Hello all, im sure this has been beaten to death somewhere here:fight:. Im heading to the Track for the first time in my M6 srt8. Stock tires. I realize im not going to launch without spin, but what are peoples best experiences and RPM launches to best prevent it? What estimated times should I expect to achieve? Only been driving a manual for a month now, so still adjusting. Thanks

What has worked best for me is rear tire pressure down to 26-27 pounds (fronts up to 40), avoid the water box if you can and keep the RPM less then 1800 (I am finding 12-1400ish works well for me) and moderate throttle advancement at launch (back off if you get a lot of axle hop. This is presuming Goodyear F1's. Getting the car to hook up is the hardest part. I try to start my shift to the next gear about 200-300RPM before redline. You should be able to be in the high 12's when sorted out. If your tires are new that might be helpful. I have always had at least 8,000 miles plus before I could get to the track. Play around with this stuff. On my old 6.1 6 speed my car was happier at 21 pounds pressure with the rear tires. If you are not hooking at all consider the water box and a brief burn out.

The reality for me is 2.2x 60 foot times with the goodyears in either my 392 or the old 6.1, rarely lower. My best ET has been 12.901 but I am often 13-13.1x. My trap is 109.5-110.5mph very consistently. If you launch at a higher RPM I think you can do better but you start to risk parts. There certainly are people on here who do better then me with the six speed and of course the autos are have it down. I think the car can be in the 12.6 range stock with the goodyears, good track prep and a good driver.

Have a blast

And turn on sport mode and experiment with traction control fully off vs partial. On the 392 I think I have more success with TC only partially disabled vs fully off on the 6.1

Don't do a burn out if you're on street tires. The street rubber compound is not the same as a drag tire compound, Where a drag tire will get sticky when hot, a street tire will lose grip when too hot. Just spin the tires briefly to clean them off and make your pass. You want to find the sweet spot between bogging and spinning. Ideally you will have a little spin and then hook. If you launch at too low a rpm to completely avoid spinning, the engine will bog. Each car and each driver are a little different. Practice, practice , practice.

Practice makes perfect. Don't be afraid to make mistakes, especially at first.

Keep notes on launch techniques and other variables, so you can learn what works and what doesn't.

Find other drivers at your local track and talk to them. Especially those driving manual trans muscle cars. What you can learn from them is invaluable.

Just have fun, make as many runs as you can each trip, and enjoy the process of learning a new skill.

I'll just add this. Don't dump the clutch. Bring it up a little so it's at the point of engagement. And try to learn how to slip the clutch when changing gears. Otherwise you'll be spinning the tires. It's all about practice practice practice and finding the sweet spots. Lower rpm range at launch works for me as well.

I think this is a good place to ask. What is dialing in? Like what is the number I see on windows for? And the letters. Sometimes I see letters and I don't understand it. Sorry if it's a noob question I've never drag raced before but I watch it a lot and love going down to the drag strip.

Dialing in is part of bracket racing. Bracket racing is a way to handicap the cars so that fast and slow cars can compete together. Usually you get a couple of time trial passes to see how your car is performing on a given day. When the elimination rounds begin, each driver estimates their elapsed time and writes it on the window of their car. That's called dialing in. The slower car gets a head start by the difference in the dial in times. For example, a 12 second car will get a 2 second head start over a 10 second car. If you go faster than the dial in you are disqualified. You want to go as close to your dial in as possible without going faster. Reaction time, the time it takes to react to the green light on the tree, also comes into play. Theoretically, if both drivers have the exact same reaction time and run right on their dial in they will reach the finish line at the same time. It makes it a drivers' race and is all about consistency. The lettering on the cars refers to the class they run in.
