Yeah I was thinking that as well. A combination of old used slicks, too short of slicks, and too much tire pressure in the slicks. Either way they definitely hooked much better than street tires.
I think my burnouts were likely all too short, and probably not launching hard enough. The highest I launched at was 3500rpm off the neutral rev limiter.
I'm uploading more of my race videos as I'm typing this, so if you guys have time please watch them and let me know what you think.
This was my first time ever on a real drag slick. I went out on the McReary dirt track tires, and American Racer asphalt racing slicks before.

Honestly when I was having issues at the line, I found the problem to be mostly in the shocks.

My shocks are oem with 21k miles. They definitely aren't meant for drag racing, but they should be in decent shape for what they are

Your burnout is fine, your staging is inconsistent and your spinning like crazy... anything else you want to hear?

Possible fixes would help. Constructive criticism welcomed. I've only raced at the track maybe a dozen times in my life, this was my first time on a real drag slick. In my SRT @ the track I cut consistent 2.0 60' times on 225/50/17 street tires, so I know 1.9x 60' on slicks isn't where it should be.
I would bet the spinning was caused by 20psi in the slicks. I was launching at 3500rpm at the most. Or possibly old used slicks, or maybe even the brand new paving of the track? Maybe a combo of all of those.
What do you mean by staging inconsistent? I try to stage as shallow as possible. Or do you mean trying to stage in the groove?

The inconsistency in the stage is how you are bumping the lights. This is a common problem with a manual transmission. Its just something you will have to work on. Every bit you bump in is a trade off of ET/reaction time. So if you bump in deep you will get a faster light but slower ET.
The 20psi definitely could be a part of the spinning problem. Street shocks and drag shocks work differently. Can the street shocks work, yes. Will a set of drag shocks drastically improve it, YES. For my car, I can not launch above 3400rpm at Sacramento Raceway as the track will not handle it. You can try bringing down the RPM and see if that helps out. Old slicks can be a problem. Also with how heavy the newer cars are, I recommend running a tube in the tires or get away from all that and just put drag radials on the car.

Yeah, I try to stage as shallow as possible, like you said, with a manual car it's a little bit of a pain.
If Lakewood makes some 50/50's for my car and it still uses a traditional shock in the rear they would be worth the purchase. I have them on my 93, & they work fine even on the street.
I suppose the best thing to try would be remember my good tire psi gauge & drop the pressure. If that doesn't do anything then I'll need some new slicks. I like slicks because they absorb a lot of the shock from clutch dumps vs. Drag radials, so I'll be sticking with slicks for sure.
New 28" slicks will likely be all it takes to get to the 11's. Less fuel in the tank wouldn't hurt either.

Actually drag radials love being shocked compared to slicks. The harder you shock them the happier they are.

Yes, but the shock is transferred more to the drivetrain with drag radials than slicks. Slicks absorb a lot of the shock rather than transfer it. This is how many people run 10's on stock axles on SRT-4's. Drag radials start breaking axles in the low 12's on SRT's, I would imagine the same thing applies to Mustangs.

I love mine. 22-30mpg on gas 12-26mpg on e85, goes 12's on true street tires. Not bad for a Neon. Bought new, now 72k miles zero problems. Trapped 113-114@18psi. Still have to bring it out now that I have it tuned, & 25psi. Should run low 12's without trying hard @ 118+ or high 11's with some good 60' times. All on stock turbo. I still have a stage 3 turbo I need to install to yield mid/low 11's, but will need a beefy clutch to handle that much boost.
One day I would like to take all three cars out and run them all on the same day.

Thats ironic, cause I have seen no issues with x275 cars running drag radials on stock 8.8 and driveshaft...
I ran drag radials (hoosiers and MT) and had no issues in my drivetrain. The key is to have a quick extension and slow rebound for drag radials.

I've been on drag radials only a few times at the track, compared to slicks I would much rather use slicks. Slicks feel a lot more smooth. Only exception is on the big end with low pressure you get slick dance

I get no dance at top end ![[Smile]](smile.gif) and I am not running tubes either. Going to tubes for 2015 season. Most of your dance is actually from bumpsteer.

I didn't have any dance this time, gotta get to 12psi or lower for that I believe

Here's a video of my first day at the track with the following mods:
E85 tune (404HP STD corrected, 390SAE)
Slicks/skinnies
Roush upper control arm
FRPP Dif girdle
E85 was worth 12HP on this car, so 12HP over stock + slicks/skinnies = 11's no problem.

I saw your dyno results for the afe, & k&n filter vs stock filter on the other forum. Did you ever do any 1/4 mile comparisons between these filters in the stock air box?
