I've read through a number of threads on here about this stuff, have messed around with t/c off and on and have major issues with the stock tires on this car, so I have two questions if you guys wouldn't mind responding.

1.) If you have a 6-speed manual and are relatively good at launching, would you mind sharing your secret?

2.) My prior car to this is a s/c 97 Cobra Mustang that I have a set of ET Streets for -- would these mount up to my C6 axles and how weak is the stock rear-end on the C6? (do I need to beef anything up before going to the track and launching the car?)

Thanks very much for your input. I'm hoping this can be a very informative thread for those of us who are not quite as experienced. With my ET Streets in the Mustang, I also have a line-lock and would always do a 6-8 second burnout and just dump the clutch at 4k and pull ~1.7-1.8 60' times without any trouble...this car may need some learning on my part and I want to be sure I learn as much as possible so I don't break things when trying to launch the car.

Thanks a ton.

 

I have not run my 08 yet, but have had two other C6's, and two C5's I have run at the track. My methods are not going to give you the kind of results that someone like Ranger gets because I don't go out very often, and I don't want to fry my clutch. (BTW, I'm not saying Ranger fries his clutch - I'm saying that if I tried to do what he does, I probably would fry MY clutch). But I do have some suggestions.

First, I believe that the biggest thing that results in TM intrusion is "shocking" the drivetrain. That basically means that if you are on a sticky track, and/or with sticky tires, the clutch does not like to be dumped, it likes to be feathered.

As an amateur, one thing that helped me a lot is the way I stage. When both yellow lights light up, I bring the clutch out to the point where I can just start to feel it engage, but not enough to roll out of the staging lights. This keeps me from banging it too much when I do launch. I think this method also reduces the chance of axle-hop - which I virtually never get on my launches.

Again, keep in mind that I have turned 60' times in the 1.95 range on the factory runflats. I know that is not where the top drivers are - they are likely to get into the mid 1.8s with runflats. So I don't claim to be the best, but I do get good solid runs, and very consistent.

Good luck and let us know what works for you

 

heres a vid i made over the summer, i hope it helps. You dont want to be dropping the clutch with a racing slick on the stock axel. harden output shafts help alot for strength. the biggest probs on the C6 is wheel hop, softer non run flat tires help, kooni shocks help more and a coil over suspension completely eliminates it.

 

I recently went to the track with my 08. This is all good advice. If I shocked it off the line, it went into wheel hop. I launched on runflats at about 2K, and gave it as much gas as I could with out really breaking the tires too loose. This car will launch if you find the sweet spot. I ran a bunch of 1.9s, and hit one 1.86, which ended up being my best pass: 11.83 @119.94 MPH!

Good luck,

JB

Fess up...your sweet spot is Jenny P with a shot of Torco!

 

YEAA THE TORCO!!!! HEY MAN I HAVE TO ADMIT THATS ONE SWEET VETTE, GREAT RUNS HE HAD , 11.8 is PURTY DAMN WELL FOR ALL THE MINOR STUFF HE DID ON RUN FLAT TIRES

 

Thanks a ton for the feedback guys. I don't mind doing suspension mods to make the car hop less and do a better job of just squatting and hooking up -- is there a good suspension package out there that will help with this without totally destroying my bank account? Also is it worth just getting a tune while the car is stock to tune out the TM?

Thanks again, you guys are awesome.

 

Also is it worth just getting a tune while the car is stock to tune out the TM?

I know one guy (Glennhl) here who figured he dropped .2 seconds off his 1/4 mile time with the TM "Upshifts" disabled. I just bought a HP Tuner and shut off TM Upshifts myself...going to the track tomorrow to see if it will improve on my recent 12.65 time. Stay "tuned".

 

If you a really into drag racing, you can mod the suspension to get better launches, but with some practice, a sticky track and tires one can get out of the whole pretty good!

Without doing any mods, there is some HP on the table with a tune, as well as the TM.

 

Are you all power shifting or speed shifting? I need to know cause I'm going on Sat. and i might try Power shifting.

 

Is there a particular brand of coil over? And, are the Kooni shocks better than the Blisteins for eliminating wheel hop? There were a few negative views on the Blisteins regarding wheel hop. Thanks in advance.

 

this is an '06 z06 on runflats, but it's a pretty good vid showing the wheel reaction off the line and also the fact there was a huge headwind, so you can really hear the throttle modulation off the line I made. I held the revs about 3200 and just progressively lifted off the clutch and squeezed the gas pedal down, basically inverse relationship. It's probably WOT and zero clutch within 5 feet of leaving the stage box. 60ft was 1.84

I like the analogy of facing a busy intersection off a side street at a stop sign...you want to get across fast and use the throttle, but avoid lighting them up.

 

Listen to this guy - he's an outstanding driver!

You got that right....and after watching that vid, I now understand what Blu-By-U means!!!

 

 

11.448 @ 123.37 completely bone stock is impressive.

 

 

On F1 Supercar Run Flats I've found that on asphalt, bring the revs up to 2500 rpm, and sidestep the clutch, keeping the revs at 2500 for an instant. The second the car hooks, ease down the accelerator. Don't punch it. No one ever won a drag race by spinning the tires. And you can get sloppy and slip the clutch, but you'll smell it, and that's not good.

A good driver can snap off fast enough 1-2 and 3-4 speedshifts that powershifting doesn't offer much advantage. Practice the 2-3 shift. It's a biotch on the T-56.

 

LMAO You da man if you could make it for a minute

 

I dug up the two slips from that night. I actually cut a 1.821 on the 11.44 video above. I forgot I had the video from the second run, and this is a good example of what can happen if you get a bit too high on the rpms off launch (3600). I'm not sure how good the ls3 clutch will take a little slip, but I know the ls7 hates it. This was going to be a great run, the headwind had died down from earlier and the temp had cooled off. I cut a 1.815 60ft here and the clutch sticks to the floor as I'm reaching for second. pops a split second later and I make the shift. Not sure how much that cost me
