gonna hit up Sacramento raceway tonight.
heading up there with my 04 silver z 6 speed manual, its basically stock except CAI.

its gonna be my first time with the Z.
any hints of what RPM i should be launching?
i tried launching on the streets on closed roads of course, i think 3K RMP and feather first?

any suggestions would be appreciated.

 

I suggest you search for tips from experienced drag racers. This has been asked and answered hundreds of times.

 

You may want to go as low a 2500 rpm on street tires. I've had plenty of spin and wheel hop at low rpm launches on street tires.

 

isnt that what im doing? :P
hopefully ill get a lot of runs in so i can see what launch works best.

 

Agreed......I tend to launch in the 2700 range.

 

Goodluck! Hopefully we'll be seeing a 13 second timeslip from you.

 

Go real fast like this…varoooooom…varooooooom. That’s what I do.

 

+1

 

We should make this post a sticky. Seriously.

 

So how did you do?

 

still a bit early on the left coast.

<--in for results

 

so i made my runs.
kinda happy but could be happier haha

i NEED to get my 60' down
about 80 degrees out.

first run:
.517
2.261
14.243
100.83
(had passenger in the car, launched at about 2K)

second run:
.535
2.331
14.532
102.198
(got a little nervous, launched at 2.5K and spun first and second)

third run:
.581
2.427
14.343
102.618
(launched around 2K, spun first)

fourth and final:
.682
2.324
14.268
102.528
(launched at around 1.6k, gripped pretty good)

i was surprised at how low i launched and got the better time, overall im happy for stock, i was REALLY hoping to see some 14.0-13.9 but it'll do for my first time in the Z.

also, tire pressure was pretty high.

i did get to see one of these



he ran 11.9

 

Good mph, but need some work otherwise.....it will come with practice. A while back I was running 13.7 at 102 with 2.0 60's. So you have plenty of speed to go 13's. Track prep was have been **** poor if you were spinning through second with a 2.5k launch.

You mind posting the whole slip from your two better times. It is much easier for everyone to see whats going on.

 

You will do better next time.

 

Launch at 4000 rpms, slip clutch a bit and once you get traction nail it. That should get you into the 1.9 60' range.

 

Some of the Z32 guys go to Sac Raceway on Saturdays... A bunch of us routinely go to Sears Point Wed night drags in Sonoma as well. Keep practicing.

 

those traps of 102+mph are good enough for 14 flat, work on your 60 foot time. Also, theres no reason that you should be spinning 2nd gear with a stock Z, (or 1st for that matter) work on throttle control when engaging each gear and you'll see better results.

overall those are good numbers for a first time track day, with a 2.0 60ft and those 102 traps, you'll see a 13.9-14flat

good job.

 

sure thing, when i get home from work.

and thanks guys, i didn't even attempt to launch at the 4K range, i figured if i was spinning when launching at 2.5K then what would happen at 4k!

i think my big issue is the tire pressure, it was too high in my opinion.
i didn't have the gauge thing to lower it so i said screw it..

ill be going back in about two weeks with the new headers installed.

sucked that i was the only Z there..

 

dont be scared to lauch it and get a little spin, u just dont want hopping...2700-2900and the right feathering should be the sweet spot depending on the track

 

Sacramento is a fast track, so if you went to Infineon (Sears Point) your times would be about 2/10's slower. Your car is capable of running at least a high 13 at either track. If you ever want to go to Infineon, PM me and I will help you get 1.9 sixty footers.
Occasionally the Z Car Garage has a group at Infineon and you will have all the help you need. Check the norcal section on this board.
