So I think the 5AT drivers should have have our own little slice of Drag Racing heaven here on G35Driver. This thread should concentrate on tips, suggestions and technology to improve 60' and 1/4 mile times.

Realizing that tracks vary, let's post up some of our real world experiences.

I am also interested in hearing the results from those that are using AT Valve body upgrades, upgraded torque converters... as well as finding out if anyone is using a trans-brake.

I have a new Griffin Radiator that was custom made for the car and will be available soon those who want one. It is a direct fit to stock 5ATs (sedan and coupe)

I am going to run some tests on the engine temps, as well as tranny temps (it has a tranny cooler like stock). I am very interested in seeing if the larger all aluminum radiator will be sufficient for the harsh conditions at LACR. Depending on what I learn, I may need to look into a secondary tranny cooler. I will keep you posted once I get the data logging system installed and do before and after runs.

Cheers, Ted

 

I ran a whopping 15.1 at LVMS which would be about a 14.5 after you correct for elevation and atmospheric conditions. Only running a Z-tube/K&N drop in and Fuji Exhaust w/ Y pipe at the moment. It'll be interesting to see if there is any improvement after I get my Crawford plenum and cats (if they ever show up!).

 

bone stock 14.2 at 95.9 5AT 04 sedan here in florida

2.16 60' time

 

1) you have to pull the VDC fuse to be able to launch at an acceptable RPM (about 500 rpm higher than the stock stall)

2) cheap drag slicks on stock or mustang wheels - traction is a big issue - I used some crappy old worn-out slicks my last time to the track and couldn't break a 2.1 60' time... but was still running consistent 13.8's... (sea level, 85+ deg, ~260whp)

3) don't push it when it comes to shift points - in manumatic (or whatever you decide to call it) mode, the biggest mistake you can make is to hit the rev limiter - even when you do it to the slightest, you've just added .2-.3 seconds to your runs - as soon as the needle hits 6k on my car, I'm pushing for the next gear... shifting is the limiting factor on a 5AT, so you have to make sure you don't make it any worse than it already is...

4) if you are serious about lowering your times and don't want to go F/I quite yet, look into the TS "limited spec" reflash - for the money (around $400) you get the things you need (raised revlimiter, 100% throttle body opening) without having to worry about them screwing up your a/f mixture... this will allow you to make it through the 1320 without having to shift right before you trip the finish line... and one less shift can mean dropping your time a couple tenths...

I could probably go on and on about all the things I've tried and played with, but I've kinda given that all up because this car, simply, is NOT made for going in a straight-line... the alignment specs are the first thing that tell you that...

 

Jeremy-You have to come out to the track in about 2 weeks when we head back out there after Todd, Tony, Ian and I get our mods installed.
I've only been to the track once and ran 14.5 at i think 95mph. I'll post new times after my mods are installed.

 

How has the 5at been holding up for those of you racing it? I had always heard the 5ats were fairly weak, yet, I've never heard of anyone blowing one up yet!

Anyways, I have a low mile 5at for sale if anyone needs it....

 

Liked the drag piece as a former GN owner and racer at national level.If you have the same trans as we do(FX45),you will not break it!On the slow manual shifting there are fixes that will give you shift on demand(200 off limit).I routinely shift at 7100 and hit it near 6800.I have covered a bunch of 350Z 6sp...they were not happy and it handles with M3's,but I also have done a lot to it.
VDC,I do not recall if G's have a switch(we do ) but the fuse is better?

Ran a 14.669 @ 96.2 mph. (14.29 @ 98.79 mph corrected for 2200ft elevation.)

I guess the Crawford plenum and cats are worth the money I paid for them. I was brake torqueing at about 2000 rpm, but I never did get a real good launch. A little spin off of the line every time. 2.315 60ft time, but I'm still pretty happy about the results.

 

So I looked for the ABS fuse which is the one to pull for disabling the VDC - right? I can't find it in under the hood. Is there another name for it in some models? Anyone know the rating? I got a 14.2 without pulling it and it seemed as though I had enought traction to not set it off..but what if I lost some traction taking off? Would it have stopped power even after disabling the VDC by pushing the button?

 

Ran a 14.73 at 96.37MPH last night against roneski . That's a 14.35 at 98.96MPH at sea level. (I thought LVMS was at 2100ft...maybe I'm wrong) Bone stock too!

 

I looked up the track on a GIS topographical map and it said 2173 ft on the spot where the strip is located, (having access to county computers is cool), so I just rounded up.

 

I don't have access to that kind of data. You using your CIA connections again? Know we know!

 

i'm concerned as my best run was 13.7. i would also like to know where the fuse is located. i'm not worried about traction as i have an awd system. all runs were the same i just kept getting better r/t. my best was .065
and i do have the stillen valve body upgrade. i just ordered the torque converter and griffin high capacity radiator, so i'm interested to see how much it will improve my #s. but i was certain i should be running low 13's and not high 13's. i didn't run the sportstronic shifting. all my runs were in regular auto mode. i did do the trans-brake but the most it got up to was about 2500 rpm. so, where is the fuse located? also, does the trans-brake affect the tranny itself? this is my daily driver and the last thing i need is for my trans to go bad on me.
oh, and i did run on the stock rims/tires. would my #s improve by getting larger size tires? i don't seem to have any problems with tractions.

 

POWERHOUSEFAN,

The 13.7 sounds low. If you would have has a 6sp, I would understand as traction is usually a problem (from what I've seen on these forums). I would have thougght with an automatic and a supercharger, you would be low 13's minimum.
