Search, i remember a whole thread on this from the 6mt guys. I'm awesome at flooring it and flipping the paddle

I launch at about 1700 on 7at. My best 60ft is 1.920 so far.

Huck

I've searched and read a few different pages, I was just wondering if anyone here had any other tips or tricks. The general consensus to be launched at 3500 rpm, and drop the pressure in your tires to about 28 pounds.

Huck, it's trial & error. Depends on the track conditions too. What kind of tires are you running? Camber? Suspension?

I got my best results doing it this way:

-Rear tire pressure = 25 psi (although I felt like I lost a mph or two this way)
-Do a quick 3-4 sec burnout (I'll take sh*t for this) - puts a little heat in the tires and gets all the water out of the grooves
-hold 4,000 to 5,000 RPM at the line - not easy to "hold steady" with the drive-by-wire, i usually end up kinda of bouncing it around there
-'quickly' let out the clutch (not dumping it, but not slowly slipping it either)
-the split second the rear starts to squat, put your foot into the gas pedal HARD. if you spin at this point then your run is FUBAR. If you get on the gas too late, you'll get wheelhop.

With factory suspension, Sport wheels & tires, stock clutch I managed to cut high 1.8x to low 1.9x 60ft launches. Best I ever ran was 1.85 60ft. This was at PBIR down here in Palm Beach, IMO a very sticky track.

Side note: I'll never forget the night I was running low 1.9x and a few high 1.8x 60ft launches and some random hot shot at the track was critiquing my time slips. He said that I "need to work on my launches" and I'll be able to get some faster times. I asked him what car he was driving that night.... "oh that GT-R over there is mine".

I leave my rears at 35. I tried 30 twice and same 60ft but slower trap for me.

Like they say at the drag strip. <If you're spinning you ain't winning>

Thanks man I appreciate it, exactly what I was looking for.

Currently running Forgestar f14 11" in the back, Michelin PSS 305's, -2.6° camber I think. I just got camber arms in the mail today do those need to be installed and then camber should be like -1.6-1.8. I'll reload my trunk, drop a little tire pressure and see what happens.

like presto said, camber can make a big difference. I've made good passes on factory alignment and for a while tried -1.0 rear camber. It didn't seem to help as much on track launches, but definitely helped a lot on the 'street'.

Lol, your story reminds me of the first time I went to this track. There was some kid with a Stang GT pulled up in the staging lane and talked with another Stang guy about my Z like I couldn't hear him. They were laughing at my "slow @ss jap shît" and how he was gonna burn me.

I smoked his *** 6-7 times that night. He wasn't happy.

if you are dead set on better times then lose the camber.

i've thought of this many times but i DD my Z so it would hurt the overall drive of the car since it's set up for handling and it's too fun to throw into turns to change it. the Z is camber heavy in the rear so that mean less tire is contacting the track for traction on a drag strip launch. factor in the squat on the launch and you lose even more of the contact patch.

Yeah, there will be morons at the track for sure.

My favorite was a while back when I was running 'stock' in the dead of FL summer. Had not made a pass yet and a younger guy in a Cobalt SS walks up to me.

guy: "hey you wanna run my car?"
me: "sure, what you got?"
guy: "that turbo cobalt... everything chevy makes is a POS and this is the only one that's any good"
me: "cool. so tell, me why did you pick me to run?"
guy: "oh, I usually run about the same times as 350Z's"
me: "so what kinda times do you run?"
guy: "you don't want to wait and see???" (cocky grin)

We lined up and and I ran a decent time... 13.6 @ 105?. He ran a 14.7 @ 107 mph.

me: what happened to you on that run?
guy: Let's run again, I'll turn up the boost.

I think I ran the same time again, he gained maybe a 0.1 et / 1mph.

Side note: The rules at PBIR are: 13.999 and faster requires a helmet. I knew he was full of sh*t when he pulled up to line WITHOUT a helmet!

I don't think your response helps him much, that and you probably did that with slicks + 7AT... he's got street tires and 6MT.

they say the same at the local tracks here about helmets but rarely enforce it.

sidenote i almost took down a viper last friday. hot and humid so the Z wasnt running well.

lost by .2 seconds

You didn't have to drive a Dodge home; that makes you a winner.

FPenvy
