Seriously Probably the Cheapest Option to create a Drag Machine is get a Second Hand Ute with LS1 V8 and Put on APS TT on it. That should do good 9 sec :P or even 10 sec still pretty good

I've added that to the 1st post so that you're in the 'list' as well.
Thanks DavidM - I noticed it last night and was wondering whether it was there all the time and I just missed it on first read (ie I'm going crazy) or whether you edited the info in.
Obviously the later - cheers.

[b] Just looking at that the 12.9 time, it's accompanied by an unusually low trap-speed for 12.9sec pass. Usually car's running 170 - 175kph trap-speed run low to mid 13s over 400m. Cars running in high 12s usually trap at more around 180kph. I pressume that you must have had a really good launch ... do you recall your 60' time for that run? Were you on road or sticky rubber?
Can't recall the 60' time. Biggest issue was wheelspin the entire run due to crappy little road tyres. Also with tools, spare and a full tank of fuel. I'm sure it could've done better. Just waiting for the current owner to have a run.

HiTech & Popcharger & RT215's

60': 2.042
ET: 14.005
km/hr 159.84

The RT215's did more harm than good. With the extra-stiff sidewalls, its hard to get traction down (even with a burnout to get them warm). Even when I snap-changed into second, I'd get a fair amount of wheelspin on the strip.

There are 13's in the car, since that's not my highest trap speed.

I'd say that the best launch is to slip the clutch. The second best time was my last run at a 14.1, where I intentionally rode the clutch and got it away with only a sniff of wheelspin.

Strangely, its the times were I popped the clutch and smoked them up where my trap speeds exceeded 100mph Since the 60' times aren't the best, I must have just had good gear changes further up the strip.

"I swear, officer, its all factory options!"

Understeer is when you hit the tree with the front wheel.
Oversteer is when you hit it with the back.
Horsepower is how hard you hit the tree...
Torque is how far you drag it...

That's a better 60' time than I had with the auto!!! Sounds like you've worked out how to launch. My best 60' was 2.059 with an ET of 13.914. And a 2.095 on my fastest ET 13.816.

To be honest, that launch was an accident. I didn't mentally think, "I should do this" and then execute it.

I just lined up, waited for the lights to go, and then launched and got lucky.

I'd adjust the revs I'd clutch-up from, but for the most part I'd just pop the clutch and then work the throttle. Some runs I'd ease the throttle down better than others to limit the wheelspin, but it wasn't conscious.

hmmm, I can't edit my posts anymore?! I was going to update the original post with this info, but it seems that I can't. Maybe Zuffy can?

btw, that is an awesome 60' time. I'm guessing that if I could run the same 60' time, then I'm be in 13.7s. What were your other 60' times?

I'd say that different strips have different surface/grip and hence require different launch technique, but it's still be good to hear what exactly you did.

Even when I snap-changed into second, I'd get a fair amount of wheelspin on the strip.

I get that with the RE040s. Though, I get it anywhere ... on the road, or at the strip. Though, with ther R-spec rubber I have enough grip not to get wheel-spin on gear-changes. I'm guessing that a lot of it is due to the size of the 350Z's flywheel as the revs do not drop quickly enough to rev-match on spirited up-shifts.

Regards,
David

My average 60' times were around 2.15sec or so.

Don't know if I'll run the car down the quarter again; it wasn't that interesting and I did it for a "give it a go" idea.

There's off-street drifting at Oran Park, and I'd be more likely to take my car out to that then drag again.
