Just out of curiosity, what where the temps that day for those runs, and how much would your time be affected, if any, for about every 5 deg faren hotter?

It was in the mid to high 60s most of the day and got really close to 70. So it was definitely no huge advantage like if I was up north in 30 or 40 degree temps.

I haven't had enough of these cars to the track in different temps to get detailed data, but I would gestimate every 10 degrees F would add or remove .5 to 1 mph on a full run. This would also be affected by cool down procedures and if any ice was used or if they had our intake spacers or not.

NA cars don't see as drastic of a difference as Turbo cars with ambient. But I would say around 85 degrees or so these NA S4s would probably start to suffer more drastically.

I am basing this off my 15 years plus of racing NA Mustangs.

Thanks.

Thanks for the info. I ran consisten 14.0's on the quarter and was highly upset. I have normal tires and I had just finished driving 360 mi to get there when I did those passes. It was about 90 that day, and I still had my subs in the trunk (approx 70 lbs). I just wanted to know if that had a huge play. That or I just need to learn how to drive better.

The 90 degree temps probably cost you a mph or 2 over if it was 70f out. So without subs and better temps you would have ran some 13.9s or 13.8s no problem.

If you post up the slip info I can do better analyzing where the problem is (I can better determine if it is the nut behind the wheel or not

). Might have some tips for you as well. Knowing the trap speed, 60ft and half track speed and ET give me the data to dissect the run and have good feedback for you.

To better help. What was the gas you used?? What is your full mod list? What RPM were you shifting at?? What RPM were you launching at?? What technique??

R/T... .746
60'.... 2.074
330... 5.954
1/8... 9.107
MPH... 78.31
1000... 11.775
1/4... 14.037
MPH... 99.65

My full mods list is in the signature block. My engine was still pretty hot from the drive. I launched anywhere from 1k to 2.2k. I was being a little bitch because I didn't want to be stuck 360 mi away with a bad clutch. I have videos I can show you as well. I shifted at about 6500 rpm's. All the passes where about that.

Sway,

Don't feel bad that is about right for what you have. A chip is going to do nothing with stock Dp's but hurt the motor after a while.

My advice. Get some piggie Dp's throw away the EVMOS intake thing and have Jay set you straight on some helper mods. My car went 14.3 @ 98 stock 13.3 @ 107.3 With the JHM mods and Im a automatic

I'm waiting for the headers to come out. The intake sounds nice. I'm going to wait until I have a dyno available to see for myself. I'll have the stock intake on hand. I've read the thread on intakes. Don't think I'm not taking you're advice. I see you go through a lot to prove what works and doesn't work.
