the C5 has a great chance. The C5Z and the C6 is a pretty even match stock(drivers being equal), but after 120-140, the C6 will bust it a new one.

 

Well Evil, your not driving a joke, that's for sure. The new motors are simlpy bad AzZ.

im going to have to disagree with you... my old t/a had a lid, and full exhaust and my own ls1 edit tuning which was basically just getting ltft's to 0. that car ran 12.98 at 111.9 with a craptastic 2.3 60ft time. now, the that is a heavy trans am(full weight) and i weigh about 270.

figure that kinda power in a vette(solid 200lbs lighter with lighter driver)

C6's are quick, no doubt... but they arent unbeatable.

like i said earlier. it would take between 350 and 375rwhp to beat one that is STOCK.

c5z? should win every time.


and yes, i hate the c6. mainly because im going to have to drop 8k on a forged short block and Ysi setup.

 

I raced him today... that was the outcome.... later.

 

that was a fbody though. i am talking about a corvette C5 vs a corvette C6... it should take 350rwhp in a VETTE, not fbod, to beat a stock C6.

 

Keep in mind guys i never said he was the best driver. Ive been with him in some of his previous imports and he could drive the **** out of those cars but ive never been in his vette when he was just killing it so i dont know where he shifts or anything. From a slow roll and a 50 kick i barely pull him in the TA, talk about him being upset!

 

Well then he wouldn't be a stock C6 anymore and the rules will have then been changed...I was merely talking about what it might take for an LS1 C5 manual to beat a stock LS2 C6 as per the original poster.
If the C6 shows up with say, a Vararam, DRs and some tuning it would likely then take a C5 manual with a Vararam, long tubes/off road X pipe, 4.10s, DRs/slicks, clutch and underdrive pulley to beat him, assuming equally skilled drivers.

 

You went 8.52 at the same track, same day? Driver aside, not all tracks are created equal, in addition to the weather conditions at the tracks. Hard to compare times from different tracks without knowing everything.

 

nope not at the same track same day as the other guys.....BUT the same day i run that time there was a stock a4 c6 that only went 8.77....im not downing the ls2.....i love em and want a ls2 stroker in my car but im just not impressed with them stock

 

it's the drivers, not the car or engine......

 

This is just my opinion cause i have never owned a auto car but it seems kind of hard to mess up with an auto.......and it wasnt spinning.......just my opinion

 

a stock automatic C6 has torque management embedded into programming, it'll kill et's if the driver doesn't know how to deal with it(i.e. if they stomp the gas from a dead stop and hook well, TM kicks their ***), the C6 also has TC which, if left on, can cut out wheel spin, but also hurts et's badly. The A6 also has D and S modes as well as a paddle shift option, and D is not as performance oriented as S or S w/ paddles, so there are tons of varibles on the table. I can see poor times from a stock C6 owner who isn't used to TM, leaves TC on and uses D to make a pass at the track. Hence, my statement, it's the driver , not the car.
BTW, FWIW: if GM says a car they make will do 12.5's in the 1/4, rest assured that it can do a bit better with a decent driver. GM don't want the same stigma that Mazda and Ford has had in the past.Is much better to underestimate than bull **** your buyers.

 

That explains a lot.....just assumed that everyone turned the tc off......tc SUCKS on all gm cars i think.....my camaro and the zo6's tc does the same thing. It just dies off the line.

 

exactly 99 frc lg lt's, intake, ported tb ti catback, tune, 3.90's took a c6 with intake and catback no tune by 1.5-2 lengths 0-120

 

I pulled one pretty bad with my old 3.42 gears.....I hate to see with my new gears what would happen.

 

Evil, you are correct. The TM will kill the ET. My 2007 Silverado with the Alu 6.0 has TM, it was so slow I couldn't figure what was up. Took a tuner friend for a ride with real time EFI hooked up. It was pulling timing from 24 down to a -16 (yes, negative 16). We turned TM off and it was like 50-75 Hp feel. No bog anymore, rpm stays up now and the motor just screams.

I wouldn't either judging by the times I've seen when I ran in Cali....my times including. Certainly driver is part of it, I'm still learning to drive my car after 100+ passes. However, the majority of the times I went racing was with temps in the 90+ range, DA's from 3-5000k, etc. Add in bad driver and times just suck. My car gained 4 mph in the 1/8th after having it tuned though, reducing TM was the key. Some folks get good times with them, usually in good weather and decent tracks.
