Newbie -> "launch" the car help

What am I supposed to do from a dead stop?

No fancy tires
Only NA engine
4.4 transmission

Is this right?
Warm up the car

Dead stop
Rev the engine to about 2000 - 3000 rpm
Let out clutch kind of fast
When clutch bites floor the gas and shift like a pyscho

Rolling
Downshift to get into power band and go nuts ?

With 4.4 transmission car is easily in the 2-3k rpm range without even trying but slower to get off the line than my 3.8 maxima :s

Or does that kill your transmission?

When I 'launch' a car I basically floor the gas simultaneous to dumping the clutch. Of course, without incredible grip, this can result in just sitting there spinning the tires. In that case, you would gradually modulate the pedal into WOT as you feel the grip improving. Sometimes doing this though you can bog the launch if you don't get it into WOT soon enough.

And yes of course when you're already driving you'd have to downshift to get into a better power band. For example, at 75 mph for the 3rd gen, downshifting to 3rd puts you in a very sweet powerband to then gun it. I always make sure to rev-match of course when doing this downshift.

I'm not sure what you mean by 4.4/3.8 transmission

Aren't you supposed to avoid dumping?

With the 4.42 final drive ratio transmission the maxima is in the 2,000 - 3,000 rpm going from 0 - 100 km/h gears 1 to 6... This is power band range yes??

It's winter here and I'm using all season tires but I can't shift good at all... Losing to Honda Civics >

I wasn't 1000% trying because transmission is new ><

It's very difficult to get it going compared to the oem imo......

need to master N to 1 without destroying car......

Well there's lots of things that are hard on cars that one 'should' avoid, including dumping the clutch and racing the car around in general. But then again you asked how to launch the car.. so...

I still can't comprehend what you're asking with your second line there.

There's no "safer way" or "least harmful" method?

At what RPM should I be shifting?

Thank you

Well yeah, least harmful - and may times this is necessary for traction anyway - is to basically do as you described in your first post. Rev it up to about 3k or so, and rather than just "dumping" the clutch, let it out a little slowly (and that's a relative term, it still needs to be pretty fast so that it grabs) and rather than being totally floored on the gas pedal immediately, you'll want to gradually press the pedal into WOT. It's very hard to describe but you can really many times take off a lot quicker this way because you're not sitting there stationary spinning through most of first gear.

If you're learning/practicing, you don't have much choice but to be a little hard on it. Don't worry about it, it's not a China doll. It's not going to fall apart from some hard take offs.

Assuming you are racing/wanting to go fast, you should be shifting just prior to redline

Tricycle George tricycle. If you launch your tricycle yes honda civics will win but you can shift with foot power and not worry about destroying a good tranny or car for that matter.

I tried revving to 3000 then letting clutch out slowly but ultimately the car would bite and rpm fell to ~1000 rpm

I gave up due to fear of frying the transmission

Rpm is always going to fall once you let the clutch out. It's falling because with clutch in and no load motor is going to rev to whatever rpm. Once you dump clutch now there's load on the motor therefore rpms with drop. You have to find the sweet spot.

Basically do what I do DD but faster with higher revs then?

Kind of. You just have to play around with it.

If the rpms drop too much, give it more gas. If the tires spin, you can slip the clutch more or give it less gas.

We can only give you so much advice. Unfortunately I can't hop in your car and show you how to do it.

Hope this helps.

I'm killing the tires

FINALLY successfully did this :].

Held rev at 3000
Let clutch out like I would during DD
When it bite I let the clutch out too slowly (I think a little too slow )
Torque steeeeeeeer
Car went flying

Is it better to rev at a slower rpm for gears 1 and 2 then ~6000 rpm for 3 to 6? Or 6000 rpm 1 through 6?

well if you’re losing to civics, something is wrong. Máximas can take a heavy beating. I’ve had my 99 Maxima for about a year and have been ******* the absolute c*** out of it. Usual maintenance for older vehicles has been taken care of but nothing major. I drive like a granny when cruising town. I don’t really go on the highway much, but when I spot someone driving recklessly or just overall fast. It’s go time for me, I drop to second with the rpm at about 4K. Best torque ratio is between 3-4K especially in second. You will not lose to civics if you bang those gears out. Until you hit the rev limiter, you shift to third or fourth. I’ve won quite a few races, but lost many. Stock cars aren’t that fast compared to v6 máximas.
