Drag race advice for first time with 2011 GT

Well it looks like tomorrow night im FINALLY going to get to test my car at the track and get some baseline runs.
I was wondering what you guys are shifting at for optimum power? Car has stock 3.31's, Bama tune, Steeda Cold air, and axlebacks. I figured someone could give me some good advise.

First things first: what kind of tires are you running? This will affect your launch RPM.

Secondly, do you have any suspension or performance modifications/after market bolt-on's?

This will help someone supply good answers for you.

Launch around 2800 RPMS your first go and run it up to 6900 rpms.

I have done my best (with my mods) side stepping the clutch at 3200 rpms and running it up to around 7100 rpms.

11.9x at 116.xx mph with 1.71 60 ft.

Most of my runs are not shifted perfect or the traction was not perfect so 12.2x range is the normal range for me. I'm sure great drivers could stay in the 11's with my car.

Will his tires hook at 2800 RPM on launch? If he's running factory Pirellis, he'll likely have a little spin at that range. Might cost him in the 60ft. It's not a bad launching point, but he might fare better around 2K, if his tires are factory.

I realize I'm running a V6, so apples to oranges, but with my 3:55's, I couldn't get my 245 Pirellis (GT/CS 19" take-off's) to hook solidly at anything more than 1,500K RPM, and that's with maybe 60-100 HP less at the rear wheels than a GT.

Well...while I just side step the clutch (with what I have) I would not recommend you side stepping the clutch. Just let off the clutch while adding "feathered" gas through first gear and see what happens when you throw it in to 2nd at 6900.

Depending on the track and how much of a burn out you do will determine how well you hold in 2nd gear.

So about 6900 is good eh. Thanks thats what I needed to know. Oh and we cant burn out in the water box at least with street tires. I used to get past it and spin them real quick just to clean them off, but ive heard that's unnecessary really. Although I probably will anyway.

Many here have advised against it as well.

If you get a chance and have a secluded street or county road somewhere that you can be safe and away from other traffic, you might try practicing a few launches, just to get a good feel for what might work and what might not.

OH!! And drop your rear tire pressure down to about 25-28 psi...I'm guessing you drive around at 35-38.

Don't go through the water box

Don't do a burnout- just spin the tires to knock the crap off of them. A big smoky burnout on street tires just makes them greasy

Don't drop your pressure too low- it's a street tire, not a drag tire, maybe 28-30lbs

Launch either off idle or from ~2200rpm. You need a little wheelspin but not too much. If you can get the 60' to ~2.0sec, give yourself a pat on the back. Start your shift at 6.7k or so, depending on your gearing.

Make sure traction control is off

Be aware of the "groove" and stay in it. I made the mistake of ignoring it my first time to the drag strip, and my tires got "slimed" (melted rubber from the other cars coating my tires) and then I had zero traction. I did do the little wheel spin thing before the starting line, but I think I was putting more crud onto my tires than I was taking off.

If you can get a decent launch, the rest is relatively easy and fun. If you start getting crazy wheelspin, it gets very frustrating and completely spoils the fun.

If you're going to Gateway good luck going around the water box. With this heat most of the 5.0's are running 12.8-13.1 when they are around 2.0 60's.

13.6's are common with the guys who can't get traction.

I have similar mods and the same gearing as you in my m6 14 GT and last Friday was my first time to the track. I was launching at around 2000 rpm feathering the clutch off the line and had no traction issues. 2.2 sec 60ft. wasn't good but t still ran a 12.9 @ 112 so I was happy.

And don't do a huge burn out on street tires the guy beside me on my first run did this the dumped the clutch @ 4000+ rpm and almost hit the wall. Then repeated the whole process to a t on his 2nd run and the outcome was the same.

But just have fun and follow track etiquette.

Thanks for the opinions guys. I used to race before my second son was born. Ive had a couple cars I used to drag, I just wasn't where to shift at without dropping power and getting out of the band.
