I was so upset after that run I left the track! This car has been fighting me for way to long an took the fun out of it. I was having constant problems with my 6 speed, when it recently trashed the throwout bearing I threw in the towel! I love this car though, that's why decided to stick with it and swap the trans. If my M6 worked properly I would have loved to stick with it, I just could not justify the money it would cost to run it how I want.

If I were you, I would put a even steeper gear in it instead of trying new tires. Once they are worn then get some mickys or nto5s. I would put a 4.33 in that thing, it will be much easier to keep the car in its power band out of the hole! It won't take as much RPM to launch the car and you already have to shift 4th so might as well make it worth it! I think you would see a solid 3 tenths easy with just a gear.

Holy cow, 3 tenths you think?

Yes I do, it's a heavy car with a small block. The factory really under geared this car as far as drag performance goes. When a car bogs the engine down at a 4k launch it's for one reason, not enough gear. That's why there is only that small window to get a good launch..these cars bog or spin! With the right gear a 4k launch should get this car moving hard off the line, the gear will compensate for the wieght and keep that motor in its sweet spot instead of pulling it down.

Only a little better 60' last night dropping my pressure to 22 pounds. But still no better than 12.4. And now I may have fried my clutch with only 4,000 miles. On my last two runs the motor revved freely in first and second after the clutch was all the way out. Although it did seem to be back to normal on the way home.

Some Improvement

Last Friday was promising. I am getting slightly better at launching with DRs and my ETs improved slightly even though my best run was not my best 60'. I ran a couple of 12.400s with one run dipping into the 12.3s.

My best so far is 12.378 @114.30. Even though this 60' was 1.983. My best 60' that night was 1.927. I know, still not good but my best 60' so far including my '11 SS. I am running my NT555Rs at 20 pounds. A couple of times I felt like I was getting a better feel for the clutch grab point while giving it gas.


As far as Mustangs go I am competitive or faster against almost all of the stock Coyote ones except for 2013+ GT500s. Last Friday I ran against my first Boss 302, a stock one. We were very close. He was running low 12.5s and one 12.4. He beat me though 2 out of three. I treed him and beat his ET to win easily the first time. But I made small mistakes on the next 2 runs. It was really exciting fender to fender racing just like my previous runs against a stock '11 GT500. Most of the time running against NA cars with a similar ET and a better 60' I can run down the other car at the end of the track. But the boss is different, If I did not have a lead by about half track, he would pull away. He had his track key turned on.

Those Bosses make big HP stock. The rumor is the 2015 5.0 Mustangs will have 500 hp by the end of the '15 model year. I wonder where they found all the extra HP? I may ned a Turbo.

That's a really solid pass man, your doing a good job of driving. That's strang you slip says 29 mph in the 1/8th! If you can get that 1.8 60ft that's a very low 12 sec pass right there!

Yes I was going to go to Atco on Tuesday, but it was closed. Hopefully Friday it will be open.

RT4T is going too. Camaros must represent! The place is full of Mustangs.

Thanks! There is still more in it with a tune and some better DRs. And better launches with practice.

Yea, I think Atco was having problems with the 1/8 mph.

Atco hotline says it's on. I look at the radar projections and i looks like rain will not move in until after 9. But double check the hotline before you go. 856-768-2167
Edit: On the way there they closed it.

Lots of Camaros at Atco Black Friday. Good track prep on a cold day. Last runs of the year for me. Got my best 60' so far, a 1.888. Not great, but happy to see some improvement. My last run was on topic with this thread, against a Boss 302. The 1LE represented and finished with a win. Thanks for the help.

I also squeezed out a new best:
