Default So yea went to the track last night (Greddy TT)

It was a really great night. Not too many cars. No crappy civics for once and it was nice and cool out, in the 40's. Brought my drag radials out for the 1st time.

12.4 @ 111 with a 3rd gear screw up


Broke the axle



End goal for this Z is 550-600 rwhp so I guess it's time to get some stronger axles...

good thing they are only $70 shipped on ebay and even cheaper if you can soruce them on car-parts.com locally.

You broke going into 3rd gear?

this should be in the drag forum as well, not FI

Yea 111 seems slow for a 12.4. I ran a 113 with a 13.3 with lots of wheel spin. I broke my supercharger cog belt when I went so I share your feelings when you go to the track and don't get to get a few runs in. Axles are cheap no big deal.

There is a thread about a group buy on DSS pro axles now is a good time to look into it.

I don't have a scanner. The first run I did a 12.9 at 111mph but I didn't do a burnout. It spun all through first gear but hooked up the rest of the run.
The time slip reads:

60': 2.080
330: 5.638
1/8: 8.509
MPH: 85.78
1000: 10.906
1/4: 12.928
MPH: 111.44

I did a total of three runs with the last one being at 12.4 at 111mph but messed up on third gear. Went into the third thinking I missed it and put the clutch in but realized it was in gear.... cost me .2 on the time im sure but I think it is easily capable of an 11.9... I thought it was strange in regards to the mph as I did a 13.3 on street tires at 115mph with a 2.3 60' but I spun through first and second (This was a run I did about a month ago). The results from the 12.4 run are as follows:

60': 1.870
330: 5.351
1/8: 8.162
MPH: 88.09
1000: 10.496
1/4: 12.495
MPH: 111.27

The drag radials really do make a differance. It was the standing burnout that broke the axle. Broke the passanger rear right before the spline goes into the hub.

I want to go on the "Run 7" Dec 15th but I don't want to go with stock axles. I am thinking about putting a stocker on for now and upgrading after christmas to the driveshaft shop stage 2 with a nismo or cusco diff.

Thanks. I will try to give him a call on monday. I really want to go ahead and drop the bomb to get the upgraded axles b/c theres no point in going to the track on street tires now that I've seen what it can do with the drag radials. lol

I ran similar times 12.7 @112mph with a 2.08 60ft on street tires with around 400whp what altitude are you running at i am at a high altitude and that usually kills the trap speed a bit.

I guess the location on the left gave that away I am over 2400ft and density altitude is usually over 3000ft in Orlando i would expect it to be close to sea level so i would expect some better trap speeds. What size are your drag radials, i tried DR with a shorter over all diameter than stock (all that was available at the time) and it caused me to have to shift right before the finish line or I would hit the rev limiter and I also noticed i lost about 5mph.

Well if the temps were in the 40's as mentioned........the DA very well could have been negative. Certainly no more than 300-400'.
