Okay, I've done a search and didn't really find anything useful. I'm curious as to your opinions (experience really) on launching a stock or lightly modded (intake, FSTB, nothing serious) 3rd gen max. Right now I just rev it to 3500RPM, drop the clutch and hit full throttle. I leave the line REALLY fast like this. At least compared to the cars I've run with, er... beaten the snot out of (they were only fours).

 

That sounds about right I think.... Search HARDER! I know this kinda thing has been discussed in the past since that's why I think that's about right. Some people on here have their launch technique down cold and it's scary!

I don't have one cuz I don't race....

 

Alright, I've tried:

launch technique
best launch
takeoff
best takeoff method

I'm not getting much help.

I don't street race, that's illegal!

 

Maximadriver.com has a write up about launching/racing in how 2s

 

I have a stock 3rd gen. w/ a VG30 (soon to be lightly modded), he has a well-modded VQ30 and 17in. wheels/tires. His launch technique is dropping the clutch at 15-1600RPM, that'll bog my motor too much. Thanks for the input though.

 

what I do is give it enough gas to run about 2500rpm, then just dump the clutch and as soon as it bogs, floor it and you're off. minimal tire spin on the launch is key. if you dump the clutch and floor it, you immediately set the tires spinning at 20mph, and that hurts your launch severely.

 

Interesting... not as wild sounding as I had thought either! Does it make any difference you have an ACT though?

 

This may sound jerky, I don't mean it to be, but is that really faster? I ask because I've always heard a little wheelspin is good; that way when the tires catch you're going fast enough that you'll be in your powerband and won't bog your motor. Launching at 3500, I spin for about 20' and get traction right at 4000RPM = torque peak! Have you tried this at the track? I'm curious as to some 60' times I should aim for. Thanks. I like those wheels on your car too, they look really good.

 

I knew this had been discussed before so I ran the search too and found lots of good info by searching for "launch technique" and tons for just "launch"
http://forums.maxima.org/search.php?...der=descending not necessarily all in the 3rd gen forum, but still good info

hope these help

 

SWEET! Found a good one. Thanks guys.

 

I haven't used it at the track yet, but I've played on the street and it feels a lot better than just dumping the clutch. plus it's WAY easier on the tranny.
FYI, the guy who told me to launch like that has the fastest NA 3rd gen out there... low 14s all motor, 13.7 with NOS or something like that., and that's at the same track I ran a 15.0.
my 60ft was around 2.3.. he said his were 2.1 or 2.0..

 

Sounds good, I'll try it next time(in my driveway of course ). Thanks for the help.

 

you driveway is long enough to practive launching??? Friggin cool

 

LOL Sure, whatever...

 

If I try to launch with too much gas higher than 3K rpm it will spin the tires all day and give me some mean wheel hop.

 

I've revised my launch and now do something similar to what Matt described. The only thing I do differently is go ahead and floor it. I have a stock VG30E with factory wheels (heavy) so it bogs pretty quick. I lightly spin now for 6-8ft. and the tires catch at 3000-3500RPM depending on the surface. Puts me right at the beginning of the torque band. Cut my 0-60 by over a half second compared to launching at 3500RPM.
BTW, when I first got my new tires they were @ 40psi. When the tire pressure dropped a few pounds, I noticed slight wheel hop.

 

toldya it'll work.

lower your air pressure to low 20s if you really want to stick on the line. high pressure only helps in cornering response..

but yeah, since you've got a VG, you'll have to modify the launch a bit, but sounds like you've got it pretty good.

some people slip the clutch at 4grand, others dump it and go, then others dump it at 4 grand. the easiest on the clutch is the 2k dump, then bog and floor it.

FYI, even doing this, my car will spin for about 6-8 ft, then catch.. as soon as the engine hits about 3000rpm again, the fronts break loose again and I have to let off the gas a bit to keep from just smoking through the rest of 1st.

 

Sounds like somebody needs a little more tire...

 

i do the (at one point in time or another) the doug launch...3500RPM slip. RPM dont dip below 3k. just feather the clutch and gas. took me like 5 times to get it down..started out doing 1500rpm launches like that.
i dont get wheelspin or hop unless i dont pay attention and drop the clutch too fast.
i think it helps that i'm more or less trying to kill my clutch since it chatters horribly.
by the way, my mods are intake and UDP.
i have almost bald tires (pep boys special..) on stock rims.

 

i've spun wheels for like 150 ft in a parking lot reving to 6500rpm and throwing it into gear. i know its bad on the car, and ill have no tires left, but it sure is fun. but i got the best start at about 2500 to 3000.

 

I haven't any reason to do this yet, but reading about Matt's launch is really cool. Maybe I'm just really impressed by how "mild" the launch is. I've always thought the "best" launches were 3-4 grand and dump! This launch really does make sense judging from the VE dyno scan Matt posted, which has the torque curve lying pretty flat from 2300RPM and up.

 

If you wanna get the most power, you have to launch at peak torque which is i think 3200rpm on a vg...(BUT) since we dont have traction control u might spin some rubber before take off.

 

LOL, I do about a 2000RPM Doug Launch from almost any stoplight when I need to get over but couldn't 'cause of traffic. I actually enjoy stoplights. Plus when you get ahead of everyone else, you don't have to worry about cutting anyone off or vice versa, and you can hit the brakes if you have to w/o getting rear-ended. Plus it makes parallel parking (I live in an apt.) much less stressful.
