Well i made it out to the track again tonight.

60'.. ft 2.375
330.. 6.272
1/8.. 9.401
mph.. 80.52
1/4.. 14.354
mph.. 99.33

Compared to my last best at the track.

60' ... 2.306
330 ... 6.454
1/8 ... 9.739
mph... 76.92
1000 ...
1/4 ... 14.866
mph ... 95.65

took her to redline each gear and didnt lift to shift for 2-3 and 3-4. Seems my 60fts are killing my ET.

 

Your 60's are absolutely killing your ET's. You gotta ask 04treefiddy for some more launching techniques I guess. lol!

 

A 0.5 second improvement is considerable, but you are improving in the wrong place. To run 13.99 seconds or better, a 2.0 second 60-foot time would be helpful. Whatever technique you are using, alter it.

You can do it.

 

The tires on the car now on the rear are 2 differnt tires. One brand New and one almost bald. I will be replacing those before i head to the track again.

 

Good idea!

 

i have a feeling taht might help your 60ft

 

Stop powershifting-no offense but I doubt you can do it well enough to be beneficial if you cant launch correctly. Work on that first 60ft, what tire pressure/tires you running?

 

What does that even mean? Launching and shifting are 2 different things. Just because he can't launch, it doesn't mean he can't shift. Not everybody can do low 13s.

OP, work on your launch techniques. Vary them to find out what works for you. Also, having 2 same tires in the rear with about the same tread left will help you.

 

one of the tires is a nexxen 3000 that is pretty new looking and the other is a potenza tire that is bald. Its the tires that came on the car when i got it. Both are 265 series.

 

You disagree that a guy with 2.3 60ft's shouldnt be powershifting? Coming from somebody who used to do it, it is not needed, and in 95% of people I see/hear do it, its done incorrectly, only hurting the times...

 

oh god i will never do it again its the only thing i did differnt that night and improved my times quite a bit. Maybe thats not what improved my times. I dont know. Thats why i posted here to get some feedback on what could have improved my times. .069 on the 60' dont take away .5sec in the 1/4. It was hot and humid just like it was last time at the track so temp/humidity didnt hurt or help me any more then last time.

 

Geez, why racing on 1 bald, 1 crappy new? No offense man, but not very smart. Get 2 decent tires in a 275 size for those 9.5" wheels and go back. I guarantee you will do much better. As long as you keep practicing you will improve.

BTW-3hree5ive0ero-another reason I said he shouldnt powershift is because his 1/8 time is slow even given his 60ft, that tells me the 1-2 and 2-3 isnt on, so get it right with a lift shift first before you even think of PS....

 

Weather plays a huge role, 3mph in the first 1/8 mile is very significant....do you remember temps/humididty first time compared to last?

edit-lol you edited before I posted, something had to change other than you keeping your foot on the floor. Take spare, extra stuff out? Did you run on the same wheels, tires? Add/change any mods? Change shift points? How much gas did you run with the first time compared to the second time? See where Im going with this...

 

Despite the weather, the Z seems to be running good picking up 21 MPH in the second 660 feet.

 

Yea the first trip it was 87 and the most recent trip was also 87 according to the in car gauge. Humidity was around 50% on both trips. From what i can remeber. 04treefiddy may chime in with some exact number

 

Like I said, shifting and launching are two different things. He may suck at launching, but that doesn't automatically mean he needs work on shifting. I used to powershift too.

If you read his first post, he only powershifted 2-3 and 3-4. That means that his 1-2 shift was the main culprit for such a time slip. As you (Alberto) mentioned his 1/8 is extremely weak, which further proves his lackluster 1-2 shift. His back 1/8 isn't too bad. So his main three things he needs to change are his tires firstly, launching, and his 1-2 shift. The 2-3 and 3-4 powershifts aren't too bad, but I don't see how he can do that if he's shifting that slowly from 1st to 2nd.

He's only gained 18.81 mph in the last 1/8.

 

You cant rule the 2-3 out of that 1/8 time...we have people occasionally post they felt like launched awesome and post 2.5 60ft's, no offense to the OP, but we cant always trust the OP's who dont have experience, we can only trust the slips...

Regardless of it all, he has a better idea of what he needs to improve on its up to him now.

 

will post again when i get the new tires in and go again. Will get exact temp/humidty readings and such.

 

Always shift at redline BTW-in case your not already doing that. Id ditch that CAI as well, it doesnt work well with Crawford plenums especially the welded 1st gen like you have trust me I had that same set-up. My track times got better when I switched to a Pop-charger and I dyno'd 10whp more with no changes other than the intake-same dyno.

 

04treefiddy is goin to sell me his stock intake with k&n drop in filter
