^already been through that, but not because of drifting and stuff, because i would go to the drag strip every 3 months with my old tranny. Still going on stock clutch at 50k.

 

LMAO! i did lots of drive away burnouts on the 06 5AT sedan loaners.....

 

^loaners are fun.

 

must have been the extra 20 over- rated horsepower

 

in an AT (at least my sedan) you can't brake trq... if you push the throttle and brake at the same time the ECU plays tricks and cuts the power (safety thing )... you loose a little time in a 1.4 mile... that's why I get frustrated only being able to launch off idle at about 650rmp...

There have been several solutions - pulling the brake fuse, disconnecting the yaw cable, and unplugging some primary (grey) plug in the break reservoir area under the metal box...

I don’t do any of those things... there is a bypass switch DIY mod posted on my350Z (maybe out here somewhere too)... but KPTechnologies had some buzz about a production mod to address this - I don't know if it fizzled or if it didn't really address this issue so they aren’t marketing it that way - they just released a VDC mod that stores the on/off setting so when you start the car it will be in same mode as you left it when car was turned off - but simply turning off VDC won't fix this particular problem...

I've had talks with another manufacturer/vendor about doing this mod, the idea was well received but I haven’t heard of any progress making it happen.

 

With my 03, brake torquing i mandatory to acheive the best 1/4 mile ET. MPH isn't affected much, but ET is. Launching at idle results in 14.5-14.6 and 2.3 60 foots. Launching at 2400-2600rpms results in 14.3-14.4 with 2.1 60 foots. At the track, I'll barely chirp a tire. On the street, I'll usually spin 10 to 40 feet depending on the street surface and ambient temp.

My launch technique is this:

1) Foot on brake
2) Foot on gas
3) Foot to the floor on gas
4) Release brake about 1 second later (~2,400-2,600rpm launch)

I get a slight bog until the rpms hit 3000 or so, then the car really starts to move. Here's a typical launch on asphalt on a 95 degree day to give you an idea of the spin. You'll also see that both tires will leave equal marks even though my car doesn't have an LSD. The tires are 215/55R17 Avon M550s.

 

Like others have suggested, do the burnout switch mod:

Just remember this mod disables your brake lights so dont forget to turn the switch back on after your done burning out.

 

Throw on some donuts. j/k

 

I like the dog pic....

 

hmmm, i burn out at the race track without the car moving...i can get the car sideways

off idle my 60' are consistently 2.1+... off idle I've run 14.3s... maybe for your car what you mentioned is true... certainly not mine.

 

Good for you. I thought you were outta here?

 

???? outta here?....

Dave, if you are going to report what your car does that's fine - but don't state it as if these cars in general do what you are saying... I've tried the brake trq technique at the track and it simply kills my launch, 60', ET - everything. It just is not the best method (at least with my car)... however, I have been successful launching off idle and achieving way better results than what you posted happens.

Granted - if I could brake trq and rev to 2500 or so without the ECU phucking everything up for me and cutting power I'd see much better results... but the results I see launching from 650rpm are not what you are reporting.

I just wanted to make it clear - in case someone else has a car that reacts the way mine does... so they are not mislead to assume all will react the way yours does.

Is that okay with you?... Should I PM you before I post to run it by you before I mention it?

Give me a break dude

 

In our recent discussions, you flat out said "you were done with this site".

Also, taken straight from your first post in this thread:

I don't know what your car's problem is because it is not common for these cars. I've had three RWD loaners now, an 04, 04.5, and an 05. They all could handle a 2,500rpm launch without a hitch. The 04.5 and 05 actually responded even better than my 03. The 05 would actually roast the RSAs on most anything over 2,000rpms.

Your initial post makes it sound like it's impossible to get better 60 foots with a brake torque launch much less a 5AT is actually capable of such a launch. I've now driven 4 RWD 5ATs (including mine) and they all respond the same. I've tried various types of launches at the track and brake torquing always results in significantly stronger ETs. Hell, even Motor Trend and C&D note that the best times in their G35 test cars is achieved with a brake torque launch.

Your car might be able to launch off idle quite well because you're running 3.7 gear which offer about 15% more torque multiplication in 1st gear. It might also be why your ECU is keeping you from brake torquing?

 

DaveB - I’m sorry to call you less than intelligent - but in this case you are.

I never said, "I'm done with this site". Are you high?... I promote this site more than you ever would... I tell every G I see modded about this site and I donated my $100 April winnings back to this site. Additionally if you read the thread about business cards to promote this site you would realize my support... What do you do for the site - other than try to get people with good intentions to leave because you are a pain in the @ss????

You are extremely delusional!

As far as "my" car reactions... you quoted a post that states "my car".... I was telling people how "my car" responds...

Wow Dave... you are really disturbed.

BTW - I've driven every sedan 03 (doggie door) thru 07 as well as the 08 coupe... stop with your BS DaveB... you do NOT have more experience or viable information about these cars no matter how much you want to deem yourself king. "Fool" is a better term.
