I posted this in the Drag section to see if I can get help there also.... but so far I'm up against a wall...
I have a question...
Re: Torque management...(Remember I DON'T care about how much HP its making)
If a shop puts the car on a dyno.. Can they dyno it from a stop, & just floor the gas and let it accelerate to say app 120 mph then let off... I don't care what the dyno reads, but maybe if they have a computer hooked up to the car they can see if its pulling timing out at the "Hit" of the throttle?
I've never seen a dyno run done that way, they usually start easy and nail it at app 3000 run it and let it coast down...
I'm interested to see what the cars computer is doing UNDER FULL THROTTLE during ACCERATION... maybe it would be better to hook a laptop to the car and run it at the track...
All I'm looking for is CONSISTANCY.... I have been told to "Roll Into the Throttle" Have any of you guys tried that running on a Pro Tree...
At this point if ANYONE cant get my car to be consistent, I'm gonna throw in the towel for the CC points series, & just run it whenever I need a "RACE FIX" I refuse to "TRY" and run if the car can't be competitive..
Originally I had planned to make it into an 11.5 car for next yr. but if its going to run 11.52 then 11.70 on the next run I'll become a "Waxer" or help Edgar taking photos... I refuse to put 3,4,5 thousand into a car, and be told you have to Roll Into the Gas"
Dammit I gotta stomp it to cut any kind of light on a .500 Pro Tree...
Thanks to any & all who can help in anyway..
Jeanne ran the car this past weekend at the Division 1 finals...here is what happened..
Example Jeanne ran 12.52 then 12.54 ....two days later (due to rain) our weather stations BOTH predicted 12.60 and 12.67 We dialed 12.69 and based on the 1000' it would have run 12.80 (it was a little slower because she saw she wasn't going to catch the other car so she dumped it) it would have been 12.80 or 12.81 @ 109
That is not acceptable.. EVERYTHING was the same. launch RPM engine, trans oil temp, tire pressure, same lane, the 60' was only .05 slower but the run was 3 FULL TENTHS SLOWER

Sorry, I could only find a Mustang and Firebird video quickly.
If you can find a shop with a Mustang brand Dyno, it does 1/8 and 1/4 mile simulations. There is one here on LI that I know of, maybe you can find one near you. I dont think there is a Dynojet that does 1/4 sims, but I could be wrong.

you buy a world class sports car IE: road car and then get upset with it because it's not a top fuel funny car?
Have you ever Drag Raced in "Serious Compitition"... not just having fun...I take it serious, you sound more like a spectator who had taken your Vette down the track just for fun...
I think your confused... I never mentioned I want it FASTER...I want it to be "CONSISTENT" is that too much to ask.. If I wanted to run FAST.. I'd have kept a D/A 290 ci small block that ran low 8's
I spent a lot of $ on this car, & in my original post I think I said I'm NOT looking for more HP or better ET .. just "Consistency" Is that too much to ask of a

I wasn't going to say anything but I too don't fully understand why some people think holding the gas down for a dozen seconds or so is that exciting of a motoring event... I guess it is not quite as pointless as driving around in circles (Nascar) but coming from a road racing background I was actually quite bored my first time at the 1/4Mi track and haven't been back since. I'm hoping it will be marginally more interesting with 600rwhp but more likely than not I'll just get booted... Oh well

Yup after reading some of your posts.. you having a 600 HP car is like Barny Fife having a 44 Magnum... Remember no matter how big of a gun you have if you miss... well "A loud Noise Never Hurt Anyone" you better hit what your aiming at..
Sooooo you have 600 HP I can get 1/2 a dozen 450 HP car to beat yous in the 1/4. Like you I can't understand why a person would get all the "Bling" that you got for your car... does it help you pick up chicks
Or do you plan on breaking that 200 mph on the Garden State Parkway..
At least I can say I've won some $$ with my race cars...I don't give a Squat how much HP or Torque my car has... as long as I can win...
If you want I'll have a plaque made up for you 600 HP to paste on the side of your car.. and maybe you'll get even more "Chicks"
Good luck with that 200 mph run & keep us informed... add a little No2 and you can claim 750 HP

Bling? I have a stock exterior, stock interior car with zero cosmetic modifications of any sort. I put a blower on it because I got bored of having 395whp since I drive this thing every day...
You've won money with your race cars? Good for you. I've won trophies with all of mine, from the first vehicle I have ever owned down to this one, which I used to place 1st in my class at the Corvettes of Carlisle autocross and 2rd at the Winged Warrior 4 Autox/Drag competition. I don't need to race for money, my job provides me with enough of that
Can you get a 450hp car to beat mine in the 1/4 mile? Absolutely. This is a street car, not a 1/4 mile car; I run street tires, not drag radials and my gearing is stock.
Would I have as much fun daily driving said 450hp car on the street? No. And that's why I ddn't build a drag car, I simply put a blower on my street car.
Different strokes for different folk, I'm sorry if my posts somehow got your panties in a bunch
Oh yeah, I'm married BTW... No picking up chicks for me But thanks anyways.
Look, I'm not sure how close you want all your runs to be. 99% of mine are within .1 of each other on any given track day. From event to event, the ETs may vary by .2, but I have stayed within 11.3-11.5 for the last year, on street tires no less. It looked like you wanted to be within hundreths or even thousands of each run, I have cut the following times in consecutive runs: 11.37/11.37/11.38/11.41, but maybe that is too much varience for what you plan on doing. You mention being able to slam the throttle at the tree, well, the plan for you may be to look into a cable operated throttle body as opposed to the electronic set up we have. That may assist with your stabbing issue.It took some time (and I'm still learning 2 years into ownership) to get this car figured out after having a blown/h/c TA I drag raced for years, in bracket and heads up competition. Give it some more time, I'm sure you'll gain more consistancy as you figure the car out.

Honestly, I think that is close to what he's looking for.

If it could be turned off entirely then we'd be seeing far more of these highly modified C6s cutting 1.4 and 1.5 sixty foots instead of the 1.6s and 1.7s I see so many 450-550rwhp cars cutting even though they're dead hooking (little to no wheelspin).
C5s launch much better than C6s...and it just so happens that the torque management in C5s is more easily removed/remedied and whatever is left behind is also far less intrusive/invasive.

I"m no tuning expert, but we turned it off 100% on my 05 GTO (twin turbos). Dunno if the C6 computer is different, but there are several ways to get around it I believe.

What were your sixty foots after that?
The GTO PCMs are somewhat different though the LS2 cars do share a lot with the C6s.

Well really the only way to tell if it's all been deleted/removed or not is with before and after launches on a heated sticky tire at the drag strip, otherwise it's all kind of questionable and assumption.
The computer screen may say that it's been turned off but there are often so many more hidden and inaccessible tables still in there that there could be other areas left untouched to slow the car down.

Cool your motor a little John.
First thing is: " it would have run 12.80" and that's not an actual number. You want real numbers to work with, but you can't learn anything real by guessing what "it would have been". Ya gotta stay on it till the end.
Second thing is: the weather station's "predictability" varied by .07. That should have told you not to trust them so closely.
Third thing is: you prudently dialed 12.69 and then lost .05 on the launch which equates to .10 at the finish, so effectively it ran 12.79.
Fourth thing is: if it ran 12.79 and you "guessed" it ran 12.80, what more do you expect in the way of consistancy? The weather station said 12.67 and the launch cost you .10, it's still only a .02 difference, not 3 tenths.
The first time I ran my new one the times ranged from 12.65 to 12.89. It took some seat time to learn how the car reacted and for me to adjust. When I met you at E-town, my 4 runs were 12.21, 12.26, 12.25, and 12.26. The first run was before the temps went up. I got back to Phoenix and 100 degrees and ran 12.35s +- .02.

this is a rough one but it's not hopeless.
