Suggestion
In this case the parameters need to be altered in the ECU that adjust the air/fuel, advance of timing, etc.
Leading evidence: 'Adjust air/fuel, advance of timing, etc' (no explicit attributable resolution; this is a reported action or suggestion).

Do that a bunch of times then replace your clutch.

Drop the clutch at every light + replace IMSB with every new clutch?

Suggestion
If I set the line locks with the front brakes at about 50%, I can do long, slowly looping donuts the size of ANY parking lot.

Suggestion
Nail the brakes and give the wheel a flick, set the locks and nail the throttle, and you get an epic 180 that can be as tight or loose as you want based on how you set the locks.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

The problem is at least for my 3.4 with a LSD is that the wheels don't slip and it will take as much power as I give it - so it could take out like a bat out of hell but man, the clutch and drive-train wouldn't really like it.
Maybe Turbos are different, maybe GT3's or GT2's are different, but I just can't see this as a light to light kind of car - and if that is a persons goal there are other vehicles out there that do a much better job at it and that would be easier/cheaper to maintain.
IMO
For my C2, 3,000-3500 max seems to be a good number for AutoX starts etc. I read an old magazine article that said the C4 was a tougher car to launch but no real experience with it.
Speaking of reading, I read a post by Paul Guard talking about the factory LSD being for street use only. That the ceramic material on the friction plates wouldn't hold up for track use. But that guard could resurface them with a composite material and they would be good to go. How's that for a random piece of off topic information?
I have a 996 C2, 3.6L NA
My Evoms stage IV tune has a 5k launch. They also sent me a revision with 4500, which I have not changed yet.
The 5k is about as much as you need with a bunch of modifications to back it up.
If you don't have improved motor mounts, you will get some wheel hop.

Are you one of those arseholes who leave tire tracks in the country lanes?
. They spin the car around for kicks. The kind of person who should not be behind the wheel of a shopping cart, let alone a high speed car. I hope you are trying those stunts on the race tracks and not public road ways. Just saying.
NYouffitr
Thanks for the video. Didn't look like you had any wheel spin. How do you like the Evoms tune? I have intake, exhaust, X-pipe 200 cell cats. I'm on the fence about a tune for cost vs. benefit.
I've found wheel hop to be the limiting factor. Some surfaces are worse than others, and a lot of the places I launch from on autocross have gravel from everyone launching. 3-4k usually provides a healthy launch with just a bit of wheel slip modulating the clutch. It's fast, not too tough on the car, and keeps the car launching in a straight line.
The ProSolo guys that do dragstrip starts launch much higher I believe, and just accept the wheel hop and budget for more clutches and axles.
Depending on the surface, around 2500 with a little clutch slip or 3000 is best with my 300tw tires and open diff. On a good surface like a prepped strip can get away with more rpm 4500+ but wheel hop will be an issue. I've found an aggressive clutch slip to be faster on open-diff 996s but not all will withstand more than one or two without a lot of cool down time.
ssssoooo many different variables here.....tires/temp/road. 3000/3500 is a basic starting point. bear in mind these cars DO NOT have a manly clutch and IRS does not take kindly to drag racing [wheel hop] nor does any of the drivetrain . po believes reving the snot outta every gear and hope you get to the turn first..............it has not worked for 20 or so years now. now their PDK is quite a street light sleeper all it needs is a motor with 150 + ft lb torque. bottom line is DO NOT throw down with corvettes at street light
Are you one of those arseholes who constantly makes wild and baseless accusations, spewing vitriol and casting aspersions based more often than not on your complete misunderstanding of the topic at hand? The kind of person who randomly adds "the" to terms to create linguistic tragedies like "the racetracks" in such a way that it becomes almost impossible to NOT imagine you as a bellicose 2-year-old hell bent and determined to stick the square block in the round hole? The kind of person who infuses the atmosphere of this thread and so many others with your unique musk of steamy, malodorous, completely unfounded acrimony?
Just saying.
Whoops... don't get your knickers in a twist. Are those medicines you mention in your posting. Vitrol? aspersions? Bellicose? Malordorous. Acrimony? Please type in layman terms so I can understand what you are trying to say to me.
Sam and Todd @ Evolution motorsports are very customer oriented.
They go over with you, your current setup and anticipated modifications.
Then, what you are looking for the application of your car.
I personally struggled with shelling out $1k for something you can't touch or even see.
Certain modifications actually rob your 3.6 of low end torque. In this case the parameters need to be altered in the ECU that adjust the air/fuel, advance of timing, etc.
Before you go any further with your modifications, take a moment to figure out where you want to be when you are done.
Make sure everything you do today will work with what you do next year.
Good luck, and have fun personalizing your car.
LOL @ Hurdi.
Yes, I am one of those ********. Even my garage floor is covered in tire marks. Can't help it, AMG makes 2x the peak torque of your 996 at 2k RPM

Personally no as the 996 can't easily make tire tracks, but I am one of the ******** that will take advantage of the lack of traffic on lonely out of the way country roads.
Looking to bribe a friend with a car that can leave tracks sometime and go through a set of rear tires. Then yes, I will be that ******* that does what you said.
You would love my Corvette, Hurdi. If I set the line locks with the front brakes at about 50%, I can do long, slowly looping donuts the size of ANY parking lot. Line locks are also epic for a rapid unplanned change in direction of travel once you get some basic skills with the line lock switch. Nail the brakes and give the wheel a flick, set the locks and nail the throttle, and you get an epic 180 that can be as tight or loose as you want based on how you set the locks.
Driving like a hooligan can be incredibly fun, but I keep my hooliganism confined to places where the only person I can kill is me...
